Low Solids Content Fluxes Available to Purchase

The arrival of low solids content flux on the electronics production market represents something of a revolution. Traditionally, the electronics industry has used, and is still using, successfully rosin fluxes containing between 15% and 35% solids content, for wave soldering electronics assemblies (PTH and single‐sided PCBs). It is therefore surprising to find that today fluxes containing between 2% and 10% rosin can be both efficient and cost‐effective.
