Manufacturing method of thermal conduction EMI shield paint for semiconductor with copper and nickel and graphene

摘要

The present invention relates to a method for manufacturing a thermally conductive electromagnetic wave shielding paint for semiconductor comprising copper, nickel and graphene, and more particularly, to a method for manufacturing a thermally conductive electromagnetic wave shielding paint for semiconductor, comprising: an oxide film removing step of removing an oxide film on a surface of a copper powder; A nickel coating step of coating the surface of the copper powder that has undergone the oxide film removing step with nickel to form an oxidation preventing film; And a graphene synthesis step of synthesizing graphene on the copper powder (1) through the nickel coating step,Coating the coating paint prepared according to the present invention on a heat radiating member of a semiconductor can effectively dissipate heat generated from the semiconductor device, reduce electromagnetic interference (EMI), shield the electromagnetic wave, And the like.;
