(care should be taken to avoid upward pres- sure of the leads towards the lid). 5. solder leads in place using an sn63 type solder with a controlled temperature iron (210?). scale: board higher than lead. than lead. board lower not recommended application % of rated power 150 125 100 75 50 25 100 75 25 50 0 case temperature c
