Bond Wire Break Detection with a Fiber Optic Pair
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 DF-G2 series has a has up to a 10 microsecond response time, allowing it to respond to wire breaks quickly and efficiently.
