Hi Folks,

I am wading my way through my first "Major" PCB design and I have a
couple of simple questions/requests  for you.

1/      Does anybody have a conversion table AWG to MILS to INCHES to
METRIC ?
        Or at least AWG to Metric. 

2/      And has anyone got a table of PCB drill hole sizes for different
PTH pin sizes.

3/      Also does drill oversize vary from one PCB manufacturer to
another or is the 0.006MIL 
        that my vendor uses pretty much standard.

I would appreciate any help that you could give.

Regards

Derek Wynne
