PCB Assembly test system:
1. Visual inspection after SMD Process
Each SMT lines have one QC person to check the SMD solder quality after assembly.This step is visual inspection, here to verify if any parts loss or incorrect parts are used via checking the BOM list.
2. AOI Testing(X-ray Testing for BGA package)
Automatic Optical Measuring Instrument VCTAB486 Positioning accuracy<0.15mm
Moving Speed:700mm/s
Measurable minimum element:0201
Measurable Pcb range:25*25mm-340*480mm
As a primary testing technique in PCB assembly, AOI applies to fast and accurate inspection of errors or defects occurring in PCB assembly process so that high quality of PCB assemblies can be ensured with no defects after their leaving assembly line. AOI can be applied both to bare PCBs and PCB assembly. At XD, however, it is mainly applied to inspect SMT (Surface Mount Technology) assembly line and for testing of bare circuit boards, bed of nail and flying probe are used instead.
3. Free Function Testing.
For 100% make sure the quality, we do functional test for customers free of charge, provide free testing jig and free program burning.The testing method is usually offered by customers; but if customers couldn’t provide it, our engineer will design a test method for the board as well.
4. Final visual inspection
