ELECTRODES

With a thin film metallised electrode coating from Polyteknik, the electrodes will have a consistent and reliable electrical connection. Metals are the most common material for electrical conductor films and can be used as blanket metallization or perhaps formed into stripes. Conductor lines are known for being used in hybrid microcircuit technology and in the manufacture of semiconductor devices. The electrical conductors are usually multilayer films where each layer has different functions and characteristics.
Polyteknik can offer a DC/RF sputtering of noble metal and alloys, such as silver, gold, titanium, nickel, copper and other materials as well as combinations of materials to achieve the desired result. We offer both electrodes on ceramics and polymers.

ELECTRODES ON CERAMICS

Our coatings for piezo electrodes have shown outstanding conductive characteristics and high performance in heat and corrosion resistance. Typical piezo electrode patterns are, for example: solid patterns, wrap-around patterns, side tab patterns, insulation band patterns, as well as customised patterns.

Polyteknik offers a great variety of electrode patterns for your piezo components. Besides the standard silver and gold coating for piezo electrodes, we can do high quality stabilized electrodes by using materials, such as nickel and titanium. The high quality electrode materials are widely used for applications within medico, industry, defense and aerospace.

Piezo2479

The standard Piezo2479 coating is a chrome and gold combination, which has shown outstanding performances in resistance against corrosion and heat. The thickness of the thin film coated electrode can be in the range of some hundred nanometers and up to 2-3 µm.

Piezo0047

The standard Piezo0047 coating is a silver electrode, which has a consistent and reliable electrical connection. The thickness of the thin film coated electrode can be in the range of some hundred nanometers and up to 2-3 µm.

Cerammet

Due to the substrate material and the environment the electrode is being used in, there can be a need to look into different coating materials. With a nickel or titanium electrode, it is possible to attain an incredibly stable performance than with a standard silver electrode.
