- 전기전도성을 갖는 저융점 합금필러와 상기 저융점 합금필러의 융점 보다 높은 융점을 갖는 고분자매트릭스를 포함하는 등방성 전도성 접착제에 제1단자의 적어도 일부를 디핑하는 단계와,상기 등방성 전도성 접착제가 디핑된 상기 제1단자를 이에 대응되는 제2단자에 배치하는 단계,상기 저융점 합금필러의 융점 보다 높고 상기 고분자매트릭스의 경화온도 보다 낮은 온도까지 가열하여 상기 저융점 합금필러를 용융시키는 단계와,상기 고분자매트릭스의 경화온도 보다 높거나 같은 온도로 가열하여 상기 고분자매트릭스를 경화시키는 단계를 포함하여 구성되는 도전성 접착제를 이용한 단자간 접속방법.
- 제 1 항에 있어서, 상기 저융점 합금필러를 용융시키는 단계와 상기 고분자매트릭스를 경화시키는 단계 사이에는, 상기 가열한 온도를 일정 시간 유지하여 저융점 합금필러의 융합 및 젖음특성을 발현시키는 단계가 더 포함됨을 특징으로 하는 도전성 접착제를 이용한 단자간 접속방법.
- 제 2 항에 있어서, 상기 저융점 합금필러의 융합 및 젖음특성을 발현시키는 단계에서 가열은 상기 저융점 합금필러의 융점보다 15 내지 25℃ 높은 온도로, 15 내지 25 초 동안 지속됨을 특징으로 하는 도전성 접착제를 이용한 단자간 접속방법.
- 제 3 항에 있어서, 상기 등방성 전도성 접착제에는 35% 내지 45% 부피를 차지하는 저융점 합금필러가 함유됨을 특징으로 하는 도전성 접착제를 이용한 단자간 접속방법.
- 제 4 항에 있어서, 상기 저융점 합금필러는 Sn-58Bi, Sn-48In, Sn-57Bi-1Ag, Sn-9Zn, Sn-8Zn-3Bi, Sn-3.5Ag 중 어느 하나임을 특징으로 하는 도전성 접착제를 이용한 단자간 접속방법.
- 제 1 항 내지 제 5 항 중 어느 한 항에 있어서, 상기 등방성 전도성 접착제에 제1단자의 적어도 일부를 디핑하는 단계는 상기 등방성 전도성 접착제가 스퀴즈되어 접착제층이 형성된 더미기판에 상기 제1단자의 일부가 디핑되어 이루어짐을 특징으로 하는 도전성 접착제를 이용한 단자간 접속방법.
- 제 6 항에 있어서, 상기 제1단자는 범프타입 또는 리드타입으로 형성됨을 특징으로 하는 도전성 접착제를 이용한 단자간 접속방법.
