Double Sided Microcontroller Controlled PCB Exposure Box

This Double Sided Microcontroller Controlled PCB Exposure Box uses a PIC 16f268 to time the exposure LEDs on for the entered exposure duration. You can select if you are doing a single sided or double sided board, then you set the exposure time you need. After this you just sit back and relax while your board is getting perfectly exposed. We have seen some exposure boxes before including this UV LED exposure box project but I must say I prefer the controller on this one.

“If I had to expose a double sided pcb with my previous exposure box, I needed to turn it on twice. (1 time for the top, and 1 time for the bottom) To solve this problem it was time to build a new version. This new version will do the 2 side’s at once.”
