3.13 Bad Mark Detection
The bad mark detection is performed as follows:
① Move the X-Y axes to the bad mark detection coordinate. In this case,
when starting movement, the LED of the bad mark sensor is simultaneously
turned on.
② When damping of the X-Y axes is complete, the status of the bad mark
sensor is read, and execution or skip of the circuit is recorded. Then, the
LED of the bad mark sensor is turned off.
③ Steps ① to ② are repeated from circuit No.1 to the last circuit.
The order of the circuits subject to bad mark detection is the same as the one
for the BOC mark. For non-matrix split boards, the order of the number is the
one for the circuit location input from the board data input. For matrix split
boards, it is to be counted in an increasing order of the X axis at the side of the
circuit close to the machine origin of the X axis. This is repeated in increasing
order of the Y axis from the machine origin side of the Y axis. (See the figure
below.)
