17.3.3 PCB 3: Focus on Cluster Technique
PCB 3 consists of four clusters (pattern) each of which comprises three single circuits (board). The dimensions
and the placement configuration of the single circuits corresponds to those of PCB 2. Clusters 3 and 4 are ro-
tated by 180°. For each cluster a PCB position recognition operation is performed. Three fiducials are available
in each case. An ink spot is located on each single circuit.
