Barcode and Data Matrix Codes

Description and technical data

Description

The PCB camera can read

either a barcode or a data

matrix code. The data can be

used for traceability pur-

poses.

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.

Data Matrix Codes

Code types supported 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 multi-

ple data areas.

Minimum dot size 50 µ

Maximum size of data matrix

codes

≤ 30 mm and Y ≤ 30 mm, or

X ≤ 10 mm and Y ≤ 100 mm, or

≤ 100 mm and Y ≤ 10 mm

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.

(Station software version 707.1 SP2 or higher required)

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

Contrast Minimum 20 gray values.

Print growth The size of a module must be at least 1/3 of the cell size in the data

matrix grid.

The size of a module must be at most 5/3 of the cell size in the data

matrix grid.

Code types Code 39

Code 128

EAN-8 (AddOn 2, AddOn 5), EAN-13 (AddOn 2, AddOn 5)

Interleaved 2 of 5 (station software version 710.1 or higher required)

Minimum width of bar 50 µ

If the quality of the marking is high enough, the width can be reduced

down to 30 µ.

Maximum size of barcode X

≤ 30 mm and Y ≤ 30 mm, or

X ≤ 10 mm and Y ≤ 100 mm, or

X ≤ 100 mm and Y ≤ 10 mm

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

Uniformity of bars and spaces Each bar and space represents 1 to 4 bits (applies to all code types

implemented), whereby the number of bits corresponds to the width of

the bar/space. When the barcode is read with the PCB camera, it is

assumed that the code is flat. This is why the same nominal width is

applied to all bars and spaces in the symbol when reading 1D bar-

codes with the PCB camera. As a consequence, barcodes cannot be

read if a bar/space with n bits appears to be smaller than another bar/

space with n-1 bits.

Options

OSC package

The licensed OSC package

contains functions for simpli-

fied placement of odd

shaped components (OSC),

such as connectors or sock-

ets.

The license is activated via

SIPLACE Pro.

The following functions are

contained in the OSC pack-

age:

OSC measurement options

• Customized odd shaped

component

This enables the user to

describe any abstract pat-

tern on a component e.g.

connection leads of a tri-

angular shape. This pat-

tern can then be easily

created and edited at the

station, using the wizard

function.

• Stereo measurement

Stereo measurement

means that two images

are taken of each compo-

nent, from different direc-

tions, using a stationary

camera. These images

are overlapped to show

connectors, pins etc. in 3D

to support easy and pre-

cise evaluation of struc-

tures which, due to color,

shading or background

structures, are difficult to

recognize in conventional

2D measurement.

• Special position evalua-

tion

This function supports

separate definition of posi-

tion determining features

(x,y, angle) independent

of the features for good-

bad recognition. Place-

ment of snap-in compo-

nents

This function monitors

whether snap-in components

engage in the board prop-

erly, during automatic place-

ment.

Automatic calculation of

optimum acceleration

This function enables the

user to automatically calcu-

late the optimum accelera-

tion of individual axes for a

component at the station.

The acceleration values

found can then be checked in

an additional test run and

sent back to the program-

ming system if successful.
