Abstract

A precision die-attach system and method are provided for precisely aligning and orienting multiple dies relative to one another and relative to a mounting surface and for attaching the dies to the mounting surface while maintaining the relative alignment and orientation. The system includes an alignment tool that is a precisely manufactured part having receptacles formed therein that are precisely aligned with one another. The receptacles hold the respective dies in positions and with orientations that are precisely aligned and oriented with the respective receptacles. Because the receptacles are precisely aligned and oriented relative to one another, the respective dies held therein are precisely aligned and oriented relative to one another. The die-attach system includes a mechanism for maintaining the precise alignment and orientation of the dies within the respective receptacles as the system places the dies on the mounting surface.
