Q:How to guarantee the quality of products?

For PCB, we will use Flying Probe Test amchine,E-test machine,2D Measure Machine,Copper Foil Tension Test Machine,Surface Finishing Thickness Measuring Machine,Long Arm Thickness Measuring Machine etc.

For PCBA,we need you to offer us a method or test fixture for the function test.Before that,our inspectors will use microscope and X-Ray to check the IC footwelding or bad solder etc.
