6.1 Row and Column Definition
VIH checks the board structure by analyzing the origins of each panel. Panels with the same x
offset belong to the same column; panels of the same y offset belong to the same row:
Figure 6-3: Row and column definition
VIH considers panels to be in the same row/column if their ink spots have the same x or y
coordinate. Same means that the value is inside a range of 2 mm:

6.2 XML Format
The file name consists of the barcode name of the individual board and the file suffix (xml or txt),
e.g. 12345.xml. The file is an xml file with UTF-8 encoding. This format (also known as "iSkip") can
be read by the station directly.
Example
<?xml version="1.0" encoding="UTF-8"?>

Data Validation
The NO_ROWS and NO_COLUMNS values are used to validate the data. The number of rows and
columns detected by the VIH option are compared with the numbers of rows and columns seen by
the external system.
NO_SINGLE_CIRCUITS = NO_ROWS * NO_COLUMNS
