West Conshohocken, Pa. – Heraeus Precious Metals, a world leader in industrial precious specialty metals and technology, announced that its Celcion® material system – including a dielectric, conductor, and solder mask – has been certified and received recognition status by Underwriter Laboratories (UL®), a global, independent, and non-profit product safety testing and certification organization.
“UL®’s recognition gives customers the assurance that our Celcion® material system meets the stringent safety and performance requirements of thermal circuit technology”, said Mark Challingsworth, Technology Director, within Heraeus Precious Metals’ Electronics Materials Division - Business Unit Circuits & Components. “Passing the certification test and meeting UL’s industry standard for flammability testing is the ultimate seal of approval. Knowing that the system has passed UL’s stringent testing; our customers can feel confident using the Celcion® system in their LED thermal substrate applications.”
As a result of the successful completion of testing by UL®, Heraeus Celcion® has proven reliable, safe and as a highly effective alternative to traditional metal core printed circuit board (MCPCB) manufacturing. Heraeus Celcion® passed some of the most rigorous tests in the industry to gain UL®’s recognitions, including:
• Recognition of Materials for use in fabricating UL recognized printed wiring boards
• Recognition for Solder Resist for physical, electrical, flammability, thermal, and other properties of the materials
Heraeus Celcion® is a thick film material system that was designed to produce electronic circuits for LED lighting on aluminum (Al) substrates. Celcion® is able to take the same fit, form and function as MCPCBs, but delivers an increased thermal conductivity and high-dielectric breakdown strength. This process incorporates a selective additive deposition that uses material only where it is needed, which results in less material consumption. By using a limited amount of material and removing interface materials, this reduces the thermal resistance and provides a more direct connection to the Al heat sink. Celcion® circuits typically run 10°C or more cooler than MCPCBs, which allows designers an increase in lumen power output and – thereby – reduces the number of LEDs needed by up to 20 percent. This solution decreases production costs and enables customers to add another material choice for high-power applications to their design kit, without sacrificing performance.
The Celcion® material system is ideal for use in high-power applications – including high-power LED substrates (>1W input) found in general illumination, signs, signals, and displays – with distinguished performance benefits in power electronics and heaters. With the UL®’s certification and recognition, the Heraeus Celcion® material system has proven reliable and satisfies customer and industry standards.
