How Do You Solder Wires To A Circuit Board

Be careful when soldering pads especially those that are close together.

How do you solder wires to a circuit board. Remove the iron and the solder wire and inspect your solder joint to see if it looks okay. Keep the iron on the joint while you add solder. Use tiny cable ties and slide it through the circuit board and wrap it around the wires to hold them in place.

If you do want to solder them directly you can make it more robust and marginally better looking by drilling holes wide enough for the wire insulation to fit snugly looping the wires through those holes and then soldering them. Use solder wick or a solder sucker to remove the solder from the holes. First you should bend slightly devices leg.

Alternately melt the solder in one hole then bang the PCB on a table dont over do it. The heated wire and copper on the board will melt the solder and it Should flow very uniformly around this solder joint quite quickly. Hold it there for 3-4 seconds.

Soldering components onto a circuit board when the leads can be pushed through holes in the board is the easier of the two methods of soldering small components onto boards. Heat them for a second or so before you apply solder. There are two dominant types of.

Get your soldering iron really hot wipe some fresh solder onto the tip and wipe it off again by drawing the tip across a damp sponge this cleans or tins the tip. Assuming its through hole hold one end with long nose pliers heat the solder until it melts then pull the lead out of the hole. Repeat for other end.

This provides strain relief so that the solder joint isnt taking a significant mechanical load. Hold it on the wire for 3-4 seconds. The electronic circuits are made of PCB components connected to each other in a meaningful way to function as per the design specifications.
