COMPOSITE MATERIAL AND ELECTRON DEVICE

Title:

COMPOSITE MATERIAL AND ELECTRON DEVICE

Document Type and Number:

WIPO Patent Application WO/2011/137756

Kind Code:

A3

Abstract:

A composite material and an electron device are provided. The composite material comprises a heat conducting and electric conducting layer (41), a viscose glue layer (42) and an insulating layer (43), and the heat conducting and electric conducting layer (41) and the insulating layer (43) are pasted at the two sides of the viscose glue layer (42). The viscose glue layer (42) is electrically conductive. The electron device comprises electronic components (2) and shielding frames (3). Gaps are formed on insulating layer (43) at the positions relevant to the electronic components (2) and/or shielding frames (3) where the viscose glue layer is emerged, and the composite material is pasted on the electronic components and/or shielding frames by the viscose glue layer (42). The composite material can radiate and shield electromagnetism simultaneously and simplify the structure of the electron device.
