Hello,
Our company largest DS PCB manufacturer in Malaysia.We are
encountering
the soldermask skip problem.I give below the parameters used.
M/C Burkle Curtain coater
Ink Peters GL2469sm
Viscosity 60to65
Beltspeed 78m/mim
web weight 6.4to 6.8gms/600sqcm
We use pattern plating process and plating thickness 40to 60 microns.
The Sm skip is random and happens near closely spaced tracks(most of
the times).
I Shall be highly grateful if anyone can give info to minimise the
sm skip problem.
Thanks
