Hello All-

For many years we have specified matte finish LPI soldermask. Have a
supplier asking us to switch to gloss or semi-gloss to avoid 'solder smear'
issues.

Any input as to the pros and cons of each would be appreciated.

I think I remember issues finding fiducials with glossy mask but I might
just be making that up, and all the equipment has changed since then
anyway.....

Thanks in advance,
-Chris
