7.4.3 Type of illumination
The following types of illumination can be selected on the multicolor PCB camera:
– White lighting
This type of illumination is used for standard PCBs with tinned fiducials.
– Blue oblique lighting
In most cases, this can be used to greatly improve the contrast with bright fiducials on a light
base material, such as ceramic or CEM. Fiducials covered with solder resist can also be de-
tected better on a light background.
– Infrared lighting
This type of illumination is particularly useful for fiducials that are covered with solder resist
or for fiducials on flex materials. It is also sometimes possible to improve detection of silver/
platinum fiducials on ceramic. This should be tested by carrying out a test centering or place-
ment run.
7.4.4 Fiducial and ink spot criteria
The fiducials and ink spot criteria are described in sections 3.11.5.3 and 3.11.5.4, page 162.

7.5.1 Overview
The PCB barcode scanner is used to automatically record and decode barcodes on PCBs. The
PCB barcode scanner 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 scanners 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 scanners 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 scanner:
– 1D barcode scanner
This barcode scanner processes barcodes. 7
– 2D barcode scanner
