IN PADS THE FACTOR IS STATED AS 14 PIN IC EQUIVALENTS PER SQUARE INCH. -----Original Message----- From: McGlaughlin, Jeffrey A [mailto:[log in to unmask]] Sent: Friday, March 02, 2001 9:44 AM To: [log in to unmask] Subject: [DC] Board Density Factor I was recently ask to explain the board density factor calculated by our layout package. It gave a factor of 0.1 sq. in./14-pin DIP. I translated that to be 140 pins per square inch so that it made more sense in the two sided surface mount arena, but was left wondering if there was a better way of figuring board density. What are you using and why? Jeffrey A. McGlaughlin, C.I.D.
