Essmetuin No Clean Soldering Flux Paste(4Pack), Solder Flux For Electronics Soldering, Tin soldering, Lead-Free Rosin Soldering Flux For Circuit Boards and Copper Electrical Wire

Real human review here!!! This Flux is pretty fantastic, considering the price. I typically use Amtech ot Stirri, which are both world class, but this Essmetuin will get the job done, almost, as good, for a fraction of the price. I spent some time doing coin cell battery replacement on some of my Super Nintendo games and this Flux was a breeze to work with. It keeps the solder flowing and has great wetting action. All of my joints came out solid and nice and shiny. It didn't smell bad or smoke any more than the better Flux brands that I've used. It also didn't caramelize and harden after use, which I've definitely had happen with some other brands. It is a tacky Flux, but I wouldn't call it overly sticky and it's not ridiculously thick. When dispensing it from the syringe, I would say it has the consistency of something like pudding. But, it obviously flows out of the syringe nice and smooth. And although this is a no-clean Flux, you will probably want to clean it off your PCB if that's what you're working with. Some Q-Tips or a toothbrush and isopropyl alcohol will make short work of any leftover residue. But, if you really don't care, you don't have to clean it up. It won't hurt anything. This Flux isn't any messier or harder to clean than the other brands I've used. Every tacky Flux is going to require some clean-up if you want everything to be, not a bit sticky, when you're finished. For the price, I don't think you can beat this quantity. If you wanted 4 syringes of Amtech or Stirri, you're going to pay 3-4x the price. And those brands are awesome, but the Essmetuin is probably (almost) as good, for 99% of projects.

I recently purchased the Essmetuin No Clean Soldering Flux Paste (4Pack) for various electronics soldering projects, and I am thoroughly impressed with its performance. This solder flux is a game-changer, especially for those who engage in tin soldering and work on circuit boards and copper electrical wires. The most striking aspect of this product is its "no clean" feature. It significantly simplifies the soldering process by eliminating the need for post-soldering cleanup. This not only saves time but also ensures that the soldered components maintain a neat and professional appearance. The consistency and quality of the flux paste are excellent. It adheres well to soldering surfaces, providing a smooth and even application that greatly enhances the soldering process. This consistent quality is vital for precision work on circuit boards and electrical connections, where accuracy and reliability are paramount. Another commendable aspect is that the Essmetuin flux is lead-free. This makes it an environmentally friendly choice and aligns with health and safety standards, which is increasingly important in electronics work. Each pack in the 4-pack set is a testament to the thoughtfulness of packaging. The containers are well-sealed, ensuring the flux remains fresh and free from contamination. This attention to detail in packaging reflects the overall quality and professionalism of Essmetuin as a brand. In conclusion, the Essmetuin No Clean Soldering Flux Paste is an outstanding product for anyone involved in electronics soldering. Its ease of use, high quality, and environmentally friendly composition make it a top choice for both hobbyists and professionals. I highly recommend this product for your soldering needs; it truly enhances the efficiency and quality of soldering work.

This flux paste is my favorite from now on. I've been using Kester 186 liquid and the pen type flux for point-to-point and through hole soldering but when I had a SMD soldering project I thought I'd give Essmetuin flux paste a try. Glad I did, works great on SMD's, point-to point and through hole soldering, a lot less messy and pinpoint accuracy. Also tinning wires has never been so easy with this flux paste. I ordered two more of them. Just use a fume extractor.

Before I was using flux paste from a can. This item is Easy to use with less clean up. Works as advertised.

Very sticky, pretty thick. No offensive odor. Quality as a flux in general is fine. It's just very tacky and hard to fully clean.

Works as expected

doe its job well, like the tips, getting ready to ord3r more soon.

This stuff is amazing, size prefect, holds more than it looks, easy to use and hold, can be used on anything that needs soldered

ممتاز

Decided to try this brand out and I’m very impressed with what I found. I’ve always stuck to the big names for soldering equipment but decided to give this brand a go. Absolutely love my decision, the quality is there and the product itself works great. I’ve been using it for over a month now and I’m getting perfect solder joints and the flux is performing exactly how I’d expect. I love the choice of two needle lengths and I also love how the syringe comes with the plunger removed. So many times I’ve experienced mishaps where the plunger is depressed and my flux goes everywhere before I receive it. Them shipping it disassembled with the plunger removed completely prevents this. Absolutely will be repurchasing, came in such a convenient and easy to use form factor. The syringe fit my hand very well

Um... it's flux. It works like flux. Having two sizes of tips is nice I guess, if I decide to start soldering like Louis Rossman. For the record, despite what the description says, don't use this for pipes, electronics flux and plumbing flux are not the same thing, and this is definitely soldering flux. Trust me, I do both.

Nice Product and Worked as intended

Awesome stuff
