By definition, it infers to the stainless steel sheet comprising of laser-cut openings deployed in placing solder paste on printed circuit boards. It is instrumental for SMT or surface-mount technology, especially on component placement. The stencil’s primary use entails the deposition of solder paste to designated spots on a bare circuit board. Solder paste deposits then allow components to get placed and aligned on the printed circuit board.
