## Description

MG Chemicals RA Flux Sn60/Pb40 Leaded Solder is an electronic grade solder wire. It uses a classical tin-to-lead alloy ratio, which is complemented with a RA-like flux core. These solder wires meets J-STD-004 and J-STD-006 specifications. It melts at a slightly higher temperature range than the 63/37 solder. It results in robust and reliable joints that are highly resistant to whisker formation. The RA Flux residues are non-corrosive and non-conductive therefore can be left on the board or cleaned with one of MG’s flux removers.

### ⭐⭐⭐⭐⭐ Review
*by C***H on 20 August 2025*

An old timer who taught me how to properly solder turned me on to this stuff. He told me to not waste my money on anything else and then he thumped me lightly on the head for good measure. He was right, as always. This is the good stuff. (It wasn't really a thump. It was more like a bump, to let me know he cared) (No, I'm not promoting violence. Calm down)
