  I have attached a clip file from a version 15.5.1 Allegro layout I typically 
use. 

  I Exported the following items; Symbols, Pins, Vias, Lines, & Shapes.

  Import this clip file into a blank Allegro database using Mils as the User 
Units, with and Accuracy of 2.

  The area the clip needs to import to is about 3 X 3 inches.

  The small circles represent 10 mil non plated holes. You can measure and/or 
dimension the other necessary data.

  I would typically replicate this break-away tab every 1 to 1-1/2 inches. It 
is very sturdy and breaks cleanly.

  Let me know if you have any further questions.

  Subject: [PCB_FORUM] break-in tab diagram

   

  Hey guys,

   

  I find myself having to use break-in tabs after many years of not using them 
(lately I almost completely used scoring or no specified paneling with AMD).

   

  Does anyone have a diagram showing the details of a break-in tab?

  What I need is the routing path width (I think I used 125 mils), width of the 
tab and size and location of the break-in holes.

   

  Thanks for any help you can give me (in the mean time I'll keep searching on 
the net).

   

  Regards,
  Gary
