Cutting and joining a LED strip that has no solder pads?
those LED modules are so close together that there's no room to add junction points for cutting it.

just cut the strip using a hacksaw (or whatever works) and solder your three wires to the existing solder on the component leads.

secure the wires with 2 part epoxy or cyanoacrylate glue.


the red wires are the power wires and should be thich-ish wire the green wire is the data wire and can be thin
