Abstract

The invention discloses a DPC ceramic circuit board and a preparation method thereof. The method comprises the following steps: an electroplated thickened ceramic substrate is prepared, wherein the electroplated thickened ceramic substrate includes a ceramic substrate and a metal layer arranged on the ceramic substrate, and there is a copper line on the metal layer; and cutting is carried out: metal cutting is carried out on the surface of the electroplated thickened ceramic substrate, and in the process of cutting, a platform for placing the electroplated thickened ceramic substrate is a shock absorption platform, the ambient temperature and the temperature of the electroplated thickened ceramic substrate are controlled at room temperature, the precision range of temperature is + / -2DEG C,and rotary cutting is adopted. The circuit board preparation method of the invention avoids a certain degree of damage to the substrate caused by grinding and polishing, and the high requirement fora mirror surface can be hardly achieved by the cutting in the prior art. By using the circuit board preparation method of the invention, the DPC ceramic circuit board has a mirror surface, the reflectivity of the circuit board is improved, and the thickness of the circuit board after processing is very uniform.

Description

technical field [0001] The invention relates to the field of preparation of ceramic substrates, in particular to a DPC ceramic circuit board and a preparation method thereof. Background technique [0002] With the gradual deepening of electronic technology in various application fields, highly integrated circuit boards have become an inevitable trend. Highly integrated package modules require a good heat dissipation carrying system, while traditional circuit boards FR-4 and CEM-3 are in TC (thermal conductivity ) has become a bottleneck restricting the development of electronic technology. In the field of high-power LED lighting, materials with good heat dissipation properties such as metal and ceramics are often used to prepare circuit substrates, and the thermal conductivity of ceramic substrates can reach about 220W / M.K according to different preparation methods and material formulations. [0003] Ceramic circuit boards mainly include four categories: HTCC (High-Temperat...
