Address, It's been a few months, but I'm back on the NET Cowboys and Cowgirls. You previously knew me as John Gulley at Hitachi Computer Products Division in Norman, OK. I am know with Compuroute Inc. in the BIG D of USA or Texas. Enough of the intro..... Does anyone have experience in desmearing, etchbacking and eletroless plating SPEEDBOARD (PTFE-Teflon) materials. We have been using SPEEDBOARD for approximately a year and have had good success through our processes. Recently we have encountered some process issues that are effecting overall quality. Anyone's assistance on this matter is greatly appreciated. Regards, Thomas John Gulley Process Engineer p.s. *In know way are we a competitor to PCB shops in the industry.
