WTS001_p50-68 6/14/07 10:46 AM Page 67 Accessory Products THERMAL COMPOUNDS, ADHESIVES AND INTERFACE MATERIALS DeltaBond™ 155 DeItaBond™ 155is an epoxy adhesive formulated for use within the semiconductor industry. An easy to mix spread thixotropic paste, it offers high heat transfer, low shrinkage, and a coefficient of thermal expansion comparable to that of copper and aluminum. This adhesive is principally used to form thermally conductive joints in fabricated heat sinks and between heat sinks and power devices. When used to bond semiconductors to heat sinks, it also serves as an electrical insulator. Its strong bond to a wide variety of substrates resists severe temperature cycling. DeItaBond™ 155is only available in kit size. Simply squeeze out equal lengths and mix to uniform color. Shelf life: 1 year.
