The copper elements partially integrated in FR4 PCBs ensure maximum thermal performance for the LEDs - regardless of the total number of layers required for the control electronics.
With HSMtec® LED PCBs, you can overcome the limits of conventional PCB technologies for LED applications. The partial integration of solid copper parts in classic FR4 PCBs enables maximum performance and reliability - compared to PCB technologies such as metal core PCBs. And all this with maximum electrical and optical flexibility.
High-brightness LEDs, intelligent sensor-based light controls and driver electronics can be implemented on a single multilayer PCB using HSMtec® PCB technology. The copper elements partially integrated in FR4 PCBs guarantee the highest thermal performance for the LEDs - regardless of the total number of layers required for the control electronics.
HSMtec® also enables the design of self-supporting 3D PCB structures in order to realize efficient and optical designs and creative products. If simple single-layer layout structures are sufficient - but very high thermal performance is required - the copper IMS PCB is an ideal technical solution.
This term stands for direct and efficient thermal management with HSMtec® PCB technology. Solid copper elements are only integrated into standard FR4 PCBs in places where heat is generated by LEDs. A direct metallic connection between the LED soldering surfaces and the copper elements underneath is achieved using via technology. This enables direct and highly efficient heat dissipation in solid copper, without insulating intermediate layers as is the case with conventional metal core PCBs.
HSMtec® PCB technology offers an optimum basis for the highest requirements and power densities.
The direct connection of all LEDs to solid, integrated copper in FR4 PCBs manages the heat highly efficiently, especially in hot spots, and dissipates it extremely quickly. Even in multi-color arrays with an even distribution of LEDs, HSMtec® enables a multi-layer layout - without any loss of thermal performance.
How about light controls and LEDs on one PCB? High-brightness LEDs, intelligent sensor-based light controls and driver electronics can be implemented on a multilayer PCB 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.
Multi-dimensional PCBs are the key if you want to rely on flexible and efficient lighting and product design. HSMtec® PCB technology opens up unimagined possibilities through design freedom and photometric flexibility. Self-supporting PCB segments offer the individual alignment of different LEDs and thus the targeted design of the light characteristics with cost-effective standard optics. The best thing about it: the flexibly alignable PCB segments are very stable. The once-set angle of inclination does not change even in the event of strong vibrations.
