Press-pack high power semiconductors are the key part on many applications or converters controlling electrical power. To use their full potential a proper mechanical design and optimal clamping of the whole assembly, the stack formed by the press-pack high power semiconductors, heat sinks, bus bars and other components, is paramount.
Rectificadores Guasch mounting clamps uses a single bolt tightening system with a precise pre-calibrated center force indicator. The correct force is achieved when the indicator washer with a lead located on the calibrated pressure system bolt can be slightly moved.
These pre-calibrated force indicator avoids any need for special gauges or torque wrenches during the mounting process.
A proper clamping is essential to the performance and lifetime of press-pack semiconductors, usually a 10% margin between optimal pressure is required and a good pre-calibrated clamp is needed.Our range of clamps are designed and calibrated with an extreme care to meet and exceed the most demanding manufacturer’s requirements.
An insufficient clamping can cause incorrect operation of the semiconductor being used and premature failing of the device, an excessive pressure or a poor or uneven pressure distribution will lead to deformation of the housing and internal stress causing it to fail prematurely during load cycling.
All our clamps range used along with our heatsinks range for press-pack devices are designed to achieve the best performance and the perfect assembly for this range of power semiconductors.
