How to Use Solder Paste (Soldering with solder paste & heat gun)

[@megahertz6787]

I made a portable pencile hot air gun & a video about it on my channel , it sounded like that too when the aquarium pump I used was far away lol but now all you hear is the brushed motor & gear assembly because I had to use a cheaper pump & smaller hose so everything fits in a small travel case . The pump is battery operated anywhere from 1.5v - 5v depending on nozzle size & what your work demands . The pump dose have a 2 speed switch but I think controlling the voltage to the motor is a better method because you can get the airflow just perfect for your needs

[@coladict]

I can see why this isn't the most popular method. It's much easier to make a mistake without noticing it. With the more traditional method, if you make a mistake, you see it.

P&T IT BROTHER i have a question I am going to be using a hot air station for first time and I am going to solder transistor and resistors to a diy project shall put the air flow to 10 or 35 as you said

[@PTITBROTHERGravenhurst]

It all depends. Since all hot air stations are different, you need to practice to find the best temperature and the power. Start from low power and temperature and increase

[@bebelscomet1716]

So if you add the paste there’s no need to solder?

[@nilolee2426]

Help me out, I don’t have hot air to remove this type of component, can I use a regular iron soldering without temperature control, I’m using weller 23 watts soldering iron. I’m afraid I might burn the new part, any advice? Thanks

[@PTITBROTHERGravenhurst]

You can try, but it won't be easy. If you believe that you have a good soldering skills, then should be okay.

[@GodzillaGoesGaga]

Yes you can. As long as your tip is fine enough. Put a scalpel blade behind the pin and use solder wick and flux to remove the solder. Do this for each pin and try and get the pin to lift off the board. Repeat until the pins are clear. You have to do this slowly and methodically. Won't work with a device that has a central E_PAD or GND pad. Personally I wick the whole bank of pins first and then focus in on individual pins. Sometimes it's easier to use an adjacent pin as a leverage point. Use a very sharp blade (and microscope if you need it).

[@obfuscated3090]

Practice on scrap components first. NEVER practice on your workpiece.

Hello Sir, what is full name of this paste for soldering

[@PTITBROTHERGravenhurst]

It is chipquik soldering paste

[@bionicftmprosthetics375]

Is 752 degrees Fahrenheit really safe for the board? The creator mentioned using 400 degrees Celsius. It seems a bit high j

[@PTITBROTHERGravenhurst]

Lower temperature is always better. If you preheat the board, it is easier to do soldering with lower temperature.

[@SwingMotor]

Thank you for creating this

[@tuxede]

I solder prototypes of big devices in small series sometimes, and my experience is: 1.Hand-soldering small 2 pin elements (resistors, leds, caps) is very time consuming and hard - hot air and solder makes it much faster and easier - they just pop into place. 2. Your method of aplying solder paste looks very inconsistent. I add some proportion of flux to the mix - paste becomes more even, flows more easily etc (talking about hand-aplying the paste). 3. For me, just blowing air doesn't work/seems too dangerous. I preheat the board to 90-100C in case of leaded solder, and hot air to 350C. 4. Lead-free doesnt work for me - I tried preaheating boards to 160C, even then I had trouble controlling the procces. 5. My paste's fumes are very nasty, I put my extractor very close to board and on high volume, thus the whole procces is becomes harder, but I don't inhale the fumes. May be the reason lead-free doesn't work for me. 6. May try bismuth solder paste, seems more apropriate to what you're doing. You wouldn't have to overheat your components.

[@PTITBROTHERGravenhurst]

Good points. Preheating really helps soldering and desoldering.

[@giga10onlinestore63]

Really excellent! Thank you for creating this video!

[@ahra3916]

may i know the specifications (brand, size ,etc) of the heatgun that you are using? i believe that your demo is under a magnifying glass.

[@marekeos]

I have a regular heat gun. If I use it, will it not soften or de-solder the other components next to the one I'm trying to solder??

[@PTITBROTHERGravenhurst]

Sure it will. You need a heat gun with a narrow tip. That is why people buy a professional quality heat gun station. You can change the tips with those ones.

[@nixonz3952]

Can you use soldering Paste on a Graphicscard? Im asking because I think it could just melt because of the low melt point From the hot gpu while gaming. And I never seen anybody use it or talking about it, who‘s working on Graphicscards.

[@PTITBROTHERGravenhurst]

I am not sure but depends on the application, people use different types of solders with different melting points. For a device which produces more heat like a video card, I don’t think you can use a solder paste with a lower melting point

[@nilolee2426]

I just bought soldering station form Amazon, so what’s the correct temp(Celsius) for hot air to remove ics chip and smd transistors? And what’s temp on the soldering iron to solder them(ics chip and smd transistors) back to the board? Thanks

[@PTITBROTHERGravenhurst]

Typically, I do use 350C to 400C depends on the situation.

[@jimmatrix7244]

@@PTITBROTHERGravenhurst What are the situations?

[@PTITBROTHERGravenhurst]

Depends on the solder type, I guess. Some solders have higher melting point. Some are lower

[@jeremyjones7590]

Also depends on the size of the nozzle used on the hot air gun. I found the really thin nozzles were pretty useless for desoldering things at high temps because the heat applied is too narrow. However at the lower temps used for soldering with paste, it might work better. Always best to experiment with a practice board first if possible.

[@wilberthernandez7887]

do i need to use wick after?

[@PTITBROTHERGravenhurst]

You mean after you remove a component? If that is what you've asked, then yes. It is recommended to clean the solder residue.

[@jaeyongoh3816]

Do we not need to apply flux before putting paste?

[@PTITBROTHERGravenhurst]

The solder paste already got flux in it but you can always use more flux

[@jaeyongoh3816]

@@PTITBROTHERGravenhurst does every solder paste have flux in it? I have a paste that came with the soldering kit that i ordered. My paste is in a solid state but yours look pretty liquidy, so im wondering what kind of difference there is?

[@PTITBROTHERGravenhurst]

For most of them, yes. It's got the flux already. That is why my soldering paste is wet. Dried out soldering paste means it's expired, and you should get a new soldering paste. They last about a year since you open them. It is not recommended, but you can mix your dried out soldering paste with a liquid flux.

What's the copper strip at the end of the video called? And why is it needed?

[@PTITBROTHERGravenhurst]

It is a solder wick. You need this when you desolder. It absorb the solder if you apply heat

@@PTITBROTHERGravenhurst after disoldering or after soldering?

[@PTITBROTHERGravenhurst]

Not after. You need this to desolder

[@lepidoptera9337]

Soldering SMDs with solder paste without a properly adjusted reflow oven is an expensive idiocy that no amateur should ever get into. Just use a very thin solder, a fine tip and plenty of flux and your SMDs will be perfectly happy.

[@JHenrySlentz]

Bump to stress importance of a reflow oven. NOT FOR BEGINNERS. These videos downplay the expertise required for laying down ICs, knowing their individual heat tolerances, etc. I'm sure this video and others like it have fk'd up a lot of peoples expensive sh*t :D

[@mealticketscrub2561]

Can I use this same process to solder speaker wires?

[@PTITBROTHERGravenhurst]

Maybe, but when it comes to soldering a wire, you better use a soldering machine. Watch this vide for soldering a wire: kzbin.info/www/bejne/eoCliYqCdrGnfcU

[@obfuscated3090]

For speaker wires because they're stranded I apply liquid flux using a "printer swab" for precision then use a soldering iron to tin the wire.

[@PTITBROTHERGravenhurst]

it is very hard to say the exact temperature when it comes to soldering with a hot air. Because there are just too many factors that affects the hot air soldering. Like the board temperature, hot air station performance, type of solder, and etc. The best way to find out the right temp is practice. Just keep trying to solder and desolder with your soldering gears until you find the best temp.
