Problems solved by technology

Nowadays, the performance of chips is getting higher and higher, followed by the rapid increase of chip heat generation, which makes chip heat dissipation a huge problem. In places with large spaces, chips often use radiators for heat dissipation, and mobile devices are often integrated. High, it is not easy to install a traditional radiator, and only relying on air heat transfer will cause the system to run unstable, and there is a need for a device that can transfer heat well and is easy to use

Abstract

The invention discloses a heat-conducting copper foil which comprises de-bonding layers, an adhesive, a copper foil and an insulation layer, wherein the insulation layer is attached to one side of the copper foil; the other side of the copper foil is coated with the adhesive; the adhesive is arranged on the other side of the insulation layer; the de-bonding layers are arranged on two sides of the adhesive. According to the mode, the heat-conducting copper foil has the advantages of high reliability, good heat conductivity, convenience in adhesion, good insulativity, small thickness, easiness in bending, low price and the like, and is suitable for heat dissipation of chips of small electronic products.

Description

technical field [0001] The invention relates to the field of metal films, in particular to a heat-conducting copper foil. Background technique [0002] Copper is a material that has been used for a long time. It has good electrical and thermal conductivity and is widely used in the electronics industry. Nowadays, the performance of chips is getting higher and higher, followed by the rapid increase of chip heat generation, which makes chip heat dissipation a huge problem. In places with large spaces, chips often use radiators for heat dissipation, and mobile devices are often integrated. High, it is difficult to install a traditional heat sink, and only relying on air heat transfer will cause the system to run unstable. There is a need for a device that can transfer heat well and is easy to use. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a heat-conducting copper foil, which can realize rapid conduction of h...
