June 1, 2019 Reply Jon I like the way you flip between pronouncing it ‘solder’ and ‘sodder’. That way you please the Australians AND the Americans. June 2, 2019 Reply çağrı yağmur Great job thank you for your effort June 4, 2019 Reply Артур Тим If you will make assembly small components with "Mechanic's" flux, your soldering will be better… June 4, 2019 Reply Kevin Liu QNF? It’s QFN! 10:14 June 6, 2019 Reply AG_ from _83 Here's the problem I have with soldering. The solder just goes straight to the iron tip and sticks there. Is this because its a cheap soldering iron and the wrong temperature? Or maybe cheap solder? I only ever do smd June 7, 2019 Reply Jacek Renkas I recommend 0,2 or 0,25 mm solder for small SMD components 🙂 June 11, 2019 Reply Adrian :P What happens if he accidentally soldered two pins together?

Valentine @GreatScott! and fellow viewers; i have been in love with electronics since i have use of thought, but i had never had the oportunity to throw myself into studies before, next year i will have this oportunity, what studies should i apply for, if i want to learn this type of profession?

I expected more July 3, 2019 Reply idan w QNF is for hot air soldering.i see the majority of pepole on youtube use hot air for that.you just need to set it to a bit lower temp (280-290) and do it patiently July 3, 2019 Reply Gabriel Freitas Pcbea mkay?

July 10, 2019 Reply MaximusPayne Do you have any tricks for soldering pin headers? I hate it because they always fall off when you turn over the board, or if you are lucky they just get soldered crooked.

I really need some… July 15, 2019 Reply Landy 20 Most of the parts used with a pcp here are intended to be kept on the reel, fed into a machine, and placed by a robot onto the pcb. PCB would already have passed through a "printer" with a stencil and would have solder paste exactly where neccessary. Then sent through a low temp oven for perfect curing. Don't feel too bad about trying to solder these tiny parts and doing a mediocre job, it's intended for robot precision. July 16, 2019 Reply Optimus Prime It's not easy for me. Gonna take time to learn good soldering. July 17, 2019 Reply da1otta I also use Stannol solder. I'm very pleased with its quality. However, on perfboards, I prefer to make connections using the clipped of leads of components. It saves solder and I don't have to touch up the connection each time I heat it up to add/replace/remove a component along it.

When people say sodder it sounds like some perverse sexual act and shows their ignorance and laziness in their language. You have an accent but You get that word right which is a very pleasant change. July 27, 2019 Reply John Bartley Great video!

His mind would have melted if he knew how small all those components go. July 30, 2019 Reply Tomas Maliauka I think BGA package is the hardest to solder and reball if needed to resolder again. It would be nice to complete the soldering training by adding training on the BGA package. July 31, 2019 Reply Dark Knight Wish I could read schematics! August 1, 2019 Reply VOVAN781000 …Very bad August 1, 2019 Reply Houyhnhnm Tell the good folks about bad soldering product. 90% of solder and flux is garbage from China. Here's how you will know: Every soldering iron including fixed temperature irons are hot enough to melt solder. If you can't melt fresh solder from the spool/coil then toss that solder into the trash immediately. Never overheat the tip just to melt solder, 300 degrees is more than enough. Too hot will destroy the stainless finish and it will begin to oxidize. An oxidized tip will not hold solder. Keep tips clean and always tin it. If you melt solder and it balls up and doesn't stick even with flux on a good tip, it is garbage solder. Toss it into the garbage. Never try to work with that crap. Many components out there use garbage solder. If you're trying to desolder and it won't melt, simply clean the area with alcohol, add flux, then melt fresh good solder on top of the old solder until it melts everything, then suction it away. Don't bother with braid, it will not absorb garbage solder. When in doubt, use leaded solder whenever possible. Give the folks some links to the best solder and flux.

August 11, 2019 Reply code beat I prefer to use the epoxy green with thinned pads perfboard, better quality, no corrosion, more solid, double sided and have via's. Also contrast is much better, copper pads on brown are most of the time difficult to see while there are no visual problems with the epoxy green with thinned pad version. August 12, 2019 Reply Minh Tran Is SMD more expensive (component-wise)? The only advantage of THT is power dissipation and quick prototyping. August 17, 2019 Reply Appregator QFN is viewed, once soldered underneath by a very thin Fibre optic, back to a camera. Especially in multiple rows of leads. But nevertheless we'll done on attempting that. 😅 August 18, 2019 Reply Appregator Nice left handed drawing of circuits. The art of engineering requires balanced left brain right brain thinking. Too much of one or none of the other and nothing is accomplished. August 18, 2019 Reply Gergő Dénes Where you learned this hungarian phrase?

That’s is the wrong technical, try to put flux in abundance and came with solder already in iron, will be much beter August 22, 2019 Reply Jose Silva Look for Android o videos, they show you how to do the right way August 22, 2019 Reply Jose Silva Androkavo i mean August 22, 2019 Reply ХАСАН I thing that thermal pad GND of QFN is not happy !

September 4, 2019 Reply ItalianVirgin 4:59 hm yes September 4, 2019 Reply Nassim Koubeissi Excellent soldering techniques When soldering smd ics I first put solder on all 1 side of the target ic and then set the pcb in vertical position then I move the soldering iron tip from top to button that makes the excess heavy tin to fall down to catch them I use a small tool to collect them by suction air pump the final result is cant be distinguished from a machine soldering . September 6, 2019 Reply Jacob Faseler There are many ways to skin a cat, buta) on QFP's you're less likely to overheat the IC if you refrain from flooding the pins with solder, and instead opt for a more precise technique like drag solderingb) You're less likely to murder your μC with static if you use something other than a cotton pad to clean off flux (say a toothbrush, or ESD safe towel)Not saying anything here is wrong, but if you did some of this stuff in a semiconductor manufacturer's lab you'd get written up.

September 15, 2019 Reply Steven Zhu When you use the knife tip (or a slanted screwdriver tip), and never find conical tips useful. You solder SMDs much faster this way September 15, 2019 Reply Tony Fleming You are a great guy – don't listen to losers! I'm subscriber and I watch your videos! Thanks for your videos! September 15, 2019 Reply Norm T You should not teach soldering techniques, rather then using solder wick to do tqfp use a flat tip and turn the board upside down the solder will flow back onto the tip….saves a lot of time must clean your irons tip each time. Pointed tips are useless been designing and soldering for 35 years. Just one rule use Gravity and flux . IE where you want the solder to go it will happily move off a pair of shorted pins if you turn the board upside down the solder will flow back onto the tip.
