Heraeus Celcion®

Heraeus Celcion® is a thick film materials system designed to build circuits on aluminum substrates. Celcion® provides the same fit, form and function as traditional MCPCBs. But with improved performance benefits, such as reduced heat gain, your designers will be able to reduce the size of the Al heat sink and create new, streamlined design configurations, without sacrificing performance.

Traditionally, MCPCBs are constructed using a subtractive process, adding then removing material. This takes time and often wastes costly material. Celcion®, however, incorporates a selective additive deposition process flow—using material only where it's needed. The result is reduced processing steps, less material consumption and simplified bill of materials.

It has been independently verified to deliver industry-leading thermal connectivity and high dielectric breakdown strength, compared to traditional MCPCBs. All materials can be fired at less than 600°C, and it is compatible with 3000, 4000, 5000 and 6000 series aluminum substrates.

Because of Celcion's® unique additive printing process, not only will you reduce the processing steps, number of materials and amount of materials consumed, but your design team can also make quicker and less design changes than traditional MCPCBs.
By removing the thermal interface material altogether, Celcion® provides a more direct connection to the Al heat sink. This reduces the heat spreading layers and thermal footprint, allowing Celcion® circuits to run 10°C cooler than MCPCBs—performance you can actually see through a thermal gun.

Because Celcion® circuits run 10°C cooler, you'll see an immediate increase in lumen power. This means designers can reduce the number of LEDs needed by up to 20%—without sacrificing performance. With less LEDs needed, you can dramatically decrease your production costs.

Celcion® is ideal for high-power applications, including high-power LED substrates (>1W input) found in general illumination, signs, signals and displays. You'll also notice increased performance benefits in power electronics, heaters and auto manufacturing, to name a few.
