Kester 24-6337-0027 Solder Roll, Core Size 66, 63/37 Alloy, 0.031 Diameter

Great stuff night and day from hardware store stuff!!

This is the best solder on the market! I will never use that Radio Shack garbage again for anything but maybe wire or something.

1 lb is economical size to buy. 0.031 diameter is great size to use for many soldering applications.

What can i say, Im a novice when it comes to soldering and this solder makes me feel like a pro. easy melt, and harden in the blink of an eye, good for me with my shaky hands.

Excellent solder. Flows nicely, fillets well, doesnt spike out unless you use WAY too much heat and the rosin comes off easily with alcohol.

Delivered as expected.

Makes much better joints and much easier to use than R/S Chinese version. I highly recommend this over other solders.

worked fine for soldering to add mounting headers to Sparcfun XBee breakout boards. Wanted even smaller diameter but this worked OK.

Really god solder Used it for soldering key switches to my mechanical keyboard

I use this stuff mainly for audio cables and equipment. I dont think Ive made a bad solder joint yet using this. Runs a little wetter than some of the other stuff Ive used, but that results in virtually no oxidation.
