Analysis of the advantages and disadvantages of flexible pcb

FS Technology believes that FPC has many advantages, such as space saving, weight reduction and high flexibility. As people's requirements for electronic products are getting higher and higher, the demand for flexible PCBs is also increasing. The unique characteristics of flexible circuit boards (FPCs) make them an alternative to rigid circuit boards and traditional wiring schemes in many applications. With the development of flexible pcb, many downstream industries have benefited from it, and the output has become higher and higher. Among them, the fastest growing part is the internal connection line of computer hard disk drive (HDD). The second fastest growing area is new integrated circuit packaging. The market potential of flexible circuit technology in portable devices such as cell phones is very large. Next, FS Tech will objectively explain the advantages and disadvantages of flexible pcb.

Advantages and disadvantages of flexible circuit boards

Advantages of FPC PCB

1. It can be freely bent, wound and folded, and can be arbitrarily arranged according to the requirements of spatial layout, and can be freely moved and expanded in three-dimensional space, thereby realizing the integration of component assembly and wiring;
2. The use of flexible circuit boards can greatly reduce the volume and weight of electronic products;
3. The flexible circuit board also has the advantages of good heat dissipation, good weldability, easy assembly and low comprehensive cost. The design of the combination of soft and hard also makes up for the slight deficiency of the flexible substrate in the bearing capacity of the component to a certain extent;

Disadvantages of flex pcb

1. High one-time initial cost: Since the flexible PCB circuit board is designed and manufactured for special applications, the initial circuit design, wiring and photographic film costs are high. Unless there is a special need to use a flexible PCB, it is best not to use it in small quantities. Of course, you don't have to worry about this problem if you purchased a flexible PCB from FSPCB. FS Tech is always customer-centric. We not only manufacture PCBs with the lowest cost, but are more willing to spread PCB-related knowledge. strong reason.
2. Flexible PCB is difficult to replace and repair: Once the flexible PCB circuit board is made, the change must start from the basic drawing or the prepared photo program, so it is not easy to change. Its surface is covered with a protective film, which must be removed before repairing, and restored after repairing.
3. Limited size: Flexible PCB boards are usually manufactured using batch processes when they are not popular. Therefore, due to the size of the production equipment, they cannot be made very long or very wide. This is also the reason why soft PCBs are expensive.
4. Improper operation is easy to damage: improper operation of assembly personnel can easily damage the soft circuit, and its welding and rework need to be operated by trained personnel. If you are not very familiar with this aspect, you can consult FS Tech at any time, and we will answer all pcb problems for you.
