(1) Laser position measurement value
The descriptions required to measure laser height are displayed here.
Values set before measurement are displayed in parentheses.
① LA Pos (laser position)
You can change the laser height (position) as you like. The value
specified here is used as the current laser height when the system
starts judging if the laser height is within the appropriate range.
② "The height of component is measured at the same time."
When checked, the system measures the height of a component
before measuring the laser height. It automatically calculates the
laser height also at the same time. In this case, the laser height
automatically calculated is used as the current laser height when the
system judges if it is within the appropriate range. Therefore, you
cannot specify the laser height.
③ "The measurement result is reflected in the component data."
Check this check box if you want to store the measured laser height
into Component data immediately.
2) Range of laser position measurement
① Direction of movement
The system repetitively measures the laser height from the height
displayed in the "Laser position measurement value" column within
the range specified. When a component is centered with laser
successfully, the system finishes measuring the laser height.
Select one of the radio buttons below.

② Pick face of compo. → face under compo.
③ face under compo. → Pick face of compo.
The system measures the component height within the range
specified here in addition to a value displayed in the "Range of laser
position measurement". The start point can be on either the
picked-up side or bottom side of a component.
3) Screen displayed while the system is inspecting the laser height in Single
check mode
The following dialog box appears on the screen while the system is
inspecting the laser height in Single check mode. Data on a component
being inspected, pick-up position and laser height are displayed on this
dialog box to show the current inspection progress.

4) Result of inspection
The laser status value appears here if a component is centered with laser
successfully. The meaning of each item is the same as that for check
operation.

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.

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.
