3.12.3 Description of the functions
For placement, the PCB is clamped from below. The distance between the top of the PCB and the
placement head thus remains unchanged for each PCB, and is not dependent on the thickness of
the PCB. The placement rate is thus independent of the PCB thickness. The PCB fiducial center-
ing can also be optimized. Since the distance between the PCB surface and the PCB camera re-
mains the same, the PCB camera is always focussed on the PCB surface with the same
sharpness. The PCB fiducial contours are optimally mapped on the CCD chip of the PCB camera.
The width of the circuit board conveyor is set and monitored by an integral control circuit. It can
be selected by calling up the program. The control circuit then actuates the stepping motors until
the desired width is reached. The width adjustment is therefore independent of other machine
components.

The transport height can be modified on the machine, thus allowing it to be integrated into lines
with a transport height of 830, 900, 930 or 950 mm.
The PCB conveyors communicate with the individual machines via the SMEMA interface or the
optional SIEMENS interface.
The fixed transport side can be located on the left or right for both the dual conveyor and the single
conveyor. With this conveyor, the fixed side can be easily switched from right to left and vice versa
using the station software.
The circuit board conveyor is monitored and controlled with optical sensors. If the board has
reached placement area and passed the light barrier, it is braked. A laser light barrier determines
the position of the board. As soon as the circuit board has reached its target position, the conveyor
belt is stopped and the board is clamped from below.
