UV LEDs PCB EXPOSURE BOX with ATMega328 PART IV

Ένα φορητό σύστημα εκφώτησης PCB με UV LEDs και πραγματική σάρωση, με ρύθμιση ταχύτητας κεφαλής σάρωσης (1-10cm/min), μεγέθους πλακέτας (1-30cm) και ισχύος φωτεινότητας (5-100%). Δυνατότητα αυτόματης εκτέλεσης προγράμματος ή κατά βούληση εκκίνηση και σταμάτημα. Φτιαγμένο απο έναν παλιό scanner EPSON CX8400 και τα ηλεκτρονικά σε διάτρητη πλακέτα. This is a portable PCB exposure system with […]

pcb uv exposure unit

contains 3 pairs of pc blacklight lamps and a custom timer with lamp compination selection and pre-heating stage for 2 minutes. It uses a pic 16f628 programmed in C and an ready made power supply giving 12V for the lamps and 5V for the microcontroler board. The casing is made out of an old computer […]

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
