Thermal Pad Used for GPU, CPU, DDR, RAM and CHIP

Shenzhen Aochuan Technology Co.,Ltd. was established in 2004, is a leading Chinese developer and manufacturer of products for Thermal Interface Materials(TIMs), for cooling your electronic devices.

AOK technical service staff can help engineers determine the appropriate materials for their application and heat transfer requirements.

AOK brand thermal pads are ideal for height differences and unevenness in heat sinks and to bring the elements to be cooled. Given their high elastic and low hardness is achieved already by a low pressure is a very good fit to the surface. There are balanced all the large and small differences in elevation, even of microscopic grooves to visible imperfections.
