    […] Flux plays a vital role in any soldering process and electronics PCB manufacturing and assembly. Flux removes any oxide and prevents oxidation of metals and hence helps in better soldering quality. In Electronics PCB Assembly process, flux removes any oxide and impurities from the copper tracks on the PCB and oxides from the leads of the electronic components. These oxides are biggest resistance in good soldering joint and by removing these oxides, fluxes play a very vital role here. […]
