About P-Flex® (

P-Flex® is a Flex PCB manufactured by Pure Additive™ processing.
Conventional electronic circuits are made using a process called photolithography where copper foil is applied to the entire surface before unnecessary parts are melted away. The Pure Additive™ processing developed by Elephantech takes the totally opposite manufacturing approach of inkjet printing silver nanoparticles only where necessary before applying electroless copper plating.
