Fibre Coupling

Aifotec assembles fibres or optical cables with active coupling to your chip

Aifotec is a recognised specialist in integrated circuit packaging for photonic and semi-conductor components. Our speciality is high-precision, fully automatic assembly.

Aifotec supports all leading process equipment such as glass, ceramic, polymer and silicon with laser spot size die bonding. We also support advanced oven-based epoxy bonding technologies.

Laser-Based Spot Size Eutectic Bonding

Aifotec’s laser-based spot size bonding provides precise passive assembly of up to ± 0.5 μm @ 3 sigma. The advantage of our technology is as follows: The local heat penetration through the laser system guarantees a very fast eutectic bonding process with little oxide formation and low heat impact on neighbouring fields
