Printed Circuit Boards Assembly (PCBA) Process | PCBCart

Step 1: Solder Paste Stenciling. The first step of PCB assembly is applying a solder paste to the board. This process is like screen-printing a shirt, except instead of a mask, a thin, stainless-steel stencil is placed over the PCB. This allows assemblers to apply solder paste only to certain parts of the would-be PCB.
