I tried making a pcb using Direct Etch's TTS. The problem I ran into was that the entire layout didn't transfer to the copper.
I printed the layout to the TTS paper back in November and for various reasons wasn't able to try making the board till yesturday. Could that have been the problem? We used a scrub sponge with dishwashing soap for the copper. Just prior to that the board was cleaned with acitone. The board is a two sided board so we drilled two pin holes to locate both sides of the layout. We then used an iron for about 15 sec on each side to get the TTS paper to stick prior to sending the copper and TTS paper through the laminator. After the board came out of the laminator we soaked it in water for a little over a minute and when the TTS paper came free of the copper a portion of the layout wasn't adhered to the copper. Can anyone see where we messed up? Does anyone have any suggestions? Thanks
