How to Hand Solder a Perfect THT | JBC Soldering
A well-formed THT solder joint ensures reliable electrical connections, preventing failures and malfunctions. Here is a step-by-step guide on how to hand solder a THT component to secure good electrical conductivity.
01 - Always use the lowest possible temperature according to the mass around your component. (see note #1)
02 - Ensure your tip is properly tinned and clean of oxide.
03 - Touch the pin with solder and add more solder wire between the tip and the components so that the solder melts.
04 - Withdraw the solder wire while keeping the tip in the same position for a few seconds, allowing the molten solder to be uniformly distributed on the component and the pad. (see note #2)
05 - After a few moments, lift the soldering tip and allow the solder to air-cool.
06 - Check that the menisci have formed properly between the component and the pad.
Note #1: More mass will implied more temperature
Note #2: The presence of bubbles is a good sign; this means that the solder is flowing down the through-hole joint.
