Abstract:
A printed circuit board with built-in vertical heat dissipation ceramic block, and an electrical assembly are disclosed. The electrical assembly includes the board and a plurality of electronic components. The printed circuit boards includes a dielectric material layer defining at least one through hole, at least one ceramic block corresponding to the through hole, at least one fixing portion for joining the ceramic block to the through hole of the dielectric material layer, a metal circuit layer provided on upper surfaces of the dielectric material layer and the ceramic block, and a high thermal conductivity layer provided on lower surfaces of the dielectric material layer and the ceramic block. The printed circuit board allows the location and size of the ceramic block to be modified according to requirements, so as to implement complicated circuit designs, achieve good effect of thermal conduction, control thermal conduction path, and reduce manufacturing cost.

Claim (Index 1):
A printed circuit board, comprising:\n a dielectric material layer, which has a first upper surface and a first lower surface opposite to the first upper surface, and defines at least a through hole extending through the first upper and lower surfaces; at least one ceramic block located in the through hole of the dielectric material layer, the ceramic block having a second upper surface and a second lower surface, the ceramic block having thermal conductivity greater than the dielectrical material layer; at least one fixing portion disposed around the ceramic block located in the through hole for joining the ceramic block and the dielectric material layer, such that the second upper surface of the ceramic block is flush with the first upper surface of the dielectric material layer, and the second lower surface of the ceramic block is flush with the first lower surface of the dielectric material layer; a metal circuit layer provided on the first upper surface and the second upper surface; and a high thermal conductivity layer having thermal conductivity greater than the ceramic block and provided on the first lower surface and the second lower surface.
