Abstract

Embodiments of the present invention relate to a fixture design for pre-attachment package on package component assembly. The fixture design includes a plurality of pockets arranged in a N×M array. The plurality of pockets is sized to receive bottom packages. The fixture design includes global fiducials that are used to locate positions of the pockets on the fixture, and sets of local fiducials, with each set being specific to one of the pockets and used to refine the position of the location of a corresponding pocket. Each of the pockets can include one or more ear cuts for easy component placement and component removal. The fixture design can include a vacuum port for coupling with a vacuum source for drawing a vacuum to hold the bottom packages down. The fixture design can also include a cover that is used with the fixture to keep the components from being disturbed.
