Commercialization of Thermal Conductive Sheet Silicone Type ZX11N, Suitable for Heat Dissipation for IC Chips Such as Those Required in Communication Base Stations and Automobiles
- Satisfying Both High Thermal Conductivity and Flexibility -
Dexerials Corporation (Headquarters: Shimotsuke-shi, Tochigi; Representative Director and President: Yoshihisa Shinya; hereinafter, Dexerials) announced that it has commercialized the thermal conductive sheet silicone type ZX11N, which satisfies both high thermal conductivity and flexibility. Since the product has superior long-term reliability, which means long-term use does not deteriorate or degrade the performance of the product, it is suitable for heat dissipation for IC chips that are in charge of information processing at 5G communication base stations and data centers as well as for self-driving of automobiles.
Recently, transaction volumes processed at communication base stations and data centers have increased rapidly with the practical application of 5G communications. In addition, electronics devices and automobiles are becoming increasingly sophisticated and high performance, which is requiring that greater volumes of information be processed by IC chips. In response to this large volume of information being processed, information processing capacity has been improved by heightening the operating frequency of IC chips and the number of core processors. However, since IC chips, which are a semiconductor, have their own resistance, their operation generates heat, and coping with this problem is already a big challenge.
The thermal conductive sheet efficiently releases heat by filling the gap between an IC chip, which generates the heat, and a heat sink, etc., which dissipates it. Therefore, the thermal conductive sheet is required to have high thermal conductivity and flexibility for cohesion and level difference absorption. However, since use of a lot of materials (fillers) having high thermal conductivity will harden the whole sheet, thermal conductivity and flexibility are generally in a trade-off relationship.
Our thermal conductive sheet silicone type ZX11N solves this problem and achieves both high thermal conductivity of 11 W/m・K and flexibility. The product has high thermal conductivity as a thermal conductive sheet by arranging boron nitride fillers that have different thermal conductivity aligned in respective directions, using the unique alignment technology Dexerials developed with its thermal conductive sheet carbon fiber type . It can also reduce the amount of filler used, which offers greater flexibility.
Further, the boron nitride fillers feature long-term stability and electrical insulation. They thus offer high reliability and electrical insulation throughout the thermal conductive sheet. Dexerials will actively propose the product for heat dissipation for IC chips used at communication base stations and data centers, which are social infrastructure requiring stable operation, as well as for IC chips used for information processing for self-driving of automobiles, which demand long-term reliability for safety.
Details of Thermal Conductive Sheet Silicone Type ZX11N
- Thermal conductive sheet Silicone type ZX11N
- Satisfies both high thermal conductivity and flexibility using unique alignment technology
Achieves high thermal conductivity by arranging boron nitride fillers that have different thermal conductivity aligned in respective directions by using the unique alignment technology Dexerials has developed in the thermal conductive sheet carbon fiber type . Able to reduce the amount of filler used, which satisfies both the thermal conductivity of 11W/m・K and flexibility (hardness) of 55 (Shore OO, ASTM D2240).
- Holding High Reliability by Employing Boron Nitride Fillers
By using the boron nitride that has long-term stability as the filler, the entire thermal conductive sheet achieves high reliability with less deterioration and performance degradation even after extended use.
