Our Flexible Printed Circuit Board Capabilities

Let Rapid Flex Circuits be your one-stop shop that addresses your flex circuit design, fabrication, and assembly needs. We can help you reduce product handling and lead time associated with outsourcing such tasks.
Send us a sketch or diagram of your idea, and we’ll design a cost-effective interconnect solution based on it. For your convenience, we also do component assembly for connectors, various surface mount components, and many others. We invite you to learn more about our common and artwork flexible printed circuit board capabilities:
