Hi Donald, What you first need to do is get some safety pins and then see how many you can get into the via. When you can't fit anymore into the via you count how many you put in and then you know the capacity of the via. ...sorry I couldn't resist.... It sounds like you may be trying to find out what the current carrying capacity of a via is? This can be found in a couple of books, or in the archives of the SI list. Here is are a couple of threads (links not clothes) to get you started.... 1. //www.freelists.org/archives/pcdlist/07-2002/ 2. //www.freelists.org/archives/si-list/05-2003/msg00038.html Craig -----Original Message----- From: Stradlin Donald [mailto:stradlin_03@xxxxxxxxx] Sent: Monday, June 23, 2003 12:42 PM To: si-list@xxxxxxxxxxxxx Subject: [SI-LIST] VIA Capacity Hi all, I had one question.
