ABSTRACT:
An integrated circuit package of the surface-mountable type within which a battery is mounted is disclosed. Battery leads extend from the side of the package body opposite that which is adjacent the circuit board when mounted, and between which a conventional battery may be placed. Standoffs are located on the package body for supporting the battery above the package body, so that a gap is present therebetween. A housing is attached to the package over the battery, and has standoffs attached to its inner surface so that a gap is also present between the housing and the battery. The gaps may be air gaps or filled with a low thermal conductivity material. The gaps thermally insulate the battery from the package body and housing, so that the circuit may be subjected to solder reflow mounting to a circuit board, while insulating the high temperatures from the battery.
