This blog will contain some cable & wire facts. In this episode we discuss the Crimp Height Testing. Nowadays there are more and more companies that, in addition to their core business, also provide cable and wire harnesses services. Most of them started making wire and cable harnesses because of the costs. They think that, when you have a crimp tool, you can start making your own cable and/or wire harness. But what they don’t think of, are all the quality test you have to perform to make sure your product is reliable. These tests are part of the process to provide objective evidence to the customers.
JUST SKIP THE TEST….
Due to costs, a lot of companies will skip these tests because they will take additional time. Time is money and the time to market (TTM) should be as short as possible. So what they really are telling is that time (and money) is more important then quality.
Most of the test equipment will cost a lot of money and if cable and wire harnesses are not your core business, we will asome that you don’t spent additional money to buy all the test equipment you need! Right?
So, if you take cable and wire harnesses seriously, we assume that you have at least a Crimp Height tester and /or Pull Force Tester and of course calibrated tools and equipment.
All crimp tools shall not be used for longer than 30 days between verification testing except when based on historical data.
Crimp Height Testing
And did you know that you must perform Crimp Height Testing for class 1 and 2 products if you don’t perform Pull Force Testing?
And that Crimp Height Testing is required for each new setup and again after every __parts, and/or every shift(s) and/or after __working days?
Crimp Height Testing is very important. It will verifies that the terminal crimp height is within the terminal supplier’s specification. Each crimp terminal and conductor combination will have unique crimp height criteria. This is an optional test for all Product Classes if pull force testing is implemented. You should document the values after each Crimp Height Test. This will be objective evidence that your crimp process is reliable!
It is critical to ensure that crimp heigh measurements are taken correctly! Crimp height measurements tools have a flat blade on one side and a pointed on the other side. In another episode of cable and wire facts we will show you step by step, how you should perform a correct Crimp Height Test.
