Don:
Don't throw the baby out with the bath water. Before
you decide to go with glossy mask, here are some things to
ponder.
1. Glossy mask tends to attract solder balls more frequently
during assembly. This is because of the higher surface
tension. Surface tension tends to be broken up by the matte
masks.
2. Inspectors prefer matte soldermasks over glossy. The
glare thrown off by glossy masks can really get to you after
hours of looking at boards.
Perhaps for these two reasons, the majority of my customers
specify a matte soldermask if anything. I would suspect
that glossy masks can contaminate as well as the matte
versions, so your company's decision based on this one bad
experience might cause problems further on down the line.
Good luck!
