PET Conductive Silver Ink Circuitry
Conductive Silver Ink silkscreen printed onto a PET (Polyethylene Terephthalate) film, creating a flexible circuit, double-layer circuitry could be achieved by via.
It’s a cost-effective alternative to copper foil circuits (FPC), making it ideal for lightweight, low-cost electronics devices.
Advantages
Superior Flexibility: The PET substrate is highly durable and can endure repeated bending, with a minimum bending radius as small as 3 mm. This makes it perfect for dynamic and curved applications.
High Electrical Conductivity: The silver paste delivers a volume resistivity of 5×10⁻⁵ Ω·cm, which is roughly 10% of the conductivity of solid silver.
Simplified Manufacturing: By directly printing the circuits, eliminate the need for traditional etching processes, which significantly shortens the production cycle and reduces complexity.
Significant Cost Savings: This method can reduce costs by as much as 50% compared to traditional FPC circuits.
Ultra-Thin Design: The total thickness of the circuit 0.1 to 0.3 mm, including both the substrate and the conductive silver paste layers
