Abstract
A method of making a microelectronic package includes providing a substrate having a plurality of conductive leads at a first surface of the substrate. The conductive leads may have first ends permanently attached to the substrate and second ends remote from the terminal ends, the second ends being movable relative to the first ends of the leads. One or more microelectronic elements having contact bearing surfaces and back surfaces remote therefrom may be juxtaposed with the substrate and the contacts connected with the first ends of the leads. A substantially rigid plate may be attached to the back surfaces of the microelectronic elements. The substantially rigid plate may be moved to a precise height above the substrate to vertically extend the leads. While the plate is maintained at the precise height above the substrate, a spacer material is dispensed between the plate and the substrate. The spacer material is then at least partially cured for holding the plate at the precise height above the substrate.
