Abstract:
1. A method comprising: populating a lead frame with at least one circuit component wherein the lead frame has a length axis and a width axis; protecting the at least one circuit component wherein at least one inner package is fixedly attached to the lead frame and covers the at least one circuit component, wherein the at least one inner package comprises at least one alignment indentation positioned over a lead frame outside edge, and wherein every lead frame outside edge is parallel to the length axis and perpendicular to the width axis; fixing a sensor and an interconnect to the lead frame to thereby form an inner assembly wherein the sensor and the interconnect are electrically connected to the at least one circuit component; positioning the inner assembly within a mold wherein at least one movable pin engages the at least one alignment indentation to hold the inner assembly in alignment within the mold; flowing plastic into mold wherein the mold is configured to cause some of the plastic to set and thereby hold the inner assembly in alignment with the mold; moving the at least one movable pin out of engagement with the inner assembly such that plastic flows into the at least one alignment indentation; waiting for the plastic to set and thereby produce a sealed sensor assembly.
