With HSMtec LED PCBs you can brush the limitations of standard PCB technologies for LED applications.
The partial integration of solid copper components in classic FR4 PCBs enables maximum performance capacity and reliability – compared with PCB technologies such as metal core boards. And does so at the same time as offering maximum electrical and optical flexibility.
HSMtec PCB technology allows high-brightness LEDs, intelligent sensor-based lighting controls and driver electronics to be combined on a single multilayer board. The copper elements selectively integrated into FR4 PCBs guarantee the highest level of thermal performance for the LEDs, irrespective of the total number of layers required for the control electronics.
What is more, HSMtec enables the creation of self-supporting 3D PCB structures in order to obtain efficient and visually effective designs and creative products. If simple single-layer layout structures are sufficient – but instead very high thermal performance required – the copper IMS PCB is the ideal technical solution.
Hidden behind this description is direct and efficient heat management using HSMtec® PCB technology. Only in places where heat is generated by LEDs are solid copper elements integrated in standard FR4 PCBs. Direct metallic connection of the LED solder pads with the copper elements underneath is achieved by via technology. That enables direct and highly efficient heat dissipation through solid copper without insulating intermediate layers such as on conventional metal core PCBs.
- More than 3 times the thermal conductivity of aluminium IMS PCBs
- > 3.5 times the service life of aluminium PCBs
- Optional insulation resistance > 4 kV
HSMtec® PCB technology provides the optimum basis for the most demanding requirements and highest power densities.
The direct connection of all LEDs to solid, integrated copper on FR4 boards manages the heat highly efficiently, especially with hot spots, and dissipates it extremely quickly. Even with multi-colour arrays with even distribution of the LEDs, HSMtec® enables multi-layer structures without thermal performance losses..
- Power levels of up to 200 W per array
- Multilayer circuit layouts
2-in-1 multilayer boards
What about lighting controllers and LEDs on a single circuit board? High-brightness LEDs, intelligent sensor-based lighting controllers and driver electronics can be implemented on a multi-layer board using HSMtec® PCB technology. The copper elements partially integrated in FR4 PCBs guarantee maximum thermal performance for the LEDs – regardless of the number of layers required for the control electronics.
- LEDs and control electronics on one board
- Multilayer boards with the highest levels of thermal performance
Multi-dimensional PCBs are the key if you want to invest in flexible and efficient light and product design. HSMtec® PCB technology opens up unimagined possibilities thanks to the design scope and photometric versatility it offers. Self-supporting PCB segments allow the various LEDs to be individually orientated so that the design of lighting characteristics aimed at can be achieved with inexpensive standard optics. And the really good thing about it? The variably alignable board segments are very stable. Once the inclination angle has been set, it doesn't change even under strong vibration.

When designing and producing an LED PCB there is a large number of parameters to consider. That is why we advise you to talk to us at a very early stage of development. Through our online advice service or on-site workshops we can discuss the technical aspects and special considerations that such PCB types involve right from the start. We are also happy to help you with technical optimisation features or cost reduction measures.
