SMD soldering using the sun. it works astonishingly well. the trick is to de-focus the spot and light up the whole PCB. first we failed by heating the metal plate underneath with a highly focused spot. but that led to accidentally burnt PCB spots at corners and didn't melt the paste. it works so much better than using a hot plate, so I officially declare it state of the art as of today. #SMD #soldering #solar #solarpunk #flwr #anal0g_flow3r #sks2026
