Latest Patents

One of Nhon T Do's latest patents is a chip scale electrical test fixture with an isolation plate having a recess. This innovative test fixture grounds all of the solder balls of a ball grid array (BGA) of a chip scale package, except for a selected subset of the solder balls, to perform electrical characterization of the package. The isolation plate includes a recess ground into the plate, and a hole in the recess that permits access to the selected subset of solder balls. The recess provides clearance for a fixed compliant probe to land on the solder balls to be tested through the hole, and a probe contact surface for a ground portion of the probe to securely land.

Another notable patent is related to a heat sink grounded to a grounded package lid. In this invention, an integrated circuit package, which has an integrated circuit die, is mounted to a system board. The ground trace of the system board is connected to the package, which has a plurality of ground leads on its surface. An electrically conductive epoxy is placed on the ground leads and adheres the package lid to the package board, grounding the package lid. A heat sink is mounted to the package lid with an electrically conductive adhesive or electrically conductive slips that extend from a flange of the package lid to a flange of the heat sink to ground the heat sink.
