I have a BGA with 541 balls at .75 pitch and .4 pad which makes the via 'microvia' add to that necking down 6mil to 4mil traces and a 2X2" board is over $100.
Does anyone know of a PCB shop that can do microvia and 4mil without breaking the bank?
It must be possible since I can buy boards with this (i.MX7D) on it and a ton of other parts for $60.00

I have used this company for my prototype boards for many years. According to their webpage they can handle the 4 mil traces. and partial down to 3 mil
