The equipment you're looking for is a Micro-Modifier. As I 
have been out of the fab side of PWB's for a while I do not 
recall the manufacturer, (maybe Bishop Graphics?). It works in 
the rotary motion you refer to.

In addition there are many conversion programs which will 
create gerber from drill data and vice versa. Most PWB 
suppliers should have this capability and pads can be modified 
as required for soldermask.

Help!

As I understand it, there is a standard piece of equipment 
used throughout
the pcb fab industry that will take a piece of film for a "pad 
master" and
create a piece of film for a soldermask. Pads end up .010-.015 
larger on new
exposed film. As I understand, this equipment has a motorized 
surface that
moves in a circular motion.

I hope this description is not to vague, but if you can tell 
me if such a
machine exists? What is it really called? And is that it's 
true purpose?

The problem is, we have lost many of our older gerber archives 
from an obsolete
cad system, and need to purchase more of these older boards 
from our previous
supplier. Our interest is, If our existing supplier can now 
supply these
pcb's with a soldermask, (they did not have soldermask 
before).

Is this much of a problem for pcb fabricators?

Thanks for your answers:
