Hello,
I have a question about the bow and twist of
printed circuit boards.
I have had some boards with bow and twist. As a
result of shearing the prepregs in the wrong direction.
Now I have double sided boards with the same
problem ( bow and twist about 3% ). I have seen that the b&t is on all
the boards that have V-cut/scoring on them. These boards are about 400mm long
and have scoring in the length of the panel.
Can this bow and twist be a result of the scoring
of the board?
If so what can i do to prevent is from
happening.
Best regards,
Gerard
