3.12 PCB single conveyor
The placement machine is supplied with a single PCB conveyor as standard. The dual PCB con-
veyor is available as an option from the factory (see Section 3.13
, page 153). The left or the right
side of the PCB conveyor can be used as the stationary side, as required. 3
The conveyor belts are driven by DC motors. There is a lifting table for clamping the PCBs in
each processing area. The PCB conveyor width can either be set from the user interface or pre-
set in the placement program. 3

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 no longer dependent on the
thickness of the PCB. The placement rate is thus also independent of the PCB thickness. The
PCB fiducial centering can also be optimized. Since the distance between the PCB surface and
the PCB camera remains 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. 3
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. 3
