A: PCB Solder paste is a material used in electronics manufacturing to facilitate soldering. It’s a mixture of tiny solder particles suspended in a flux medium. When applied to the pads of electronic components and printed circuit boards, solder paste holds the components in place and helps create robust and reliable solder joints when heated. The flux in solder paste removes oxides from the metal surfaces, allowing the molten solder to flow and bond the components together as it cools.
