Double-Sided Rigid-Flex PCB

Double Sided Flex PCB Description

Double Sided Printed Circuit Boards offer two conductor layers separated by a dielectric, usually polyimide. Coverlayers may be used on one or both sides. Plated through holes may or may not be featured to interconnect traces on opposite sides of the dielectric.Double Sided Printed Circuit Board provides the ability to access circuit traces from both the top and bottom sides of the circuit offering greater flexibility in design and functionality. Properly designed and utilized, Double Sided Printed Circuit Boards offer the same level of dynamic flexing (repetitive movement) as do single-sided flex, providing a much wider range of application uses due to its ability to carry more complex circuit layouts.

Benefits of Double-Sided Rigid-Flexible Printed Circuits Boards

  1. Space-saving:

    Double-sided rigid-flex PCBs allow for compact designs by combining both rigid and flexible sections into a single board. This saves space compared to using separate rigid and flexible boards.

  2. Improved reliability:

    Rigid-flex PCBs offer improved reliability compared to traditional rigid PCBs. The flexible sections provide better resistance to vibrations, shocks, and thermal expansion, reducing the risk of component failure.

  3. Enhanced design flexibility:

    Double-sided rigid-flex PCBs offer greater design flexibility compared to rigid PCBs. The flexible sections can be bent, folded, or twisted to fit into tight spaces or irregular shapes, allowing for more creative and innovative designs.

  4. Reduced assembly time and cost:

    By combining rigid and flexible sections into a single board, the assembly process is simplified, leading to reduced assembly time and cost. There is no need for separate connectors or cables to connect rigid and flexible boards.

  5. Improved signal integrity:

    Double-sided rigid-flex PCBs offer better signal integrity compared to using separate rigid and flexible boards. The shorter interconnects and reduced number of connectors result in lower signal loss and improved signal quality.

  6. Increased durability:

    Rigid-flex PCBs are more durable compared to traditional rigid PCBs. The flexible sections can withstand repeated bending and flexing without compromising the integrity of the circuit, making them suitable for applications with high mechanical stress.

Double sided Rigid-Flex Application

Double-sided rigid-flex PCBs are typically used in applications where there is a need for both rigid and flexible sections within the same circuit board. Some common applications include:

  1. Portable Electronics:

    Double-sided rigid-flex PCBs are commonly used in portable electronic devices such as smartphones, tablets, and wearable devices. The flexible sections allow for compact and lightweight designs, while the rigid sections provide stability and support for components.

  2. Medical Devices:

    Rigid-flex PCBs are often used in medical devices where space is limited and reliability is crucial. They can be used in devices such as pacemakers, hearing aids, and medical implants.

  3. Aerospace and Defense:

    Rigid-flex PCBs are used in aerospace and defense applications where there is a need for lightweight and compact designs. They are commonly used in avionics systems, satellites, and military equipment.

  4. Automotive Electronics:

    Rigid-flex PCBs are used in automotive electronics where there is a need for flexible connections in areas with vibrations and temperature variations. They are commonly used in dashboard controls, infotainment systems, and engine control units.

  5. Industrial Equipment:

    Rigid-flex PCBs are used in industrial equipment where there is a need for reliable and durable circuit boards. They are commonly used in control systems, robotics, and automation equipment.

There are many benefits to Flexible Printed Circuits including

1. Assembly Error Reduction – With accurate designs and automated production, flex circuits eliminate human errors once involved in hand-built wire harnesses. With the exception of production-induced errors, circuits are ONLY routed to those points called for by the accurate design plan.

2. Decreased Assembly Time and Costs – Flex circuits require less manual labor during assembly and reduce production errors. Flex circuits have an intrinsic ability to integrate form, fit and function. Flex circuits eliminate the high cost of routing, wrapping and soldering wires. Complete interconnection systems are installed or replaced, rather than individual hard PC boards. As a result, wiring errors are eliminated and hence manufacturing costs are reduced. Whether it is a low volume production with a complex circuit or high volume production with a simple circuit, assembly time and costs are decreased.

3. Design Freedom – Unlike rigid boards, flex circuits are not restricted to two dimensions. Because they are as flexible as wires or ribbon cables, flex circuit design options are endless. At Flexible Circuit, we pride ourselves on taking on the most complex of design challenges. Flex circuits can be designed to meet highly complex and unimaginable configurations while being able to operate in the most hostile environments.
