Kester 24-6337-8800 50 Activated Rosin Cored Wire Solder Roll, 245 No-Clean, 63/37 Alloy, 0.031" Diameter

Nice, large one-pound spool of thin, rosin-core, traditional lead-tin-alloy solder. This traditional alloy melts at a lower temperature than the newer lead-free solders and so is easier to use, which can make it easier to solder sensitive components and equipment without damaging them (lower temp, less heat).Kester is a well known and regarded name brand that has been around for a long time. Excellent choice for general soldering.

World's best solder. Don't buy the random brands, this stuff is the best! I use it heavily for repairing vintage tube amplifiers. Flows great, sticks wonderfully.

600F and it's perfectly flowing, not super smokey, and cools nice and shiny. Couldn't ask for better solder. I won't settle for less again.

This has been an excellentExcellent value for the amount that you getWorks well I’ve never had an issueA great thickness for minor board repair

Awesome product. I have worked with Kester my entire professional life as electromechanical engineer 35+ years and this company never lets me down. This is a new item I used and I love it the flow rate is so quick the components being soldered do not even have a chance to get to warm to handle at least for me. The joints look better than mechanical hot flow machines that mass produce pcb's and other items. Always a shiny well even flow no gaps the pads on the boards do not get hot to remove the glue so they stay in place. I soldered some really grody nasty joints on things today and the core worked great cleaning the area so solder flowed evenly and smoothly. Once again KESTER ou knocked it out of the park I will always buy this product and the company that I purchased it from well I had it the next day I think maybe day after I ordered it but that was awesomely quick KUDOS to you. You have my business from now on. I made on a personal level some SMD RGB 5050, 0603, 2835 LED'S to hook up wire 30 Gauge and this solder was the bomb the leds did not even get to warm to touch I took it out of the clip soon as I soldered the common wire flow rate is awesome on new products not to bad on rework either.

In general I like working with this solder; but it does tend to collect, or 'glob up' on the end of my soldering iron. It's very 'sticky'. But it melts easier than the lead free stuff. I guess you should make sure you're in a well ventilated area when using this stuff, I don't think breathing in the lead solder fumes can be good for you. I'm using it mostly for arduino, raspberry pi, embedded programming type circuits. Haven't tried it w/ any SMD components yet. It will take me a long time to go through all of this solder, you get a good amount for your $. I'd buy it again and look forward to practicing more with it.

I am learning to build FPV Quads. Been using solder from other makers. Small spools. That solder is trash in comparison. I am new to soldering and this solder makes a big difference. I could actually make the xt60 connections to the ESC work and look pretty good. All the motor solders look professional now. The flow and pooling is great. 1lb of solder will last a very long time. Only thing was the shipping. It took a bit longer than expected.

After using this stuff at work for the last few years, I set up a workbench at home at got this for use there. Works great
