Technetters,
IPC-6012 indicates that the allowable bow and twist of PCB is .75% for SMT
and 1.5% for others.
I have a PCB that is exhibits bow and twisting and I want to make sure that
it is inside of the acceptable parameters.
The board size is 10.98" x 6.81", so the allowable bow and twist would be:
.75%- 0.561"
1.5%- 1.122"
Are my calculations/assumptions correct?
Any and all advise would be truly appreciated.
Regards,
