Dear Sir,
 
I hope someone can advise me on the following:
 
Query on copper clearance to board edge
I was told that in standard it is:
Inner layer 20mils
outer layer 10mils
for v-cut boards
 
Is there any supporting document in IPC to specify that all PCB boards designed must have copper min 20mils away from the boards edge for inner layers and min 10mils copper away from the outer layer board edges? Hope to have your expertise advise. Thanks
