Stencils, also known as SMT Stencil, are special molds for SMT. Its primary function is to help the deposition of solder paste; the purpose is to transfer a precise amount of solder paste to an accurate location on the bare PCB.
SMT stencils are the medium you use to transfer that solder paste onto the PCB. Both SMT stencil and laser stencil can be recycled. Recycling can significantly reduce the production costs of enterprises.
