Hello, I have a problem about plastic small outline package type. I could not find the recommended footprint for two devices which are having SO8 and SO20 packages. Is there any one who knows to calculate the footprint values? Or, is there a standart I could use to solve this problem? I could not find aanything from IPC-SM-782A. Am I in a wrong way? I would be waiting for your answer. Best Regards, Þefika Özkal Electronics Engineer ASELSAN Inc. Microelectronics, Guidance and Electro-Optics Division Electronic Design Address : P.O.
