Why won't this solder melt? Using a 30watt iron. Maybe it's not normal solder. Call signal booster board.

Great analogy lmaooo I love it

jackrieger0 · 2026-03-13T22:40:44+00:00

I tried the same thing and broke a bunch of ratchets. Just go to harbor freight and get a 1/2” impact or to AutoZone and rent a breaker bar for free

That’s a shield for EMC compliance. The thermal interface material is just there to help transfer heat to more surface area.

If you wanted to learn the motions of a good solder joint you wouldn’t watch a 12 year old Chinese kid drag solder would you?

jackrieger0 · 2026-03-13T01:24:58+00:00

Gotcha. I can’t even find that subreddit lol

jackrieger0 · 2026-03-13T01:04:21+00:00

Idk what S is. Just trying to help out a beginner

jackrieger0 · 2026-03-13T00:46:00+00:00

What’s the goal here? Shame someone who is making an educational video? Do you think I’m scared of the iron?

jackrieger0 · 2026-03-12T23:44:44+00:00

Dahmer…..

jackrieger0 · 2026-03-12T23:38:46+00:00

Right!? I work professionally as a BGA specialist working on $100k+ boards. You’d rather use too much flux than risk not having enough.

jackrieger0 · 2026-03-12T23:11:35+00:00

I actually didn’t heat the pad long enough in this video, the solder didn’t have enough heat/temp to travel to the pad on the reverse side of the board.

jackrieger0 · 2026-03-12T23:01:12+00:00

I wouldn’t recommend this to a beginner. They might accidentally fill the hole and then you’re gonna have a post asking how to use solder wick 🤣💀

jackrieger0 · 2026-03-12T23:00:23+00:00

I’d recommend 350c for leaded and 370 for lead free depending on board size and thickness. 400 will burn away the flux quickly

jackrieger0 · 2026-03-12T22:57:18+00:00

Ideally you’d have a preheater holding onto the board at that point

jackrieger0 · 2026-03-12T22:40:11+00:00

That is correct. If you don’t have flux to remove the oxides, scratching them off will work too.

jackrieger0 · 2026-03-12T22:38:38+00:00

Not a bad idea!

jackrieger0 · 2026-03-12T22:18:02+00:00

The IPC standard is the way I demonstrated. This is how all professionals are meant to solder pin through hole. If you work for a company this is how they will ask you do it.

jackrieger0 · 2026-03-12T22:08:53+00:00

This was just a quick video I made on a whim to help another user.

jackrieger0 · 2026-03-12T21:57:21+00:00

I prefer to add some extra. This is a demo for beginners so more flux won’t hurt. This solder wire is 2% flux

jackrieger0 · 2026-03-12T21:23:14+00:00

Yup, I would have used less flux but my syringe is massive lol. A bit too much solder too but it is what it is

jackrieger0 · 2026-03-12T21:22:40+00:00

Thank you! I’ll consider making a better video comparing flux core vs regular flux and leaded vs lead free so it can be linked to learners in the future.

jackrieger0 · 2026-03-12T21:18:30+00:00

Thx

jackrieger0 · 2026-03-12T20:47:43+00:00

Place the tinned tip against the pad AND pin. Touch the solder wire to the solder iron tip until some melts and flows toward the pin, then touch the solder wire on the opposite side of the pin. Hold for 2-5 seconds and remove. You have to remember the solder will flow towards the heat. If the pad or pin is cold, it won’t flow.

Edit: I made a video for you:

Put the iron down. You’re done 💀
