Bond Wire Break Detection with a Fiber Optic Pair

Detecting wire breakage quickly can prevent unnecessary downtime and errors. In order to accurately detect when a wire breaks, a sensor is needed to monitor the space below the wire.


A pair of fiber optics in opposed mode are located below the bond wire. When the wire breaks and falls through the beam, an adjustable one-shot output pulse is energized.

This application does not require a consistent positioning of the bonding wire.

The dual fiber D10 series has a unique, ac-coupled amplifier that senses tiny signal changes when the target moves through the beam.
