HUNT VALLEY, MD – January 15, 2009 – Reactive NanoTechnologies, Inc. (RNT), developer and manufacturer of its patented NanoFoil®, today announced that it has developed its NanoBond® process for use as a Thermal Interface Material (TIM) in Concentrated Photovoltaic (CPV) solar systems. As part of this development, RNT has issued an Application Note, available at www.rntfoil.com to assist users in applying this new process.
In this application NanoBond®, a joining process using NanoFoil®, can be used to replace traditional adhesives for improved thermal management at the TIM1 interface in CPV receiver applications. This is accomplished by joining thick, stress-absorbing solder layers together using NanoFoil®. The use of solder material as a replacement for traditional adhesives to bond the dissimilar materials of ceramic substrate to metal heatsinks improves thermal conductivity, providing lower junction temperatures (Tj max) which results in improved efficiency and longer lifetime of products.
“In a typical CPV receiver material stack-up, the interface between the ceramic substrate and the Copper or Aluminum heatspreader creates a large CTE mismatch,” explains Carmen Mattei, Product Manager for RNT. “By replacing traditional adhesives with a thick bond line of solder created using the NanoBond® process, RNT has developed a method for handling that mismatch, improving the thermal conductivity and allowing CPV manufacturers the opportunity to improve system performance.”
