Hi, Brian
30 deg. is one common angle for .062" thick standard FR-4, but 45 deg.,
60 deg., and 90 deg. angles are also used. This information is detailed
in IPC 2222 section 5.3, and depicted in Table 5-1. It is also described
in less detail in IPC-610 and IPC 6012.

30 deg is very standard in the scoring industry. The larger the angle
the more edge distance you will need.

Subject: [TN] V-Score Standards?
Are there any industry standards for the angle of the V-score? Our
equipment
supplier suggests 30 deg. but some of our PCB suppliers say they don't
have
30 deg blades.
Thanks in advance,
Brian
