Metal PCB

There are many terms for this category of PCBs; Aluminum Clad, Aluminum Base, Metal Clad Printed Circuit Board (MCPCB), Insulated Metal Substrate (IMS or IMPCB), Thermally Conductive PCBs, etc. but they all mean the same thing and perform the identical way.

Benefits of Metal PCBs

  • Intensely Higher Heat Dissipation (superior to standard FR-4 constructions)
  • More Conductive Dielectrics with Reduced Width (typically 5 to 10 times as thermally conductive as conventional epoxy-glass and a tenth of the thickness)
  • Exponentially Efficient in Thermal Transfer (more capable than a conventional rigid PCB)
  • Competent to Use Low Weight Copper Layer (able to use lower copper weights than suggested by the IPC Heat-rise charts)
