1. make sure that the devices are mounted on flat surfaces (.001" under the device) to optimize the heat transfer. 2. drill & tap the heatsink for the appropriate thread size to be used. 3. coat heatsink with a minimum amount of high quality silicone grease (.001" max. thickness). 4. position device on mounting surface & secure using socket head screws, flat & split washers. torque screws to the appropriate value. make sure that the device is flat against the heatsink. (care should be taken to avoid upward pressure of the leads towards the lid). 5. solder leads in place using an sn63 type solder with a controlled temperature iron (700?). aluminum nitride terminations model RFP-60N50TP t ypical performance 2 sales desk usa: v oice: (800) 544-2414 fax: (315) 432-9121 sales desk europe: v oice: (+44) 23 92 232392 fax: (+44) 23 92 251369 power derating suggested mounting procedures suggested stress relief methods (2 places) board lower than lead. .025 scale: none min. with lead. board even not recommended application than lead. board lower scale: none board higher than lead. case temperature ? c % of rated power 150 125 100 75 50 25 100 75 25 50 0
