POWER ASSEMBLY CAPABILITY

The Power Assembly group was set up to provide a support service for those customers requiring more than the basic semiconduc-tor, and has developed a flexible range of heatsink / clamping systems in line with advances in device types and the voltage andcurrent capability of our semiconductors.

We offer an extensive range of air and liquid cooled assemblies covering the full range of circuit designs in general use today. TheAssembly group continues to offer high quality engineering support dedicated to designing new units to satisfy the growing needs ofour customers.

Using the up to date CAD methods our team of design and applications engineers aim to provide the Power Assembly Completesolution (PACs).

HEATSINKS

Power Assembly has it’s own proprietary range of extruded aluminium heatsinks. They have been designed to optimise the

performance or our semiconductors. Data with respect to air natural, forced air and liquid cooling (with flow rates) is available onrequest.

For further information on device clamps, heatsinks and assemblies, please contact your nearest Sales Representative or thefactory.
