7.5 PCB barcode reader
7.5.1 Overview
The PCB barcode reader is used to automatically record and decode barcodes on PCBs. The
PCB barcode reader sends the read data via its serial interface to the transport controller and then
for further processing to the machine controller via the CAN bus.

The PCB barcode readers are installed on the input side of the placement machine on the PCB
conveyor. Up to four devices can be retrofitted to each machine. The barcode readers are fitted
so that the barcode labels on the topside and underside of the PCBs can be scanned on both
tracks of the dual conveyor.
There are two variants of the barcode reader:
– 1D barcode reader
This barcode reader processes barcodes. 7
– 2D barcode reader
This barcode reader processes matrix code. Matrix code is primarily used when there is
not enough space for barcode labels. The 2D barcode reader also reads conventional bar-
codes. 7

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.
7.5.2 Description of the functions
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 SIPLACE Pro computer uses the barcode in-
formation to automatically select the right placement program from the previously created barcode
assignment list (BA 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 bar-
code 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
