17.2.3 PCB 3: Focus on Cluster Technique
PCB 3 consists of four clusters each of which comprises three single circuits. The dimensions and the place-
ment configuration of the single circuits corresponds to those of PCB 2. Clusters 3 and 4 are rotated 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.
