durable label material1) Increased Use of Highly Active Fluxes

Flux is a highly acidic substance that is used in the manufacture of PCBs to remove oxides from contact surfaces and chemically prepare them for soldering.  An ideal flux helps create strong solder joints while leaving a minimal amount of residue to be cleaned post soldering. Traditionally rosin based fluxes were used, but more and more companies have switched to highly active (ORH1), water based, no clean fluxes. These new fluxes are able to more easily dissolve oxides due to their stronger acidic characteristics plus they don’t require a cleaning process which helps reduce manufacturing costs.
