VPT Engineer V-SHIELD to Offer Superior Operation


VPT have engineered V-SHIELD packaging technology to provide superior operation, even during the most adverse scenarios.

As a global leader in power conversion solutions for use in avionics, military, space, and industrial applications, VPT understands the severe environments its products are destined to encounter.

Extreme temperature conditions and vibrations are just a few of the scenarios its DC-DC converters, EMI filters, and accessory power products may experience.

As rugged conditions pose a threat to the reliability and operability of power conversion devices, the company has engineered durable, high-performing packaging that offers exceptional product protection and functionality.

VPT’s products operate in challenging environments and are exposed to salt, air, pressure, and varying temperature conditions during board assembly.

V-SHIELD packaging is an advanced epoxy encapsulation, which is 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. V-SHIELD is designed to offer exceptional protection at a cost comparable to other high-reliability COTS solutions.

The packaging solution also features a unique and essential six-sided metalised shield to improve system EMI compatibility. With double-sided conduction cooling, the solution allows for simplification in system thermal design and creates 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.

The covering allows the converter to be used for military ground vehicles or commercial and military aircraft where severe vibration, shock and temperature cycling will be present.

Judges of the prestigious 2016 Military and Aerospace Electronics Innovators Awards programme awarded the packaging technology with its highest, platinum level award.

This celebrates military and aerospace electronics that feature superb innovation characterised by groundbreaking approaches to meeting needs, new levels of performance, efficiencies and / or ease-of-use.

When your programme needs true military-grade high-reliability DC-DC converters, EMI filters and other power accessories qualified to MIL-PRF-38534 Class H and Class K, count on...
Most power systems for high reliability applications can be constructed from standard power modules. The typical scenario requires various DC output voltages and power levels...
