Abstract
본 명세서는 열가소성 중합체, 도전성 금속 분말 및 유기 용매계를 포함하는 도전성 페이스트를 개시한다. 본 발명은 전술한 열가소성 중합체 및 금속 요소를 구비한 도전성 복합체를 더 포함하는데, 상기 금속 요소는 상기 복합체의 전체 부피에 대하여 약 30% 이상의 부피를 차지한다. 상기 복합체는 높은 온도에서 상기 페이스트로부터 형성된다. 상기 페이스트는 상기 페이스트가 상기 복합체로 변환되는 처리 조건하에서 전기·전자구성 요소를 접속하는 단계를 포함하는 공정에서 채용된다,The present disclosure discloses a conductive paste comprising a thermoplastic polymer, a conductive metal powder and an organic solvent system. The present invention further comprises a conductive composite comprising the thermoplastic polymer and the metal element described above, wherein the metal element occupies a volume of at least about 30% of the total volume of the composite. The composite is formed from the paste at elevated temperatures. The paste is employed in a process comprising connecting electrical and electronic components under processing conditions in which the paste is converted into the composite.
