As the dimensions of components become smaller and smaller in size, the lead interconnection and insertion
densities increase, and board structures become more complex, the quality demands on the placement accu-
racy of the machines continue to rise. In order that these requirements be satisfied the SIPLACE 80 S-20/
F

placement machines are equipped with optical recognition systems (so-called
vision systems
) not only for
centering the printed circuit boards (
PCB vision system
) but also for centering the components (
component
vision system
).
5.1.1 Vision Systems in the SIPLACE 80S-20 Placement Machine
On the SIPLACE 80S-20 automatic placement machine, with its double gantry system and two 12x revolver
placement heads, each placement head is equipped with a CCD camera system for component position rec-
ognition. In addition a CCD camera system for PCB position recognition is mounted on each gantry underside
(5 - 5 and Fig. 5.1.3, Page 5 - 6).

The range of components which can be handled by optical centering and placement ranges from 0402 to
SO28 components, or, to put it another way, component sizes varying between 1.0 mm x 0.5 mm up to a max-
imum of 18.7 mm x 18.7 mm with component thicknesses from 0.3 mm to 8.25 mm.
The PCB vision system of the 80S-20, 80F

and 80F
5
machines centers boards with dimensions ranging from
a minimum of 50 mm x 50 mm up to 460 mm x 460 mm (standard), with an optional maximum of 508 mm x
460 mm. The board thickness may vary within the range of 0.5 mm and 4.5 mm.

The control unit of the machine accommodates an evaluation unit (ICOS MVS system) (5 - 7) which pro-
cesses and quantifies the signals from the camera systems (PCB and component vision systems) of each
placement head. The deviations from the nominal values are used for determining correction values which are
then used in the recalculation of the placement positions and the skew of the components to be inserted.
