METHOD FOR MANUFACTURING ELASTIC GASKET FROM FOIL DIELECTRIC WITH DIAMOND MONOLAYERS FOR CONTACTING DEVICES IN MICROWAVE RANGE Russian patent published in 2023 - IPC H01R4/58 H05K3/42 

FIELD: electrical engineering.

SUBSTANCE: method for manufacturing an elastic gasket, which can be used when testing microwave monolithic integrated circuits (MICs) with an operating frequency of up to 50 GHz. Reducing errors is achieved by installing an elastic gasket between the microwave MIC housing and the measuring printed circuit board, while the method of manufacturing an elastic gasket from a foil dielectric with diamond monolayers includes the formation of metallized vias, the formation of a metallization pattern by the method of photolithographic etching, onto which a layer of conductive silver-based adhesive is applied using stencils and monolayers of nickel-metalized diamond powder with the same grain size selected from the range of 13-15 microns are formed, with a thickness of the adhesive layer equal to 80% of the grain size of the diamond powder, in this case, metallized grains of diamond powder are pressed 2-3 microns into the contact pads of the housing on one side and into the contact pads of the measuring printed circuit board on the other side. The thickness of the foil dielectric of 0.05 mm, as well as the diameter of the transition metallized holes of 0.1-0.15 mm, filled with conductive glue, reduce the parasitic components of inductance and capacitance, as well as ohmic resistance, expanding the possible operating frequency range when carrying out measurements to 50 GHz.

EFFECT: increasing test accuracy by reducing errors.
