I am looking for anyone who performs Hot Air Solder Leveling in the Eastern
Mass area.
Beyond that I am interested in hearing from anyone who has experience in
soldering to surfaces that have had mask removed using a CO2 laser powered
mask removal process. Post mask removal, there remains a light adhesive
coating on the copper surface that resists tinning. We are exploring
various methods of cleaning this residue and having mixed results. These
boards are multi layer boards with surface mount population.
Any help you can offer on either topic would be greatly apprecieated.
Thanks,
Charley
