High current, thermal management and multidimensionality of PCBs.

HSMtec allows large copper cross-sections in the form of profiles or wires to be selectively embedded into standard FR4 PCBs. In this way, fine conductor structures can be combined, easily and cost-effectively, with high current connections and efficient thermal management for power components on a single board. The integration of embedded thick copper pieces also provides the ideal basis for the implementation of multidimensional PCB structures, thus reducing system costs.

Manufacturing process

The copper wires or profiles are bonded with the etched conductive pattern of the individual layers by means of a patented ultrasound method, to form a solid material connection. This allows for easy integration within a standard multilayer manufacturing process with subsequent compression of the individual layers. Copper elements with variable widths between 2 and 12 mm and individual lengths offer the greatest degree of flexibility in the high current layout and thermal design of the PCB. This allows a significant improvement in performance to be achieved, even with existing PCB designs.
