PCB SMT Laser Stencil is also called SMT PCB steel plate, its main function is to help the deposition of solder paste, and transfer the accurate amount of solder paste to the precise position on the bare PCB. The Laser PCB stencil is composed of a mesh frame, a wire mesh and a steel sheet. There are many holes in the steel sheet, and the positions of these holes correspond to the positions on the PCB that need to be soldered. When in use, the PCB is placed under the PCB stencil, and the solder paste is leaked to the PCB through the small holes in the fixed position on the PCBA smt laser stencil.
