Problem: We are bringing 120VAC RMS (170Volts peak) onto a PCB via a 40 pin
dual row right angle header that is .025 square pins on .100 centers.  Six
pins are used three each of ACHOT and ACNEUT. We are also bringing 90VAC RMS
(130Volts peak) in on 18 of the pins. {This is a synchro/resolver
application, Low current ~ 2.0 mA}. 12 of the pins are ground and then 4 low
level signals.
 It appears the IPC-2221 spec. indicates that for top and bottom layer
clearances we need to maintain .050 clearance (this is where the pads would
be exposed).

Question: How do I maintain proper clearance to meet the spec.? Or is it
advisable to use a different connector and if so what is recommended?

Thanks for your help!
