Professional Hand Soldering Training - SMT, The Art of Drag Soldering and Fine-Pitch QFP

[@LeftyLuc]

If you continue to drag the tip of the soldering iron until it is fully off of the IC instead of pulling it away from the IC you can prevent bridging from occurring at the last couple pins like it did at 1:22, 2:07, 2:25, 3:14, ect. The trick is to keep moving at a uniform and steady speed until you break contact with the final pin.

[@Kellal_Mohamed]

merci pour le conseil

[@SlideyDK]

im pretty sure he knows what he is doing since he is a certified Master IPC Trainer

[@theralhaljordan7337]

that's probably so he doesn't accidently pull the soldering tip into another component next to the IC, pulling out from the last pins is more controlled

[@JustAlanIsCool]

@@black.iczelion That was my initial thought as well. I'll probably make some mistakes along my repair and actually seeing how to handle this could save me a lot of trouble 👍

[@MrPatdeeee]

@@SlideyDK Whether he is a certified Master IPC Trainer or not, He did it wrong. And that is NOT uncommon by Trainers.

[@brittanychristian4846]

This is so satisfying to watch. I was a welder in the Navy years ago and thought soldering would be too small scale/precision work for me. I think I'll be buying a soldering iron now.

As one who has done similar hundreds of time, I noticed some areas he could improve.

[@paulmoffat9306]

I've hand soldered boards that had SMT parts with pitches as fine as 0.8mm - assembled the first go of prototype boards - all worked properly the first time. One thing that I did, on larger QFPs, was to tack solder the corner pins to keep the part from shifting when soldering the main body. Also works for PLCC components.

Good eye sight is of essence. I'm 61 and can't do anything without glasses nowadays. Looking glasses usually are too weak for me, so I have found a neat solution. A store nearby sells reading glasses for the equivalent of $2. I'm using three glasses that I have taped together, on top of each other. Two +3 and one +2.5, that is around 9. The advantage is cheapness and that the "looking glass" always is directed to the right spot in front of my face. It's almost like having a microscope on the tip of the nose.

@@schautamatic I think you don't know what you're talking about. I own a Bausch and Lomb 10x jeweler loupe, it's fantastic but has very near focal plane distance. You cannot use that to solder unless you want to solder something on the tip of your nose. Lol.

I don't know why but i find this video very relaxing to watch.

[@deadbluesky]

Well this is pretty easy, what he dosent tell is how to pin the ic in place before he start so it wont move when you solder it for those kind of ic, and what kind of tin and flux you use and also the temperature of you iron !! If this is a solder training well you miss too much thing for the beginner... just saying

[@heatherrhodge2588]

exactly what i was just thinking.. that's why i decided to read comments to see what other ppl thought of this

[@peterporkolab2800]

We use two brands of flux: AMtech, or ErSa, they're pretty good. I usually set iron temperature between 360-380 degree Celsius. You have to place the IC manually, after You paste some flux on the surface. This tip is like a spoon, it has a little arc, or curve. Actually, You don't need this special tip, You can do this with a simple soldering tip. Tin: we use the brand "Stannol" diameter=0,8mm, Sn60Pb40. I hope I could help You.

[@stevenstaubach1061]

Ah. A fellow professional. I appreciate your video; I'm teaching th/smd and couldn't make it in person today for my students, so thank you for demonstrating drag and dapple (for corrections) so they have a reference. I would offer this for the final pins: when you see wetting on the final pin, stop and drag down the leads and cut away at 30 degrees out while rolling your reservoir tip under to suck up the excess solder. It's just a sec to hit it again, ik; it's just those little things that make it more satisfying though, imo. You feel the same way too, right?

Nice work! 👍🏼 Back in the 386 Heyday when I worked at Intel, the 25-mil PQFP was being developed. All the pads were printed with solder paste, the PQFP was placed, then IR or vapor phase solder reflow finished the job...sometimes with those annoying solder bridges to deal with. 🤦🏻‍♂️ I noticed that every time you made your solder pass, the last three leads always bridged and needed rework. I wonder if having a fine-thread solder wick at the end of-and and in-line with-your pass would eliminate that bridging tendency. Wouldn’t need any rework that way! 😀

what does he use to clean? (any link to buy?) thanks.

[@SpicyCactus]

[@Visionery1]

That's a damn fine soldering station you have there!

[@windward2818]

My first choice would not be the flat surfaced tip, I would choose a concave tip, either from JBC or PACE (mini-wave), for rework my primary stations are made by PACE and JBC, the concave tips hold more solder volume which ensures you can complete one side of even the largest QFP. I also would use liquid flux to aid in soldering for me in production the PCBs are generally very clean, but the IC packages at times have a noticeable oxidation layer. I have access to production liquid flux of many kinds, RA, RMA, and No Clean which I move to small glass bottles with a small application brush for bench soldering. The liquid brush application work better than the pens because you can apply the volume you need quickly and easily. Pens are handy, but very expensive compared to a small lab grade glass brush application bottle, but obviously you need to have access to production liquid flux which is not always possible. For example, if purchased from Kester, the minimum size is one gallon. In production it is purchased by the barrel and for emergencies a few 5 gallon jugs in case the barrel is contaminated or expired as judged by the production chief engineer. If you use the proper liquid flux and a concave tip, you can easily complete one side of a large QFP with no solder bridges. Also, for rework I generally have the option to use leaded eutectic solders depending on the subassembly. The most difficult liquid flux to get for me seems to be No Clean or Organic, which many times in production requires no end of line hand work to complete the assembly.

[@paranoidzkitszo]

At the beginning the iron is visibly displayed with the temp over 600...i don't like to assume- though very hot if celcious...so, is that F.? So, approx 350/60 c? Not...675c? But, 675F?

The last few pins get bridges, but that is to be expected because you do not want to slide the soldering iron onto the pcb board which would leave an ugly mark. doing it like this, the soldering looks like it was done by machine, very clean.

[@bikramadityaguria2340]
