Apply flux before soldering?

[@cozmicboy1]

@@novanwinli5049 nope, no flux given.

[@howardlam6181]

@@cozmicboy1 You can't do this without flux. The solder would just all stick together into one lump.

[@ege8240]

​@@howardlam6181solder has flux in it no?

[@ecurepair]

yes but it helps a lot to add more. The flux in the solder usually burns up too quickly for drag soldering. If trying to do it with only flux in solder then I'd recommend pin by pin.

[@robertmiles9942]

The first time in history anyone has ever disclosed their temp setting

[@foodhatesme]

The temp just needs to be hot enough to turn the solder into liquid... his temp settings wont help you if your iron doesnt report the proper temp or you use higher temp solder.

[@neeraj563]

Beautiful technique man. What type of solder, flux and wattage of solder used?

[@ecurepair]

Solder was REL22 (lead free), Flux was Kester 1544 & iron I use is the Metcal CV5200. I think its 80w but uses a different heating system so not sure how that correlates with normal systems.

[@kelkilkat]

I imagine this technique takes some practice. Very nice video. Where does the desoldering liquid go when you finish, does it evaporate?

[@ecurepair]

Some evaporates but much of it will solidifies and should be removed once done.@@kelkilkat

[@Elixisty]

There is NO way, my solder would come off onto the pins like that. Image every other pin with a blob of solder in between.

[@ecurepair]

You can do it. Keep practicing. Most important is good heat transfer and good flux.

[@Terekhov_Fyodor]

To get rid of excess solder, a soldering wick will help you. The main thing is not to be afraid, and train to solder!

[@hightttech]

FLUX FLUX FLUX and a good tip. Always leave your tips tinned when not in use; they will last years. And if you really want to impress the ladies with your drag soldering, buy hoof tip (sometimes called reservoir tip).

Just need a little more heat and flux

[@stefanweilhartner4415]

[@XevilangleX]

What temperature is your iron? I used various types of solder and even used at amtech 559 flux and I get bridges when I do a HDMI repair. Sometimes I'm able to get it but it's not consistent. I have a pinecil v2 iron as well. And I even slightly soak the tip. When I add a ton of flux and drag the tip on the pins it either doesn't drag or move or it just slightly moves but transfers the bridge over to the next set of pins.

[@ecurepair]

The tip i was using is a fixed 393c. I have no experience with the pinecil but it sounds like temp is too low or the iron/tip is not delivering the heat well. I was using my metcal in this short, it transfers heat extremely well. I have a full video using a iron more comparable with yours that you may find helpful. kzbin.info/www/bejne/iYTFgmCwgb-WpsU

[@XevilangleX]

@@ecurepair That might be the case, I was using a claw tip or a thin tip with a slight bend on it. Saw other knowledgeable people using it and in my head I was thinking it work help to reduce contact with other pins being that is small so I can avoid bridging. Ill check out the video. I appreciate the help man!

[@XevilangleX]

@@ecurepair Great video man, honestly that's actually what I use as well, is a hoof tip primarily, especially after having issues with the angle tip I said above. And I have the EXACT same issues you had in the video. I'm going to get a tip you said you use and practice so more. Thanks alot man!

[@ecurepair]

The smaller tips are not too good for this type of thing. You'll want something with more surface like a hoof tip or knife tip. The small pointy ones are really only good for small hard to reach area's (imo)@@XevilangleX

[@ilkeryasinyildiz]

I bent so many pins while trying to use this technique 😂 The Roland chip has 20 pins each side. 80 total 🤦🏻‍♂️

[@ecurepair]

Its a feather touch for sure. Mostly your just dragging a solder glob and not really touching the pins with your iron tip all that much. This video my help a little kzbin.info/www/bejne/iYTFgmCwgb-WpsU

[@ilkeryasinyildiz]

@@ecurepair Yes, you’re right. the solder lead was in a bad shape and the mainboard was 30 years old. Thus makes it prone to forces. I resoldered 3 sides perfectly but screwed up the last one. Afterwards, I realigned the bent pins with tweezers and completed the soldering again. The JV-2080 sound module not worked :( I’ve seen some residual solder behind pins where I can’t reach. I thought the chip was a through hole one, but was an SMD 😔 I learned with the hard way.

[@ecurepair]

There is still hope. Rework the mcu with flux and hot air. It will clean up the residual solder behind the pins nicely.

to this day i still wonder why so many hobbyists do SMD with an iron... solder paste is so much easier, just dab a small amount on, and heat up, it will also self-align the chip... an iron should only be needed for reworks and touch-ups...

Ive used paste on this same module many times. Dragging it is much better tbh.

[@fortheregm1249]

why leadfree ? you like the challenge ?

[@ecurepair]

Not much difference in working with either for me to be honest. Automotive stuff in the US has been leadfree for a long time so usually I do it just to keep with what's already there. I do use leaded sometimes, nothing against it or anything.

[@tubeo94]

Can anyone explain to me why when he drag the tip the solder doesn’t go all over the place but just stick to the connection?

[@ecurepair]

Solder naturally wants to form into a ball due to its surface tension. When you drag the soldering iron across the pins, the surface tension of the solder causes it to adhere to the metal surfaces it comes into contact with (pins and pads). The flux helps it keep it all wet and flowing well so that you can control the distribution of the solder better.

[@tubeo94]

Wow, thanks. I have no intention in fixing electronic at all. But still want to know how things work.

How come the soldering doesn’t get stick between two legs

[@ecurepair]

Solder naturally wants to form into a ball due to its surface tension. When you drag the soldering iron across the pins, some solder will adhere to the metal surfaces it comes into contact with (pins and pads) the rest tries to form the ball with itself from the surface tension. The flux helps it keep it all wet and flowing well so that you can control the distribution of the solder better.
