Description

technical field [0001] The invention relates to the field of interface heat dissipation materials, in particular to a special heat-conducting adhesive for CPUs. Background technique [0002] With the increasing integration density of microelectronic devices, the heat dissipation requirements of microelectronic devices are also increasing. Therefore, it is of great significance to develop an interface heat dissipation material with high thermal conductivity. Due to its environmental friendliness and low cost, thermal conductive adhesives have gradually replaced traditional tin-lead solder interconnect materials. However, the development of traditional thermal adhesives also encountered some bottlenecks, such as low thermal conductivity, high density, and low stability. Contents of the invention [0003] The technical solution adopted by the present invention to solve the technical problem is to provide a special heat-conducting glue for CPU, which is characterized in that ...
