(T) Direction of PCB transport
The PCB barcode readers are fixed to the top and bottom profiled rail using retainers. These can
be positioned as required on the profiled rails, and aligned with respect to the barcode labels. De-
pending on the position of the barcode strips, the barcode reader can be attached in a few simple
steps so that the strips can be read parallel to or across the PCB transport direction.

7.4.2 Description of the functions
7.4.2.1 PCB barcode reader for the single conveyor
The SIPLACE PCB barcode reader supports the flexible manufacture of SMD products, and in-
creases placement reliability. It recognizes all the code types conventionally used in industrial ap-
plications.
The laser scanner reads the barcode label on the topside or underside of each incoming PCB as
they are transported onto the input conveyor. The barcode data enables the line computer to au-
tomatically select the correct barcode allocation list from the previously created barcode assign-
ment list, and sends it to the station. If a barcode filter is defined, only information that is identified
as relevant within the barcode is compared. This procedure is carried out time neutrally during
placement of the PCB already in the machine. If several PCBs with the same barcode enter in
succession, the program is only transferred the first time. The following requirements apply to all
products to be produced using the PCB barcode:
– The component set-up must be identical on all the machines on the line
– All PCBs must be of the same width
7.4.2.2 PCB barcode reader for the dual conveyor
On the dual conveyor, the PCB barcode is only used to transfer the barcode via the GEM interface.
This is absolutely essential. The placement program cannot be supplied automatically.

transport direction, as close as possible to the sta-
tionary PCB transport side.

* This value can only be achieved if the barcode label on the PCB passes through the scanner
perpendicular to the machine’s transport direction.
** The position of the barcode reader on the input conveyor can be easily adjusted, depending
on where the barcode labels are located on the PCBs.
