KESTER SOLDER 24-6337-0027 Solder Wire, 63/37 SN/PB, 183°C, 1LB

63% lead and 37% tin is generally used considered perfect for electronics hand soldering. Kester 44 rosin core flux is generally considered one of — if not the — best for electronics hand soldering. And 0.031” is just about the best diameter for small chassis, through-hole electronics, and SMT down to about 0805 and even 0402. As a result, this is a great solder for most electronics hand soldering. This is a great solder.

Ease of working with and nice finish work

This is good quality solder. Great for hobbyists.

Please check the DOM [Date of Manufacture] on the top label of all Kester Solder. Kester states that their solder has roughly a 2 year shelf life. So when you buy solder look at the DOM and with a pen write an expiration date of exactly two years on the label in case you notice problems with your soldered joints after that date. I have Kester solder that is expired by two months and I havent noticed anything yet but if I didnt I would buy a new 1lb. spool. There are distributors out there that are very good at making sure they provide their customers with the newest solder product that takes into account this very thing. In my opinion all solder should be sold based on this expiration date. If the solder in the photos are representations of what I might be buying. The DOM on these go back more than 6 years. Jun/2014 and Jun/2016 over about 4 years expired solder. I dunno... you decide. Not all things expired are garbage. I just wanted to inform you. Alex

Excellent solder. Using it for board repair on macbooks.

1 of best solder I’ve used.

I’ll be buying again

Verry good deal

In the 20 or so odd years Ive been building, making, remaking and hacking, I have used alot of junk solder. My life wouldve turned out much differently had I found Kester 63/37 back in the 90s. The remainder of my days will be fill with regret and perfect solder joints

Good solder for fine work.
