3.2 The quality assurance department PQC strictly conducts inspections in accordance with this standard

3.3 Each relevant department is the supporting department for this document

4.0 Equipment/Tools

Microscope, pull-out force gauge, caliper

5.0 Standard Content

5.1 Before the terminal machine is turned on every day, the inspector first uses a microscope to inspect the appearance of the terminals, and first determines whether there are any defects such as core wire indentation, adhesive pressure, punctured rubber, terminal deformation, and terminal damage

5.2 Use a caliper to measure the conductor height, insulation height, and terminal pressing width of the terminal (the maximum width at the pressing core and adhesive)

5.3 Final test of terminal pulling force

5.4 The standard for testing the terminal pull-out force positioning part is: a vertical 90 degree angle, and the fixture clamps the part of the terminal that does not have a core wire

5.5 Test the terminal pulling force, conductor height, insulation skin height, and pressing width every half an hour

Test above 5.6, 2EA each time

If any item is found to exceed the standard during testing, hold the product within one hour and hand it over to quality assurance and engineering personnel for handling. Request the repairman to adjust the machine. And retest after adjustment to determine the adjustment effect
