Solder paste is a special material used to connect electronic parts together on circuit boards. Think of it like a metallic glue that becomes solid when heated. Technicians and repair specialists use it to attach small components like chips and resistors to circuit boards. It comes as a grey or silver-colored cream that's applied carefully using special tools, similar to how a baker might pipe frosting. When heated properly, it creates strong electrical and physical connections between components. This skill is fundamental in electronics assembly, repair work, and manufacturing roles.
