wyunway Solder Wire 63/37 Tin/Lead with Flux Rosin Core for Electrical Soldering weight 1Lb(450g) 0.8mm(0.032)

Its great for low temp wire connections. will purchase again.

PLEASE NOTE: There are multiple items / sizes available from this listing. Amazon places all reviews from these multiple items in this one place. The item that I received and am reviewing is wyunway Solder Wire 63/37 Tin/Lead with Flux Rosin Core 0.8mm (0.032 inch) For 25 years my job was to sit at an electronics repair bench and make broken equipment work again. I’ve used a fair amount of solder during my lifetime as I still do some repair work today. I’ve noticed that my stock of heavier gauge general electronics solder was getting depleted. How nice to find this .032 solder just when I needed it. Now to test it and see how well it works. And the answer is: it works very well indeed. I tinned 2 wires initially for part of my testing. The pictures are below. The grey insulated wire with the silver looking strands always tins well as it did with this solder. The brown lamp cord has been stripped for the past few years so air has gotten to it and tarnished it slightly. This is a more difficult test. If the rosin flux is a good quality, even this slightly tarnished wire should tin properly. And indeed it did. I soldered some components on a circuit board and also tried some solder wicking braid on the parts I just soldered. Everything worked just fine. I’m quite pleased with this solder and can highly recommend it.

The real beauty of this product is that it has a flux-rosin core so after you sand and clean the joint there is no need for additional flux. Less mess and fumes and really great soldered joints. If you do much soldering, then I would recommend that you try this brand. I think that you will like it!

There doesn’t seem to be a lot of difference between various solders for electrical connections. From the picture on Amazon, it is hard to visualize its exact size. This brand is very thin. (See the photo comparing it to plumbing solder for copper pipes.) This makes it easy to solder small parts together. It is ideal for attaching supply wires to LED lighting strips or for fixing or replacing parts on a printed circuit board. I tried it out and experienced no unexpected problems. It contains lead so it isn’t RoHS compliant, and you should be sure to wash your hands after using it.

I make kits occasionally and more often solder connectors on cables as I do experiments and just in general, play radio! This solder seems to work just fine for my needs that Ive thrown at it.

Quality solder that is smooth and even. Melts effortlessly, and doesnt smoke excessively. Not the best deal on value, but a good product.

The solder flows well and provides a solid connection. It does what solder is supposed to do.

Occasionally, I tinker with various electronics (CNC, 3D printers, etc.) and need to do some soldering. This flux rosin core solder from wyunway is fairly thin at 0.8mm, but it works great for small electronics. It tins very well and flows nicely. This is very good solder.

Great. Flux core and it flows great. Im using this mostly on through hole and SMT hobbyist electronics, probably too big for smaller components. Melts a flows well. Arrived well packaged, bare on spool

Its exactly what I needed
