Can I solder jumper wires?
Jumper wires soldered into plated through holes must be discernible on the opposite side. Just like a through hole component lead, you should be able to see the outline of the wire in the solder connection. Jumper wires soldered to lifted or clipped component leads should be insulated to prevent shorting.
How do you solder jumper cables?
- Step 1: Strip the Wire. Open the strippers.
- Step 2: Tin the Wire. Twist the end of the wire to clean it up a bit.
- Step 3: Solder the Jumper to the Board. Poke your tinned jumper end through your PC board.
- Step 4: Clip the Excess. Set your cutters very close the base of the wire.
- Step 5: Desoldering the Joint.

How do you attach a led to a resistor?
Clip the “+” leg down to about 1/2 inch long, on both LEDs. Do the same on the resistors, clipping one end to the same length. Resistors don’t have a + or – side, either end will do. Twist the clipped leg of the LED and resistor around each other. Needlenose pliers can help.
How often should you clean the solder on LEDs?
Every few connections, or once a minute or so, clean the tip on the sponge and re-tin it. Otherwise the flux all boils away, the solder gets gummy and doesn’t flow well. Repeat the soldering for the second LED. After soldering and cooling off, trim the other leg of the resistors and the LEDs to about 1/2 inch.
What’s the best way to put solder on an iron?
Wipe both sides of the tip against the damp sponge to clean off any old sooty residue. Or if you have the brass “Brillo Pad” style sponge, just stab it with the iron a couple times. Add just a small amount of solder to the tip of the iron…
Do you have to heat shrink LEDs before soldering?
After both connections are soldered and cooled, slide the heat-shrink tubes to butt against the LED, and apply heat as before. Another common heat-shrink error is forgetting to put the tube on the wire before soldering. I’ve been soldering since dinosaurs roamed the Earth and still make this mistake.
