Hi,


I have been looking in IPC-D-275 and RB-276 for design criteria for a
TDR coupon.  I could only find a reference to IPC-D-317..Which, of
course, I do not have.(had to order)..

Does anyone know if this spec. has the coupon construction information
(number of holes, recommended sizes, which holes hook to
power/ground/signal for the varieties of Impedance styles? 

Is there a standard coupon, or does everyone make their own as they go?


Thanks,
Doug Jeffery
