Vision system verifies board
output at full speed
HawkEye is a new automatic print verification technology that operates at the line beat rate
HawkEye assesses 100% of printed boards and gives a rapid go/no-go indication for each. Faulty boards can now be automatically isolated in real time. Explaining that many manufacturers still rely on error-prone manual inspection to identify unacceptable boards, Martin Symons Manager of DEK's Vision Engineering Team introduced HawkEye.

For production of today's electronics products, process speed is the name of the game and, until now, keeping up with the line beat rate meant sacrificing thorough inspection

"From an original concept developed by our Vision Technical Specialist David Gaukroger which broke down the inspection proposition to the few bare facts that define whether a board is fit to be passed on to the next process.
As a result, HawkEye was developed by our dedicated expert team of vision engineers and provides a simple go/no-go indication just like a human operator.
But HawkEye is more repeatable, and verifies 100% of boards at line beat rate".

The new system is intended to complement DEK 2Di, a two-dimensional inspection system that provides a quantitative assessment of print quality and also inspects the stencil.
Indeed, Hawkeye can be used alongside a 2Di system installed on a single machine.
But the HawkEye verification routine rapidly scans the board as a series of stripes, and collects a tightly defined set of monochrome image data.
Comparing these results with user-defined limits of acceptability, HawkEye quickly indicates whether the board is fit to pass through to component placement or other downstream processing.
The user can also program HawkEye to inspect only certain areas of the board, for example where print deposit density may be particularly high.
This allows the user to adjust the total verification cycle time if necessary, and to derive maximum value from the system within the line beat rate.
The new HawkEye print verification system will be available as an option on all new DEK automatic machines, and as a machine performance upgrade (MPU) for existing platforms in the field, subject to specification.
