Flex/Rigid Flex Technology

Rigid-Flex PCB Technology

We produce multilayered flex and rigid printed circuit boards which are interconnecting layers which help our electronics engineers / design engineers to have the flexibility to use them as per their custom application / product design requirements which will also reduce cost.

Rigid-flex PCB's is not just ordinary flexible printed circuit board. It's composition substrate lamination into single board that creates many opportunities and can also allow circuit board / electronic device manufacturing designers to find substitute of multiple printed circuit board interconnection with connectors, wires and ribbon cable to create a single printed circuit board with a view to improve overall performance, reliability and scalability in the process.

TechnoTronix brings tomorrow's innovations today. Our consistent focus on innovation and developing new technologies is nurtured through continuous learning, excellence, distinction, investment and strong customer and supplier relationships. At TechnoTronix, we believe we possess what it takes to make us the ideal partner to provide electronics manufacturing, engineering and design services for your emerging technologies in mechatronics, green energy, and nanotechnology.

Benefits of Rigid Flex PCBs

  • Space requirements can be minimized by applying 3D (Rigid / Flex)
  • By removing the need for connectors and cables between the individual rigid parts the board size and overall system weight can be reduced.
  • By maximizing space, there is often a lower count in parts.
  • Less solder joints assure higher connection reliability.
  • Handling during assembly is easier in comparison with flexible boards.
  • Simplified PCB assembly processes.
  • Integrated ZIF contacts provide simple modular interfaces to the system environment.
  • Test conditions are simplified. A complete test prior to installation becomes possible.
  • Logistical and assembly costs are significantly reduced with flex-rigid boards.
  • It is possible to increase the complexity of mechanical designs, which also improves the degree of freedom for optimized housing solutions.
