Currently we need information on spacing for innerlayers and
outerlayer for using 48V. DC nominal voltage planes.
        There are guidelines in IPC-D-275, but we have had failures in the
past with this voltage and the suggested spacing.
        This product should continue functioning for at least 15 years.

        So far, I have not found out what the max. peak voltage will be so
any answers should indicate not only the spacing at this voltage, but a
volts/mil.
for 48V. and above.

        I would appreciate any input and the logic/experience behind your
recommendations!
