Description

고체전해 콘덴서의 제조방법Manufacturing method of solid electrolytic capacitor

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제6도 내지 제9도는 본 발명 방법의 설명도로서, 제6도는 제1의 화성 처리상태를 표시하는 측단면도.6 to 9 are explanatory views of the method of the present invention, and Fig. 6 is a side cross-sectional view showing a first chemical conversion treatment state.

제7도는 콘덴서 엘리먼트의 중요부분 확대도.7 is an enlarged view of an important part of a capacitor element.

제8도는 제2의 화성 처리상태를 표시하는 측단면도.8 is a side cross-sectional view showing a second harmonic processing state.

제9도는 제2의 화성처리 종료후에 있어서의 콘덴서 엘리먼트의 중요부분 확대도.9 is an enlarged view of an important part of the condenser element after the completion of the second conversion process.

Claims (1)

벨브작용을 보유하는 금속분말을 소망하는 형상으로 가압성형하여 소결하여서 이루어진 콘덴서 엘리먼트(1)를 pH가 8이상의 염기성 용액을 사용하여 화성처리하는 것에 의하여 콘덴서 엘리먼트의 표층부(1b)에 심층부(1a)보다 두꺼운 막의 산화층(4)을 형성하는 공정과, 이 공정후 콘덴서 엘리먼트를 산성용액을 사용하여서 화성처리하는 것에 의하여 콘덴서 엘리먼트의 심층부에 염기성 용액에 의한 심층부의 산화층(4a)의 막두께보다도 두껍고, 또한 표층부보다 얇은 막두께의 산화층(6)을 형성하는 공정을 포함하는 것을 특징으로 하는 고체전해 콘덴서의 제조방법.The deep layer portion 1a is formed on the surface layer portion 1b of the condenser element by subjecting the condenser element 1 formed by pressing and sintering a metal powder having a valve action to a desired shape with a basic solution having a pH of 8 or more. Thicker than the film thickness of the oxide layer 4a in the deeper portion of the deeper portion of the condenser element by the basic solution by forming a thicker oxide layer 4 of the thicker film and subjecting the condenser element to an acidic solution after this step. And a step of forming an oxide layer (6) having a film thickness thinner than that of the surface layer portion. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
