Shadow Mask

Shadow Mask

photo etched apertured shadow mask manufacturer in China

    Product Description

    The shadow mask is one of the technologies used to manufacture cathode ray tube (CRT) televisions and computer displays that produce color images. Another approach is the aperture grille, better known by its trade name, Trinitron.

    The shadow mask is the critical component of the colour picture tube and the important component for the choice of colour , its function concentrates on the limitation of electronics bound diameter and the screening direction , the electronics bound which is sent by the electronics gun goes scanning , during the scanning process , we should guarantee every bound gathering into the small holes situated on the screen , then these bounds will point to the regularized position through the small holes on the flat mask , and then three basic colours will be produced , at the same time , those useless electronics will be blocked by the mask board.

    Company Information

     If you are working on using vapor deposition to make OLEDs and other organic circuitry, please contact us, and our engineers are available to provide technical advice in this area.


    Smaller than metal masks made for solder paste printing, our custom shadow masks are typically made from stainless steel but are also available in nickel and other alloys. Athough we recommend stainless steel for most applications because it holds up well to temperatures and most chemicals, we have experience fabricating shadow masks from other metals as well. Our capabilities allow thicknesses of 0.03mm and up with the smallest opening beling 30 microns, the smallest space between openings beling 35 microns and critical feature tolerance of +/-10  microns.
