Exactly. Also consider how customers are begining to dabble in LF and want to use the same FABS for concurrent builds. The don't want to add or modify any PCB artwork and pay for NRE changes. And they don't want to keep two part numbers for the sa

measure the board thickness before coat by a screw gauge, and then after, when the coating has fully cured. this works well for a single side coat. once your wet to dry thickness is down, you can spray to a particular thickness wet and be reasonably

There's a ton of em'. We used the one from Paul N. Gardner Company, part # WF-CCD. They cost 0.95 each, so if someone decides the gage looks better in their garage, it's not that big of a deal. We set up a program that puts down 4 stokes on a test

Hi Jimmy, We use flat belt exit conveyors. They are set-up to collect the boards and set off an alarm when the belt is full. This allows the boards to come out, but you don't have to pay someone to stand there and catch each board. Also eliminate
