SMT stencil
SMT stencil
Kingsheng Surface-mount technology (SMT) is a method of producing PCBs where the components are mounted or placed directly onto the surface of the board.
What is the stencil is designed to allow a smooth transfer of material (solder paste) onto the bare PCB. It is crucial in ensuring that the PCBA material is placed with precision. It is also vital in ensuring that deposits are formed with the proper shape and PCBA size. The SMT stencil is critical to ensure that the PCB assembly process can be operated with a high-yield output.
The PCB stencil provides a tool for accurate PCB solder paste deposition, allowing the process to be repeated multiple times. The PCB solder paste is printed through the holes in the SMT stencil, forming deposits that hold the PCB components in place. The stencil provides the accuracy needed to ensure the solder is printed in precisely the right place on the PCB.
The way in which the stencil is PCB designed can be varied based on thickness, the size of the aperture, and the shape of the aperture.

Hand/ rework PCB stencils are used to print individual components onto a PCB. In general, they are used in rework situations, but can also be used in developing prototypes. The stencil includes a flag that allows the PCB stencil to be hand-held
