Re: Soldermask Over Via
Hi,
When the Pcb are in deisgn & developing process ,then the purpose of unmasking the Vias is for testing the Pcbs,before final product release.
As cyberrat says,why one need to go for wave soldering while the PCBS are still in the design process?please explain.
And most of the company usually unmask the via for testing purpose,since they probe it into the via and test the functionality,they can't always have test point for every functional blocks though...?
In the previous mail,regarding the Bga masking on top side,we can also use Via Filler.....
