Application scope and advantages of flexible circuit board

Since the creation of flexible and rigid pcb circuit boards, whether these types are superior to traditional rigid circuit boards has been controversial.

One can argue that one circuit board is better than another. But it is not as much as the market needs. Previously, the device had to be designed to fit the circuit board. Today, PCB designs need to be created to accommodate devices.

The reason is that modern electronic equipment is becoming smaller and smaller, but it is expected to be faster. In addition, they require circuits to transmit information quickly and accurately without degradation. Flexible circuit board can meet this requirement.

The advantages of flexible circuit boards prove that they are the right solution to meet the needs of today's electronic equipment. You can understand the characteristics and application scenarios of flexible circuit boards

Reduce PCB size and weight: Flexible circuits are known to be thin and light. They can also be folded or placed in a confined space. All of these aspects result in a reduction in PCB size and weight. This can be a huge advantage over harnesses.

Design diversity: Flexible circuits can accept connectors or components used in any type of rigid PCB. It can be designed using different types of components and methods, such as crimping contacts, ZIF connectors, and direct soldering to PCB methods. They can also be designed for RF or EMI shielding for certain applications.

Cost effectiveness: As the size and weight of PCB package will be reduced, it will also reduce the costs related to materials and manufacturing. The assembly process requires fewer machines. A simpler assembly process will result in fewer errors in the final product.

Flexible circuit board, also known as "soft board", is a printed circuit made of flexible insulating substrate, which has many advantages that hard printed circuit boards do not have. For example, it can bend, wind and fold freely, can be arranged arbitrarily according to the space layout requirements, and can move and expand freely in three-dimensional space, so as to achieve the integration of component assembly and wire connection. The volume of electronic products can be greatly reduced by using FPC, which is suitable for the development of electronic products in the direction of high density, miniaturization and high reliability. Therefore, flexible circuit board is widely used.

1. Mobile phone

Focus on the light weight and thin thickness of the flexible circuit board. It can effectively save the volume of the product, and easily connect the battery, microphone and buttons.

2. Computer and LCD screen

The integrated circuit configuration of the flexible circuit board and the thin thickness are used. The digital signal is converted into a picture and displayed on the LCD screen.

3. CD Walkman

Focus on the three-dimensional assembly characteristics and thin thickness of flexible circuit boards. Turn the huge CD into a companion you can take with you.

4. Disk drive

Both hard disks and floppy disks rely heavily on the high softness of FPC and the ultra-thin thickness of 0.1mm to complete fast data reading. Whether PC or NOTEBOOK

5. Latest use

The mounting circuit of the hard disk drive (HDD) and the components of the xe packaging board. The wireless charging coil array concentrates the electromagnetic field in a certain area to reduce the space transmission consumption, thus improving the power conversion efficiency.
