High Precision Beam Positioning –
Optional Pattern Recognition System
Applies the latest
video and software
technology for the
ultimate in beam
positioning accuracy,
repeatability, and
reliability.
Pattern Recognition – Template
Matching
Locates basic and irregular
patterns regardless of color,
lighting, or surface texture.
Identifies elements based on
the granularity of a part, the
part shape, or a combination
of both.
Defines multiple elements
within a template to eliminate
problem areas.
1. Train
2. Locate
3. Process
Pattern Recognition – Ease of Use
Graphical tools and stored templates
expedite setup time:
– Allows for easy system training to understand,
interpret, and characterize images found on any
particular part, circuit, or substrate.
– Sets of pattern templates may be created for
multiple devices, stored in a library, and easily
loaded into a production program when needed.
Pattern Recognition – Ensuring
Success
An estimated recognition success rate, based
on the uniqueness and specific parameters of
a target, may be obtained as part of the
system setup.
Synthetic targets can also be created when
actual parts are not available.
Characteristics of desired shapes can be
drawn from the library to create an ideal part.
New Larger Work Area
Larger work area allows
for parts up to 10”Y x
12”X
