Flexible Circuit Assembly

Flexible circuits are thin, lightweight, and compact devices that are gaining traction in many markets. This is mainly because electrical and electronic devices or parts are miniature sized or fitted in compact spaces. This trend is already a game changer and is estimated to last for the long term. We, at Automated Assembly, have developed roll-to-roll assembly, SMT-Flex®, that offers us a competitive edge in this market segment. Automated Assembly Corporation is the first company to manufacture SMTFlex® in roll-to-roll format for both mid to high-volume production runs, and also utilizing smaller volumes to meet our customers’ needs.

Beneficial Features of Our Flexible Circuit Assembly

Flexible circuits are just as robust as PCBs and can handle the thermal shock of an automotive brake system. We have worked with many SMT components and offer custom flex assembly that suits your exact application requirements. Here are some beneficial features of our flexible circuit assemblies.

  • Flexibility: While most times, a standard flexible circuit assembly is done on polyimide, polyester and PEN based films, we offer next generation flex technology, Wire-Write, that allows processing on paper, cloth, vinyl, and so on. Aside from this material flexibility, our Wire-Write assembly is customizable and can conform to various shapes and contours. It can be bent, twisted, and folded without compromising performance, making it ideal for space-constrained environments and complex designs.
  • Automation: We use a high level of automation in our manufacturing techniques. At Automated Assembly Corporation your flexible circuits are assembled using SMTFlex® technology utilizing our high-speed automated placements. All our automation is optically guided and we write the code in-house.
  • High-Density Interconnections: We assemble flexible assemblies for small-sized products with multiple functionalities. We can achieve this by ensuring high-density interconnects using advanced manufacturing techniques. This prevents signal losses and improves electrical performance.
  • Durability: flexible circuit assemblies are highly durable and resistant to shocks, vibration, and harsh environmental parameters. It remains structurally stable in any harsh environment or mechanical stress, without compromising on performance.
  • Weight: flexible circuits are lightweight, which means they do not add excess weight to the product. Hence, they are preferred in crucial applications in aerospace, defense, automotive, and so on, where weight reduction is a crucial factor.
  • EMI Shielding: We offer flexible shields to prevent electromagnetic interference in our flexible circuit assembly. These shields offer protection to sensitive electronic components from any noise or EMI.
