What is the appearance of PCBA finished product inspection standards

1. Check whether all the components on the board are consistent with the BOM. There are no adverse conditions such as low material or wrong components.                  

2, the polarity of the tiling element is correct.

3, the appearance of components is complete,without damage, battery insulation can not be damaged, dirty, painted.

4, check whether the solder joints tip, false welding, false welding, trachoma, warping, short circuit, welding, solder and other bad situation.

5, IC, PCB, triode, BGA, QFN need to check the material screen printing is correct.

6. All DIP components need to be 100% tin-through, and the front pad tin solder needs to wrap the leads.
