Ceramic-based printed circuit board and preparation process thereof
The invention relates to a ceramic-based printed circuit board which comprises a ceramic substrate, a copper-clad layer and a covering layer which are sequentially attached from bottom to top. The ceramic substrate comprises the following components in parts by weight: 65-85 parts of aluminum oxide, 20-30 parts of silicon oxide, 20-40 parts of silicon carbide and 1-5 parts of manganese oxide. The invention further discloses a preparation process. The process has the beneficial effects that the hardness can be effectively reduced, good heat transfer can be ensured, and the processing cost is reduced.
本发明涉及一种陶瓷基印制电路板，包括从下至上依次贴合的陶瓷基板、覆铜层、覆合层；所述的陶瓷基板包括如下重量比的各组分：氧化铝：65~85份，氧化硅20~30份，碳化硅20~40份，氧化锰1~5份。还公开了其制备工艺。本发明达到的有益效果是：既能有效降低硬度又能保证良好热传递、降低加工成本。
