6.1.1 Restrictions
The following restrictions apply for the descriptions in the inkspot file:
– Only a panel matrix with rotations of 0° is supported.
– Gaps between the panels are allowed but have to be regular.
Examples
The following descriptions are allowed:

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

6.3 Wafer Map Format
In the VIH interface via the BoardGateKeeper, panel names must be supplied. However, in the
inkspot files on disk there are no panel names but row and column information instead. The rows
and columns have to be mapped to a panel name.
6.3.1 Mapping Rows and Columns to a Panel Name
For this, the following two algorithms are implemented in the SIPLACE VIH XML Wrapper:
Naming Convention
Rows and columns are mapped based on a naming convention. By default the names of the panels
are PanelName_Row_Column (e.g. something_5_7).
Restrictions:
– Only rectangular boards are supported. These are boards having the same number of columns
on each row.
– There is no check whether the naming is correct or not. E.g., there is no check whether the
rows and columns are switched.
Geometric
Rows and columns are mapped according to their geometric location on the board.
Restrictions:
– Only rectangular boards are supported. These are boards having the same number of columns
on each row.
– In each panel matrix, the position of the original panel must be 1,1:
