Patent number: 6143076Abstract: Heat sinks and electrical components pre-coated with a layer of a material such as thermal grease are disclosed. Contamination and migration of the thermal grease is substantially reduced by covering the coated areas with a release liner that is removed prior to the assembly of the heat sink into a circuit board or other assembly. By providing a pre-coated heat sink, productivity can be enhanced by increasing accuracy with which the thermal grease is applied, thus eliminating waste and clean up. Methods for pre-coating either a heat sink or the release liner with thermal grease are also disclosed. In preferred embodiments areas of the heat sink can be either fully coated, or portions electively coated, and the coating is most preferably accomplished by pushing grease through an applicator head that has numerous small nozzles.Type: GrantFiled: June 18, 1997Date of Patent: November 7, 2000Assignee: Thermalloy Inc.Inventors: Jay Rasmussen, Matthew C. Smithers

Methods for pre-coating either a heat sink or the release liner with thermal grease are also disclosed. In preferred embodiments areas of the heat sink can be either fully coated, or portions electively coated, and the coating may be accomplished by a silk screening or pad printing process, which includes using an applicator head. The release liner is preferably provided with a pull-off tab to facilitate the removal of the release liner.Type: GrantFiled: June 18, 1997Date of Patent: May 9, 2000Assignee: Thermalloy, Inc.Inventors: Howard G.

Patent number: 5897917Abstract: Heat sinks pre-coated with a layer of a material such as thermal grease are disclosed. Contamination and migration of the thermal grease is substantially reduced by covering the coated areas with a protective film that is removed prior to the assembly of the heat sink into a circuit board or other assembly. By providing a pre-coated heat sink, productivity can be enhanced, by increasing accuracy with which the thermal grease is applied, thus eliminating waste and clean up. Methods for pre-coating either a heat sink or the protective film with thermal grease are also disclosed. In preferred embodiments areas of the heat sink can be either fully coated,, or portions electively coated, and the coating is most preferably accomplished by a silk screening or pad printing process. The protective film is preferably provided with a tear off tab to facilitate the removal of the protective film.Type: GrantFiled: August 13, 1997Date of Patent: April 27, 1999Assignee: Thermalloy, Inc.Inventors: Howard G.

Patent number: 5428897Abstract: A mounting spring clamp for securing a heat sink to a device package is secured to the heat sink by positioning the central body portion of the spring clamp in an attachment clip. The clip is compressed and positioned in a groove of the heat sink. The clip comprises a semi-circular shaped seat with ears extending from both sides of the seat and is made from a flexible material. Compression of the ears reduces the seat diameter, thereby trapping the spring's central body, and also creates spring force in the ears, thereby trapping the clip between the fins of the heat sink. The mounting spring has an elongated body with ends extending from the axis of its central body. The ends may be trapped or hooked in appropriate receivers on a frame or socket holding an electronic device package to secure the heat sink adjacent the device package.Type: GrantFiled: September 29, 1994Date of Patent: July 4, 1995Assignee: Thermalloy, Inc.Inventors: William D. Jordan, Matthew C. Smithers
