7.2.1 Description of the functions
The flip-chip vision module increases the capability for processing fine-pitch and flip-chip compo-
nents with extremely fine lead pitches. This add-on module for the fine-pitch vision module
increases the resolution many times. The lighting layout is fundamentally different. At optimal illu-
mination, the images of bumps are as large as possible, and disruptive orthogonal structures (as
can occur on chip printed conductor tracks, for example) are suppressed. With less pronounced
disruptive structures, enhanced illumination intensity can be achieved by combining lighting fix-
tures resulting in high recognition reliability, even with the generally square connection surfaces
of ‘bumped’ flip-chips as used in conductive adhesive technology. Special search algorithms are
used to recognize the bumps in environments subject to disruption.
7.2.2 Safety instructions for the component vision modules on the CF machine
DANGER
NEVER modify or bypass safety devices on the CF machine, or on the fine-pitch or flip-chip mod-
ule. 7
The optical radiation from the fine-pitch or flip-chip vision module conforms to laser class 1,
provided that the module is permanently installed in the placement machine, and the protective
hoods are closed
(EN 60825-1 or IEC 825).
