My 144 pin land pattern is pretty close (100mils) but we are mounting the board into a very flat structure (no bowing) I can't imagine the compression of the board material could affect gull-wing style lead connections (maybe BGA?) but I don't know... thanks, Jack ______________________________________________________________________ This email has been scanned by the Symantec Email Security.cloud service.
