Hi Joe - Your statement......." type AR or type UR does not coat the BGA
solder balls/solder connections located under the BGA so you are violating
the acceptability requirements in IPC-A-610" has me some confused. What
IPC-A-610 requirement is violated?

Vered,

I would start with IPC-A-610 and J-STD-001 documents. One item that is over
looked is that spraying a board with for example type AR or type UR does
not
coat the BGA solder balls/solder connections located under the BGA so you
are violating the acceptability requirements in IPC-A-610!

Good luck,
- Joe
