Latest Patents

Hathaway's latest patents include an "Ultra Wideband BGA," which is an electronic device packaging assembly designed to operate from DC up to 50 GHz with minimal parasitic losses. This packaging assembly features a thin base plate made of a suitable rigid material, with power vias, signal vias, and ground vias formed through the base plate to connect to traces, circuit components, and/or the device within the assembly. Additionally, an impedance matching compensation network is included to ensure proper impedance matching between the device and the signal vias. The ball grid array consists of multiple solder balls, including ground, signal, and power solder balls, all electrically coupled to the appropriate vias extending through the base plate.

Another significant patent is the "Process for Fabricating a Photonics Package and for Aligning an Optical Fiber with a Photodetector Surface During Fabrication of Such a Package." This process involves securing a ferrule to an optical fiber and inserting it through a movable flange into a photonics housing containing a photodiode. The ferrule is then adjusted longitudinally to position the optical fiber's end with respect to the photodiode surface. The assembly is further adjusted laterally and secured to the housing using hot gas injection or laser soldering, allowing for precise final positioning.
