How PHILIFAST Control The Quality of PCB Quality
1，Process review
1.1 Confirm customer special requirements and product special characteristics (the mount-ability and temperature resistance of structural special-shaped parts)
1.2 Confirm whether the BOM and PCB manufacturing data are up to date, whether there are any items to be confirmed, etc.
1.3 Assess whether the PCB shape (joint board structure) process can be mass-produced
1.4 Manufacturability evaluation of special pad process of PCB board (gold, OSP, spray tin, SMD, NSMD, etc.)
1.5 Design different opening methods and choose different mesh steel sheets for different process PCBs
1.6 Verification and evaluation of the suitability of special-shaped parts and other special parts with PCB pads
2, Incoming inspection（IQC）
Inspection purpose: to prevent poor manufacturing process due to poor materials and unqualified quality of refurbished materials on the line to prevent aging loss
3, SPI Solder Paste Inspection
Inspection purpose: find the defective solder paste printing in advance to avoid flowing into the next process
4, AOI Inspection
Inspection purpose: to check whether the produced products have errors, omissions, and bad materials flowing out of the next process
5, SMT First Article Inspection
Test purpose: to confirm the correctness of the production line placement process, to ensure that the parameters of each RC component are within the standard range
6, IPQC product inspection
Inspection purpose: to conduct random inspections of all production processes and whether they are consistent with the work instructions
7, Visual inspection
Inspection purpose: according to the IPC610D standard, inspect the surface-mounted PCBA that has been soldered for errors, omissions, and virtual connections.
8, X-Ray Welding inspection
Inspection purpose: to inspect the solder joints of the original invisible to the naked eye to ensure the reliability of each solder ball of the BGA
9, QC Manual inspection
According to the standard IPC-610 inspection standard, the finished boards are inspected, and 99.98% of good products are guaranteed to be shipped.
10, Automatic splitting machine
The fully automatic splitting machine for milling cutter testing is accurate and fast. Automatically take typesetting to avoid manual contact
11.QA Shipment inspection
Strictly inspect before shipment and scan the code for verification to prevent unqualified products from being shipped
