Advancements in Electronics Packaging: How V-SHIELD® Offers Superior Operation

April 07, 2017 – As a global leader in power conversion solutions for use in avionics, military, space, and industrial applications, VPT, Inc. understands the severe environments our products are destined to encounter. Extreme salt, air, pressure, and temperature conditions are just a few of the scenarios our DC-DC converters, EMI filters, and accessory power products regularly experience. Some missions require these products to pass several screening levels to meet certain application needs. Because rugged conditions can pose a threat to the reliability and operability of power conversion devices, we’ve engineered durable, high-performing packaging that offers exceptional product protection and functionality.

At VPT we engineer power conversion solutions for use in avionics, military, space, and industrial applications. Our DC-DC converters, EMI filters, and accessory power products are destined to encounter severe environments and extreme salt, air, pressure, and temperature conditions. In order to provide superior operation even the harshest scenarios, our expert power supply innovators have engineered V-SHIELD® packaging technology.

V-SHIELD® packaging is an advanced epoxy encapsulation solution highly resistant to chemical, solvent and salt environments. It is fully compatible with high volume manufacturing processes including wave solder, cleaning solvents, high pressure sprays and aqueous wash processes. The packaging solution features a unique integral six-sided metalized shield to improve system EMI compatibility. It also simplifies system thermal design with dual sided conduction cooling, coupled with reduced power dissipation.

With V-SHIELD® packaging, the DC-DC converter combines the reduced radiated emissions advantage of the metal packaging and the water/chemical resistivity of the epoxy packaging. Merging these two options provides a design with superior performance at a reasonable cost. V-SHIELD® packaging allows the converter to be used for multiple rugged applications, from military ground vehicles to commercial and military aircrafts. It can withstand harsh environments including severe vibration, shock and temperature cycling.

Judges of the prestigious 2016 Military & Aerospace Electronics Innovators Awards program recognized V-SHIELD® packaging technology with its highest, platinum level award. The platinum level celebrates military and aerospace electronics featuring a superb innovation, characterized by a groundbreaking approach to meeting a need, a new level of performance, efficiency and/or ease-of-use.

V-SHIELD® packaging is designed to offer exceptional protection for effective product operability in rugged environments, at a cost comparable to other high-reliability COTS solutions.
