6.5. Accept Mark setup

The bad mark refers to the mark indicated on the PCB to show whether a small PCB in the

array PCB is good, acceptable or defective. The bad mark is indicated for defective PCBs

while the Accept Mark is not indicated for defective PCBs. However, in the case of the

Accept Mark, part placement is performed only in the PCB with the Accept Mark.

If no small PCB proves to be defective in the array PCB, it is not necessary to set the

Accept Mark, which will otherwise waste time.

In such cases, if setup is performed to use a bad mark but it is not used, the machine will

waste time checking for the existence of the bad mark.

When this <Accept Mark> button is clicked on, the following dialog box for the editing of

accept mark data is displayed.
