Stop-Choc® copper cushions

The Hutchinson StopChoc® copper cushion fulfills several functions at once:

It ensures efficient heat transfer, compensates for tolerances, and protects sensitive components. Its design enables stable thermal conduction under variable installation conditions while reducing the transmission of mechanical vibrations. 

Function

  • Creation of a reliable thermal bridge
  • Reduction of thermal contact resistance
  • Compensation of tolerances between differing contact surfaces
  • Damping of mechanical vibrations without transferring them to adjacent components

Technical Features

  • Highly conductive copper material
  • Consistent heat transfer even under dynamic operating conditions
  • Manufacturing technology without loose wires
  • High cleanliness and robust mechanical design

Optionally, the copper cushion can be used in combination with external temperature sensors to provide optimal thermal coupling for measurement points.

Structure and Material

  • Material: High‑thermal‑conductivity copper
  • Mechanically stable design for secure integration into mechatronic systems
  • Manufacturing without free wire elements – increased operational safety

Applications

  • Thermal management in mechatronic modules
  • Automotive engineering
  • Electronic and sensor systems
  • Applications with combined thermal and mechanical requirements
