Component alignment is used for the alignment of components on leads, edges or
bumps, prior to placement on the board. Depending on the configuration of the
machine there are four alignment options available.
The component laser module is part of the Placement Head Laser Vision. The
component laser module is used for component presence check, component
alignment, toolbit type identification and toolbit verification.

The Component Vision (CV) system is used for the alignment of components on
leads, edges or bumps. Component Alignment is achieved by moving the
component above the lens of an upward-facing digital camera. A combination of
multiple light sources (dark- ,mid-, and bright field illumination and for LFOV also
back light illumination) ensure sufficient contrast between the component (leads)
and the background. Utilizing these light sources the A-Series are capable of
aligning a large range of components. The illumination intensity is automatically
chosen based upon the reflectivity of the respective components. The CV camera
determines the position of the component with respect to a reference plate. The
deviations, together with the fiducial alignment values, will be used to determine the
correct placement position.
There are three component vision modules available for the A-Series.
The Component Vision Camera holds one upward looking camera and can inspect
a single component up to 45 x 45mm in one view. Components with bumps down
to 300 micron with a 500 micron pitch can be measured.

LFOV is holding two upward looking cameras. It is used to align and inspect a wide
range of components up to 45 x 45 mm or 66 x 23 mm with bump or lead width
down to 150 micron. The maximum component size for components picked with
the Placement Head Dual Vision is 21 x 21 mm as four components can be
inspected at the same time. Components up to 165 x 45mm can be measured with
restrictions.
LFOV
SFOV is also holding two upward looking cameras and is used for ultra fine pitch
components like CSPs and flip chips. By use of a smaller field of view (22x22mm)
a higher accuracy can be achieved. The SFOV can be used with the Placement
Head High Accuracy and can align two components at the same time.

: Components larger than the noted size can be processed. The CV LFOV can measure
a 165mm long connector, however some restrictions may apply. Also components of
66x23mm (or 23x66mm) can be measured in one view using the Placement Head
High Accuracy.

Each placement robot requires a toolbit exchange unit to exchange toolbits
automatically. In less than one second a toolbit is exchanged, while production
continues. Holding multiple positions a maximum flexibility for component range
and family setup is ensured

The A-Series is operated via a touch screen and a full graphical user interface. The
user interface complies to SEMI E95 to maximize ergonomics, ease of use and
minimize learning time. The interface can be set to different language modes. This
can be done while the production is running and is therefore, suited to multi-lingual
environments.
A wide range of languages is standard available, please check with the local
Assembléon representative for more details. All other languages can be made
available upon request.
Chinese Graphical User Interface
Board Identification (BI) can be used to provide barcode -ID and traceability
information. It features:
A check of the board ID versus the running placement program. On error the
system will block the board from entering the machine.
Board identification for traceability (see paragraph on traceability).
