STAGE 7 - VISION SYSTEM SETUP
Introduction The printer uses a vision system to carry out the following:
• Stencil/Board Alignment
• 2Di Inspection (optional)
• Board Identification - Selective Print/Pass Through (optional)
After the board is fed into the machine to the board stop position, the camera
moves into position to view the relative board and screen features. The infor-
mation from these camera images is used by the vision system to calculate the
screen correction needed and to identify the board, if selective print/pass through
is enabled. The camera and vision system is also used for 2Di inspection, if
enabled, for further information refer to the 2Di chapter in this manual.
Fiducials A fiducial is an alignment mark which is produced as a part of the artwork of the
board and the screen. There are normally several of these marks on each board,
some of which are used for board alignment and some for alignment when
placing components on the board. These marks, therefore, should be in the same
relative position on both board and screen. The vision system has a library of
synthetic fiducials of the most commonly found shapes. The dimensions of
these fiducials can be tailored by the operator to fit the fiducials on the board and
screen. After the vision system has been taught these fiducial parameters, it is
able to search the field of view of the camera and recognize any features which
resemble these fiducials. The centre of the fiducial is calculated and used as the
point of location.
The vision system conducts a search in the field of view of the camera looking
for any shape that resembles the programmed fiducial. After finding a shape it
is assigned a score comparing its shape and size to the shape and size of the
fiducial in the vision system memory. This score is set between 1 and 999, the
better the fit the higher the score.
NOTE
However, this does not mean that a fiducial score of 999 for example aligns more
accurately than a fiducials score of 700 for example.
This score is used, in conjunction with acceptance parameters set by the opera-
tor, to recognize the fiducial. The available fiducial shapes are:
• Circle
• Rectangle
• Diamond
• Triangle
• Double Square
• Cross
