6.5.1.1 Teach Badmark...
TABLE 6-11
Before the system can perform successful badmark sensing, every badmark type
which has been specified in the action spec must have been taught to the system.
Once a badmark type has been taught to the system, this information can be filed
for future use.
Please notice that there are basically two ways to indicate a bad circuit:
■ By using a spot-type badmark (dedicated badmark).
The bad circuit is indicated by a sticker, a painted spot etc.
Typically this badmark exceeds the BVM camera’s field of view.
■ By using a fiducial-type badmark. In this case a fiducial was assigned for
badmark purposes; this fiducial has the function of a badmark.
The bad circuit is indicated by the presence or absence (being covered) of a
fiducial assigned as such.
Typically the fiducial-type badmark is smaller than the BVM camera’s field of
view.
Teaching the fiducial-type badmark is similar to the teaching of fiducials.
Before the badmark teaching can start, meet following conditions:
■ The board is present in the BVM section.
■ The action spec with the relevant badmark types specifications has been loaded.

Smallest Enclosing Rectangle
■ Select [Smallest Enclosing Rectangle]
■ Look at the monitor:
• For spot-type badmarks, check if the rectangle is completely covered by the
badmark; that means that the badmark should be larger than the rectangle
