IPC-D-275 has been superceded by IPC-2221A. Section 6.3 of IPC-2221A, Generic Standard on Printed Board Design, has the voltage clearance calculations for various configurations of rigid circuit boards. -Harry At 12:40 PM 12/13/2006, you wrote: >OK, > I guess I didn't really include the attachment.
