Cool. Ok, say about 14x14 inches square planar. And I should mention that the intended dissipation point would be on initial insertion and would be through a 10Mohm resistor or so. The pin is the last resort just in case the other drain methods don't work due to some strange proliferation of an insulative coating :).

David Pommerenke -----Original Message----- From: David Heald [mailto:[email protected]] Sent: Thursday, October 31, 2002 4:58 PM To: '[email protected]' Subject: Circuit pack ESD drain All, Does anyone know of a sample waveform or general characteristics for worst case V&I on an ESD drain pin when a circuit pack is inserted into an equipment shelf? This is an odd question I know, but my management asked for the info and I really have no idea (and it "shouldn't" happen anyway ;o) I guess even a typical maximum charge that can be expected to be on a circuit pack would be sufficient information.
