Ok, so over the 18 months I’ve been building, flying, crashing and rebuilding quads, I’ve become quite adept at soldering. Mainly by overheating flight controllers, ESC’s, 4-in-1 ESC’s etc. However on the odd occasion, I’ve come across the following.
I apply the solder (Armattan’s own) with a freshly fluxed and soldered hot iron for the minimum time possible to the pad. However, the solder will not stick to the pad. No amount of using a fibreglass pen or using a flux pen to clear the crud will get the solder to stick.
Now tonight’s fun is with a brand new 4-in-1 ESC board from Banggood (Sorry Alex, you didn’t have the one I wanted in stock). So the question is this - am I doing something wrong, or have I just got a dodgy board which won’t solder?
p.s. it’s all the pads on the board, not just one.
