Koartan manufactures a comprehensive range of Gold, Silver, Palladium and Platinum conductive thick-film pastes for a wide variety of Microelectronic Hybrid applications.
Their range of Silver-bearing pastes includes conductor materials, termination metallisation’s, plateable inks, low-temperature firing from 400°C, and also lead- & cadmium-free products.
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 materials.
Koartan 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.

Further Information
What are Thick Film Silver Conductors
Thick film silver conductors are printable conductive pastes used to form electrical interconnects, terminations, and conductive features in thick film and hybrid microelectronic circuits.
Applied by screen printing onto ceramic or compatible substrates and subsequently fired, these materials create continuous silver‑based conductive paths that combine high electrical conductivity with cost‑effective processing.
Thick film silver conductors are widely used across power electronics, hybrid circuits, and multilayer ceramic assemblies.
Key characteristics of thick film silver conductors include:
- Silver offers very high electrical conductivity at a lower cost than noble metal alternatives, making it suitable for many interconnect and power applications.
- Thick film silver conductors are screen printed and fired, forming durable conductive tracks bonded to the substrate.
- These materials are commonly used where solderable surfaces are required for reliable component attachment.
- Because silver can migrate in humid or biased environments, appropriate design measures are typically used to ensure long term reliability.
