I’m trying to solder on the flex cable for a PicoFly. I’ve added some solder to the bottom two points that are touching the metal surrounding the CPU. However, I seem to only be making a bigger and bigger ball of solder when trying to melt it. I’ve upped the temperature on my iron but that doesn’t seem to be doing anything. What am I doing wrong?
So to solder properly, the important part to heat up is the metal you are attaching to, such as the copper pad. Hot solder on cold metal doesn’t really work. That is the most advice I can give. Try searching for some videos on EEVblog. That is how I learned to solder, even if I am not super good.
