Connecting the Dots: Pre-Process Validation to Production Process Monitoring 

By their body language and words, companies say it all;

“Why monitor our crimp process with more than the most basic of tools? After all over the years, our products have performed with no problem without adopting more than is necessary?”
On the surface this may be true. But lurking under the surface are problem issues that can costing your company now and in the future.

Consider the following scenarios:

  • Internal process rejects or rework that goes unreported. Like a bad crimp that is simply clipped off and an operator re-strips the wire and crimps a new terminal to the wire. Adding variation to the process by manually processing the wire without validating the results.
  • Mismatched wire and terminals. A mismatch between the terminal and wire, especially the terminal being too big for the wire can cause excess variation in the crimp process and electrical performance issues like high resistance. Process variation is a hidden cost to production while high electrical resistance is a potential long term product failure.
  • Worn production tooling creating batches of parts which can create assembly issues upstream. Deformed terminals from compensating for worn tools are one problem.

Mainstream OEM terminal suppliers invest an extensive amount of resources to ensure the connector they design performs properly on the factory floor and in the actual product over it’s life expectantly. They provide the processing test requirements to assure the terminal is assembled properly. So why do so many companies not validate their assembly to the recommended specifications, never mind monitor their assembly process?

Consider the Cost of Inaction (the status quo) as a reason.

So let’s talk about the transition from pre-process validation to process monitoring. For that you need to think about this fact:

In a lab environment, processes are controlled and highly repeatable. In a production environment, external variation exists which can affect the final product quality.

Without real time process monitoring, depending on single or spot in-process inspections does not give you any solid information on the capability of the terminal crimp process. And that is a missed opportunity for process improvement which can provide improved efficiency and reduced process costs. Which is the Benefit to the Cost of Quality.

One important point to remember is that process monitoring tools do not improve quality in and of themselves. But they can raise issues on individual setups which should be reviewed at the time. Otherwise you can be trapped in the CFM Cycle.

Using the right tools in crimp development and validation in addition to process monitoring can provide the opportunity to improve crimp quality. Establishing a base line of quality and deploying a quality improvement strategy can reap great dividends in cost reduction, customer retention and potential for new customer acquisition.

Crimp Quality Solutions: Training and Support Services

Training, Consulting and Support Services are an integral part of Crimp Quality Solutions, part of the WireProcess Specialties portfolio of solutions for processing wire assemblies.

One of the strengths of WPS for almost four decades has been in the supply of terminals, crimp tooling and crimp monitoring systems. It has become evident that a comprehensive offering to our customers is needed. Which is beyond the physical acquiring and deployment of components, processing and process monitoring monitoring equipment.

For example, consider this statement:  Installing a Crimp Force Monitor does not improve quality. See our article: Crimp Quality Monitors Do Not Solve Your Crimping Problems.

Our engagement starts first with an assessment of your current crimp process. We can perform this either in house or through a virtual connection.

Training material is custom tailored to the company’s needs with one or more of the following topics:

  • Pre-production crimp validation
  • Crimp Process equipment set up
  • Pre-production crimp testing
  • In-process monitoring
  • Documentation

Training can be performed in house or via webinar.

Crimp Quality Solutions Support Services are a vital link in the implementation of a Crimp Quality improvement strategy. Our in house Crimp Cross Section lab gives you a start in documenting crimp conditions. Crimp Press Analysis assesses the condition of your crimp presses, a critical component of your crimp process. Crimp Cross Sectioning is a vital tool in validating and process monitoring a crimp. Cross Section provides a peak inside the crimp and tells a lot about the performance of the crimp process and inherent variation.

Crimp Quality Solutions provides you with end to end support in your terminal crimp process. Let’s Get Started with your crimp process.

 

Crimp Quality Solutions: An Overview

Back in the day, training for personnel was readily available from suppliers or internal company experts.  Does it seem that access to training and has become scarce.  Do you sense the “brain drain” as knowledgeable people are retiring and not being replaced? Perhaps Crimp Quality Solutions is for you.

Crimp Quality Solutions is part of the WireProcess Specialties portfolio of solutions for companies processing wire harnesses and electrical assemblies which include a terminal crimped to wire.

Consider the following questions:

  1. We only make a quick measurement of crimp quality and a visual inspection pre-process.  We do not have any idea what the capability of our crimp process is.
  2. We have received a review request from a customer about our crimp quality or have had to address rejected wire harnesses with faulty crimps.
  3. We have installed crimp monitors to our bench presses or automated wire processing machines and have chronic error signals from one or more crimp applicator set ups. As a result, we have opened up CFM tolerances to stop the error signals or completely shut off the monitors.
  4. We want to establish a baseline of our crimp quality and improve quality over time.

If you answer yes to any of these questions then Crimp Quality Solutions is for you. We offer end to end support of the crimp process. Our support covers three areas:

  • Training and Consulting.
  • Support Services.
  • Quality Validating and Monitoring Technology.

We start with a free assessment of your current crimping process. We review the assessment and where required, consult with our industry experts and provide a proposal that covers one or more of the above areas of support.

If you do not measure crimp quality as part of your quality system, you are at risk of product failure, costly rejects or recalls and reduced customer confidence. Because it has not happened so far does not change the fact it could in the future. There is a cost of inaction when it comes to product quality.

There is a positive cost to action and we are ready to respond and support your crimping process. Let’s Get Started.

 

What can other industries learn from Automotive standard USCAR21?

USCAR21 Title

USCAR-21 is the quality standard that can strike fear into companies who deal with automobile assembly companies.  USCAR-21 is a universal standard which applies to suppliers of electrical assemblies to The Ford Motor Company, General Motors Corporation and Fiat Chrysler Automobiles.

Companies who are not involved with automotive wire harnessing can quickly dismiss this standard as not applicable to their business and industry. Although this is true, some of the components of USCAR-21 are valuable and can be directly applied to the validation of wire terminations for any industry. Companies not considering some of the key features of USCAR21 can miss out on the benefits to quality improvement.

We will drill down to reach those best practices which can be applied to your company.

Prior to the formation of USCAR-21, each automobile manufacturer had their own testing and validation standards. The adoption of a common standard meant more efficiency in the testing process, especially for suppliers who provided wire harness across a number of automobile OEM’s listed..

The USCAR-21 standard includes mechanical and accelerated environmental tests which are designed to duplicate potential operating conditions a wire to terminal connection can experience through the expected life cycle of an automobile. Demands on the electrical system are increasing with smaller wires carrying communication signals and larger wires used in current load in applications such as EV batteries. A comprehensive standard was required to address the performance requirements through the full range of harness size and complexity. At the same time, to reduce some of the bureaucratic burden from the supplier end.

Lets bring USCAR-21 down to it’s most basic objective: Electrical connections must maintain low electrical resistance through the expected life span of an automobile. This is achieved by adhering to critical crimp design and validation criteria.

Ultimately, monitoring the crimp process during production is important to ensure specifications from the validation stage are maintained.

Here are a few considerations to the actual electrical crimp.

  • The terminal supplier’s recommended crimp height and width is the starting point of all initial and pre-production crimp validation. Wire terminations should perform acceptably though the tolerance range of the recommended terminal crimp height.
  • Crimp compression, the process of encapsulating the wire into a crimp barrel with sufficient force to deform the strands from their round shape is a major factor in acceptable electrical resistance. Compaction of the strands by 15 to 20% provides the best opportunity to pass electrical resistance testing. There is a direct correlation between the amount of wire strand compression and electrical resistance. Especially leading up to and through the above compression range.
  • Crimp barrel and wire size must be carefully matched to ensure the optimal compression is achieved. In combination with the proper crimp tool design. Factors indicating a poor wire to terminal match:
    • Wire strands under-compressed.
    • Strands not evenly distributed in the crimp barrel
    • Crimp wings curl and touch the bottom (floor) or sides of the crimp barrel.
    • Crimp wings with a gap at the top, with strands not fully encapsulated in the crimp or pressed on top during the crimp process.

  • Serrations in the crimp are designed to break oxides present on the surface of wire strands, providing better electrical connection. Also to assist in the mechanical secure-ness of the crimp.longitudinal cross section 5

Consideration of measurement methods.

  • Crimp Height is the primary test factor in a validation and in-process measurement.

  • Tensile (Pull) testing is a secondary testing method to ensure the wire termination has “sufficient mechanical strength”. It is not a determining factor of electrical performance as low or high compression can affect not only mechanical but electrical performance.WhatsApp Image 2016-11-10 at 9.31.28 AM
    • In all cases, insulation support on terminal crimps must be peeled back or not crimped at all for pull testing. Pull test readings should be made on the wire to terminal crimp only.

WhatsApp Image 2016-11-10 at 9.33.24 AM

  • Crimp Cross Section un-covers the actual crimp condition from wire/terminal match and crimp tool profile. As well, crimp applicator setup can be checked (i.e.: terminal feed position).

cross-section-273

  • Visual inspection criteria ensures the proper machine setup provides the best crimp. Visual factors of an acceptable crimp are:
    • End of wire protruding on the contact side of the wire crimp. Known as brush.
    • Insulation and wire (roughly 50:50) present in the “window” between the wire and insulation crimp.
    • Bell mouth present on insulation side of the wire crimp to protect wire stands. Bell mouth can also be present on the contact side of the wire crimp.
    • Insulation crimp wings should not penetrate the insulation and make contact with the internal stranding and should fully encapsulate the insulation.

Electrical and Electronic devices that are not assembled into an automobile will have their own performance parameters. In most cases they are not subject to temperature and humidity fluctuations that are present in an automobile. But totally dismissing good crimping practices and not applying some of these best practices can expose your products to premature failure which carries a high cost (and liability). That’s the important factor when Acting on the Cost of Quality, understanding the Benefits and avoiding the risks of Inaction.

Counting the Cost of Quality: The Benefits

Every Decision has a cost.

This is the third and final part of our series Counting the Cost of Quality. In Part One, we discussed The Cost of Action, those decisions that are made on the basis of acting on information that has been provided. In Part Two, The Cost of Inaction covers the implications of not acting. Part Three will cover the Benefits.

As a company with a bias towards action, we consider the benefits of action far surpass the benefits of not acting. But acting after thoughtful analysis of the decision being considered. We acknowledge that any decision even a decision to act, carries some risk. Decision paralysis can take hold when the fear of making a decision is greater than not acting, part of the reason the cost of inaction can be high. We can consider as many variables as possible but there will never be enough information to completely mitigate risk from a decision.

So to consider the benefits of making a decision to act, let’s use an example of acquiring a Crimp Cross Section Lab to enhance your company’s quality process validation and monitoring capability. You have considered the upfront cost which includes the actual cost of acquisition, employee training and integration of this system into the company infrastructure. Consider the benefits which can apply to this decision:

Internally, individual employees directly involved with the new acquisition will be happy to see the company has provided new tools to help in their day to day work. As a collective, employees feel a higher sense of security that the company is investing in the company’s future.

As a company, new tools that are used can improve the overall quality of output. In the case of quality validation like our example, this provides a measurement tool to track the quality of output. Any tool to measure progress is critical (and may I say essential) to a company’s survival never mind growth.

Externally, existing customers will have a higher chance to keep existing business with your company when they see investment in infrastructure. Investments that can benefit them. And provide new opportunities to grow the business relationship through added contracts as they come up.

Potential customers will be more driven to work with you as they see investment in new infrastructure. In some cases, new processing or validating tools (like Cross Section Analysis as described) are minimum gateways to a business relationship even starting. For others, they will see your company set apart from your competition as internal investment in hard processing systems (capital) and training (human resources) are made. Where the investment is emerging and state of the art, you separate yourself from others who have not advanced as far as your company has.

These are just a few benefits to making the investment to improve quality. I am sure there are other direct and indirect benefits not mentioned.

This series was created to illustrate the opposing sides of a decision, to act on a decision or to stay the course (which in and off itself is a decision). You may not be in a position to be part of the decision making process of the company you are currently employed with. But regardless, you will be affected by any decision (or non decision) made.

In a perfect world all companies will err on the side of action and see the positive aspects of acting to improve the company. But some will stay the course and not act. And may not see any difference in the short term. The same with an action decision, there may not be a positive result in the short term. But the difference will lie in the long term implications. And if I were to consider the long term survival prospects of any company, the bias toward making positive action on decisions would make me more confident in that company’s future. Certainly that is the goal for our company.

Global Technology Partners in Focus: Crimping and Stamping Technologies

cs-1

There are watershed moments in a company’s history, times when a single decision can change the course of a business. Such is the case with WPS in the early 90’s. When we were looking to enhance our product offering with new product lines and technology, a brochure about crimp monitors arrived in the mail. The decision to inquire about this technology led to the start of a business relationship that exists to today. And which also led to two other significant connections in Schaefer Megomat and Stapla Ultrasonics.

I am pleased to introduce Chris LaRue. Chris is the President of Crimping and Stamping Technologies and one of the hardest working people in the wire processing industry.

WPS: Thank you for taking a few moments to speak to us today Chris. You have spent your career in crimp technology. Tell us a little about your background.

CL: I am a mechanical engineer by degree and started my career at Amp Connectors (Harrisburg PA) in 1984. I was a die engineer in Amp’s high speed stamping facility. I was the first engineer to be hired in the die engineering rotational program. This was a two-year training program with assignments in stamping, injection molding, plating and assembly.

After seven years at Amp, I had an opportunity to join a small start up company supplying stamping monitoring systems.

After a few years, I made the move to form C&S Technologies. 

WPS: Can you provide a rundown of the product offering through C&S.

CL: C&S supplies solutions for validating and process monitoring for wire harness manufacturing.

WPS: Where are your facilities located.

CL: Our facilities are in Pittsburgh PA, Chihuahua Mexico, Juarez Mexico and Queretaro Mexico. Internationally we partner with True Soltec in Tokyo Japan. Also CTEC in Munich Germany. 

WPS: Automotive assembly has driven advances in crimp quality technology. Although there are several advances in monitoring and validating the crimping process, can you highlight a few significant technology advances

CL: Crimp Cross Sectioning has been a crimp development tool for several years. But it has been limited to a lab environment. Now because of cost reduction, simplicity and speed these systems have found their way to the production floor as an additional set up validation and process monitoring tool.

cross-section-273

With our pioneering efforts in the early 90’s, Crimp Force Monitors have become a core technology which is now widely used in wire processing. Required by Automotive and White Goods manufacturers.

Advances in electronics, software and wireless technology have made networking of production equipment in-expensive. And very powerful. Now you can retrieve real time data from any process, including crimping machines, ultrasonic welders, rotary assembly boards. To monitor and report machine up and down time, defects, production quantity to name few.

WPS: Do you see other industries following the Automotive lead and adopting new crimp quality technology

CL: White Goods is one industry that has seen significant improvement in the quality of their wiring systems due to them embracing new processing, harness designs and monitoring systems.

WPS: What do you see as an emerging technology in crimp technology.

CL: Crimp Cameras are now being mounted on automatic processing machines. What was not feasible ten years ago is now possible with the advanced electronics, software and camera technology. In the case of wire processing, high speed machines require ultra fast feedback to address defects such as high insulation, brush errors and deformed insulation crimp wings. We are on the cutting edge of this camera technology.

Thank you for your time today Chris. WPS values the association we have built up over the past two decades and anticipate helping our customers adopt new and emerging technology in wire. Thank you for your support.

 

 

Counting The Cost of Quality: The Cost of Action 

Every decision has a cost.

Large or small there is a cost to every decision. Of course there is a sliding scale of the size of a decision and it’s relationship to the overall implications to the organization. Some costs are economic and some are not.  Deciding on a bathroom cleaner or brand of pencil to stock have fewer implications than a capital purchase or facility relocation.

This the first of three articles focused focused on quality and considerations when making improvements to an existing system or completely starting from scratch. Also the costs associated with these actions that have far reaching implications to product quality within a manufacturing environment. In this post we are focusing on the cost of action.

Here are a few point for consideration.

Management acts on quality improvement but there is usually a trigger. Triggers that cause management to act are either external or strategic. External triggers often come from customers who require improvement in quality either due to a complaint or issue. They are also driven by the customer’s desire to focus on a specific industry sector that demands higher quality standards. Strategic triggers are based on the company moving into a new industry sector which (like the customer) demands an enhanced quality or documentation of quality. Regardless of the trigger it all boils down to one thing: economics. Losing a key account or losing out on a new opportunity to grow the business in a new direction can greatly affect revenue which can affect the business partly in the short term but mainly in the long term.

Management not only needs to be fully committed to a new quality system, they need to be the champions of it. Often it is management that has a neutral or “wait and see” attitude. This can be damaging to the success of implementing a new quality system. Or the efforts to make permanent the change in culture. Employees are watching. When management waivers, employees often follow.

We will expand on the potential negative affects in part two: The Cost of Inaction.

Commitment includes attention to the following areas:

Employees need to be fully supported. In the form of solid two communication between management and employees. They need to understand the reasons behind the change or initiative. When communication breaks down so does the trust.

Employees also need appropriate training. The company needs to provide the funding for training (and re-training) for all workers directly (and indirectly) involved in quality.

Resources are critical to the success. These include measurement and in process monitoring tools for validating and monitoring production. Also access to applicable quality standards for your industry. These tools provide data necessary to feed back to management on the current state of the quality system.  And levels of improvement over time. One important point. Providing new measurement tools is an important first step but often they uncover the current state of the quality system. They do not improve it. Training in conjunction with the above tools can provide the information needed to make the changes needed to drive quality improvements. But looping back to management’s commitment, they need to drive the changes needed (and the speed of change) and support the organization as a whole.

Capital Costs are important over the life of a quality improvement initiative.  As information starts flowing on the current capability of the production system, it may become evident that production equipment over the long term is not capable of repeatable results of a higher quality level. Replacement production equipment or major upgrades to existing equipment will be necessary.

In summary, making a decision to improve quality comes at a cost. In the attitude of management and employees, a commitment to invest in the resources and the capital needed to make an improvement in product quality. There is also a cost of inaction which we will cover in part two. And the benefits? Part three will uncover the reasons why sticking it out to the end will be critical to the company’s survival in rapidly changing business conditions.

Crimp Force Monitors Do Not Solve Your Crimping Problems

There I said it. Let me repeat:

Crimp Force Monitors Do Not Solve your Quality Problems.

Now that it’s out there let’s back up a little. First of all, let me be crystal clear. Crimp Force Monitors (CFM) are an essential tool of a quality system for any company that is serious about providing quality wire assemblies. The ability to monitor your process with a crimp monitor is extremely valuable for a number of reasons which we will unpack in this article. But let’s put things into their proper perspective.

First of all, a crimp process that has excess variation exists that way with or without a CFM. A CFM does not resolve crimp problems but will provide plenty of notification to the operator of this condition. In the form of CFM alarms. It is what is done from this point that is critical.  If the tolerance is opened up to silence the alarms or (worse) the monitor is turned off, then the true value of the CFM is lost.

Second, a CFM works best with a process that is in control and shows little piece to piece variation. This provides sufficient room for detecting small defects in the crimp process. Excess variation adds “noise” to the detection process and a CFM will have a harder time in determining a defect or just normal process variation.

The video below is from the 2016 Electrical Wire Processing Technology Expo and the seminar co-sponsored by C&S Technologies and Applitek Technologies: Do You Really Know Your Crimp Process where we discuss the CFM Cycle, a scenario played out countless times as new CFM Technology is introduced.

So what value is a CFM in the crimping process?

First, real time monitoring is 100% effective in measuring the crimp process. Visual inspection is only 80% effective over time and 100% manual inspection is not practical. It also answers the question: “what is happening between the first off article inspection and spot in process inspection”.

Second, as a process analysis tool, a CFM is effective in improving the crimp process over time. This is done by analyzing the five elements of a terminal crimp. And improving each process. The direct effect is a process in greater control and able to detect smaller variation.

Finally, as part of an integrated network of processing machines, the CFM can feed valuable production quality data into a central database for archival and analysis. Also provide a level of production quality approval by preventing access to production equipment until quality measurements are within allowable parameters.

So the question is “Do you need a CFM equipped facility?” Consider the following and judge for yourself.

  • Pull test and crimp height measurements are a static and one-time check of quality parameters. As important as they are to production quality, they are not sufficient in of themselves. A CFM is one example of dynamic quality measurement in real time. Press Analysis is another example of dynamic measurement.
  • CFM’s remove subjective judgement of good or bad crimps from employees.
  • CFM’s monitor the whole crimp process and the associated elements.
  • Without crimp monitors, the risk of defective wire harnesses increases and the cost of rework (not to mention product liability) will exceed the initial investment of crimp monitor technology by a large margin. “It hasn’t happened to us so far” you may say. “We have crimped millions of parts over the years with no problem” is another one. The laws of probability will eventually catch up without effective dynamic crimp monitoring. Why take the risk?

Do not take the risk! Our Global Technology Partner: Crimping and Stamping Technologies is a global authority in the terminal crimp process. Connect Your Way to WPS for an analysis of your crimp quality requirements.

Static vs Dynamic Measurement of Crimp Elements

Quality measurement has been an essential part of process validation and control for manufacturing for centuries. Engineering a product design with critical dimensions needs to be validated by quality measurements during the production cycle.

In the early 20th century, statistical analysis of quality was introduced into the quality process of validating manufactured goods and adopted in a number of industries. Automobile production embraced statistical analysis as a result of W Edwards Deming’s influence as the founding president of the American Society for Quality Control.

Today in many industries, a mix of static (one time) and dynamic measurements are used to validate process measurement. In the Wire Process Industry there are a number of measurement tools used which include pull testers, crimp height micrometers and dynamic validation tools such as crimp force monitors. In Wire Processing, dynamic measurement tools are being adopted, aided by the inclusion of them in new processing equipment. But in some respects, a general awareness of the critical nature of dynamic always on quality measurement tools is lacking.

For example, crimp height measurement. Some companies still use the crimp height as a static first off quality measurement and then not measure another part through the balance of the production run.

Or Press Calibration. Calibrating a crimp press with a shut height gauge to the proper shut height without measuring shut height or press force repeat-ability.

These are mistakes. A single part only assures you that that part (or process) is within production tolerances. And does not take into account variation from all input elements in a crimp process.

Dynamic measurement tools provide a piece by piece indication of process capability and detection of crimp errors. Dynamic capability studies of press shut height and crimp force provide valuable information on a press’ ability to supply repeatable crimp force.

Press Analyzer

Here is a clip from our seminar at the 2016 Electrical Wire Processing Technology Expo. This clip illustrates the value of dynamic press analysis.

Static measurements such as crimp height and pull test are not obsolete in today’s production environment. In fact they are valuable first off process validation tools but need to be supported by dynamic measurement from crimp force monitors and crimp camera systems.

So what are the implications of not dynamically measuring crimp elements in real time?

  • Rework cost from defective product
  • Related costs and penalties from customers
  • Lower customer confidence
  • Maintenance and Quality resources not deployed on priority issues because objective information is not available.

Flip these around and you can see the benefit to your organization. So you say these problems have not occurred to our company? Perhaps not in the past but there is always a real risk of these problems coming up in the future.  And without objective analysis, you just don’t know.

Act now. Let us provide you with the tools and services you need to get a start on measuring and improving your crimp quality. Connect Your Way to the WireProcess Global Community.

 

Terminal Cross Sectioning: Taking a Peak Inside

Terminal Cross Sectioning is a quality validation technique that is not new to Wire Processing. The use of cross sectioning has broadened over the past few years and cross section systems are now appearing outside of the quality lab and on the factory floor. This trend is expected to continue in the coming years. Cross section labs are expected to be as commonplace as a pull tester in most processing facilities.

In the past, quality tests of a terminal crimp were performed by only a pull tester and being a destructive test, it was a first off and spot in process inspection.  But it certainly did not take into account the inherent process variation of the crimp process itself. Later on as electrical performance demands increased, it was necessary to improve the quality inspection processes. At the same time, crimp design advanced and no longer was just pull test sufficient. Enter crimp compression.  Crimp compression standards were a result of studies into crimping and it was determined that a predictable percentage of crimp compression was needed to assure optimal electrical performance. Crimp Height is based on optimum compression of the wire during the crimp process.

With Cross Section analysis, we can now peak inside the crimp. This cross section analysis provides us with a great amount of detail into not only the materials (wire and terminals), but how they are crimped together.  Information that is used for documentation and archival purposes.  An important aspect of cross section analysis is process improvement. Some of the measurements available from cross sectioning a crimp include:

  • Crimp Height
  • Crimp Width
  • Crimp Compression
  • Crimp Height to Crimp Width ratio
  • Capability Studies including crimp height.

Process Improvement is a necessary component of any company who wishes to reduce their processing costs (material waste and processing time) as well as improving overall productivity. Cross Section analysis can be a valuable tool in process improvement. For example, crimp monitor alarms. Crimp monitors signal an alarm when an element of crimp quality causes excess variation.  Often the suspect parts appear normal and acceptable. Production continues. Later on another alarm occurs.  Same condition.  Parameters are opened up and production continues without alarms. But the underlying problem still exists. Once this cycle starts, the monitoring system becomes less sensitive and at some point only gross errors can be detected.  And the risk of accepting defective parts also increases.

Cross Sectioning a crimp offers one way of detecting an issue that could be quickly assessed and a resolution put in place. See the illustrations below.

cross section (110)

Crimp wings touching crimp floor.

cross section (130)

Uncompressed strands and uneven strand distribution.

These are two examples of conditions which can cause variation which a crimp monitor interprets as a defect. Which can affect electrical performance.

Embracing Cross Section Analysis as a critical validation tool is important for companies in the future. Costs have come down to the point where most companies can justify a base system for plant deployment. The WPS Cross Section Service is another way to get your analysis completed while working out the deployment of system for internal use.
