I really like this lightweight kindle & the fact that the color is on both back & front - ru-vid.comUgkxCgPI5O2AtmcHq9SJhgsCGbpAzJAJfrJp I just wish that Amazon would put the on/off button on the TOP of the kindle so I didn't keep turning it off while trying to hold on to it. And WTF were they thinking when the changed the size of the charging port? I own 4 kindles and now 3 work off of the same mini charger, the same one as my phone, but this new one is a different size so I have to have its "special" charger with me or a second kindle in case the battery goes flat.
I wasn't dropping my jaw until I saw the 160-pin QFP being soldered with an iron. Amazing work and technique you have. This gives me higher confidence to try new soldering methods (I can already do TQFP-32 and SOIC-24 all day), and also to be less fearful of higher-pin-count devices in my designs.
Wow, masterful. I saw this on reccommended by accident after viewing another soldering video, and yours is so clear and full of detail. Thanks! I have a painfully small port break I have to learn soldering for
Absolutely outstanding. Lots of 10-minute videos consists of the uploader rambling on and on about how to solder. Your video jumps straight to the point and shows several different ways to do it in just 3 minutes. Great job. Liked and subscribed!
Leave it up to the guys at IPC to make such outstanding videos. Had my IPC training a month ago and even though I was no stranger to SMD soldering already, the videos were of outstanding quality to show exactly what was going on while soldering. Fortunately, they did not have any music under it, just good voice-overs ;)
Holy crap, your skills are amazing! I've been soldering for a while now, I thought I was pretty good but I can't even hold a candle to you! Fantastic video, thank you for sharing!
I have been soldering for a very long time and this is one of the most sensible videos on this topic - usually everyone has everything burns, turns black, solders for minutes )))
You, sir, are a true master of your trade; that is clear! I am fascinated by the different multi-lead techniques. That bevel tip seems critical for any kind of production work...
+71dembones - The bevel tip or hoof tip as I call it is ideal for multi-lead and drag soldering. I prefer the large hoof any day or a good miniwave tip with the recessed well to hold a little solder. The hoof wets so well due to increased surface area which transfers heat much faster. The liquidous solder always follows the heat source. Yes, a bevel is important for production if the operators are properly trained in their use.
Great video. I start a new job Monday as an electronics tech after being out of it for roughly 8 years. Your video gives me some confidence that I can get back to form. On the other hand, watching Bob Ross also makes me think I can paint... so we will see.
respect sir, respect! I'm from Greece and you help me a lot with your tip. Actually you make it look so easy the soldering with your stable hand. So stable tha you make the viewer to feel that it can do this so easy as you. You are the best and we are waiting for new videos.
Thanks for posting this video and these other tutorials. Looks like nicely skillful and inspiringly precise soldering compared to most of the soldering videos I have seen on youtube.
Cold solder joints are the result of oxidation, contaminants and or insufficient heat. Cold solder joints are not part of my game, so to speak. I have not had a cold joint in at least 15-20 years. Students I train do not experience cold joints as I teach them how to prevent them. Those who solder "cold" are undeveloped in their training. I also never use a solder wick on leads. I pull solder bridges with ease, just as anyone can if they understand the process.
Your video is outstanding! I tried soldering SMD parts with a similar tip and according to your explanation and it really works a treat. Thanks, and keep up the good work.
Truly amazing. I wish I had even half of this skill, it would have saved my Philips TV mainboard which I ruined, trying to replace a blown microchip, even with plenty of spares I still messed it up badly. Eventually damaged the board with so many poor attempts, and have ordered a replacement board. Frustrating!!! Great video and Best of the Best skills. Cheers!!
you definitely inspire me and i have bought my equipement as you suggested plus i had to get some more smaller tips, because i do rework on cell phone boards where CF3 for example is too big. I was able to drag solder with the smaller tip and i love the results. Thanks for the video!
After watching this amazing soldering techniques I learned how to solder this kind of smd IC's similar to this video with a very cheap soldering Iron, after I learned how to do it similar to this video I figured out that nothing is impossible, thanks
Thanks for sharing the video - you make it look easy. :) I've been looking around for good QFP technique, but I'm a little confused on this. I'm assuming the blue tip tube is solder paste and the yellow tube is flux? If so, I'm having a hard time figuring out where all the solder comes from when you do the swipe at 2:05 :) May I ask what solder/flux you use? The stuff I've used for SOICs seems to have too much surface tension for QFP work - or maybe I just need better flux application.
Excellent work-Beautiful accuracy. I see you recommended the Weller WESD51. It looks like great low-to-middle end unit. I can't seem to figure out what the exact model # is of the hoof-type tips, similar to the ones you use in this video. I know you have said Weller calls them "single flats", but I can't seem to find any that match yous. Can you recommend a good tip for the WESD51 that I can use on a 100-TQFP chip? Would it be their ETDD? How about for the Hakko you recommend? Thanks!
Thank you for excellent video. It explains quite a lot, especially this thing about flat surface on the tip. Personally I am using Weller tools and needle-like tip No 7 for this but now I will try your technique, it is so elegant.
Damn, this is such a seamless tutorial that could have taken far more time to master even though I have intermediate experience. And here I thought that this was hard, but these techniques done by this person is so precise that I cannot believe it. Heck, now I'm getting a little jealous.
I looked this guy up. He 15 minutes away. He came and visited my shop, showed me a thing or two....we became friends. All I gotta say is thatTechnique and practice is what this takes to make happen. Hakko is top of the line, but even with those 8 dollar radioshack irons, you can do close to, if not just as well as this video. I haven't talked to John in a couple years but if anyone wants to chat about his methods or wants some tips (advice, not equipement), let me know. I am more than happy to help. I have a camera on my microscope, so that helps.
This is one of the most satisfying videos I've ever seen. Those are some beautiful joints. Your experience really shows with this. I'm currently learning microsoldering by fixing things like broken connectors and charge ports on phones and tablets. Just successfully desoldered a broken micro USB off of a tablet and cleaned the pads. Can't wait to try soldering the new one on. I think I'll get one of those bevel tips. They look really useful. Edit Also if you don't mind my asking, when it comes to desoldering SMD components (like charge ports, connectors, and ICs) I've seen some different techniques. I personally used flux and some fine solder wick to remove most of the solder then used an SMD reflow station to lightly heat it up until it gave way with some tweezers. I've also seen other people use flux and heat only. I'm assuming the technique really depends on the number of leads? Or is one better than the other?
Great and one of best videos ever. Thank you. John, can you show me link to buy or full product name of past that you applying on 1:40 or 1:48 ? Thank You
Hello John! Great video! Do you have to/ is it desirable to aplie Flux to the joint even if you are using rosin core solder which has a flux core? If i would start to solder should i clean the surface i want to solder on before i begin with isopropyl alcohol??
With a little practice, it's not too difficult. The key is having the right soldering iron tip and enough flux (personal preference is a bevel tip with an indent "solder cup"). Apply a generous amount of flux to both the component leads and pads, and drag away. If you get a bridge, it usually means you didn't apply enough flux or you have insufficient heat (either temp is set too low or you have something dissipating too much heat like a massive ground plane). Also, not all fluxes are created equal - some are more aggressive (active) than others, and more aggressive flux can be beneficial if you're working with boards or components that are slightly oxidized. I like water soluble flux, because it's fairly aggressive and it cleans up so easily compared to rosin. Water soluble is also great for Rohs (lead-free), and makes nice shiny solder joints after washing.
Flux ingredients also matters. Same for solder pastes. Cup tip indeed is great for QFP and similar multi-pin packages. With proper flux and solder it does wonders.
Brilliant soldering demo. After 12 years still actual. Actually not so hard to repeat, however proper solder, proper flux (especially), proper soldering iron tip and proper temperature are very important here. More or less steady hands are also prefered :)
Hi again John. Thanks for the advice on tip part#s. I have found a mid-line Hakko unit, the 936. It is analog, and uses different tips than the 951. Do you have any experience with it? Thanks.
And i thought i was good at soldering, eons behind. Thx for the perfect video presentation mate, and top choice on background music. I really did`nt want the video to end.
simply incredible soldering skills. I am almost suspicious that some kind of time lapse camera shot trickery, or some video editing trick was done to prepare this video. The skills displayed in soldering were out of this world provided they were captured by the camera in real time.
ManjaroJam Greetings. I use no time lapse or trickery. You are viewing real time. Thought you might enjoy this other one of mine. My best to you. vimeo.com/26348524
What the (approximate) temperature of the tip? I have a new Pace ST25 soldering station that boasts a tip temperature control. I want put it to the test.
Absolutely beautiful soldering...... This Wallmart soldering iron just isn't doing the job for me....I felt like crying and laughing while watching your video at how easy you make this look. Thankyou for the post.
@@therealb888 the tips oxidise too fast on those cheap non temp controlled irons as they get very hot (around 400C+) thus allowing tips to be oxidised very quick. Add to that novice techniques and no care for tips and yeah. Best way to use those is to periodically turn on and off those irons so they maintain a workable temp but not get too hot
I remember when involved with electronic manufacturing that we used guides that Martin Marietta put out many years ago. It was one of those things where a company developed for in-house use, and then decided to sell it (I found them and it at a "NEPCON" West show in California back when they still held those.) Each practice (soldering, crimping, wire prep, whatever) included four photographs. In descending order they were called something like "Ideal, Acceptable, Minimum Acceptable, Unacceptable". They made the goal clear, but left a little room for practicality. The examples in this video are certainly in the "Ideal" category. Especially the soldered lead in the through hole example. It is supposed to look wetted up the lead, and be cut above that point.
I have been soldering frequently since I was 9, (1958) and I feel embarrassed to see how far I have to go. Heck, I thought I was pretty good....I bow to the Master:>)
More of a cheater then a master. If I had tons of money I could order a new quality PCBs from China and take my time practicing these soldering methods for fun.
Great video but I have one question. When you are cleaning the flux off, you seem to use the same brush for the initial application of alcohol and also for pushing the kimwipe onto the part. Is this necessary - does the brush need to be wet? I would have thought you'd want the brush to be dry on the second part of the cleaning process. Can you please explain this?
Very amazing!!!! Bravo sir you are a master at the craft! I am just learning SMT is using solder paste a good way to start? You should post videos that have tips for beginners on SMT soldering! Again very good job! Jeremy
The demo was done with an SOIC/TQFP format chip, which is VERY easy to solder. Try TSSOP format! TSSOP's pitch is very small, less than 0.5mm! Excellent video. Very professionally done.
+unebonnevie - TSSOP is very easy to solder with ultra fine pitch if you use a micro hoof tip and proper technique. My technique is almost identical to this guys with the exception that I use a trick or two making it much more efficient. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-tKl23o70iqM.html. Here is one of a 15 mil ultra fine pitch TQFP I did recently. Believe one thing my friend, if it can be soldered, I will solder it, I assure you. It will also be aerospace quality. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-6PB0u8irn-4.html
