8.1 PCB Fiducials
Digital PCB-camera with Multicolor-illumination.
8.1.1 General
l
This digital version of the PCB-'Multicolor'-camera SST 24 is different to the SST type 18 - the an-
alogue 'Multicolor'-PCB-camera -.
8.1.2 Kind of illumination for fiducials
As a recommendation on kind of illuminations in respect on the PCB material:
Parameter PCB-camera
For Machine X2 ; X3; X4
SST 24
Resolution 11,7 µm/pixel
Field of view 5,7 x 5,7 mm (695x494 Pixel / used: 494x494 Pixel)
min. fiducial size Cycle, square, rectangle 0,25 x 0,25 mm / and their rings 0.3x0.3 mm /cross 0,3 x 0.3
mm / double cross, diamond (is a 45° square) 0,5 x 0,5mm (make at diamond
0.25mm edge length or 0,35 mm height/width). min. Stroke thickness each structure
fiducial 0,1mm.
max. fiducial size 3 x 3 mm
Kind of illumina-
tion / -colors
Blue
IR diffuse (flat)
IR steep
White diffuse (flat)
White steep
Kind of illumination /
color
PCB-Material Example
Blue to recognize gold- or silver colored fidu-
cials on white (ceramic) material
e.g. Gold on ceramic
IR diffuse To recognize (solder resist) dull paint lay-
ered fiducials (also Glass plates)
IR go through solder resist and illumi-
nate covered fiducials.
IR-steep is always
combined with diffuse
To recognize shiny paint layered fidu-
cials
White diffuse To recognize dull fiducials on any other
PCB material and surface
Hot leveling fiducials
White steep is always
combined with diffuse
To recognize shiny fiducial surfaces

Teaching fiducials (and bad mark) a complete programmed PCB is scheduled to the station - in-
clusive all fiducial coordinates -! With teach function is the 1st PCB moved in placement area for
teaching fiducials and bad marks. Teach all individual fiducials and with 'Test all fiducials' test them
on all camera's of the station. Then with the next board start production.
8.1.2.1 Fiducial arrangement on the PCB
If the position recognition fiducials on a board arranged in a row the PCB-position PCB-angle and
the length yield could be determined. Therefore 2 fid. are enough so SIPLACE Pro transmits only
2 fiducial positions.
8.1.3 Import fiducials
All fiducials, for ICOS have to be re-taught for SIPLACE Vision.
There is no mutual influence of the two vision systems because the Fiducial teach data are sensor
specific saved!! (5 SST, 24 SST, ..).
Specialties: The SIPLACE Vision accept dual cross as a kind of synthetic fiducial; ICOS-Systems
define this kind of fiducial as a ‚2D-pattern' a Import of this kind of fiducial is excluded.
Please Note:
Fiducials for SIPLACE Vision have to be teached new!
To the Station transferred PCB-
recognition fiducial positions.
Here is calculated the: PCB-
position; PCB-angle; and PCB
length and width yield.
