AI Technical Summary

Technical Problem

Existing embedded circuit boards cannot meet the increased heat dissipation requirements after a large number of electronic components are embedded, resulting in reduced reliability of electronic components.

Method used

Electronic components are embedded in an insulating substrate, and thermal conductivity is achieved between the first phase change material and the first outer circuit layer. The second phase change material and the grooves of the second outer circuit layer are arranged to form a heat dissipation zone, thereby improving the longitudinal thermal conductivity.

Benefits of technology

It improves the longitudinal thermal conductivity and heat dissipation area of ​​electronic components, ensuring the normal operating temperature of electronic components within the insulating substrate and enhancing reliability.
