(1)Client test process were found to have features characteristic of bad repair, found the phenomenon of partial hole, as of 11 / 3, accumulative total out of 500 characteristics of bad bad machine
(2)Client inventory and the factory inventory of all exit, with high foot mirror measurement selection, hole ring is less than 2mil direct disposal
(3)Division I drilling process migration capacity of + 3mil, outer line offset degree control for the 3mil, when a hole and outer lines respectively to both sides of the maximum offset, offset degree of 6mil, and this location hole ring of ring single edge just for 6mil. So when drilling and outer lines respectively to both sides of offset, can appear the serious hole deviation phenomenon, before production without special control the position
(4)Client inventory and the factory inventory of all exit, with high foot mirror measurement selection, hole ring is less than 2mil direct disposal. Will control the drawings and inspection standards for dry film, IPQC, FQC, OQC, inspection of the position of the focus of inspection, the hole ring is less than 2mil from scrap processing
(5)
Customers will reflect the hole deviation adverse inspection standard paste in the borehole, dry film, a test, OQC test platform, make inspection personnel to further understand the customers reflect the adverse, found a hole ring is less than 2mil removed, to avoid adverse once again into the client
(6)
At present, the client used on-line to have screened PCB, follow up client yield. The next batch of orders production tracking factory production yield and client on-line status
