  • Patent number: 9630352
    Abstract: A method for manufacturing open cavity integrated circuit packages, the method comprising: placing a wire-bound integrated circuit in a mold; forcing a pin to contact a die of the wire-bound integrated circuit by applying a force between the pin and the mold; injecting plastic into the mold; allowing the plastic to set around the integrated circuit to form a package having an open cavity defined by the pin; and removing the open cavity integrated circuit package from the mold. A mold for forming a package for an integrated circuit sensor device, comprising: a bottom part for supporting an integrated circuit die; a top part that is operable to be placed on top of said bottom part to form a cavity into which a plastic material can be injected to form the package, wherein the top part of the mold comprises a spring-loaded pin arrangement comprising a cover that covers a sensor area on the integrated circuit die and provides for an opening when the plastic material is injected.
