We've think that with seen solder shorts under BGAs after wave soldering the boards. In addition, it seems to be related to a certain soldermask configuration over the topside BGA vias.. THere is one vendor,A, that is applying soldermask after HASL,

The biggest problem I am having is the X-Ray and ICT could not detect this shorts.ICT could not detect because onboard measurement shows Zero even without the Hair line shorts.With Hairline there is no difference in the impedance value for ICT to fai

Your statement is interesting, but not necessarily correct. Are shorts in the same location? Is it one short or multiple? Are there any vias in the BGA pads on the PCB? Is part MSD and handled as ESD?
