Opto, HF

Long low loop consistence

With glued LEDs the frequency is particularly critical so as to avoid resonance in the small components.


High current.

Pins & transducer expertise

Ribbons require more bonding energy than wire bonds than can lead to oscillation challenges. F&K transducer expertise come from over 40 years of in house transducer manufacture.

Power electronics

Energy density

Ribbons are used in higher current devices.

Multiple dense loops

The pattern recognition allows for incredibly fight spacing of Alu ribbons. Here cutter & tool are customised to achieve the tight spacing.

Short ribbon loops

Keeping thermal loading as homogeneous as possible Our ribbon process enables the shortest loops and maximum bonded surface.
