Benefits of 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.

Space & Weight Savings: With thicknesses as low as 0.05mm, flex PCBs are ideal for wearables and medical implants.
Dynamic Flexibility: Can withstand over 200,000 bending cycles (tested per IPC-6013 standards).
Simplified Assembly: Reduce connector use by up to 70%, lowering costs and failure points.
High-Temperature Resistance: PI base materials stable up to 300°C, suitable for automotive and aerospace.
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.

Applications for Flex Printed Circuit Boards

The continuous miniaturization of devices has driven printed circuit boards to become smaller and denser and require more capabilities. Applications we supply mini flexible PCBs include:

Consumer Electronics
Medical devices – wearables
Industrial sensors
Motion systems
Semiconductor test and manufacturing devices
Semiconductor packaging
Fuel pumps

Flexible PCB FAQs

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.
