Here is an outline of our 16-point quality assurance program:
Tooling and DFM Assistance
1.We use DFM Software to review and 100% check customer’s Gerber files to ensure manufacturability.
2.Check plots are sent to customers for approval prior to production.
Optical Inspection
3.First Article Inspection is carried out in every process to ensure IPC-A-600 and customer specifications are met.
4.Complete Inspection under microscope of all panels after PTH (Plating Through Holes) to confirm there are no void holes, or any debris.
5.Complete Inspection under microscope of all panels after film developing to confirm there are no scratches or any over /under-developing.
6.Complete Inspection of all panels under microscope after film stripping to confirm there are no film chips remaining on panels.
7.After Etching, inspect under microscope check to confirm no under /over etching has occurred and measurement of trace width.
Automated Optical and Inspection – AOI
8.An AOI (Automated Optical Inspection) is preformed after Tin stripping process, to confirm that there are no shorts or circuitry openings.
9.Complete Inspection of all panels after LPI (Liquid Photo Imaging) to ensure that there is no solder mask remaining on the pads.
10.Complete Inspection of all panels after finishing process (HASL, Lead free HASL, ENIG, or Silver Immersion) to confirm no mask on pads.
11.Complete Inspection of all panels after IDENT process to ensure cleanliness of pads before final baking process.
12.Complete Inspection after routing process to ensure customer specifications are met with their documentation.
Test and Measurement
13.E-Test: Electrical Testing is preformed before solder mask to ensure integrity of circuit (no shorts or open circuits) and final 100% E-test of all boards prior to shipping.
14.Measurement: After complete inspection of all finished boards to make sure that all customers’ specifications are met and all IPC-A-610 Standards such as board dimensions, hole and slot sizes, board thickness, and board finish are met.
15.Micro -sectioning: To ensure that there is no internal failure, we carry our cross section of the final boards, make cross-section coupon, inspect and measure internal structure and prepare cross section report.
Quality Records
16.Upon request, we provide quality records such as First Article Report, Impedance Record, E-Test Report, Cross Section Report, Final Inspection Report, CMI Report, CoC Certificates, RoHS certificate, REACH / Conflict Mineral Compliance certificates to the customer.
