Abstract

이 발명은 전기접촉을 시키는데 쓰이는 고가의 은 페이스트를 대체하기 위한 재료로 저렴한 은 페인트와 에폭시를 혼합한 전기전도성 에폭시를 개발한 것이다. 이 방법에서는 인 페인트로 Western Gold&Platinum사의 Type 1570 스크린 은 페인트와 Emerson&Cuming사의 Stycast 1266 에폭시를 섞어 실온에서 경화시킴으로 미세한 은 분말이 균일하게 분포되어 있는 은-에폭시 복합체를 만든다. 복합체내 은 분말의 농도(부피비)를 0.2 이상으로 택하면 20Ω-1㎝-1이상의 겉보기 전기전도도를 기대할 수 있으며, 특히 기존의 은 페이스트에서와는 달리 열처리가 반드시 필요하지는 않은 장점이 있다. 또한, 역학적인 강도를 보강시키기 위해 열처리를 하는 경우에도 100℃ 정도의 저온 열처리로 충분하다.The present invention was developed as an alternative to the expensive silver paste used to make electrical contact, and has developed an electrically conductive epoxy mixed with inexpensive silver paint and epoxy. In this method, a phosphorus paint is mixed with Western Gold & Platinum Type 1570 screen silver paint and Emerson &Cuming's Stycast 1266 epoxy to cure at room temperature to form a silver-epoxy composite with a uniform distribution of fine silver powder. If the concentration (volume ratio) of the silver powder in the composite is chosen to be 0.2 or more, the apparent electrical conductivity of 20Ω -1 cm -1 or more can be expected. In particular, unlike the conventional silver paste, heat treatment is not necessarily required. In addition, low temperature heat treatment of about 100 ° C. is sufficient even when heat treatment is performed to reinforce mechanical strength.
