5.4 PCB barcode
5.4.1 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 machine controller for fur-
ther processing.
Fig. 5.4 - 1 PCB barcode block diagram
The PCB barcode readers are installed on the input side of the placement machine, above and
below the PCB conveyor, so that barcode labels on the topside and underside of the PCBs can
be read.
A maximum of four PCB barcode readers may be retrofitted in order to read the topside and un-
derside of the PCB on the transport track.

(2) Profiled rail for ‘underside’ PCB barcode reader
(3) Profiled rail for ‘topside’ PCB barcode reader
(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.
