Hi Guys,

Could someone please help me out a little.

I need to know the current carrying capacity of the following VIAS.

1.      0.6mm ring  0.4mm drill hole
2.      1.0mm ring      0.6mm drill hole
3.      1.4mm ring      1.0mm drill hole

How many of the above would I need to carry

a.      1A
b.      1.5A
c       5A

With a standard ? plating thickness on a 5V digital board.

All help appreciated, a deadline threatens. 

Derek

PS. If someone could point me towards a calculator program / 
table for this type of calculation I would be thankful.
