Eagle Drill Sizes

Hi All,

 

I'm a student currently working on my senior design project. I have no PCB experience whatsoever and this project is my first experience doing a PCB design. I just submitted CAM files to Advanced Circuits to get a prototype board printed for my project (they have special pricing for students) and I got an email back with several errors found by a CAM Engineer. One of the errors include "This design has minimum drill size of .01181" that is less than AC minimum of .015" for $33 special. Please provide a revised drill file"  When I was doing my design I didn't think to adjust any drill sizes so I just used whatever Eagle gave me.

 

In Eagle Freeware, Is there any easy way to change the minimum drill sizes for all the holes under .015"? What is the process of doing this?

 

Thanks in advance!

Hi Tim

Firstly you need to identify where the under size holes are.

Are they in vias or are they in the footprints for the components?

If they are in the vias then you can change them on the board using the

methods the others spoken of. If they are in the footprints for the

components then they need to be changed in the libraries.

So the fastest way to crack this nut would be.

Inspect one via that looks to have a small drill hole and see if it is

undersize. If it is, determine what is a sensible size via drill for the

scale of your design and change all vias to that size.

At this point you will know your vias meet the 0.015 minimum

Next I would run the following ULP

statistic-brd.ulp

When it completes, look on the tab DRILL/HOLE

Look in the columns 'PAD drill' and 'VIA drill'

The values are in millimetres but you will be able to determine if you

have any holes under 0.015" (0.381mm)

Hopefully vias were the issue. If not, come back.
