Hello there, an engineer friend of mine suggested asking this question to
this address for advise.
I have some separation of BGA contact from PCBs, the pad size is 20 mil,
the balls are 30 mil, the pitch is 50 mils. the board is Fr-4 , 0.062 ". 4
layer
is this configuration acceptable or what changes to the pad could be made
to improve solderability?
thanks in advance,
