Joy Technology Co.,Limited

SMT Printing stencil opening shape and size requirements: For simple PCB assembly, 

glue technology is preferred. Dispensing is preferred. CHIP, MELF, SOT components are printed through the stencil. The IC uses glue to avoid stenciling. Here, only the CHIP, MELF, SOT printing stencils are recommended for the opening size and opening shape. 

1. Two diagonal positioning holes must be opened at the diagonal of the stencil, and the FIDUCIAL MARK point opening should be selected.
2. The openings are long strips. Inspection method 

1) Check the opening and center the stretched net by visual inspection. 

2) Check the correctness of the stencil opening through the PCB entity.

3) Verify the length and width of the opening of the stencil and the smoothness of the wall of the hole and the surface of the steel sheet with a graduated high power microscope. 

4) The thickness of the steel sheet is verified by detecting the thickness of the solder paste after printing, that is, the result is verified. Conclusion The stencil design technology requires a period of trial and control, and the printing quality is well controlled. The PPM of the SMT welding quality defect is reduced from about 1300ppm to about 130ppm. Due to the development of the packaging direction of modern electronic components, higher requirements are also placed on the design of steel mesh.
