Episode 2: Conductor Traces – The Backbone of Thick Film Circuits

Conductor traces are crucial, acting like arteries by efficiently delivering power and signals. Made from silver, gold, or copper pastes, they are screen-printed on substrates and fired at 850°C for durability. Silver is cost-effective for wearables; gold offers corrosion resistance for biosensors; copper provides high conductivity for heaters. Despite challenges like thermal expansion mismatches and silver migration, these traces support diverse applications from heaters to smartwatches.
