Looking for industry standards on component pad geometry layouts for 201,402,603,805,1206 and BGA's. Internet site/s preferred, others appreciated.

Thank you, Brian

Brian: Several things:

� Many CAD systems offer compliant pad design libraries � Look at IPC-SM-782 "Surface Mount Design And Land Pattern Standard" � Some times, component manufacturers have the best information about pad designs for their components. � IPC offers a pad calculator that you can use to tailor pad design to your specific requirements.
