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

This 63/37 tin/lead 0.8 mm diameter solder flows and works perfectly. The rosin core is exactly what is needed to prepare electrical surfaces for solder to bond to them. This is the exact product needed for minor repairs of replacing components broken from circuit boards and similar projects.

What can I say... its rosin core solder! Good stuff particularly for wiring and anything that might need a little flex (wiring harnesses, etc.). Good value for the dollar!

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.

Its exactly what I needed

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

High-quality rosin with built-in flux to set fast and stick well. If you solder much, you know how vital a good solder is to work with. Its just as good as more expensive high-grade rosin.

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.

Great product perfect for all the small soldering jobs because it has rosin in it one less step and being tin lead it requires less heat to solder than silver solder.

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.

I got this solder to use with my electronics and ham radio projects. When I used it, I liked that it melted easily and flowed smoothly. It’s solder, so there isn’t much else to say, but it does the job and seems to be fine. One thing to keep in mind is that solder that contains lead works better but should never be used where it will come in contact with food or drinking water. So, this product is great for electronics but should not be used for plumbing purposes.
