6.7.3 SOT Direction Check
6.7.3.1 Overview
The machine uses the OCC to check the 3-termianl SOT direction.
6.7.3.2 Checking function
The function of this 3-terminal SOT direction check is overviewed in Table 6.7.3.2.1.

Check Description Check mode Remarks
3-terminal SOT
direction check
Checks to see if the direction
of a 3-terminal SOT
component is correct.

Continuous inspection
6.7.3.3 Operations
① Head used to pick up a component
The system automatically selects a head that is used to pick up a component.
The system selects and uses a nozzle already attached on a head rather than
one not attached so that the frequency of nozzle replacement can be reduced.
However, the system may use a different head every time it measures a
component depending on the nozzle attachment condition.
② Applicable component size
The applicable SOT component size is 1608 to 4.0 mm x 4.0 mm. The width
and length of an electrode is 0.2 mm to 1.0 mm and 0.1 mm to 1.0 mm
respectively.
③ Returning a component after checking it
The system returns some checked components onto their original positions, or
discards other ones depending on their packaging style as shown in Table
below. The “Question” dialog box appears on the screen to prompt you to
select whether to discard a checked component. Where to discard a
component is determined according to the setting of “Compo Reject to” on the
Component data screen. When checking continuously, the system displays
the selection dialog box that asks you if it discards all components before start
of check, or displays the “Question” dialog box every time it checks a
component.

to” is set to “Trash conveyor” or “Protect”.
③
Selecting a feeder used to pick a component
If two or more feeders are assigned to the same type of components on the
Pick data screen, the system starts picking up components from one whose
data was entered first of all by default. Only in Independent Inspection mode,
you can change the feeder used to pick up a component intentionally.
④
Changing the coordinates of a component pick-up position
When a component is not picked up properly, manually enter the coordinates or
use the HOD device to teach them to change the coordinates of a component
pick-up position.
⑤
Manual component pick-up
If there is no Pick data created, you can manually attach a component to a
nozzle. However, in such a case, you cannot enter coordinates that indicate
the component pick-up position. You cannot operate a feeder either.
⑥
Check
The system places a picked-up component onto the SOT direction check stage
at a 0-degree angle, and uses the left OCC to judge if this angle is appropriate
or not.
