[0002] SMT stencil, also known as SMT Stencil, is professionally called "template". The most widely used material is stainless steel, commonly known as stencil. It is the template for printing solder paste onto the PCB circuit board in the first step of SMT surface mounting. In the existing SMT stencil production process, the stencil is placed inside the printing machine. After a long period of printing operation, residual solder paste will cause the stencil hole wall to be blocked. During this period, the stencil needs to be removed and taken to the cleaning machine for cleaning. After cleaning, the stencil needs to be placed on a marble platform to test the tension. After completion, the stencil is moved to the visual inspection platform cabinet to check the cleanliness.
