What are Thick Film Gold Conductors?

Thick film gold conductors are printable conductive pastes used in the manufacture of hybrid microelectronic circuits and devices.

Formulated with gold as the primary conductive material, these pastes are screen printed onto ceramic substrates such as alumina and aluminium nitride, then fired to form highly conductive, durable metal tracks and features.

Thick film gold conductors are widely used where high electrical conductivity, reliable wire bonding, and long‑term stability are required.

Key Features of Gold Conductive Pastes

Suitable for all processes – etchable, solderable, etc.
Gold and aluminium wire bondable
Wide range of firing temperatures (500 – 1,050ºC)
Thinners available for extended working life (information on-demand)

About Koartan Gold and Silver Pastes

Their Gold pastes are suitable for high conductivity thick film requirements, on both alumina and aluminium nitride. Included in the portfolio are both wire-bondable and solderable materials, as well as pastes for via plugging or edge coating. Wire-bondable and solderable Gold pastes are also available for low temperature firing applications, starting at 500°C, without any compromise in adhesion. Lead-free and cadmium-free options are also available.

The range of Silver-bearing pastes includes conductor materials, termination metallisation’s, plateable inks, low-temperature firing from 400°C, and also lead- & cadmium-free materials.

Koartan also offers combinations of Silver Palladium and Silver Platinum with a wide range of properties: high leach resistance, excellent solder acceptance, and some lead-free and cadmium-free products.

Key Characteristics of Thick Film Gold Conductors

Thick film gold conductors offer reliable electrical conductivity after firing, with stable long‑term performance. Gold’s resistance to oxidation and corrosion makes them suitable for demanding and long‑life applications.
Thick film gold conductors are compatible with wire bonding, particularly gold and aluminium wire bonding. This makes them well suited to hybrid microelectronic circuits requiring robust and repeatable interconnections.
These conductors are printable pastes applied by screen printing to ceramic substrates and fired at high temperatures. Firing bonds the gold to the substrate, forming durable conductive tracks several microns thick.
Gold‑based thick film conductors are commonly used in high‑reliability environments involving thermal cycling, humidity, or chemical exposure, supporting applications in aerospace, military, medical, and high‑frequency electronics.
