Drill a hole in the heat sink 0.499 + 0.001 inch in diameter. 2. Break the hole edge as shown to provide a guide into the hole and prevent shearing off the knurled side of the rectifier. 3. The depth and width of the break should be 0.010 inch maximum to retain maximum heat sink surface contact. 4. To prevent damage to the rectifier during press-in, the pressing force should be applied only on the shoulder ring of the rectifier case as shown. S. The pressing force should be applied evenly about the shoulder ring to avoid tilting or canting of the rectifier case in the hole during the press-in operation. Also, the use of & thermal lubricant such as D.C. 340 will be of considerable aid. TYPICAL THERMAL RESISTANCE. CASE , ll _01 Kom TO SINK.
