NANO STENCIL

An SMT (Surface Mount Technology) stencil is used in the electronics manufacturing process, specifically for applying solder paste to printed circuit boards (PCBs) before components are soldering. By coating a special ultra-hydrophobic material on the surface of an SMT stencil, the stencil's performance is significantly increased. This allows the solder paste to be printed and cleaned more easily.

Three methods used to fabricate SMT stencils.

Laser-Cut Stencils: These stencils are made by cutting holes in a thin metal sheet using a laser. They are highly precise and suitable for fine-pitch components.
Electroformed Stencils: Made by electroforming, these stencils are typically used for very fine-pitch or small-pitch components.
Chemically Etched Stencils: These are less common but can be used for certain types of PCB designs.
