Latest Patents

One of Hoon's latest patents is titled "Interposer Based Test Program Evaluation." This invention includes a test system that features a printed circuit board and a switching interposer board. The switching interposer board consists of a probe point, a first bus, a second bus, and a set of switches. Each switch has a first terminal connected to a respective pin of an integrated circuit device, a second terminal linked to the first bus, and a third terminal connected to the second bus. The switches can operate in two states: one that couples a pair of pins of the integrated circuit device during a short test, and another that connects at least one pin to the probe point during a voltage level spike test.

Another significant patent is focused on "Testing Integrated Circuit Packaging for Shorts." This invention allows for the testing of an electronic package with an array of pins for shorts and continuity in a parallel manner. The pins are divided into groups, ensuring that no pin in a group is adjacent to another pin from the same group. Continuity is tested on one group while applying a reference voltage to the other groups. A separate current source is connected to each pin, and the resultant voltage is measured to detect any shorts between pins.
