UV LED MOSFET driver board for custom PCB light etching

This is a a MOSFET driver board that can source 4x 1A of current to 4 separate arrays of ultraviolet LEDs. The purpose of this project is to design a UV exposure box that can develop photoreactive printed circuit boards. I didn’t have a large bench power supply that can supply 4A of current to […]

UV Exposure PCB Timer With PIC16F877A_Update

Here is an UV Exposure PCB Timer. This timer working only for an Hour, to control an UV TL Light inside the box to exposure the PCB. If you want to made your self PCB or do for masking (solder mask) this is you need. source
