Flexible PCBs

Flexible printed circuit boards offer many potential benefits so that flexible PCBs are now being used widely to replace traditional FR4 PCB in various different applications.

• Reduce weight and space: Thickness can be as thin as .004 inches (.10mm) in total.

• Reduce assembly costs: Flex circuits can be tested prior to assembly of components.

• High tensile strength: can be significantly warped/deformed without breakage.

• High Heat Dissipation: Owing to the compact designs and denser device populations, shorter thermal paths are created. This helps dissipate the heat faster than a rigid circuit.

• Streamlined Designs Made Possible: Flexible circuit board technologies have helped improve circuit geometries. The components can be easily surface mounted onto the boards, thus simplifying the overall design.

• 1. What is a flexible PCB?

  Flexible PCB, also known as flex prints or flex circuits, is a special type of circuit board that you can bend into the desired shape. They are widely used for high-density and high-temperature applications.

• 2. What is the advantage of flexible PCB?

  In many applications, flexible PCBs can eliminate the need (and cost) of connectors and cables, improving connection reliability and reducing assembly time, assembly costs and overall device dimensions.

• 3. What is rigid PCB vs flexible PCB?

  As the names suggest, a rigid PCB is a circuit board built on a rigid base layer that cannot bend, while a flexible PCB, also called a flex circuit, is built on a flexible base capable of bending, twisting and folding.

• 4. Why are Flex PCBs so expensive?

  The manufacturing process of Flexible PCB is too lengthy, complex and needs a special environment, which makes it too expensive to design.

• 5. What are the disadvantages of rigid flex PCB?

  The production process of Flex-rigid PCB boards are numerous, the production is difficult, the yield is low, the pcb materials and manpower wasted more. Therefore, the price is relatively expensive and the production cycle is relatively long.

• 6. What are the characteristics of flexible PCB?

  Flexible Printed Circuit (FPC) a highly flexible and excellent flexible printed circuit board made of polyimide or polyester film. It has the characteristics of high wiring density, light weight, thin thickness and good bending property.

• 7. What material is used for flex PCB?

  Leading conducting material of flexible PCB is copper or copper foil and sometimes alloy is also used including aluminum, nickel, gold and silver etc. Apart from conduction, conductor layer should be flexibility resistant.

• 8. What is the minimum thickness of flexible PCB?

  PCB boards come in various thicknesses. A standard two-layer board has a minimum thickness of 14 mils and a maximum of 32 mils.
