2.3 Mask function
The mask function involves creating a mask area inside a step, and specifying whether or not to always detect
the created mask area when performing inspection. If, for example, the inspection status is "Parts Check", and
the printed characters on the top of the parts cannot be recognized, using this function, an inspection object
exclusion mask is created at the character position and inspection is performed. Furthermore, if the inspection
status is "Electrode Check" and the electrode and parts are detected simultaneously, inspection can be
performed by creating an inspection object exclusion mask in the center of the parts. This procedure describes
an example in which the inspection status is chip part "Electrode Check", the electrode and part are detected
simultaneously, and an inspection object exclusion mask is created in the center of the parts.
TIP
The mask function is valid for the following inspection statuses.
parts
check, electrode check, polarity check, character recognition, solder quantity check, lead check, position
align, brightness level, shape check
