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.

You said to add solder between the tip and the component. This is very important. Well done!

[lefteriseleftheriades]

1. Use a temperature controlled soldering station. When you start melting, the temperature quickly drops, so your temperature controlled station needs to pump energy to keep the tip at the proper temperature.
2. Use that flathead tip rather than a pointy one
3. Use flux. It will make soldering 10x easier
4. If you are soldering a sensitive component you can use a heatsink on the other side

Guys, a good quality flux makes a WORLD of difference, and even if it's a bit pricy it will last you long enough to make it more than worth it.

You also want to make sure to have atleast 330° of wetting around the pad to comply with IPC class 3 requirements. But it is a good idea to allow the iron to sit with the solder for a little bit. Ot helps allow the flux to evaporate and prevent cavaties and dry joints. Also kake sure to put enough solder into the through hole so it fills up atleast 75% of the barel. Great vid.

The bubbles indicate that something (other than the flux core inside the solder) is vaporising, i.e. something is being overheated and burnt. The bubbles form cavities inside the solder joint which will eventually result in a "dry joint" and consequent failure (possibly intermittent failure) of the circuit.

I'll be sure to share this with my friends in three weeks on monday.

I use a 90° flipped board and start from the lowest point. The added heat is will preheat the next joints upwards and this position let the solder sucked back automaticaly into the galvanized hole if the tip temperature is any good. The air bubles olso goes upward and will not disturb the solder to flow.
This way u can work faster and can leave the perfect amount of solder on every spot like only the solder bath can do.

I’ve been soldering electronics a lot when I was a kid and I was very good at it. To me it looks like you’re holding the iron too much time on the board.

[davidlaraezm]

Great video, specially the music combination, it's so relaxing to learn this way. Kepp up the good work!

[peixediabodabahia]

Instructions unclear, solder went flying everywhere

[ejon]

Yes, exactly what I need. Keep em coming 😊

[jimtekkit]

Solder should never bubble or spatter. As you're flowing the solder on to the joint (which will be easy to do with good flux), the meniscus will steadily shrink down as the solder flows through to the other side. If it acts like a volcano then something is wrong.

[LockWizzard]

I don't see any flux. Is this recommended?

[quenchtv]

Ganyan din po napanuod ko na nagrepair yan din problema muntik na raw sya sumuko 😂😂😂

[Lectrodude]

Those bubbles can be a sign you left your iron on the pad too long and the board is beginning to delaminate. Hold your iron on the pad for no more than 3 seconds.

[chvtney]

Wow that was a quick and accurate guide. WTH 😂

[Chris-___-]

Wow this would fix so many joints if everyone this

[jowee]

Since i havent seen someone say it yet, these solder joints look cold af. They should be a smooth reflective finish and not look like popcorn drywall.

[blacknoir]

bubbles are also from the flux in the flux core solder boiling away

Lays down a dry joint as he says perfection
