The metal shadow mask is a structure in which various functional patterns are made on film, plastic or glass substrate materials and accurately positioned for selective exposure of photoresist coatings. Metal shadow mask are widely used, and shadow mask are required in areas involving photolithography, such as IC (Integrated Circuit, integrated circuit), FPD (Flat Panel Display), PCB (Printed Circuit Boards, printed circuit) Board), MEMS (Micro Electro Mechanical Systems), etc.
The shadow mask is also often used for optical research in universities and research institutes; the most precise air slits and shoulder strips of the domestic comparison shadow mask are basically 10um; if it is a single slit, it can be 5um, The tolerance is 2um.
