Advantages of Flexible PCB
1. Bendability:
Flexible PCB can be used flexibly in applications that require bending. It can adapt to irregular shapes and curved designs.
2. Space saving:
Due to the thin design of flexible PCBs, a lot of space can be saved.
3. Weight reduction:
Flexible PCBs are lighter and can reduce the overall product weight compared with rigid PCBs. Therefore, they are suitable for lightweight design.
4. Reliability:
Flexible PCB reduces the connection points. This cuts the failure rate and boosts product reliability.
5. Cost reduction:
The cost to manufacture flexible PCBs is low. The assembly process can be simplified, saving costs.
6. Strong adaptability:
Flexible PCB is suitable for many uses. These include curved and wearable electronic devices.
Flexible PCB Applications
Flex PCB has its own place of application in various industries, from LCD to the automotive field. It is usually used as a connector in different sectors. The flexible PCB board is flexible and space-saving. So, it is prevalent in narrow spaces where the capability of rigid PCBs is limited.
- Electronic assemblies: Flex PCB boards can be used as passive wiring structures. They enable the connection of electronic parts through their flexible design. For example, capacitors, resistors, and integrated circuits are noteworthy.
- Automotive field: Flexible PCBs can be used in under-hood controls, apparatus panels, or ABS systems.
- Computer peripherals: Flexible PCBs are also prevalent on the moving print head of printers. They submit the signals to move arms to finish the final printing.
- Manufacturing & medical devices: Flex circuit boards established the interconnections in the compacted package. Because of its flexibility, they are well-performing in these devices.

FAQs
Why Choose Chinese Flex PCB Manufacturers?
There may be some misunderstandings against Chinese PCB manufacturers. Some may think that they provide cheap but inferior products. Actually, no matter what country it is, a high price doesn’t always mean high quality. It depends on various factors. However, in most cases, a high price may determine the high quality of the product. They typically come with durable PCB materials and sophisticated PCB designs. In addition, they resemble excellent PCB manufacturing and assembly equipment. If the PCB company has its R&D basic, it might price relatively high for its products.
There are a few reasons for the lower product prices of Chinese manufacturers. It is not the unreliable product quality or inferior PCB fabrication and assembly equipment but the local market and policy. Reasons why you should choose Chinese flex PCB manufacturers are:
A crowded market stimulates advanced technology
With over 15 years of experience, the Chinese PCB market has a well-established system of PCB services. Fierce competition in this market encourages Chinese PCB manufacturers. It enhances its manufacturing technology to offer competitive products continuously. However, market dynamics make prices generally lower than in Europe.
Lower-cost labour with efficient production
China’s competitive employment market also produces lots of efficient labour with lower costs. China nowadays can achieve mass PCB manufacturing and assembly in a highly efficient way. It lowers the production time and cost. Besides, it provides an affordable price with the same quality as other developed countries.
High-quality PCB service
As the PCB market matures, Chinese PCB manufacturers can provide satisfying services. Their full-service includes full-service from PCB manufacturing to deliver only your requirements online. The Internet provides a chance for every PCB company to buy PCB online.
Flex PCB material
Flex PCBs are usually made of materials according to their applications. Various materials can be used to produce flexible printed circuit boards. For example, Teflon, polyimide, FR4 epoxy, or other laminates that combine glass with resin coatings are noteworthy.
Using PCB materials to design the flex PCBs has some considerations.
Here are them:
- Dielectric
- Mitigated loss factors
- Flame retardancy
- Higher temperatures for glass transition
- Thermal performance
- Dimensional stability
Flex PCB Design Guide
Flex PCB thickness and flex PCB bend radius are necessary for PCB design. It dominates the quality of flex PCB design. Usually, the flexible printed circuit board thickness is 0.05mm to 0.8 mm. A flex-printed circuit board’s bend radius should be at least ten times the material thickness. Maintaining this radius at least 500 um away from plated through holes is crucial. These holes should include reliefs for slits in the circuit. Additionally, incorporating tear stops is essential for reinforcement.
