Abstract

본 발명은 콘덴서 내장 세라믹 다층기판에 관한 것으로, 좀 더 구체적으로는 콘덴서 내장 세라믹 다층기판의 상부 첫번째 층에는 공통단자인 Al 및 A6 이외에 A2, A3, A4 및 A5등의 보조단자를 형성하고(제3(a)도), 그 하부의 두번째 층에는 Bl, B2, B3, B4, B5, B6, B7, B8 및 B9등의 단자를 형성하며 (제3(b)도), 세번째 층에는 C1, C2, C3, C4, C5 및 C6등의 단자를 형성하여 (제3(c)도) 내부 콘덴서의 전극의 일부가 외부의 보조단자로 연결되므로서 내부 콘덴서의 정전용량을 가변시킬 수 있는 콘덴서 내장 세라믹 다층기판에 관한 것이다.The present invention relates to a ceramic multilayer substrate with a capacitor, and more specifically, an auxiliary terminal such as A2, A3, A4, and A5 is formed in the upper first layer of the ceramic multilayer substrate with a capacitor in addition to Al and A6, which are common terminals. 3 (a)), the second layer below it forms terminals such as Bl, B2, B3, B4, B5, B6, B7, B8 and B9 (Fig. 3 (b)), and the third layer contains C1, Built-in capacitor that can change the capacitance of internal capacitor by forming terminals such as C2, C3, C4, C5 and C6 (Fig. 3 (c)) and part of electrode of internal capacitor is connected to external auxiliary terminal The present invention relates to a ceramic multilayer substrate.

본 발명은 콘덴서 내장 세라믹 다층기판의 내부 콘덴서의 정전용랑을 보조의 콘덴서를 외부에 부착하거나 또는 내부 콘덴서의 전극층을 외부로 노출시켜 레이져 트리밍 후 유리질을 코팅하는 번거롭고 비효율적인 방법을 사용하지 않고 단지 소성 후 외부에서 단자의 연결을 조절해 주므로서 내부 콘덴서의 정전용량을 변화시킬 수 있어, 외부 보조 콘덴서를 부착하는 방법에 비하여 회로의 고집적화를 이룰수 있으며, 내부 콘덴서의 전극 부분이 외부로 드러나게 하는 방법에 비하여 공정을 단순화하여 생산 원가를 낮출 수 있다.According to the present invention, the internal capacitor of the internal capacitor of the ceramic multilayer substrate having the capacitor is attached to the outside of the auxiliary capacitor or the electrode layer of the internal capacitor is exposed to the outside, and the firing is not carried out using a cumbersome and inefficient method of coating glass after laser trimming. After adjusting the connection of the terminal from the outside, the capacitance of the internal capacitor can be changed, so that the circuit can be more integrated than the method of attaching the external auxiliary capacitor, and the electrode part of the internal capacitor is exposed to the outside. In comparison, production costs can be reduced by simplifying the process.
