Does the fixture need to be equipped with a good product sample?

necessary.

It is necessary, when the jig is manufactured and debugged, good samples are needed for program debugging. For daily maintenance, after switching the product jig each time, use a good product sample to test it first, which can quickly prove that the jig is installed in place and the equipment has reached the state of normal production testing. In the process of production testing, if there are consecutive bad batches, you can also use the good product sample to test again, quickly prove and identify the problem of the product under test or the fixture machine.
