Check each mating surface for nicks, scratches, flatness and surface finish. The heat dissipator mating surface should be flat within .0005 inch/inches and have a sur- face finish of 63 micro-inches. 2. It is recommended that the heat dissipator mounting surfaces be plated with nickel, tin, or silver. Bare alumi- * num or copper surfaces will oxidize in time resulting in excessively high thermal resistance. 3, Sand each surface lightly with 600 grit paper just prior to assembly. Clean off and apply silicon oil (GE SF1154, 200 centistoke viscosity) or silicone grease (GE G322L or Dow Corning DC 3, 4, 340 or 640). Clean off and apply again as a thin film. (A thick fiim will adversely affect the electrical and thermal resistances.) 4. Assemble with the specified mounting force applied through a self-leveling, swivel connection. The force has to be evenly distributed over the full area. Center holes on both top and bottom of the Press-Pak are for locating purposes only. HEAT SINK SELECTION MADE EASY The C440 specification sheet marks the introduction of two new characteristic curves which should greatly facili- tate heat sink selection. Figures 5 and 6 plot allowable average current versus ambient temperature and case-to- ambient thermal resistance for the two most frequently encountered waveforms, 1/3 duty cycle rectangular current and 180 sinusoidal current waveforms. As soon as the average forward current and maximum ambient tempera- ture are known, the designer can specify a heat sink thermal resistance. Note that the graphs span the range of heat sinks from water-cooled (Rgc4 = .03C/W) to free-air convection 5 of 5 175 Great Valley Pkwy., Malvern, PA 19355, USA (Reca = 0.3C/W). It is possible to linearly interpolate between the curves for Rgca. These curves have been derived from the following basic equation: Ty = Ta + Pave * Rasa where: Ty = 125C For increased reliability,.the usual practice is to derate T; 15-30 degrees, Figures 5 and 6 can perform this function by the simple expedient of raising T, by a like amount.
