Thank you for making these tutorials. I've been watching all your videos and practicing. My soldering has improved immensely. Full credit to your clear instructions and high quality videos. You have a knack for teaching.

I watch all of your videos. Your videos are spot on and i find them very helpful. I have only done mostly through hole stuff and the surface mount stuff always seemed like it was out of my realm of ability. But, after watching all of your videos i feel much more confident. now i am playing around with surface mount soldering. Thank you for taking the time to provide us with the knowledge and confidence to tackle this technology.

Hi. That was extremely impressive. The quality of the joints on the QFP (which I'm mainly interested in) was amazing! Thank you. Whilst I'm sure it's mainly your technique, just to help, could you please tell me what solder and flux you're using (there seem to be loads)?

I've tried different tips on an old PLCC I first desoldered from an old PCB with low meld solder, cleanup and resoldered it again with amtech flux. I used JBC c245-931 spoon type tip which worked but not as clean as yours. I also tried a small cone tip, 0.4mm point but that didn't go well, couldn't get the solder on the pad. A bent conical tip with the wider side over the pins I could drag solder, though there are a few pins that are bridged, and removed with wick. That gave the best results so far. The conical and bent tip were off brand jbc though, that came with the T3A station. Having a microscope really helps a lot, I did it with a magnifying glass but had to check after soldering. I'm planning on using a mobile and microscope/zoom app with a phone holder. First tests seems to work. A poor mans microscope lol!
Thanks for sharing, this was very helpful! It looks easier than it is, it really takes some practice but it's not really that hard. Just practice on something that you can mess up without worry before soldering a $100 chip or something.

It really helps, seeing someone do it properly! Thanks for these.

Very nice video…. This is the first soldering tutorial where I actually like all joints. There are some horrible videos out there.

Could you add the type of paste, solder and flux used to the video description to get such nice results?

🙏

Beautiful work. Relaxing to watch a top notch pro work calmly.

I’ve done hand soldering using leaded solder for many years. I could easily switch to lead free with absolutely no problem. I’ll use that liquid flux, the low temp solder to aid with removal and then replace the chip.

I learned a lot from watching this video. Thank you.

Not only your soldering technique but how you hold the iron tip is very helpful to know. I'm taking notes keeping them handy on the workbench. Thank you for taking the time in making this video easy to understand along with detailed instructions and quality photography, most appreciated! Now if only I can steady my hands to complete the job. 🙂

Great video from a pro, I'm learning loads from you for my own channel, doing audio upgrades 👍

Thank you for your great video.
I had to solder some TQFPs a few years ago, and couldn't find any decent guide videos then.
With the short vertical-edge contacts on the TQFP, and the pads on the PCB I was using not extending very far beyond the chip, there wasn't a lot of space for excess solder to go, so there was a rather fine line between too little solder, and too much.
By trial and error using some cheap sacrificial chips (the ones I needed to solder were rather expensive), I found out the easiest way for me was to use excess solder paste for the hot air soldering, and then clean up any bridged pins later.
I couldn't get cleaning up with braid to work, though I don't use braid much, and I may well just have been doing it wrong, but it was surprisingly easy with just a soldering iron.
Using a relatively large (~2.3x4mm) flat oval tip, a clean and freshly-wiped iron drawn along an edge of the chip soaked up excess solder very well, and could even clear most of a whole line of bridged pins on the first pass. I guess that the large area of the tip gave plenty of space for the excess solder to go.

Personally I prepare the pads with solder and then I apply the IC with flux, then I use my hot air station while holding the IC with my tweezers down. It works every time for IC's where they have too many pins. A nice microscope with clear view always helps though.

[annacersongor]

One word, awesome ! Thanks for sharing.

[gatrezehn]

Thank you for clear and helpful videos

[intoxicode]

Learning the basics of hot air soldering recently for my repair business. So I can take on more advanced and harder projects. But my biggest concern is finding a good pair of tweezers...

[ALGERIEECONOMIE]

Excellent stuff, thanks for upload your videos ....very informative.

Hi there
Amazing and entertaining instructional vids to be sure! Ty.
You mentioned, when doing the Silicon chip, that you put a little bit of flux on your iron just before soldering the legs? How do you add the flux do your iron? Do you dip it in the flux?

[kennith.]

Thank you. Great quality and information.
