HALOGEN-HYDROCARBON POLYMER COATING Russian patent published in 2014 - IPC H05K1/18 H05K3/28 H05K3/34 C09D4/00 C09D185/00 C09K15/32 

FIELD: chemistry.

SUBSTANCE: invention relates to polymer coatings, namely, to a halogen-hydrocarbon polymer coating for electric devices. A printed circuit board (PCB) includes a substrate, including an insulation material. The PCB additionally includes multitudes of electroconductive printing paths, connected to at least one substrate surface. The PCB additionally includes a multi-layered coating, precipitated on at least one substrate surface. The multilayered coating covers at least a part of a multitude of the electroconductive paths and includes at least one layer of the halogen-hydrocarbon polymer. The PCB additionally includes at least one electric component, connected by a solder connection to at least one electroconductive printing path, with the solder connection being soldered through the multilayered coating in such a way that the connection adjoins the multilayered coating.

EFFECT: prevention of oxidation or corrosion of metal surfaces, capable of preventing the formation of strong solder connections or capable of reducing a service term of the said connections.
