American Standard Circuits, Inc. Receives Second Technology Patent
ASC receives first patent for metal-backed Printed Circuit Boards
Chicago, IL July 7, 2009: American Standard Circuits, Inc. (ASC) reported it has received its second
technology patent from the United States Patent & Trademark Office.
U.S. Patent 7,540,081 covers Thermasil Film which is used to bond high or low frequency printed circuit
boards (PCB) to a metal heat sink with a thermally conducting electrically insulating silicone based film.
Thermasil can be made to any thickness from 3 mil to 25 mil and thermal conductivity can be tailored from 1.5 to
4.5 W/mK. ASC will license this technology to companies and fabricators interested in using this technology.
“ASC has a successful track record in developing technology solutions for its customers. This invention continues
to highlight ASC’s commitment to advancing technology and enhances our Thermal Management Solutions portfolio.
This complements our Electrasil offering which is both thermally and electrically conductive. Thermasil provides
customers with cost, performance and quick delivery advantages. Laminates of any size can be custom made. Our R&D
team continues to work on green technologies, specifically, in the areas of LED and Solar technology,” said Anaya
Vardya, CEO of American Standard Circuits, Inc.
Dr. Sandy Kumar, one of the co-inventors of Thermasil film,
believes that Thermasil is ideally suited for critical thermal management in LEDs, power electronics, defense,
telecommunication and solar photovoltaic technologies. PCBs bonded with Thermasil to the heat sink can quickly
dissipate the heat from electronic devices without making any electrical contact to the heat sink. This
interfacial film is stable up to 600 oF. Thermasil can also be made in putty form to fill in complex shapes and
air cavities. Another variant of Thermasil is where components need to be quickly assembled-disassembled and
permanent bonding is not allowed.
