METHOD FOR PROTECTING ELECTRONIC CIRCUIT BOARDS FROM MOISTURE Russian patent published in 2005 - IPC

Abstract RU 2265976 C2

FIELD: mechanical engineering, can be implemented in technology for manufacturing and protecting electronic circuit boards from moisture.

SUBSTANCE: to increase moisture resistance of circuit boards, porosity in volume of dielectric of board is filled, for filling, thermal-hardening polymerization-capable compositions are used based on glycol ethers of acryl acids and additional polymer covering layer is formed. Thermal processing is performed after applying polymer covering.

EFFECT: higher efficiency.
