Clamp Selection
The choice of the clamp suitable for each different application can be made according to three main parameters. These parameters will help you choose between heat sink clamps, SCR clamps, diode clamps, rectifier clamps, thyristor clamps and other hockey puk clamps.
- Type of semiconductor (diameter and thickness)
- Requested clamping force
- Total clamping thickness (puk + heatsink web thickness)
Technical Characteristics
The bars of the clamps are machined out of cold rolled steel and plated with ROHS compliant Alodine 5200.
The cup shaped springs are made of steel UNI 50CrV4. Upon request they can be made of stainless steel.
The screws and bolts are made of steel class 8.8.
Insulator Properties
The insulators for the clamps are made of polyammide 6.6 with 50% glass fiber added. They have dielectric property of 85KV/mm. The thickness of the IB8 insulator is 1.7 mm, the IB10 is 2.7mm working temperature of 145 C.
