7.7 PCB Alignment
[00119677-xx] PCB alignment for single conveyor, SIPLACE HF/X/CA/D3
[00119678-xx] PCB alignment for dual conveyor, SIPLACE HF/X/CA/D3
7.7.1 General
PCBs to be processed sometimes have a length to width ratio of 1:2 or worse. This means that
the shorter side of the PCB points in the direction of travel. During travel, such PCBs may twist
slightly and, as a result, the fiducials no longer lie within the PCB vision camera's search window.
In this case, the "PCB alignment" option ensures that these PCBs are realigned precisely at the
stopping position.
If boards with recesses are processed in the direction of transport, this can lead to different pro-
cessing positions between machines with mechanical stoppers (HS-50, S-25 HM, F5 HM) and
machines which monitor this position with a laser light barrier (X, CA, HF series, HS-60, S-27 HM).
The "PCB alignment" option ensures that the PCBs are stopped at the same position on all PCB
conveyors. The "PCB alignment" option is available for both single and dual conveyors.

7.7.2 Functional Description
The PCB is transported into the placement area until the laser light barrier triggers the stop signal
for the PCB conveyor. The lifting table with the PCB stops then moves up into a position in which
the PCB is not yet clamped and can still be moved by the conveyor belts. The two PCB stops are
level with the PCB, and the PCB supports (magnetic pins) are already in contact with the PCB.
The two conveyor belts move the PCB against the PCB stops and align them at the same time.
The lifting table then moves into its top end position, clamps the PCB and releases it from the PCB
stops so as not to affect the placement process. After the placement process, the lifting table and
PCB alignment are lowered and the PCB is moved on.

7.8 Siemens Interface
[00116808-xx]SIPLACE interface HF/X/CA/D3
The conveyor interface for CA series machines is configured according to the SMEMA standard.
However, you can also use the interface according to the Siemens standard. This is of benefit, if
a CA series machine is to be integrated into older SIPLACE lines, in which case it would not be
necessary to retrofit the older machines to conform to the SMEMA standard.
Simply configure the conveyor interface for the CA series machines to the Siemens standard and
connect the machine to the corresponding interface cable.
For more information, refer to the "Retrofitting Guide for Siemens Conveyor Interfaces"
[00194343-01].

The retrofit kit consists of the following modules:
– Mechanics, comp.: stopper, sensors, cable and assembly parts
– Optional CD for enabling the function on the SIPLACE Pro computer
– Retrofit instructions
NOTE 7
The Long board option must be ordered 2x for the dual conveyor.
