Is there a standard (such as IPC) or common industry practice in regards with x-out marking on rejected boards of a panel? Do board shops have to X-out both sides of the rejected board, or one side? If the answer is one side, which side should be ma

1: I use the fiducial mark as bad board mark. 2: First get the X sensor installed on the machine, then use method 1. 3: other methods: group boards according to which unit is X out. Then edit NC program to skip corresponding X out.

Dear all, Have anyone deal with X-Out boards? These defects are declared if one cavity or more from multi cavity boards are defective. There have been a request to use these boards in order to reduce the multi cavity board spoilage at supplier. Ho
