Problems solved by technology

However, the packaging substrate commonly used in the field of embedded circuit boards is made of bismaleimide triazine resin (Bismaleimide Triazine, BT), and the heat dissipation coefficient of BT is very low, which cannot provide good heat dissipation effect
As a result, the industry began to use ceramic substrates with high heat dissipation performance to make embedded circuit boards, but ceramic substrates are hard and brittle, not easy to slot and drill, and very difficult to process

Abstract

The invention discloses an embedded-type circuit board, which comprises a copper-clad ceramic substrate, a groove body and an electronic part, wherein the copper-clad ceramic substrate comprises a ceramic insulation layer and a first metal layer which is arranged on the first surface of the ceramic insulation layer; the groove body is arranged on the first metal layer; and the electronic part is fixed inside the groove body. The invention also provides a production method of the embedded-type circuit board. In the invention, the groove body is arranged on the metal layer of the copper-clad ceramic substrate rather than being arranged on the ceramic insulation layer, so that the electronic part can be embedded in the groove body, so the processing difficulty is reduced, and the high heat radiation performance of the copper-clad ceramic substrate can be utilized.

Description

technical field [0001] The invention relates to the technical field of circuit boards, in particular to a copper-clad ceramic substrate embedded circuit board and a manufacturing method thereof. Background technique [0002] With the increasing amount of information processing of various electronic devices, the demand for high-frequency and high-speed signal transmission is increasing. Embedding electronic devices into packaging substrates to make embedded circuit boards can effectively shorten the connection distance between electronic devices and packaging substrates, and provide a strong guarantee for high-frequency and high-speed signal transmission. Embedded circuit boards can also meet the development needs of high integration of packages and miniaturization of electronic products. [0003] Heat dissipation is a key issue to be solved by embedded circuit boards. However, the packaging substrate commonly used in the field of embedded circuit boards is made of bismalei...
