About changing drillsize and not changing the lib

autodeskguest
autodeskguest over 16 years ago

Hi

 

I am etching a lot of PCB's my self and using 0,5mm drill for all drillholes

in Eagle. When I drill the hole on the final printboard I use the correct

dillsize according to each component. The reason for this is that it's very

easy to center the dill on the board when I'm using a 0.5mm hole on the

board, otherwise often the dill will be in the edge of the hole and not 100%

in the middel.

 

The problem is now: I have changed the drillsize on a lot of components in

my database to 0.5mm but if I want the have a PCB made by Olimex I can't

have 0.5mm drillsize on all the holes. At least that will be the problem if

I sent out the brd file directly to Olimex.

 

But how can I come around this? I will change the drill size in my database

back to the correct size on each component, but I would still like to be

able to make my homemade boards with 0.5mm hole when I do a kitchen table

etching and drilling.

 

Is it possible to make a gerber or similar file (I dont know anything about

gerber!) that could change the drillsize from the correct size and to my

0.5mm so I can print the board layout on my laserprinter and still preserve

the correct dillsize in Eagle?

 

Kind regards, Peter Andersen

    Hello Peter,

     

    There is a ULP made for this.

     

    You can design your lib parts with the correct drill diameter and

    layout your board. When you're finished run 'drill-aid.ulp'. It

    creates a new layer (116) with 'pads' overlapping the real pads,

    having a hole with a size that you can select. (ie. 0,5mm). When you

    print your board select this layer as an extra, if you make gerbers

    (or send your .BRD file) just leave it out.

     

    Regards,

     

    Richard

     

    Thank you SO MUCH for that! I have asked a lot of people about this problem

    and also posted on a eagle NG a couple of times - with no luck at all.

     

    You've just made my day!! ;.))) great!!

     

    Thank you so much - I just love that kind of things with Eagle image

     

    Peter
