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

Have nothing to say cause I have used it before at my work place.

Highly recommended -- not the cheapest but worth the price. I wish it came in half the size / half the price option because i did not need that much.

Works great for what it is

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 pcbs 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 LEDS 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. GREAT JOB.....

In general I like working with this solder; but it does tend to collect, or glob up on the end of my soldering iron. Its very sticky. But it melts easier than the lead free stuff. I guess you should make sure youre in a well ventilated area when using this stuff, I dont think breathing in the lead solder fumes can be good for you. Im using it mostly for arduino, raspberry pi, embedded programming type circuits. Havent 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 $. Id buy it again and look forward to practicing more with it.

great!

Melts nice and easily. Flows smoothly. I learned to solder 10 years ago, and this is some of the best solder Ive ever used - definitely worth the premium.

This solder is very flexible and easy to use. It melts and cools quickly and makes soldering very easy!

This solder is great. The rosen core really helps. It flows smoothly and clean. Highly recommended.

This is really excellent solder. It arrived fast
