Tag: Thick copper circuit boards

Printed circuit boards for high current densities and efficient thermal management (1)

Thick copper, Iceberg® and HSMtec® are three different technologies for high current PCBs. The article compares the three technologies and explains the design possibilities, current carrying capacity and heat dissipation of the power semiconductors. Engine control adjusts speed, power and torque to demand and operating conditions and plays a major role in the energy efficiency

Iceberg® circuit boards

Iceberg® circuit boards are partial thick copper circuit boards with mixed copper thicknesses of 105 and 400 µm on the same level in the outer layers. In the process, about two thirds of the thick copper is sunk into the base material. The “sinking” of the thick copper structures in the base material enables a
