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

63/37 is a good low melting point eutectic leaded solder. The flux is strong and makes for very good flow. Its a bit messy because it has a large 3.3% flux core but that means it gets the job done. My favorite solder to use since its so easy. The flux doesnt need to be cleaned according to the datasheet. Kester 44 and Kester 48 are my favorite.

My favorite

Kester... What more can i say. one of the TOP brands in solder and flux. this solder has ALWAYS exceeded my expectations. I will never use another brand.

I used to use a thicker solder in the past but went with this. It melts quicker and flows better into solder joints. I read good reviews of this on electronics groups so based on those reviews purchased this and have not been sorry.

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

The shipping for this item was fast. The Kester 44 Rosin Core Solder is a great product for wire soldering. The 1lb. spool should last a long time before I have to buy another one. Worth the price.

Its the solder Ive been using for over 50 years.

Dont waste your time with that crap made in China. Buy US quality solder. This is the real deal. Very clean and strong results.

Good solder. Dont screw around; buy decent solder.

Really good stuff
