TPU printed circuit

Innovative electronic solutions, flexible and durable conductive circuits.

TPU printed circuit technology leverages TPU (thermoplastic polyurethane), a skin-friendly and durable material widely used in flexible electronic devices. By printing silver paste conductive circuits on TPU substrates, we create flexible circuits with excellent performance to meet the needs of modern electronic devices for lightness, durability, and efficiency.
