Key Winning Features

High Integration Density

Interconnection technologies such as resistance and laser welding as well as micro soldering or ball-stud bonding (microflex interconnection) allow high integration densities.
Together with highly skilled manual cable manufacturing we can provide increased channel counts per cable compared to other manufacturers.

High Variability

CorTec’s interconnection technologies permit a combination of versatile electrode and substrate materials. Almost any electrode material can be interconnected — from a variety of flexible wires to rigid FR4 substrates for PCBs or even ceramics.

Reliable Process Portfolio

A wide range of processes are validated for the most common material combinations. Equally high  standards for customer individual solutions are guaranteed.

Reliability Testing

Continuous monitoring of processes and repeated testing allow the creation of cutting-edge interconnection solutions of highest reliability and stability in their biological environment.

Functionality Enhancement of Commercially Available Solutions

Commercially available connectors can be customized with interconnections such as our flat ribbon cables to create new solutions for previously unsolved implant wiring challenges.
