I need some information on alternative solder masks to be used with no-clean flux. 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!!!
