Turnkey PCB Assembly Services for Prototyping and Volume Production

Rigid-Flex PCB

Rigao Electronics manufactured many rigid-flex Printed Circuit Boards for our clients to meet their design requirements, pcb design and fabrication of rigid flex circuit boards,saving the internal space of products, reducing the volume of finished products and improving the performance of products. This kind of rigid-flex PCB boards also can be manufactured with blind & buried via, epoxy resin or copper filled via, Controlled Impedance process as well.
