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.
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
@@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 👍
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.
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.
You should just get a 10x jeweler’s loupe. That’s what MY 61-year-old eyes would want. Sure, a nice 25X optical comparitor would be nice but the cost...the weight...the space you’d need! 😬😄
@@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.
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
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.

Nice job, soldering. Good use of flux. Nice the way you keep it both clean and fluxed. Lotta skill there. I hate watching videos when they use poor soldering skills. You're excellent.
Nice. Getting a little refresher on some soldering techniques for a possible new job. I've done a lot of aerospace work... some pretty challenging and fun stuff.
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! 😀
I always hold my breath while dragging (yeah, pun intended) But I also held my breath while you were doing it. Anyone who had the same experience ? Wonderfull job 👍
It looks like that chip was fitted by a machine, very good. I learned this many years ago but now my sight is not as good although I do have a steady hand most times which is also important.
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?
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.
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.
very nice technique. May I ask the part number for the Weller tip you are using on the iron. Also what temperature do you have it set too? What solder and flux are you using? One thing is for sure. That's decent solder and not the unleaded clumpy rubbish.
These SOBs make it look so easy. Just put the part down they said. And then run your soldering iron across the leads they said. It'll be fun and easy they said.
Look for a used hot air bonder station (has other names as well) if you're going to do much of this. You can extract, install and reflow precisely. If the connections are under the chip (balls), other methods won't work. also, many of the newer chips will fail prematurely if you heat them past 650 degrees. I'm a tech with 38 years experience.
я бы тоже так умел с такими материалами и паяльником. но у меня советский 60 ваттный паяльник, какие то прутки припоя сантиметровой толщины и камни канифоли вместо жидкого флюса.
When removing smd ic's like these, use a hot air gun. There is less chance of damaging the pads. Also when replacing the ic make sure the pads are completely clean so the pins lay flush against them, or you may have some up in the air not making contact after soldering.

It looks like just a flex pen before the soldering and for cleaning the bridge. After he is most likely using isopropyl alcohol to clean the flux to prevent corrosion in the future
Well, video doesn't explain anything, so I'll do it instead. The key to solder like that is the tip. It has tiny deepening in center which doesn't allow solder to spread out because of Surface Tension. Such tips are very expensive, but you can make it by yourself from common large tip by drilling a tiny hole in center. Keep in mind that such method decreases lifetime of the tip. Solder and flux doesn't make big difference, but I'd recommend low temperature solder to ain't overheat the component.
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.
