Dear Phil and Gary,

        Thank you for both of you
You are right .When I've asked about this,I told  that we want some safty
factor for surge current , so should I calculate the trace width depending
on the maximum current value may be take place due to surge current, or
there is another way to calculate it?
Thanks in advance
Regards,
