I am a QC person,

I have one doubt about back drill,

we have high speed signals list,

and all signals are manually checking back drill with back drill chart.

If any report is found to take signal wise report for back drill.

kindly please inform anybody,

thanks,
karthik

Allegro PCB High-Speed Option allows
users to specify which vias on critical
high-speed signals should be back drilled
to avoid reflections. An output report—
Backdrill NC and Legend Files from
Bottom, Top, or Any Layer if backdrilling
the inner core(s) of the PCB—allows users
to send backdrilling instructions to their
PCB manufacturers.

Otherwise must be manually checked.

Hi SunnySkyguy ,

regards,
karthikeyan
