Details of Vision Processing Modes
Mode Applicable Components
Chip CPL Standard chip components such as chip resistor, chip
capacitor, network resistor, MELF resistor, MELF diode, etc.
Electrolytic Capacitor Components with two reflective ends, such as electrolytic
capacitor.
Edge-midpoint Search
(for old data/special
component)
Process speed is fastest, but rotation accuracy will be a little
bit lower than CPL.
This was used for standard chip before CPL is added.
Thinking of old data, when image error happened, retry will
be done by CPL process.
To create a new data, use this mode if CPL mode is not
available. Components of 3mm or more in size.
Overall Chip Process
(for old data/special
component)
Practically rectangular components (aspect ratio should be
1:1.5 or more). For heavy loading process of this, process time
will be longer.
To create a new data, use this mode if CPL mode is not
available.
Corner Search
(for special component)
Components with four right angles. Use this mode if CPL
mode is not available, especially for such special component
that can be recognized at corners only.
Edge-midpoint
Search(Non Recovery)
(for old data/special
component)
“Edge-midpoint Search” without Auto-recovery by CPL.
To create a new data, use this mode if CPL mode is not
available. Components of 3mm or more in size.
Glass Melf
Cylindrical-shape-glass-encapsulated components with
two reflective electrodes at the ends.
This is used for components with two reflective electrodes
at the ends.
Transistor Top Transistors with one lead on one side, and two or three leads
on the other side. The transistor is viewed with the one lead
upward on the monitor.
Right The transistor is viewed with the one lead rightward on the
monitor.
Bottom The transistor is viewed with the one lead downward on the
monitor.
Left The transistor is viewed with the one lead leftward on the
monitor.
Pow. Tr. Top Power transistors with one flat lead (large electrode) on one
side, and 2 or 3 leads on the other side. The transistor is
viewed with the one flat lead upward on the monitor.
Right The power transistor is viewed with the one flat lead
rightward on the monitor.
Bottom The power transistor is viewed with the one flat lead
downward on the monitor.
Left The power transistor is viewed with the one flat lead leftward
on the monitor.
Terminat. Four-termination search
(X)
Components with four or more leads. There must be at least
two leads on either side. The numbers of leads are not
checked. It is viewed with the X-directional leads on the
monitor.
Four-termination search
(Y)
Components with four or more leads. There are at least two
leads on either side. The numbers of leads are not checked. It
is viewed with the Y-directional leads on the monitor.
