(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 (210?c). scale: board higher than lead. than lead. board lower not recommended application specifications pa rt number attenuation (db) tol.
