I decided to make already crazy budget monster Astrolux EC06 even crazier by modifying it to use SFN55.2 leds. So I need board for 7070 leds and there being none, I made one myself from 0.5mm copper sheet.
1st. Phase:Cut templates
2nd. Phase: Test fit filed down pcb’s. Still some more filing to do.
3rd. Phase: Solder everything together on a hot plate. Beforehand reflector holes were reamed to 9mm. Reflector was then used to hold leds in correct orientation.
4th. Phase: Wire management. Not the easiest one.
5th. Phase: First full power test with Molicel P42A’s. Wires desoldered themself from driver because of heat. It was few pops and light went off.
6th. Phase: Cleaned the solder pads and added higher melting temperature solder. Everything back together and it works. Hasn’t desoldered again. Very bright and also has hotspot instead of pure flood.
