Thorough and complete DRC rules for PCB Design and Manufacture

[gigahertz]

Hello,

Is anyone aware of a very thorough list of design rules published that goes above and beyond of what can typically be found under a list of fab capabilities?

Something like a huge list of what is typically checked, and with standard rules and "advanced capabilities" rules.

I have plenty for the typical line widths and air gaps but want to find something even more in depth such as:

- min dist of silk to bare copper

- hole edge to pcb edge clearance

- max hole size for soldermask plug via

- etc. (there are many many many more checks done)

A complete list would be very helpful to many. Even if a designer follows the "capabilities" of their particular chosen fabricator, there are still many possible DRC errors that can slip through. If anyone knows of such a list, please share. If such a list isn't in existence, I'd be interested in working with a few designers to come up with a ultimate list and share. Worldwide input welcome. Any units welcome too.

Have a great day

hi
for hole center to board center must be 5.08 mm

I think some of the minimum distance changes with time!!! As the fab process advance, the distance shrink!!! I don't think you have a minimum standard on a lot of them. The best is still ask the fab house. I fab some boards on ebay for dirt cheap, their requirement is way larger than the state of the art place, but you are going to have to pay more for that. For example, their minimum trace width is still 7mils!!! I have been doing 7mils over 25 or 30 years ago already. But I can get 5 2"X3" 2 layer for $50US!!!

Contact your PCB fabricator and ask them about their capability.
You can create your design rules based on this information.
