DEVICE FOR SPRAYING AN ANTIREFLECTION COATING OF A PHOTOCONVERTER Russian patent published in 2018 - IPC C23C14/04 B82B3/00 

FIELD: electrical equipment.

SUBSTANCE: invention relates to a device for spraying an antireflection coating of a photoconverter and can be used in electronic engineering. Shield in the device is located on the front side of the substrate. In the body, landing nests are made with the possibility of fixing the position of the substrate. Shield and body are made in the form of a solid metal frame with holes for mounting sockets, which have the configuration of a photoconverter. Dimensions of the holes exceed the dimensions of the photoconverter by a value from 0.1 to 0.2 mm. Contact areas of the photoconverter are located on the flat projections of the mask, having a thickness of 0.1 to 0.5 mm and located along the perimeter of the holes for the mounting sockets. Sprayed surfaces of the shield and body are located in the same plane. On the rear side of the photoconverter metallized silicon substrates are arranged in the mounting sockets, by means of which contact areas are pressed against the shield by means of plate springs fixed on the frame. Surface of the flat projections is covered with a layer of thermally and chemically resistant polymeric material with a layer of metallization deposited on it and on the surface of a solid metal frame.

EFFECT: technical result consists in increasing the yield of suitable photoconverters.
