Abstract:
1. A microelectronic subassembly comprising: a dielectric substrate having a top surface being a major surface, the top surface including a first region and at least one peripheral region extending beyond the first region; a microelectronic element having a major surface confronting the first region of the top surface of the dielectric substrate, the microelectronic element having peripheral edges extending away from the major surfaces; a plurality of leads electrically connected to the microelectronic element having outer ends overlying the at least one peripheral region of the substrate beyond at least one of the peripheral edges of the microelectronic element; vertical conductors electrically connected with the outer ends of the leads and projecting upwardly above the at least one peripheral region of the top surface; and an encapsulant layer provided over the top surface of the substrate and extending continuously from at least the peripheral edges of the microelectronic element to surround the vertical conductors for stiffening the substrate at the at least one peripheral region of the top surface of the substrate, wherein at least one of the vertical conductors projects to a height above a top surface of the encapsulant layer.
