zSPREADER™ Passive Heat Spreader

Optimal spreader for discrete heat source cooling

Features and Benefits

  • Use of 500W/mK eGRAF natural graphite – better than copper!
  • Cu orAl rivet in direct contact with heat source –minimizes through thickness resistance
  • Optimized thermal contact between rivet and natural graphite
  • Can be used with standard single layer FR4 printed circuit boards as a replacement for metal core printed circuit boards (MCPCBs).
  • Can provide electrical isolation with minimal thermal penalty
  • Available in single or multiple layers of 0.75 mm natural graphite
  • Custom rivet configurations available

Product Description

eGRAF® zSPREADER™ thermal management products are designed to provide minimal thermal resistance for optimal cooling of discrete heat sources. zSPREADER products combine a sheet of high-performance 500W/m-K SPREADERSHIELD™ material with a copper or aluminum thermal via.  Applications include high power LEDs, CPUs, GPUs, solid state relays, and ASICs, where key operating temperatures have been reduced by as much as 46°C! As a cost-effective alternative to Metal Core Printed Circuit Boards (MCPCBs), zSPREADER designs are also effective in applications that inlcude LED Backlight Units, LED General Lighting, Automotive Electronics and Power Amplifiers.
