Restring Tolerance Compliance

autodeskguest
autodeskguest over 18 years ago

I've been spending the better part of today wasting tons of my company's

money trying to save a buck - it's not making much sense for this

one-time, but I am also hoping this investment will increase my

understanding and either find me a more cost-effective board house or

give me the ability to better test my boards against the various houses

to see who is cheaper in each case.

 

On to the real problem at hand.  I've perused the board and found a few

complaints about the DRC's insistence on CHANGING restrings (annular

ring - as it SHOULD be called because I never stringed anything in the

first place in order to need to REstring it!).  Apparently the DRC even

does this if you have NOT set your pads in your libraries to AUTO.  Even

more dumber.  All this being really bad, to add insult to injury I

really do not CARE what percentage of annular ring I have aorund my

pads, every board house I've look at simply cares about the differential

diameter.  It wouldn't matter to them if I had a via the diameter of a

human hair or one the size of the Himalayans - they want one thing: a

specified amount of diameter LARGER than the drill.  It's not a

percentage, its a hard and fast number.  Why can't EAGLE accept a

percentage, a calculation, or a hard-and-fast value??

 

Suggestion for change?!

    Then set the minimum restring to the 'differential diameter' and percentage

    to 0%, for example, 6mil min and 0% generates an annular ring 12mil larger

    than the drill diameter in all cases, unless a larger diameter was set in

    the library device.
