Flexible PCB

Flexible PCB

Flexible printed circuit boards 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 with the circuit board. Flex boards are characterized by a distinctly patterned printed circuitry and component arrangement highlighted by a malleable base material.

Exploring the Many Advantages of Flex 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 a wired 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 require 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 PCB is 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 printed circuits include reduced material and packaging requirements, lower parts replacement costs and a reduction in assembly errors that could otherwise result in the need for repairs.


All of these benefits make flex circuit boards ideally suited for a wide range of applications in industries such as Military, Transportation, Medical, Consumer Electronics, Automotive, Aerospace, Communications and Industrial.
