Abstract
To enhance the thermo-mechanical properties of polyimide films which have potential application for the FCCL, we have synthesized the poly(amic acid)s composed of 4-components PMDA/BTDA and PDA/ODA as monomer system, and then they were effectively converted into 4-component polyimide films by thermal imidization process. It has been found that CTE values in the range of 100∼200 ℃ dcreased with the amount of PDA, which also caused 36% and 59% increases in tensile modulus and strength respectively. And also, peel test results on 3-layered copper clad laminate using 4-component polyimide films showed excellent adhesion strength above 1.8 kgf/cm. On the basis of obtained results it can be concluded that 4-component polyimide films may be applied for the high performance FCCL base films.

Flexible copper clad laminate(FCCL) 적용을 위한 폴리이미드 필름의 열적-기계적 성질 향상을 위해, 4성분계 PMDA/BTDA 그리고 PDA/ODA 단량체로부터 폴리아믹산을 합성하였고, 이를 효과적으로 열적 이미드화 공정을 통하여 4성분계 폴리이미드 필름을 제조하였다. 4성분계 폴리이미드 필름의 CTE 값은 100∼200 ℃ 범위에서 PDA의 함량에 따라 감소하였고, 인장 계수와 인장 강도는 36% 그리고 59% 각각 증가하였다. 그리고 4성분계 폴리이미드 필름을 사용한 3층 유연성 기판의 peel test 결과는 1.8 kgf/cm 이상의 좋은 접착 강도를 보였다. 이와 같은 결과들로부터 4성분계 폴리이미드 필름은 고성능 FCCL을 위한 기본 필름으로 적용할 수 있다.
