Questions & Answers
Flux cleans the metal surface to which a solder bond is to be formed. Soldering effectively necessitates a "wetting" action, which results in the formation of a metal alloy at the joint. You will not create a metal alloy if there are oxides and dust on the contact surface you are soldering to (such as a copper bit on a pcb), and the bond can be scraped off with a razer blade. Because the solder and two metal components you're connecting are now chemically bonded as an alloy, you shouldn't be able to easily scrape it off if you use flux correctly.
The following is taken from the Technical Data Sheet of MG Chemicals: br>2 year shelf life br>Storage Temperature Limits 18 to 27 °C 65 to 80 °Fbr>Store at room temperature and keep out of direct sunlight.
Because this is just flux, you'll also need solder wire. You can also use solder paste, which contains both metal and flux in a single syringe.
You just have to use it for a while; I had the same issue because the ring fit so poorly into the back, but once you get the plunger further in, it's a lot easier to use. It's a dreadful design flaw, I agree!

Because Amtech was recommended, but it was twice the price, I chose this "best seller" and "favorite" instead. After all, isn't flux just that? br>br>This is incorrect. Before you can even get your iron or heat gun out, this stuff has evaporated. The small amount of flux that does remain is insufficient to aid the soldering process. br>br>Getting the thick goop through the needle requires superhuman strength, and once it begins to flow, you must pull the plunger back to ensure it does not continue to flow. To summarize, this product necessitates the use of two hands, a significant amount of strength, and fails to perform as intended. Useless. br>br>I've just placed an order for the recommended brand, and I've already learned my lesson.
I bought it because it showed a needle and I needed it for precise application, so it wasn't packaged as shown in the photos. There was no needle included with this syringe. I will not buy from this seller again, and I will not trust any other listings.
My soldering skills were lacking when I first started repairing SMD electronics. I saw a guy using this paste and decided to give it a try after trying a cheap flux pen that seemed to be mostly alcohol. It's made all the difference in the world. br>br> When applied, the paste is opaque and remains in place. When heated, it becomes clear and melts, allowing it to flow precisely where it is needed. Although it does not appear to be as smoky as most solder wire flux, fumes do exist, and a fume extractor is extremely useful. When soldering, the solder flows much better, resulting in gleaming joints with excellent tie-in. ins. The only thing I don't like about it is that it takes a lot of effort to squeeze the paste out of the syringe, and then it takes a slight back pull to keep it from coming out too much. br>br> It's also worth noting that a "no clean" flux simply means that any flux left on the board after soldering won't harm the circuit if left alone; it doesn't imply that it will evaporate without leaving a trace. A good clean up with 99% alcohol and an acid brush followed by dabbinh the board dry with a lint free cloth takes care of clean up.
This flux has a flaw in it. I'm not sure if it's a batch problem or simply bad luck. Within the flux, there are crystallized flux balls or some sort of contaminant. I'm working with BGAs and I can't use this flux because the contaminants don't melt with heat and won't allow the BGA to properly mount on the circuit board; therefore, this flux is now useless to me. To demonstrate, I smeared it on my finger. Is this something you've ever seen?.
This is something I've ordered before and it always works out well. This item was delivered without a cap on the tube's end, and it had leaked all over the place. Furthermore, it was not packaged in the standard plastic. Order with caution; you do so at your own peril. For the same price, they used to offer a two-tube package, so you're not getting what you used to get for your money. EDIT: br>br> I just added a picture to an older tube of theirs, and you're not getting nearly as much solder flux as you are. The old tube weighed ten grams, while the new tube weighed nine. It's an 8 on the scale, but it's a 9 on the scale. DO NOT BUY if the weight is 6 grams and the tube diameter is different.
It takes a lot of force to get the paste to start coming out of the tube, making it difficult to use. Then there's the part that's really bothering me. I needed to clean the joints right away. Guitar pots were the focus of the project. To avoid scratching the guitar, I snatched a towel and placed it on the worktable. I tinned the pots after applying flux to the backs of them. Allow them to cool before placing them on the towel to absorb any excess moisture. Later, it was discovered that the joints were literally stuck together! The backs of the pots would stick to my finger if I put my finger on them. Lint, towel fuzz, and cat hair were stuck to everything not too far down the road. My hemostats, the joints. the tips of my fingers It was a shambles, so cleaning may not be necessary from an acidic standpoint, but it does need to be cleaned off. I used alcohol to remove it, but it didn't work very well, and the sticky residue remains. Apart from those issues, it appears to function well as a flux.
Fluxes that are free of contaminants are available. This is something I really enjoy. I use a variety of fluxes, as do most people. Prior to this, my go-to Chipquik SMD291 was the name of the product. Although there isn't much of a difference between the two, I prefer the MG Chemicals version. It's a lot easier to clean up bridges, solder blobs, and other messes. br>br>However, I would recommend dispensing from this tube into a smaller (3-inch) container. syringe (5 cc) This simplifies application because you can apply more pressure with less effort than with the large syringe that comes with it. My preferred method is to use a short length of wire to connect the syringe tips (0. Silicone tube (5" in diameter). There is very little air entrapment, and there is no mess! Overall, I would recommend this book. br>br>.
This was my favorite flux paste for years, and the most recent update to the product makes no sense. The plunger, main body, and dispensing tip are all included in the package. I thought it was fantastic that there would be no more shipping mishaps. br>br>The issue is that the plunger cannot be mounted to the body in any way because of the design change. I figured it must be a flaw, so I emailed MG Chemicals right away. Here's what I got: "Yes, the packing has changed, and the plunger no longer attaches or snaps into the back piston. " The plunger's sole purpose is to force the product out. "br>br>You are expected to use the plunger to simply push flux out with no way of releasing pressure, resulting in a mess. To make matters worse, you now have to keep track of the main body and the plunger every time you use this product. br>br>I will now be looking for a replacement for this product.
