Subject: [TN] Best surface finish for BGA


The question has been raised here, what is the best gold finish for high
density BGA pads - Immersion gold or gold flashing?   Keep in mind it
needs to be an RoHS process.  Or is there another finish more suitable.
It has come up as a result of our pcb contractor having difficulty with
some BGA's taking.
 
Regards,
 
 
Bernie Greaves
