Hi Mike,

The bulk of the stuff I am seeing here generally looks like:

5 mil line & space
5 mil dielectric thicknesses of FR4 (Er = 4)
dual stripline inner layers/microstrip outer layers
1/2 oz copper (0.7 mil thickness)

Subject: [SI-LIST] : Board Data Needed

Hi folks. I would like to get some typical numbers for PC board RLCG
parameters. I am coming from the packaging side and I'm not familiar with
the latest board technologies. I can generate these numbers myself if you
have typical line width/spacing/thickness geometries, dielectric properties
(epsilon and loss tan) and dimensions. Any info will be appreciated.

Best regards,

Mike Lamson
