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