Hello, I am planning a PCB test structure board, primarily to validate my tools, models and design rules for PCB xtalk, discontinuities (e.g. via backdrilling) various SMA connector types, impedance controlled vias, etc. etc. Any suggetions, hints or bits of wisdom you may wish to send me is appreciated as this is my first dedicated test fab and I would like to minimize the "should-have, could-have, would-have" effect (notice I did not say eliminate, but minimize %^) Thx, Jim - Jim Antonellis janton@xxxxxxxxxxxxx Sandburst Corp www.sandburst.com Office: 978.689.1669 Cell: 978.618.4745 This message and any attachments are Confidential and may be Legally Privileged.
