Product Spotlight: Conduction Cooled Assemblies (CCAs)

Performance and Dependability: High-Performance Conduction Cooled Assemblies for VITA Designs. Overcome the Toughest Engineering Challenges with nVent SCHROFF.

Partner with our Design Team Support and Engineering Experts to solve thermal challenges through thermal analysis to speed up the prototyping process before any metal is cut. We offer simulation and modeling, component and board temperature measurements, and Card-Lok and Wedge-Lok interface temperature measurements.

We've simplified the supply chain for our CCAs. We've made it possible to manage your entire conduction-cooled assembly with one part number!

We've also created the High Thermal Integrated CCA by machining our High Thermal Sawtooth (HTS) Card-Lok directly into the CCA frame resulting in up to 40% increased thermal performance. 

Watch our CCA design process - we'll walk through the process from start to finish including:


  • Comprehensive consultation from the very beginning.
  • Ability to work with existing board, frame, or chassis designs
  • CAD templates and 3D printed prototypes available
  • Thermal design, simulation and analysis services
  • Over 60 years of experience as an industry leader in board retention and cooling
