This is the design guide I follow, that was specified to me by a vendor. It is not based on any standard that I know of, but it has worked perfectly everytime so far (meaning many many times). On a .062" board, the 30 degree score cut in from both sides is .021" deep, leaving a center section .020 +/- .004". I leave .030" free space from the score edge. On the .031" boards that I do, the numbers are halved, except for the tolerance. Hope this helps some.

Quality has a question? Thanks in advance. Paul Brionez Sr. PCB Designer Cherry Electrical Products 11200 88th Ave P.O.
