Quality Control Process
1. Complete accuracy analysis of customer design (Computer Aided
Design)
2. Troubleshooting checklist, Send engineering questions if any.
3. Check plot ( prior approval by customer, if production gerber is
requested)
4. Inspection of “First Article Panel” after drilling procedure to
ensure IPC-A-600 and customer specifications.
5. Complete Inspection of ALL panels after PTH (Plating Through
Holes) to confirm there are no void holes, or any debris.
6. Complete Inspection of ALL panels after film developing to
confirm there are no scratches or any under developing.
7. Complete Inspection of ALL panels after film stripping to
confirm there are no film chips remaining on panels.
8. After Etching, check to confirm no under/over etching has
occurred.
9. Do Cross-Section analysis to confirm quality and proper
distribution of copper plating.
10. An AOI (Automated Optical Inspection) is preformed after Tin
stripping process, to confirm that there are no shorts or circuitry
openings.
11. Complete Inspection of ALL panels after LPI (Liquid Photo
Imaging) to ensure that there is no solder mask remaining on the
pads.
12. Complete Inspection of ALL panels after finishing process
(HASL, Flash Gold, ENIG, or Silver Immersion) to confirm no mask on
pads.
13. Complete Inspection of ALL panels after IDENT process to ensure
cleanliness of pads before final baking process.
14. Complete Inspection after routing process to ensure customer
specifications.
15. Electrical Testing is preformed to ensure integrity of circuit
(no shorts or open circuits). QC & A (Quality Control & Assurance).
16. Complete inspection of all finished boards to make sure that
all customers’ specifications are met and all IPC-A-600 Standards such as board dimensions, hole and slot sizes, board thickness, and
board finish are met.
