Abstract:
1. A microfeature device package system, comprising: a microfeature device; a plurality of device contacts electrically coupled to structures within the microfeature device; a conductive structure at least partially enclosing a cavity housing the microfeature device and electrically connected to at least one of the plurality of device contacts, the conductive structure having a plurality of first and second package contacts, individual first and second package contacts having contact surfaces accessible for electrical coupling to at least one device external to the package, the first package contacts being accessible from a first direction for coupling and the second package contacts being configured to receive solder balls and being accessible from a second direction for coupling, the second direction being opposite the first direction; an encapsulant disposed adjacent to the microfeature device and the conductive structure, the encapsulant having apertures aligned with the second package contacts and containing solder balls carried by the second package contacts, the encapsulant being positioned against the conductive structure proximate to the first package contacts and including aperture walls extending outwardly from the contact surfaces of the second package contacts; and individual volumes of solder positioned at individual first package contacts.
