USA Quality

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.

Very good solder. More involved process to remove solder from iron with brass shaving method. Much better than China brands without a doubt. You get what you pay for with this product. I highly recommend this product.

Its solder, its Kester. Not much more you need to know.

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.

... and kind of amazed too. I mean, its 37% lead. About five ounces of lead per roll. That snaps off into little hanks that are just the right size for two and four legged friends to pick up and chew on. ROHS solder is a more sensible, safer option no doubt, but it just feels wrong to use Euro-weenie stuff on electronics made in an era when techs stuck the solder in their mouth for a third hand and made cheater plugs with alligator plugs, washed down with unfiltered Chesterfield breaks.

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.

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.
