Dear Technet-ers,
 
We, at development ASML, have some discussions and questions about the
interpretation of chapter 6.3 electrical clearances and in particular
for highvoltage (700Vac). 
 
Question regarding to IPC-2221 :
1) Are the electrical conductor spacings as mentioned in table 6-1 based
on a testvoltages ? (for example 2100V testvoltage)
2) Must  i design , my board, on the testvoltage (2100V) or on the
working voltage ?
3) Is there a relationship between IPC-2221, 6.3 and the IEC60950 ? and
if "yes" where can i find this relationship?
4) Can i use the same highvoltage rules for Flex-boards?
 
Is there anyone how can help me? , thanks in advance.
 
Best Regards,
