Latest Patents

Caballero is credited with 1 patent. Her patent, “Laminate Substrate-Based Differential Pressure Sensor Package Combining Air Cavity Channel Substrate, Overmold, and Lid with Two Chimneys,” describes a sensor device built around a substrate with a channel between its upper and lower surfaces. Two port holes connect the upper surface to the channel.

The package places an application-specific integrated circuit (ASIC) die on the substrate without covering the port holes. An overmold covers the ASIC and forms separate cavities around the ports. A transducer sits in the first cavity, electrically connects to the ASIC, and covers the first port hole. A lid attached to the overmold includes two chimneys. Together, these features define a compact package for differential pressure sensing.
