Creative Materials has developed a line of products that are customized for LED lighting applications. Formulated for use in the manufacture of LEDs, these products are highly effective as an interface between a heat-producing component and a heat sink. We have developed some innovative solutions and several new products, including the following: 124-08A/B is a flexible electrically conductive two-part epoxy system, low temperature curing, with excellent thermally stability and shock resistance. B-Stageable epoxy adhesives include 125-22 (electrically conductive) and 122-07 (thermally conductive), which are both screen printable. A unique product, 125-50, White Reflective Solder Mask, is screen-printable and highly reflective.
The expanding industry of high power light emitting diodes (LEDs) provides a good example of the need for effective heat management. Heat removal in LEDs has become a critical focus for R&D efforts, since LEDs are rapidly replacing more traditional lighting methods. The heat generated by LEDs must be removed to ensure optimal performance. In order to extend the life of an LED device and reduce operating cost, the functional temperature must be kept below 120°C.
