What should you know about Flex Printed Circuit Boards

Flexible printed circuit boards were originally designed as a replacement for traditional wire harnesses. From early applications during World War 2, to the present, growth and proliferation of flex circuits and flexible printed circuit boards continues exponentially.

The Advantages of Flexible Printed Circuit Board Fabrication

Electronic devices have taken upon a prominent part of our everyday lives. The extensive range of devices from cell-phones to servers, regardless of their sizes and uses are now being designed to be flexible, lightweight and efficient. While they all come in diverse shapes, sizes and functionalities, there is one thing in common - they include flexible printed circuits boards.

Benefits of using Flex PCBs

  • Flexibility - the most prominent benefit.

    • The elastic nature of the flex PCB allows placement around edges and folds.

    • The flexible nature of the flex circuit boards are used in electronic devices that require 3 axes connections.

    • Very little or no wiring is required that eliminates wire connection failure and increases the reliability of the device.

  • Space and Weight Savings

    • Flex PCBs save up to 60% of the weight and space compared to Rigid PCB or wire harness applications.

  • Bending Cycles

    • Flex PCB use in 3D designs eliminates connectors, while the number of bending cycles can be as many as 200,000 (with standard material)

  • Anti-Vibration Benefits

    • Added flexibility and lighter weights allow the flex circuits to absorb and reduce the impact of the vibration to itself as well as any solder joints in connections.

  • Use in Harsh Environment

    • Flex circuits can be built with materials that are suitable to use in harsh operating environments (materials that have the following properties: waterproof, moisture proof, shock proof, high temperature oil, corrosion resistant).

  • Consistent Thin Inner Layers

  • Heavy Copper Layers

    • Heavy copper layers can be used for high-power uses with thin copper layers for flexibility.
