Latest Patents

Tanizawa holds a patent for a "Test fixture for providing electrical access to each I/O pin of a VLSI." This invention is designed for defining and performing functional tests, delay tests, and DC parametric tests on VLSI chips. The VLSI chip under test is mounted to a paddle card, which is detachably held under pressure against a circuit board mounted in a test fixture. A connector is sandwiched between the paddle card and circuit board, featuring insulated, spaced-apart conductors that provide electrical contact between each pin of the VLSI chip and a corresponding pad on the circuit board. Shift register circuits mounted to the circuit board correspond to each I/O pin of the device under test, functioning as input or output devices. This innovative design allows for efficient data transfer between the computer and the device under test.
