Abstract

본 발명은 아연을 전기분해하여 제조된 1∼20㎚ 크기의 나노입자 및 그 제조방법에 관하여 개시한다. 상기 나노입자는 111∼130℃의 온도 범위에서 표면 용융된다. 상기 나노 입자를 함유한 솔더 볼은 180℃ 이하에서 소결 할 수 있는바, 첫째 Rflow 공정시 가열 온도를 240℃에서 180℃까지 낮출 수 있기 때문에 기존에 사용되고 있는 74㎾의 에너지를 소모하는 Reflow 공정 장치를 56㎾의 에너지 사용으로 해결할 수 있어 24%의 에너지를 절약할 수 있다. 둘째 Reflow 공정의 온도를 낮춰 PCB 보드의 변형을 최소화할 수 있고, 유리전이 온도가 낮은 PET와 같은 저가 고분자 재료를 사용할 수 있게 됨으로써 단가가 저렴한 실장 재료의 적용 분야가 창출될 수 있다. 그리고 셋째 10㎚ 이하 크기의 나노입자를 사용할 경우 패드 위의 솔더 페이스트 균일성을 높일 수 있고 나노 솔더 잉크의 경우 입자의 크기가 작음으로 인해 미세 Patterning의 한계를 극복할 수 있다(도 4).
