Lab #4: Jumper wires

This video demonstrates how to place surface jumper wires between different parts of a PCB.
Two techniques are shown: bare copper foil traces (good for short, high density runs) and insulated wires (good for longer runs or high current). The bare trace is insulated with 2-part epoxy and the wire is attached using ultraviolet-cure polyurethane.

Why do you not use UV curable soldermask ? Curious

Honestly? I don't have any on hand. I keep meaning to pick some up and experiment. The epoxy method works quite well from a mechanical/electrical perspective, just hard to get an exact color match with the tints I have.

@@AndrewZonenberg Yeah it seems if you were deep in a mod or repair, you do not want to remove the board move it to heat, maybe you have probes attached and maybe a mess all over desk ( maybe lol ), uv flashlight and blast it in place, I have some UV green I have not tested it yet.
