  For the pcb manufacturing, we have the strictest system to control this pcb quality. the pcb from the first process" Board Cutting” to" PCB Finished" .  Each process of quality output has been well controlled.
PCB in process

Each process that we have set up the IPQC inspection station to specially inspects and controls this quality.It can ensure this process of pcb output is fully qualified to next process.
For example: solder mask IPQC inspection station.
****
Our IPQC is doing the inspection on solder mask which is basing on the IPC standard or industrial standard.
Its inspection items:
Solder mask opening compliance;
Solder mask type using compliance

Solder mask appearance and adhesion strength etcs
Electric function test

All pcb we done 100% electric function test, to make sure there is no any failure pcb issue.
For the pcb function test we adopted the AOI and E-Test inspection..

****To use the AOI to scan inspection on the precision circuit pattern and detect any failure pcb.
To use the E-Test as screening for any open/short circuit problem on plating through hole of pcb.and eliminate any failure pcb.
Reliability test
Each p/n for pre-shipment of pcb, we defined that it has to do solderability and thermal shock test as verification, whatever surface finished it is,like ENIG/Gold flash/OSP/HALetcs.we requested the solderability and heat-resistant of performance are full compliance with IPC standard or customer requirement..
****
Do the solderability test that is to verify the soldering pad whether is wetting or dewetting.

Do the thermal shock test that is to verify the pcb of heat-resistant of performance on solder mask/Laminate and plating through hole..

All test method that is follow IPC-TM-650.
Final inspection
All pcb pre-shipment, we do 100% vision inspection or magnifier inspection on pcb appearance, to eliminate any defective pcb, as well as we do the engineering inspection is according to customer gerber file or drawing as final confirmation lest wrong design of pcb issue……
****

Do 100% inspection on PCB appearance refers to IPC-600G
Engineering inspection are contain:
Dimension&holes drawing compliance
Circuit pattern compliance
Solder mask opening or legend mark compliance
All these item verificationis based on the customer original gerber file or
drawing to one by one carefully check by our shipment QA.That is purpose to make sure the shipment of pcb is fully met customer spec..
