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 […]

VioLED – A UV LED double-sided PCB Exposure Box

This is the prototype of the design of a double-sided PCB exposure box designed by Freyja Yeatman. It was made for the Mechatronics 2 course at Reykjavík University in the spring of 2016. The full-size box has yet to be made but this prototype works for small 50x70mm double-sided circuits. source

DIY Circuit Board Exposure Box Using UV LED’s

Exposure board almost done. Intend on using along side an Arduino Nano to be used as a timer and to control light intensity. In the end will have an additional light board for exposing 2 layer PCB’s source

UV exposure box using LED and arduino. DIY.

This is the project 80% done. A UV exposure box for PCB production. The processing unit used is the teensy, which is arduino capable. 124 UV LED’s are used, and a salvaged synaptics touchpad from a old laptop. source
