Where Is The Etching Tank ??? | |
Stage 1
I need to make 3 controller boards and 1 interface board.
Had some spare photo-resist board so after printing the artwork on a HP laserjet printer to clear film It was time to hunt out the UV exposure box.
Some of the pads are not as thick as I would like, especially as they need to be hand drilled.
Photoresist was not too bad so I will continue. |
