Ultrasonic ball wedge Au

20µm fine wire for 45µm deformed balls (Free Air Balls = >35µm) placement at fine pitch 60µm.

Gold flashed surfaces are often not so consistent. The security ball bonds ensure durability.

Specialized loop forming capabilities allow long and low loop shapes.

Through our calibration routine, we can achieve accuracies down to +/- 5µm.

Placement precision, motion stability, loop control. F&K automated ball wedge since 1977.

HF loop consistency through perfected looping wire drag consistency.

“stich-on-ball” tailless bumping & placement accuracy allows for chip to chip connections.

Our Stitch on Ball process give the ideal surface for the destination bond.

Motion stability & constant drag for a comprehensive loop library.

A ball-wedge flame off typically takes about 6 ms. The nEFO logger tracks the current and resistance of every flame off with millisecond resolution.

Easy diagnostics for an imperfect world. The nEFO monitoring can raise an alarm and makes diagnosis the millisecond event straightforward.
