Kester 24-6337-0010 44 Rosin Core Solder 63/37 .020 1 lb. Spool

Good solder

The good stuff!

Kester 44 63/37 has pretty much been the co to solder for electronics work for a long time. this being .02 is easy handle for doing SMD work.

Simply good quality solder from a quality manufacturer. You wont go wrong with Kester products.

Will always use Kester solder on my repair or restore electronic products!!

top notch

I am used to Alphametals made in Brazil. The trade mark is BEST and it is really the best. This one from Kester is not good at all. The flux core is not continuous, so when you stat soldering, some spots go fine and some dont. I need to use extra SMD flux paste to finish the job, what takes longer and compromises the quality. I would say do not buy, but these company took over the market and that is the only option we have. The other option is to import from BEST in Brazil.

I had always used the cheapest solder I could find until I had some instruction from an electronics teacher with some good quality Kester solder. The difference is huge. I had some cheap solder with Chinese writing on it and tried it side by side with the Kester and the ease of use is very noticeable. This stuff melts more easily, flows where it should, and doesnt make those nasty blobs with tails. I had been thinking I was doing something wrong getting ugly solder joints. Turns out crap solder makes crap joints. Kester solder (with the right ratio) makes excellent solder joints.

This is what you need for SMD work, from the company whose name means solder.

I only use Kester solder. The 0.020 diameter is better for working on smaller PC board components.
