What products do you use besides the hot iron? I'm having a hard time to remove lead free soldered components just with the iron

Even if the part is not working the board most probably is. Hot air gun costs times less then one supermarket trip

yes and no! Dont do that in case u intend to resolder that USB connector somewhere else cause, USB connector got plastic parts thats gona melt... or to not heat it much... What I do, I first desolder holding left and right pin that fixe the connector to the PCB, then desolder the rest 5 Pins, this why if it is done well the connector can bere-used 😉

@@DrZipZwanok

Not really. Depends on how tight the components are in the board and most component can handle that heat otherwise hot air will also damage other component with how they heat up not only the component you want to remove.

If the chip is faulty and needs replacing, so what?

With some old boards u will pick up the the foil...

@@jay22alco that's why you have various sized tips on your hot air gun....

true specially if you use cheap irons and it gets dirty easily

Which flux

@@apavithran6756 soldering flux also known soldering wax

Yes. I liked that too.

i think it's kapton tape

I can even smell it from here 😁

😂😂😂😂😂😂😂

Aonde agente encontra esse material pra comprar

@@wilsonlimeira4252 se chama pasta de solda ou fluxo de solda, geralmente vc encontra para vender em lojas de componentes.

Ty friend!

Thanks. It was so cringe. I would have commented the same.

A dead component is one of the biggest reasons you might want to desolder something

I could disagree with you. All temperature sensible components I've successfully desoldered and then soldered again are still working. I couldn't tell the same about heat gun...

Your comment just proved how much you know about soldering... Although I do know both techniques this one is even safer than hot air as the heat is only provided to the soldering points - not to the core of a chip or PCB that acts as a heatsink like it is in the case of using hot air. Both techniques have their advantages and disadvantages but what you've said it totally wrong.

This is very costly....not good

😂😂👍

Да для варианта в полевых условиях самое то используя подручные средства, лучше не придумаешь

No it is not useful because the components are exposed to heath too much time and are internaly destroyed

Sorry so late but, "Failed amazingly"? Did you mean "Miserably"? lol

@@paulreeder5241 It was amazing how bad I failed that job...that was the intention of the sentence. It was indeed a miserable attempt. Have a good one mate.

so true . : )

And it's even more when you actually do it, I love the process

Agreed

same

I can't stop watching soldering videos. XD

You cut the two two or three leads off, then you can easily remove the package.

what is the brand of the flux?

@@Pixell_Eletronica Mechanic, obviously. Watch the video until the end, all the tools are listed.

This should be aimed to replace the desoldered part, not to fix the pin connection from bad soldering, so yes, next step is to replace the part.

Yes

@@aswingsharif6729 This makes sense, tq

@Soren Kylo @Maxwell fuck you scammers, who are also spreading unhealthy insecurities

Even with a hot air technique, what happened to the caution we were told to have when soldering so as not to overheat delicate chips? Removing parts is one thing as they're going in the bin but got to solder the new part back on. These things are done with pin point accuracy by machines in factories for a reason.

🤣🤣 LoooL...

Wicks are pedantic. A big blob till tweezer-time is faster. Every method has merit. Know your limit.

If they're already broken and need replacement I guess it's fine anyway.

Desoldering braid is what I use.

Awesome

Still a newbie so don't know about the temp. But this is desoldering not recovering components. So yes most components will be dead after this treatment.

Nek minnit...

Was just wondering about the heat

I dont thinknso: Wave soldering which is very popular in board factories is the same process for building board.

Yes you are right.....

If a component is being removed, more often than not it has failed so what's the issue??

@@ro63rto or you are removing it from a donor board

Me too, I'm using all that methods, but wrapping some wire around the tip of soldering iron and bend it into right shape is better that a U-formed piece which is only touched by the tip, you need ways less solder and it goes faster, the parts don't need to be heated up that much. To be honest we both kind of copy this idea from special iron tips, didn't we? 😂

Lol, read the description.

Fried

I think they are reusable. When desoldering using air, you also apply heat to whole component and not only its legs. So I think the temperature on the component is not so far from air desoldering

The resistors are probably reusable. With active components you run the risk of heat damage. But sometimes They work

@@neilkurzman4907 well if we actually check the internals of ICs, we'll see that there are very thin wire going between the chip leg and the actual crystal. I don't think much heat can be transferred through it. So as for me, heating the IC's case is way more dangerous than heating its legs

@@eugenegrebionkin The plastic also doesn’t accept heat very well. You can guess, but the question is is it worth reusing a potentially damaged component.

Lol he is taking the iron on top of the components

corisco tupi this is supposed to not damage the pcb If you solder parts of they are anyway damaged already Plus a resistor or capacity in that case isnt too expensive If you know a clean way to desolder a 32 pin IC (SMD, i forgot the exact housing) Then please tell me, and no the desolder copper mesh doesnt work cause you will overheat to over 230C (as stated in the datasheet)

I bet all those components still work.

ivo kostić absolutely true But i am a dude sitting at home, not wanting to invest 20$ into a solder and more money into flux When i remove an IC then i remove it because its faulty, i dont have to be careful And heck even if it is still working, really, 40 cents for a new one Even the effort to desolder it like that is too high Still you brought a solution, never seen of such a solder Again still somebody like me or you, will never use this Even at work, my boss says to just desolder them quickly, or like you said cut them of (but then you gotta use desoldering wick, which in return wastes again more time, even if you dont use desoldering wick) We live in a meta, where every part that is damaged (partially) gets thrown away. I send my laptop to acer after using it for 8 months They said it was exposed to more then 20%RH and that part the warranty doesnt cover.... after asking if they can repair it, they stated it would cost 90% of the laptops price....
