-----Original Message----- From: Michael Biggs [mailto:[EMAIL PROTECTED] Sent: Monday, June 02, 2003 3:21 PM To: 'Protel EDA Forum' Subject: [PEDA] eight-layer stackup Anyone have a preferred method of stackup guidelines of web references to layer stackups for 8 layers using four power planes and four signal layers? I am torn between two methods being that I have two internal power planes. Thanks for any help! Also I have a couple of BGA's on this layout and when I run (using Protel99SE) my DRC everything is great other than the "dogbones" I had to route to the via on all the unused pins of the BGA. Any way to create rules for this so I do not get violations during DRC? Thanks again!
