“HSMtec” - Intelligent FR4 PCBs

HSMtec PCBs make it possible to override the existing limits of conventional PCB technologies for LED applications. The selective embedding of thick copper pieces in conventional FR4 PCBs allows the highest levels of performance and reliability to be achieved compared to PCB technologies such as metal core boards, while at the same time enabling maximum electrical and optical flexibility.

thermal management functional principle

With HSMtec, individual requirements can be implemented economically and in a tailored fashion, using low-cost standard materials and processes. The complete integration of all thermal, electrical and mechanical properties in a single HSMtec PCB thus results in a significant reduction in system costs compared to metal core and FR4 board designs.

HSMtec also makes it possible to create self-supporting 3D PCB structures for the implementation of an efficient optical design and creative product design.

Thermal via FR4 PCBs

For high levels of economy and tight budgets, we can offer you standard FR4 boards with thermal via technology, which are preferred for use in low to medium LED thermal performance categories. Copper plated through holes provide efficient thermal management in double-sided or multilayer FR4 PCBs.

Plugged thermal vias

Thermal vias filled with heat conducting paste allow copper plated through holes to be positioned directly below the LEDs, which results in a higher thermal conductivity than with traditional thermal via FR4 PCBs. At the same time, this guarantees easy further processing of the LED boards with standard processes.
