Preparing the ground for zero-defect production

Zero-defect production is a vital topic for many industrial companies. However, the route to this does not lead via the detection and elimination of defective parts, because beyond a certain requirement threshold quality is no longer selectable. On the contrary, the answer is to produce quality from the very beginning.

F & K Delvotec faces up to this challenge. F & K Delvotec bonders help you to take the decisive step towards zero-defect production with precise control factors and measurements at every stage of production. Test components which are specially developed and patented by F & K Delvotec perfect your end product down to the last detail.

High precision ultrasonic monitoring

F & K Delvotec optimises continuous quality testing with a range of highly efficient processes which inspect and test micro-electronic components during wire bonding. BPC (bond process control) optimises bonding results by tracking and regulating the ultrasonic energies which are optimal for various surface properties. The process patented for F & K Delvotec of continuously tracking transducer impedance during the bonding process supplement this procedure and makes it even more efficient.

In-head pull tester, in-line pull tester and PBI

Ultrasonic systems, test and measuring systems:

• The in-head pull tester ensures the non-destructive test of bonded thick aluminium wire.
• The in-line pull tester enables the extremely fast checking of components made of lightly threaded thick wire or lead frames without interrupting production.
• After bonding PBI (post bond inspection) enables precise checking of wire, bond height, positioning accuracy and further parameters.

• Highly sophisticated F & K Delvotec measuring and test equipment is available to make sure that all these ultrasonic systems can be perfectly installed in the F & K Delvotec bonders.
• This equipment is suitable both for service on the bond machinery and for quality assurance. It enables the continuous documentation of the condition and function of the ultrasonic systems and can, for the first time. also be used for the precautionary maintenance of these high-precision components.
