Abstract

본 발명은 볼 그리드 어레이의 인쇄회로기판상에 솔더 볼을 배치하는 장치 및 방법에 관한 것으로, 솔더 볼의 배치에 있어 배치장치의 각 구성 요소들의 정렬배치가 용이하게 정렬수단을 제공하고, 그 인쇄회로기판상의 솔더 범프 패드면상에안착된 솔더 볼들이 안정되게 그 배치장치의 요소들이 분리가 될 수 있도록 분리수단을 제공하여 솔더 볼을 배치하는 금속 마스크에 솔더 볼이 붙어 빠져나오거나 금속 마스크를 제거하면서 볼의 정렬 상태가 어긋나게 되는 경우가 발생할 경우에 이를 복구(repair)하는데 과다한 시간의 손실과 그 복구 상태 여하에 따라 조립 수율의 저하되는 단점을 방지할 수 있는 효과가 있다.The present invention relates to an apparatus and method for arranging solder balls on a printed circuit board of a ball grid array, wherein the arrangement of the components of the placement apparatus in alignment of the solder balls provides an alignment means, and the printing thereof. Solder balls seated on the surface of the solder bump pad on the circuit board provide a separation means to reliably separate the elements of the placement device so that the solder balls stick out or remove the metal mask on which the solder balls are placed In the event of a misalignment of the balls, there is an effect of preventing the loss of excessive time in repairing and reducing the assembly yield depending on the repair state.
