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

Good solder and plently of it!

This is a really easy solder to use, its now my preffered one for repairs etc...

This solder here is the ONLY solder I use. Never had an issue with any types of connections!

Lead and tin mixture that when heated flows over copper conductors like butter

I found it to be difficult to use. It does not solder as easy as regular flux solder does. The flux still needs to be cleaned off the P.C.B after use. I would not buy this again unless the kit maker requires it to complete their P.C.B. This was the reason I bought the No-Clean flux solder in the first place.

I typically use another formula of Kester solder. Decided to give this a try. It works very much like more common Kester solder. I noticed much less residue. It seems to have a slightly higher melting point and a bit less flow (I do through-hole components). The difference is small and the decreased residue is a real plus.

Use it when soldering flight control boards on RC aircraft.

Not much to say, flows better for me than really cheap stuff but that could just be my technique lol

I made some research before ordering and found that Kester seems to be the brand to go for. I was tempted by cheaper products from others but in the end I did go for Kester 245 no-clean core solder 63/37. I am soldering not too much and wouldnt call me a professional but even as a hobbyist I noticed a difference between cheaper 60/40 I had before and this one. I am not sure if that is because of the 63/37 grade or because my previous stuff was from some unknown manufacturer but in the end I dont care. I feel it was the right decision to go with the Kester product. It works for me well.

This is the s***, easy flowing, easy to work with, a must have for wiring jobs ,highly recommend, you will not be disappointed. ...
