Flex PCB(FPC)
Flex PCB(Flexible printed circuit board, Flex Circuit Board, FCB, FCP, Flexible FPC, FPCB or soft boards) is a patterned arrangement of printed circuitry and components that utilizes flexible base material with or without flexible cover lay. The IPC defines a flexible printed circuit as “a patterned arrangement of printed circuitry and components that utilizes flexible base material with or without flexible cover lay.” This definition, while basic, illustrates what you can expect from a flex PCB – a bendable printed circuit that is made of a flexible film.
Types of Flexible Printed Circuit Boards
Since they have been applied across a wide range of industries, flex PCBs have grown in complexity. Listed below are some of today’s most common types of flexible printed circuit boards.
Single-Sided Flexible Circuits
This type of PCB is the most commonly used and simplest available. The flex PCB has only one conductor layer and is printed on one side. Due to their simplicity and low weight, these printed circuits are found in most calculators. They are the most affordable flex PCBs on the market.
Double-Sided Flexible Circuits
The double-sided flex PCBs offer enhanced power handling capabilities and circuit density by printing both sides of a dielectric film and connecting them with plated through holes. However, single-sided flex PCBs are somewhat more expensive to produce because of their increased power.
Multi-Layer Flex Circuit Boards
The construction of multi-layer flex circuits makes them more expensive than their counterparts due to the complexity of their construction. These circuits are commonly used in aerospace and military applications that justify their cost and capabilities.

Applications of Flex PCB
In recent years, flexible PCBs have become far more complex as they have been applied to industries across the board. They are suitable for a number of applications that rigid circuit boards cannot.
Computer technology makes up a third of flexible printed circuit sales – from printers to scanners to smart phones. Flex PCBs provide heavy computing power without sacrificing weight restrictions as the market demands smaller and more advanced handheld technology.
It is estimated that the second largest market for flex PCBs is the automotive industry. Cars look substantially different than they did at the beginning of the decade, as well as their hardware. The use of flex PCBs allows for both space allocations and thermal performance as cars begin to incorporate sensors and electronics like climate control and GPS software, as well as dashboards and rear-view cameras.
It is no wonder that flex PCBs are the perfect choice for aerospace applications such as satellites because they are able to handle extreme temperatures and vibrations. It is also possible for them to take on unusual shapes and replace connectors that are more susceptible to failure on spacecraft.
In the past few decades, wearable devices have become a key feature of medical technology. As flexible printed circuit boards can mimic the shapes found in the body, they are more durable, allowing these devices to withstand wear and tear. Hearing aids, vital sensors, and more use flexible printed circuit boards to achieve high performance.
