Review on Premium Kester 331 Organic Core Solder 63/37 .031 1 lb. Spool for Efficient Electronics Soldering by NTE Electronics (1) by Vincent Pavelko

Revainrating 5 out of 5

General Purpose Electronic Repair Solder

This is a very easy to use lead based solder that is great for electronics repair (especially new lead free boards) and PCB assembly. Water based flux is very corrosive and destroys oxidation on things like old synths and industrial products. Warning: You MUST rinse the board with water when finished as residue is still corrosive. However, unlike pitch ore flux, it is simply rinsed off.

Pros
  • Flux: 331 @ 3.3% | core: 66 | Type: Water Soluble
Cons
  • Piggy Bank Price
