Ultra-long Flexible Printed Circuit Boards for Twist Capsules, Magnetic Field Manipulators and Rotor Blade and Wing Sensors

After intensive development work, ANDUS has designed a manufacturing technology that allows process-reliable production of flex multilayers with up to 4 layers and up to 5 m length without folds
or splitting up.

The advantages of such long-flex boards e.g. as substitutes for long cable harnesses or to solve complex measuring tasks are apparent:

Electrical connector and the functions of a circuit board in one

Maximum flexibility for the assembly in confined installation situations

    -  Ultra-flat
     Individual adjustment of conductor geometry and outline
    -  Defined rigidity for defined installation situations
     Low weight

High speed signal transmission with controlled impedance

Maximum reliability through

     Polarity and bonding safety
    -  Economisation of plug-in connectors and cable links
    -  Constant temperature of 150°C

Twist Capsules

In cooperation with a renowned industrial partner, a 5-meter flexible printed circuit board was developed and produced for satellite communications, which is being utilized in a new European telecommunications satellite program.

The highlight of the ANDUS flexible technology is not only its maximal length of up to 5 meters, but also its structural make-up, consisting of up to four layers to provide for higher rates of data exchange.

In the concrete application the flexible printed circuit board is used as a supply and data connector between the main and laser module. The minimal amount of torque exerted upon the laser module by the circuit board and the ability to transport higher volumes of data via impedance-controlled conductors over four levels make it an absolute novelty in the market.

In contrast to conventional cable solutions, ANDUS technology provides decisive advantages. The Twist Capsule not only can increase the signal density, but also reduce the weight with a minimum of space. The high level of flexibility and the reproducible tensile behavior guarantee the extreme durability and system reliability required.

This technology is suitable for all applications in which the position of the axes (angle, elevation or yaw) can generally be ascertained at less than 360° with a twist capsule.  This presents completely new solutions, for instance, in electric optical sensor systems (E-O systems) with complex high speed data or signal transmission.
