To execute small electrical soldering, the necessity of a jar of rosin flux is inevitable. Flux is a chemical cleaning agent required for the soldering process of electronic components. Before and during the soldering process, you need to apply flux to deoxidize the molten metal.
surface can cause poor solder connections. As a cleaning agent, flux is also used to absorb any impurities from the molten metal. Otherwise, any dirt or contaminant may lead to electrical malfunctions.
