What is Flexible PCB?
Flexible printed circuit boards, also called Flexible PCBs or Flex PCBs, derive their name for their ability to enable the circuitry to be designed to fit the electronic device or product, as opposed to building the device to conform to the circuit board. Immersion Tin PCB are characterized by a distinctly patterned printed circuitry and component arrangement highlighted by a malleable base material.
What are Advantages of Flexible Printed Circuit Boards?
Flexible printed circuit boards offer a number of potential benefits including:
Saving Space. Flex PCB design requires only about 10 percent of the space and weight of an ordinary circuit board assembly, offering greater installation and packaging freedom. The inherent flexibility also permits tighter bend capabilities.
Maximum Reliability. A flexible printed circuit board requires fewer interconnects, which in turn requires fewer contact crimps, connectors and solder joints. Simply put, a flexible PCB board does not contain as many potential sources for failure, which enhances their reliability.
Enhanced Capabilities. The flexible printed circuits boards are compatible with virtually any type of connector or component and works well with options such as ZIP connectors. They also perform extremely well in extreme temperatures and offer superior resistance to radiation and chemicals.
Cost Savings. Cost-saving advantages of Flexible PCBs include reduced material and packaging demands, lower parts replacement costs and assembly errors that could result in the need for repairs.
Thsse benefits make flex PCBs ideally fit for a wide range of applications in industries such as Military, Transportation, Medical, Consumer Electronics, Automotive, Aerospace, Communications and Industrial.

Flexible Circuit Fabrication
A Flex Printed Circuit or Flex PCB is a basically a flexible Base material, with a patterned arrangement of printed circuitry on Copper and components, with or without flexible overlay. These flexible electronic assemblies may be fabricated using the same components used for rigid printed circuit boards, but allowing the board to conform to a desired shape (flex) during its application.Â
Flexible PCB / FPCB ApplicationsÂ
FPCBs are used widely in everyday technology and electronics in addition to high-end, complex completed components. Two of the most prominent examples of flexible circuit usage is in modern portable electronics, devices, hard disk drives and desktop printers.Â
Flexible circuits are also used extensively in other applications and industries including:Â
CommunicationsÂ
Consumer ElectronicsÂ
AutomotiveÂ
MedicalÂ
IndustrialÂ
AerospaceÂ
MilitaryÂ
Transportation
In Automotive, Transportation they are extensively used due to their improved resistance to vibrations and movement.
