5.2 General Notes About the Barcode
In this day and age, increasing numbers of components, individual components, semi-finished and
end products are being uniquely identified with a barcode, which makes them easier to check. This,
in turn, makes it easier to control production, stock-keep and to trace components in the event of
errors. Both one-dimensional (1D, e.g. barcodes) and two-dimensional (2D, e.g. data matrix codes)
codes can be used.
NOTICE
Barcode changeover
Before you use a new barcode, we recommend that you contact your SIPLACE Service
team and have the barcode tested in advance.
5.2.1 Structure of 2D Barcodes
Barcode types:
1. "Stacked" codes, these are essentially one-dimensional barcodes that are printed directly over
one another. Typical stacked barcodes include the PDF 417, RSS-14 Stacked and the 16K
code.
Fig.81: Stacked barcodes
2. 2D barcodes, known as "matrix codes" are another variant of the 2D barcodes. Again there
are various types commonly used, such as Aztec code, Maxi code, Code One and the data
matrix code.

Data matrix code:
The data matrix code consists of 4 main components.
