Presently used solutions for Thermal management

? Aluminum is the obvious choice for
the housings however has the following limitations ( Alu 200 W/mK, Cu - 380 W/mK), Weight Cost ( ) Productivity Safety – Electrically Conductive Design limitations Thermoplastics can overcome all these challenges, however they are inherently insulators, , .
