All went well with the bare PCBs. The laser tech was able to program the pattern and dial in settings for power and speed that yielded acceptable (at least visually) results. But, I have to PCBs that are partially assembled with components that I also need to have laser removal of soldermask. I can overcome the fixturing concerns, but does anyone know if I should be concerned about ESD while the part is being processed? Is the CO2 laser a source of static?

I am new to the laser process and operation, but have experienced technicians to rely upon. Any general or specific advice in terms of intensities, speed, or other factors?
