Do you refer to "permanent" solder mask (ie. applied by PWB vendor) or temporary solder masks (that you apply and either "wash off" or manually remove)? I can go into our experiences if you want to call or email me directly.

Protecting tooling holes as the CCAs are processed across the wave solder machine is the concern. We are considering Kester 973 VOC flux and Kester 951 no-clean flux. We solder in panels, half panels, and single boards. I am expecting the machine to automatically control wave height to prevent flooding, etc. Could I please get some feedback on the mask issue since I will be doing some tests on some machines in the immediate future. Thanks in advance!!!
