Just a little caution about simply adopting a recommended pad arrangement
for a component.  I have been burned by using a recommended pad size and
location without first laying a part on a 1:1 plot of those pads.  You may
want to use their recommended pads as a starting point, but I would strongly
recommend you confirm those pads against an actual part before you "call it
good".  You may want to massage those pads based on your process and
experiences.  A 1206 component is very common, but remember- not all 1206's
are the same.  Just my $.02  Lenny Carter, ERG, Inc.  www.ergpower.com
