Review on 🔩 Ultimate Lead Solder Wire: Kester24 6337 6403 331 – Premium Quality and High Efficiency by Justin Butler

Kester has always been my favorite solder. This particular grade is special - the flux dissolves in water. I recently completed two small synthesizer modules (music) using PCB through hole components. On the forum (Mutable Instruments) some advanced people talked about _blushing_ boards when assembled. Yes! In fact, it has to be flushed several times when new components are added. Important: there was no electricity, do not wash what is plugged into the outlet. Everything must be completely dry beforehand. Important: Do not wash switches or knobs (potentiometers). ) In general, stop rinsing before adding these parts. Cause: The solder contains flux that can "leak" between two closely spaced solder joints. There may be an almost invisible solder line in the leak. This can result in poor performance, intermittent issues, etc. Cleaning fixes this, but cleaning regular solder comes with some nasty things. Cleaning with this Kester soldering option requires warm water and a toothbrush. As far as I can tell run the board under warm water, clean and let dry completely. Add more components. repeated. Stop before adding switches, connectors, potentiometers, etc.
