Barcode types

Technical data

The PCB camera can read a

Data matrix code, a 1D bar-

code or a QR code. The

data can be used for trace-

ability purposes.

The barcode can be on the

board itself or on a compo-

nent. In addition, it is also

possible to attach a barcode

label to a board or a compo-

nent and to then read this

barcode label with the PCB

camera, directly after place-

ment. The focal height must

be taken into account during

reading, if there is a barcode

or barcode label on the top of

a component.

General information for all barcode types

Data matrix codes

Ambiguity No read errors are issued if multiple valid barcode symbols are found in a

particular region of interest (ROI). In this case, there is no clear rule, defin-

ing which of these valid barcode symbols would be read.

Ambiguity can be avoided by:

• Using a suitable ROI size

ASCII null characters Barcode information should not contain any ASCII null characters (ASCII

NULL), as the 0 byte in the software is interpreted as an final (end) char-

acter.

Code type Only data matrix ECC 200 is supported.

No. rows/columns All combinations of rows/columns as defined in the standard will be

accepted, including rectangular symbols and large symbols with multiple

data areas.

Minimum dot size 5 pixels

Symbol angle All symbol angles will be accepted.

Inverse symbols Inverse symbols (light modules on a dark background) will be accepted.

Mirrored symbols Mirrored symbols will be accepted.

Ratio of column width to row

height

1/2

≤ (column width) / (row height) ≤ 2

Region of Interest (ROI) The area in which the barcode is searched for (ROI) should not exceed the

following values:

Width of ROI

≤ 6 * width of barcode symbol

Height of ROI ≤ 6 * Height of barcode symbol

Minimum width of bar 5 pixels

If the quality of the mark is sufficient, the width can be reduced down to 3

pixels.

Minimum height of symbol 5% of length of whole symbol.

Symbol angle All symbol angles will be accepted.

Inverse symbols Light bars on a dark background will be accepted.

(Station software version 708.0 or higher required)

Mirrored symbols Mirrored symbols will be accepted.

(this corresponds to a rotation of 180 degrees for 1D codes)

Region of Interest (ROI) The area on the board, in which the barcode is searched for (ROI), should

not exceed the following values:

ROI (direction of reading)

≤ 3 * symbol width

ROI (vertical to direction of reading) ≤ 10 * symbol width

Code type QR code in accordance with ISO/IEC 18004 model 2.

Station software version 711.0 or higher required

No. rows/columns All versions still defined in the standard (i.e. number of rows/columns) are

accepted.

Minimum dot size 5 pixels

Symbol angle All symbol angles will be accepted.

Inverse symbols Inverse symbols (light modules on a dark background) will be accepted.

Mirrored symbols Mirrored symbols will be accepted.

Height of ROI ≤ 6 * Height of barcode symbol

Virtual Inkspot Handler (VIH)

The virtual inkspot handler

(VIH) allows you to scan in

inkspots from an external

system.

This option can be used for

external systems to define

which panels are to be

produced and which to be

omitted. A panel is a specific

part of a printed circuit

board. This concept is much

more flexible than the

physical inkspot concept.

It can be integrated into the

ongoing production process,

if external systems

individually decide whether

each panel it is in a good or

bad state and whether

additional processing steps

are to be omitted or not.

The boards are typically

measured by the external

system and the information

about which panels are good

or bad is then available.

The use of this information

via VIH offers the benefit that

no physical inkspots need to

be read by the PCB camera.

This improves performance,

particularly for boards with a

large number of panels.

This option can also be used

if the panels do not have

room for a physical inkspot.

Process Data Interfaces (PDI)

The process data interface (PDI), which can be addressed via

the OIB interface, enables you to access not only the trace-

ability data of the components placed but also various process

parameters for the component placement. The PDI makes

over 40 process attributes per placement position available,

such as:

• Pickup (actual pick position, pickup location ID)

• Dipping (result, timestamp)

• Vision measuring (result plus camera ID)

• Placement (actual place position, ref. desig., vacuum val-

ues)

The data packages contain the data for each board and stop-

per position.

Each individual data package contains a maximum of 200

placement positions.
