Shannan O’Shaughnessy, GVD Corporation, to present at SMTA Capital Chapter’s Expo and Tech Forum on August 24

The SMTA Capital Chapter is pleased to announce that Shannan O’Shaughnessy of GVD Corporation, will present “Reliability without Hermeticity: Commercial Vapor Deposited Coatings for High-Frequency RF Micro-Electronics” at the upcoming Capital Expo and Tech Forum at Johns Hopkins University / Applied Physics Lab, Kossiakoff Center, on Thursday, August 24th.

Radio frequency (RF) micro-electronics are used everywhere in today’s technology, from the internet of things to military radar systems. It is challenging for these advanced RF systems to meet size, weight, power and cost requirements set by consumer market or defense agency demand, what the military calls “SWaP-C”, due to the need for packaging of the RF components and integrated circuits (ICs) in to ensure long term reliability. Reliability concerns traditionally necessitate the environmental protection of these high-frequency RF devices at either the component or the assembly level by hermetically sealing the device in a bulky, heavy expensive metal enclosure to prevent degradation caused by hazards in device operating environments. Industry standard conformal coatings are unusable due to the significant signal degradation which occurs if applied directly over an RF circuit. There is a critical need for a coating alternative to which is compatible with high-frequency RF devices to provide a lower weight and lower volume environmental protection scheme with high reliability and negligible performance impact for RF devices. This approach would allow RF device integration on size, weight, and cost effective PCBs and eliminate the hermetically packaged chip-and-wire assemblies currently in use. To address this need, GVD Corporation has developed a high reliability environmental coating, Exilis, for RF electronics devices that can be applied to both the bare device and completed assemblies.

The SMTA Capital Expo and Tech Forum will be held at Johns Hopkins University / Applied Physics Lab, Kossiakoff Center, 11100 Johns Hopkins Road, Laurel, MD 20723. Registration opens at 8:00 AM and includes a complimentary lunch on the show floor. Exhibits are open from 9:00 AM until 3:00 PM and the first technical presentation will start at 9:30 AM.
