@electronicsoverhaul 4 года назад

Chip Quik SMD291 is great for soldering on ICs. It has a low viscosity, a greasy consistency. SMD4300TF10 is good for whatever else. Amtech does leave a sticky residue I don't like. When you heat the flux, it’s very transparent making it easy to see what you're doing. These are good for phones and small SMD work. I think rosin-based flux is fine for just about everything but can be harder to see for the small stuff with it's yellow coloring or becoming browner with heat. Rosin doesn't evaporate and smoke as quickly as Amtech. You can heat rosin to 500C, and it won't evaporate. It can turn darker as it heats up with use as you slide the solder iron around it more. Use what you like for whatever applications.

@Galactus314 2 года назад

These fluxes were all tested on surface mount components, using PCBs with no vias. When heated, they all turn to liquid, and near by vias could drain it away. The liquid fluxes you can clearly see evaporating along the right edge at 6:20 and 6:50 respectively. They seems to have very limited uses. As someone else commented, I'm curious how the SRA No Clean Tacky Flux could handle those condtions. Also, I do a fair amount of through-hole soldering, and literally all of these fluxes are simply too thin for that. So I'm seeing a good case for another video. Boards with vias, the SRA flux, and something for the THT crowd (zinc chloride, as well as non-ZCl). Thanks!

@OriginalMergatroid 2 года назад

Excellent video. I have been using MG Chemicals flux pen that is a liquid flux. This is the stuff Nintendo recommended to us about two decades ago. I never did like it much and it was constantly bridging, especially on the last few pins. If course, those ships had over 100 pins so the gap between the pins was smaller. I just ordered some MG No Clean solder paste before coming across your video. I am happy it performed well in your tests. I would love to see some examples of how to resolder a BGA chip using this flux.

@danfreeman8225 3 года назад

Outstanding vid! Great layout, info and timing. Also excellent layout of links! I might suggest a couple things that might help. It could be handy to know the details of the solder you used and the temp (if you had a way to measure) and having video times next to the list in the description. Thanks so much, it really helped!

@What_I_Make 5 лет назад

Your analogy on the fluid is spot on. As a part of the soldering I carried out at work, we looked at this and using the microscope could see the heat from the soldering iron directly burning off or evaporating the adjacent flux. I do have a concern with the thin consistency. Originally and at home, I use a thick paste and found, and in both cases, they last a very long time. With the thinner paste, it is tough to administer by hand, and because the density is lower gets used up very quickly. This may be my method, but there was a definite consumption at work between the two.

@KimoKimochii Год назад

by the flux lasting long does it become so thick it’s unusable? i find after a few minutes the flux gets so dried and thick on the board i need it clean it off and reapply

The yellow tub of Bangood flux is really nice, and can ship from USA. The only down side to it, is that a brand new one weighs 113 grams including the container. So it's maybe 100g, not the 150g they sell it as.

I'm just starting with SMD soldering (or planning to do so for long) and this was extremely useful information. The brand/price overlays over the different options and again on the results was brilliant. So easy to compare. Talking pace and speech clarity also spot on. Great work, thank you! Two things I would have liked to hear (or missed): 1) what type of solder was used, 2) is the shelf life of the flux jars longer than on the ones that come in a tube? With the little time I have, it might be weeks or a month between I solder anything requiring flux. It's quite frustrating as the manufacturers state the shelf life to be only months. I've seen tips of reactivating old flux with IPA (maybe it was also on your channel?) but I've yet to try it.

Although an old video, it is really useful. I used to use the amtech fake flux for years and recently tried the CIF. The CIF leaves a sticky residue that in my opinion needs to be cleaned. Fortunately it is easy to clean.

@Zellonous 2 месяца назад

@jamesdavies686 3 года назад

Watching this again it's interesting how the solder climbs the component leg on some but not other fluxes, even if the flux did well with no bridges.

@marcotestarmata 5 лет назад

IMHO the genuine Amtech really shine when used with an hot air gun. It really make the difference, it stays there active for a long time but you really need good ventilation or a real fume extractor, it is very smoky. The fake Amtech's residue are much harder to remove and they spread wider on the board. It is cheap but i won't buy it again. For general soldering i like to use the liquid TOPNIK RF800 in a squeeze bottle with a fine gauge needle. I work mostly with beefy through hole components. RF800's residue are really easy to remove with IPA and the flux works very well and it is not very smoky. Liquid flux are good just with a soldering iron. With hot air you need a gel flux, and the Amtech is the the best flux i've ever used. Just my two cents.

@sdgelectronics 5 лет назад

I'm going to do a test with hot air shortly - firstly with the PCB used in this video, but it sounds like it would be worth getting another test board with some large ICs and a ground plane on it. Thanks

@Slavolko 4 года назад

Louis Rossmann swears by genuine Amtech flux for all the work he does. In fact, he buys and re-sells them because he trusts them that much and wants others to be able to reliably source the genuine parts.

@pr0xZen 4 года назад

@@Slavolko It's fair to promote it as it's genuinely great for its appropriate usecases. But its also really expensive, at least for those who do not generate any revenue on soldering work. And for many of those without a national/regional distributor, as international shipping and potential import taxes can make the total price really brutal. I need to point out that the sentiment pushed by Louis about the _process of buying_ Amtech flux is a horrible ordeal involving faxing orders etc, is either false or long outdated. You can just order it online from Amtechdirect.com . They're one of the few official distributors for Iventec (Amtech is a product lineup, Iventec is the company), and as such they keep shipment-ready stock of pretty much the whole Amtech lineup. So if you need _anything else_ from the Amtech lineup, these guys are great to have around, as you don't need to worry about getting fake products. That said - unless you want 10cc quanitites, or large tubs, buying no clean 559V2 tacky flux from Rossmanngroup is not a bad idea at all if the shipping etc works for you. Because the 30cc units Rossmann Group sell, are $16. From Amtechdirect they're $27.

@Hackvlog 5 лет назад

I used to use some other liquid flux, but can't remember which brand it was. It had same properties as the ones you tested: More flux was needed for larger IC's. It either boiled away or spread so much, there wasn't enough flux around the last pins. Practice will make it better, but main cause is the properties of the flux. In my opinion liquid flux is very easy and quick to apply. I'll add TK83 to my shopping list, thanks to your video! Well done with the comparison!

@sdgelectronics 5 лет назад

I think the liquid fluxes just aren't as suited to this particular style of soldering. It would be great for BGA style work as the liquid is drawn into gaps easily. It also cleaned off very easily. Thanks

Zinc chloride containing fluxes (such as the weller one) are not suitable for electronic components soldering, they are mostly for plumbing since ZnCl2 is pretty corosive and has to be removed after soldering. Moreover, ZnCl2 is extremely dangerous for a human: it's a skin irritant and its fumes cause lungs diseases.

Hi, awesome video! I'm from Latin America and I've seen many weird fluxes. Some can ruin a board, like when liquid amber flux dripped on a hard drive and dissolved the copper. Sadly, I didn't see it for a month or two, so it was too late. I suggest trying a good board and switching pads between isolated and connected ones. This can act as a heatsink, change the performance, and show more differences between the fluxes.

I often use a flux pen, it looks like a felt tip.... you push down on the tip and it soaks the tip....then it's applied to the joint to be soldered, however, for me it doesn't seem to work as well as the paste type fluxes, but it does the job....the syringe type fluxes can be tricky since they tend to glob it out per sae. But, IMO....most fluxes work just as well as the next, alot has to do with soldering techniques as well.

@sammccormick1 Год назад

I got some of the Chinese flux, which is very sticky and seems to be based on a type of paraffin wax. I mixed it with some (15% ish) mineral oil (corn oil in my case) and achieved a soft butter-like consistency that allows it to be loaded into a syringe, It performed the same as in the video however it was much easier to handle coming from a syringe. I used a 1mm metal tip on the syringe. Cost for 10 cc was approx $0.85 (115cc of flux cost $11 inc delivery). I am sure other types of mineral oil will produce similar results.

@rhalfik 22 дня назад

I use topnik mostly because it's a local brand, but I can tell that gel works better than liquids. They have their use for sure, but they're displaced too quickly with heat. Gel is more persistent.

@tristankordek 4 года назад

There was a problem when soldering with TK83 because the maximum application temperature is 280 degrees Celsius I suspect that you overheated it and began to boil, after adding another portion of flux, it just cooled down and soldering went fantastic again. Because I am Polish and TK83 and LP-1 are Polish fluxes, I know a bit more about them, if I remember correctly, we used the AG-5 flux for soldering at higher temperatures (up to 400). We have used them for many years and in general AG TermoPasty products are very popular in our country (they are cheap but very good). By the way, the Polish word "Topnik" means Flux from the Polish word Topić - melt.

Something I learned from the school of hard knocks was to use the pitch from a pine, fur, etc. tree. It's also called resin. And it's free. Also to anyone using an acid resin on electronics DON'T! It'll eat the copper wire and the PCB board. (Friend did a repair on a board in his stereo wire acid core solder and it worked for awhile but eventually ate the board to the point he had to replace the board.)

Thank you. Very interesting video. I would like you to expand your video to test a couple of other characteristics. Effectiveness on oxidised components and also even more important for me how fast the flux burns off. Especially important for hot air when a lot of times we have the heat on for a while. I believe the genuine amtech is what is supposed to set it apart from the others in this regard as it stays aroind for longer. Would be great to see some sort of a test for it. Thanks again.

I'll work out a video with the same PCB, maybe removing and re-applying the IC with hot air. Thanks :)

@@sdgelectronics your current pcb is probably not a good example. You need those quad pack chips that have a big ground plane on bottom. Your current chip and pcb would be easy to remove with hot air. You need to simulate a large ground plane fighting off yoir heat gun if i am making sense

@@sdgelectronics did you ever make the hot air station video? Great vids btw

Weller flux made me hardly detectable short-circuits, when applied to IC's. It wasn't detectable with multimeter, but only with infrared camera, when after a while, near VCC and GND heat started to abnormally build up. So be careful with it.

that weller flux reminds me of a blue tin solder grease made by stannol gmbh called lotfett, even comes with the same warning (contains zinc chloride) but the blue tin stuff have warning against using them for electronic or electrical soldering

I wonder if it's a Fluxite-type paste, with metal particles, meant to solder sheet metal and large power cables (not electronics components).

Now would like to see proper board cleaning from flux residue tutorial :) Although PRF 6-68 cleaner liquid with cotton swabs do the thing just fine, I'm curious about how to get flux residue out of bottom of ICs. What I noticed - JBC C245931 minispoon tip still do the job on QFP packages very good. BST-223 paste is not so good for small QFP ICs and USB sockets. Once fried few traces on board and one microUSB socket because used BST-223 and pins instantly got swamped under solder. Damaged bothsoccket and traces on PCB while struggled with excess solder cleanup.
