I am having a problem soldering the Jumper Pads on the PCB of the Rainbow Cube kit.
Solder sticks to the pads but will not bridge (one only gets little balls of solder on each pad) and one of the pads is now damaged due to repeated attempts to solder it.
I’m using a thin Lead Free Solder and an iron with adjustable temperature (but no thermostat).
What is the purpose of these Jumper Pads?
Can you advise of a way to join them?
How can I deal with the damaged pad? Can one easily wire around it?
