This makes it possible to obtain the results that are not offset.
2.2.1 Mini-mold transistor / SOTs Special –(1)
Though the “Special” mode is provided for recognizing the trimmer capacitors, variable
resistors and other components, the “Power Transistor” mode (See “2.3. P-Tr” ) or the
“Special Quad.” mode (See “2.12.4. Special Quad”) are recommendable to be used for these
components. (*Please note that the operation is not covered under YAHAMA guaranty.)

Check Upside-Down (Dispersion)
The top surface and the bottom surface of the components is identified by checking the
variation of the brightness (dispersion) of the determination range.
It is applicable for the components with the characters printed on the molded area of the
pickup surface.
Option 1
Threshold of 3-sigma
Sets the threshold of the value of the brightness variation (3sigma) in the
determination range.
The value becomes larger as the brightness variation becomes large.
Option 2
Threshold of Average
Sets the lower limit of the average brightness (Ave) in the determination area.
It is available only when “Dispersion” is specified as “NG condition”.
It is used when over-determination occurs due to the variant set for
determination.
Option 3
Judgement Flag (Some old version software may not be equipped with this
function.)
Table 16
Specify the determination range in the Lead Group 1 in W direction.
(If it is necessary to offset to the E direction, set to East.)

- Dispersion: When the variance of the brightness in the
determination range is larger than threshold, it is determined
to be an error.
- Non Dispersion: When the variance of the brightness in the
determination range is smaller than threshold, it is
determined to be an error.
