1.27MM Hole Spacing

autodeskguest

Hi,

 

I'm trying to create a new device (with a new package) that is a simple 25

pin header. The pin spacing, however, is 1.27MM with a 0.75MM diameter pin.

 

When creating holes of 0.75MM in diameter spaced 1.27MM apart, I'm able to

size the pads the way I want to, without them touching each other (more that

0.005" of spacing, 0.127MM) . However, when I go to the device view with an

image of the package, it shows the pads are now touching each other, which

means all the pins are shorted together.

 

Is there something I'm missing, maybe a setting for a min diameter for a

pad?

 

Thanks for any help,

Nick.

    The minimum restring requirement is something the board manufacturer

    will tell you. If, at any place, your board violates this requirement,

    this will typically cause the board manufacturer to get back to you

    and tell you that this board can't be manufactured at all, or needs

     

    that's not true in any case.

     

    I can use some vias with smaller "restring" (or no "restring" at

    all) without any problem, and I want to be able to do so.

     

    But I want to be warned about this, and currently Eagle has no

    design rule check for minimum "restring". That's a severe drawback

    since version 4.

     

    After all, check and change must be separated nevertheless.
