https://www.x-pcb.com/product/rigid-flex-pcb-manufacturer/Flexible PCB is also referred to as the flex circuit. It is an excellent addition to the electronic components. This particular type of printed circuit board can twist and fold. However, the bending ability depends on your requirements.
Flexible PCBs contain a thin insulating polymer film along with conductive circuit patterns. These circuit boards are lightweight, thin, and small. For these capabilities, the use of flexible PCBs is increasing rapidly. You can get the best quality flexible printed circuit boards from a flexible PCB supplier.
Different Types Of Flexible PCB
There are mainly four types of flexible circuit boards available on the market. The different types of flexible PCB include;
Single-Sided Flexible Circuits
These circuits are one of the most common designs. There are various reasons behind the popularity of single-sided flexible circuits. These flexible circuit boards are the least expensive.
Besides, these circuit boards contain highly effective variants for various flex applications. The construction material for these circuit boards includes conductive links. Rigid flex PCB manufacturer also use etching metal to make these circuit boards. The etched metals and ink produce the required circuit patterns on the surface of the flexible boards.
Double-Sided Flexible Circuits
It is also another common design for flexible circuit boards. It is beneficial for all those applicants that need high-density interconnection of circuits. These circuit boards feature two metal layers connected with a plated-through hole. It contains successive layers of adhesive and cover film on both sides of the base film.
Multilayer Flex Printed Circuits
A Multilayer circuit is a combination of single or double-sided flex circuits. Similarly, as the double-sided circuit boards, multilayer flex printed circuits are useful for high-density demanding applications.
These circuit boards contain some specific properties that resemble rigid circuits. However, for its multilayer structure, here you get a sophisticated design. These circuit boards help to resolve specific electrical and electronic issues.
Rigid-Flex Printed Circuits
As the name suggests, this circuit board combines both flexible and rigid printed circuit boards. The rigid part of the circuit boards supports all the components and reinforces the connectors. And the flexible part of the board provides the entire connectivity for various rigid sections.
The main purpose of developing hybrid circuit boards is to produce a reliable connection. These circuit boards create a lightweight interconnection structure. Here you also can see a higher degree of engineering complexity.
When to Use Flexible PCB?
Flexible printed circuit boards consist of polyimide that endures extreme temperatures. It can even handle temperatures between 200 and 400C. So, in such cases, a flex circuit is used for high-temperature and density applications. Flexible PCB has good uses in the gas and oil industries.
As these circuit boards can endure heat, they are also resistant to chemicals, UV exposure, and radiation. Therefore flexible PCB is highly useful for various applications that deal with chemicals and high temperatures.
