I've been tasked with increasing the CCA throughput in our Conformal Coating workcenter. My first approach will be to look into a more *automated* approach for the masking process. We currently use a manual method of using masking tape prior to con

On the money as usual! (Your subtle approach is something to behold. Much like my approach, which has gotten me into more grief over the years than I should be allowed to have.) Boca
