<Wrong Polarity/Height Inspection Edit Tool>
If wrong polarity/height inspection is being selected, the comparison area (reference point:
yellow) and polarity mark area (measurement point: light blue) are displayed in the wrong
polarity/height inspection edit tool. You can edit a position and/or size of the comparison and/or
polarity mark area to perform wrong polarity/height inspection.
: Z scale is extended based on the maximum height value.
: The selected window is displayed.
<Target Component (Recommended)>
- Other Chip:
An LED level difference is detected and the polarity inspection is performed.
- SOP, QFP, SOJ, QFJ, SON, QFN, connector, other lead component, other non-lead component,
other bottom electrode component, CSP, BGA
An embossed mark is detected and the wrong polarity inspection is performed.
① Comparison area (reference point: yellow)
Specify a measurement range of height information used for the wrong polarity/height
inspection. Use the mouse to edit the window position and size.
In X-Y, X-Z, and Y-Z diagrams, reference point window position (yellow rectangle) and
measured value of the reference point height are indicated as dashed lines and upper and
lower limits of the inspection criteria as continuous line.
② Polarity mark area (measurement point: light blue)
Specify a measurement range of height information used for the wrong polarity/height
inspection. Use the mouse to edit the window position and size.
In X-Y, X-Z, and Y-Z diagrams, measurement point window position (light blue rectangle) is
indicated.
For details of the inspection criteria and process, see Inspection Logic Manual, "3.4 Wrong
Polarity/Height".

2.15.4 Optimizing Boolean Expressions and Inspection Criterion Values
Inspection criterion values are optimized based on the visual check result information
registered for each inspection window of model images. Optimization can reduce
missing/excessive detection of errors.
