IMS printed circuits (copper or aluminium)
IMS printed circuits are circuits containing a fine layer of thin dielectric material (typically epoxy based) that transfers heat. This layer is placed over a metal base which can be copper or aluminium and it has high thermal conductivity to dissipate heat produced by electronic components. And a thin layer of copper is placed over this dielectric material for placing components. This type of circuit has various applications, including: energy converters, high power LED, street lights, car industry, voltage regulators, etc.
The main advantages of this type of circuit include:
- Heat dissipation is drastically greater than standard FR-4 constructions.
- The dielectric materials used are typically 5 to 10 times more thermally conductive than conventional epoxy glass.
- Thermal transfer is exponentially more efficient than a conventional rigid PCB.
