Abstract

The invention discloses a high-heat-conductivity double-sided adhesive tape. A first heat conducting adhesive layer, a graphite layer and a second heat conducting adhesive layer are arranged between a light strip type PET film and a heavy strip type PET film; the graphite layer is obtained by the following technological method; the technological method comprises the following steps: coating each of the upper and lower surfaces of a polyimide thin film obtained in the first step with a layer of graphite modifier to obtain a treated polyimide thin film; heating the treated polyimide thin film to 800 DEG C, preserving the heat of the polyimide thin film, and then heating to 1,200 DEG C to obtain a pre-burnt carbonized film; rolling the pre-burnt carbonized film obtained in the fourth step by a rolling machine; heating to 2,400 DEG C, preserving the heat, and then heating to 2,900 DEG C to obtain a primarily burnt graphite film; rolling the primarily burnt graphite film obtained in the fifth step to obtain the graphite layer. According to the high-heat-conductivity double-sided adhesive tape, local overheating is avoided; furthermore, the uniformity of the heat conductivity of the adhesive tape is realized, and the heat dissipation performance stability of the product is improved.

Description

High heat-conducting double-sided adhesive tape
Technical field
The present invention relates to a kind of high heat-conducting double-sided adhesive tape, belong to double faced adhesive chip technology field.
Background technology
Nowadays,, along with the development of computer technology, the trend of development of computer is to develop lighter and thinner product. ExampleAs, panel computer and notebook computer become more and more popular, because the profile of their dexterities. Because the size of these products becomes moreLittle, heat radiation is a considerable aspect all the time,, high temperature can reduce performance, reliability and the service life of electronic equipment. CauseThis, current electron trade proposes more and more higher requirement for the heat sink material as heat control system core component, in the urgent need toA kind of high-efficiency heat conduction, light material pass heat rapidly, ensure that electronic equipment normally moves. All backing is that one existsBetween thermal source and secondary unit, transmit hot heat exchanger, its surf zone and shape are more conducive to heat radiation compared with thermal source.By equal backing, the heat " diffusion " being produced by thermal source is to secondary unit, and the heat of so well being eliminated in thermal source is amassedHold.
