Screen Printable Phase Change Materials Provide Greater Flexibility
This new product, designated as Honeywell PCM45F-SP thermal interface material, allows manufacturers to apply phase change materials in a variety of different shapes depending on the shape of the chip design, also known as the screen print of the chip. Until now, manufacturers have been limited by the shape of phase change materials supplied in traditional tape formats.
"This new material meets significant industry challenges while providing flexibility so that our customers can optimize its use during the semiconductor packaging process," said Dmitry Shashkov, metals business segment leader for Honeywell Electronic Materials. "Our materials development programs are driven by listening to our customers and then offering new materials that provide them with value."
Honeywell introduced the material at the Semiconductor Thermal Measurement, Modeling and Management Symposium and Exposition, which was held March 12-16 in Dallas, Texas.
Thermal management has become a critical issue for the semiconductor industry as manufacturers seek to dissipate the tremendous heat generated by today's high-powered chips. If this heat is not dissipated, it shortens the life of computer chips and may cause them to cease functioning altogether. Honeywell helps chip manufacturers solve thermal management problems with materials that either conduct heat away from the chip to some other area or provide a means by which heat can be dissipated into the surrounding air.
Phase change materials are heat conductors which change phase from a solid, to a semi-solid or liquid state. This phase change allows these materials to fill the micro-gaps between the chip and the material, thereby providing a more effective and efficient means to transfer the heat away.
Traditionally, such phase change materials have only been available in a tape format, with the materials supplied on a roll. Small pads of the material are then affixed to the desired area during the semiconductor packaging process. The new screen printable format allows manufacturers to apply the material in a wide variety of different shapes, depending upon the screen print design used by the manufacturer to layout the design of the semiconductor chip.
