AI Technical Summary

Technical Problem

The issue with existing optoelectronic semiconductor components is that wire contacts protrude from the potting compound, leading to cosmetic defects, undesirable reflections, and risk of damage during soldering.

Method used

The solution involves embedding the connecting elements within a cladding, reducing their thickness and number to minimize protrusion, and using a flat molding process to encase the components, ensuring they do not extend beyond the front side of the semiconductor component.

Benefits of technology

This approach enhances optical properties by preventing defects and reflections, improving conversion efficiency, reducing component size, and protecting internal components from damage while maintaining current-carrying capacity.
