Hi everyone,

 

I am working on 8-Layre stack-up board in PADS layout. I have blind VIA (L1-L2) and Buried Via (L2-L3). when I stacked blind and buried VIA, am getting Drill to Drill error.

can anyone please advice me to overcome this DRC.

 

Example:

Error   1 Location 685.75,1307.36 Level 7

Distance between drills too small:

VIA(685.75,1307.36), VIA(685.75,1307.36) distance is less than 4
