Title: Innovations by Charles H. Casale
Introduction
Charles H. Casale is an accomplished inventor based in San Jose, CA. He holds 2 patents that showcase his expertise in high-speed signal testing and circuit board technology. His work has significantly contributed to advancements in the field of electronics.
Latest Patents
One of his latest patents is titled "Conductive dome probes for measuring system level multi-GHZ signals." This invention provides methods and apparatus for accessing high-speed signals routed on a conductive trace within a printed circuit board (PCB) using high-density interconnect (HDI) technology. The conductive trace is coupled to a microvia with a conductive dome positioned above the outer layer pad of the microvia. This design allows in-circuit test (ICT) fixtures or high-speed test probes to interface with the conductive dome, resulting in decreased reflection loss and other parasitic effects compared to conventional test points that utilize plated through-hole (PTH) technology.
Another notable patent is the "Dual stage in-circuit test fixture for circuit board testing." This fixture is designed for use with a circuit board tester and can move the unit under test (UUT) against a set of springs to a position where it contacts all probes of the tester for a first set of tests. A partial vacuum is created near the probes, allowing atmospheric pressure to move the UUT to the first position. The fixture includes a movable limiting member that engages in a way that limits the movement of the UUT when the vacuum is released, ensuring it only contacts the taller probes.
