Advantages of soft and hard circuit boards: Soft and hard combination boards have both the characteristics of FPC and the characteristics of PCB. Therefore, they can be used in some products with special requirements, with both a certain flexible area and a certain rigid area, which is very helpful in saving internal space, reducing finished product volume, and improving product performance.

Disadvantages of soft and hard combination circuit boards: The production process of soft and hard combination boards is complex, with high production difficulty, low yield rate, and a large amount of materials and manpower required. Therefore, the production cycle is relatively long, and their prices are relatively expensive.

Flexible circuit boards are very different from rigid circuit boards. They are a highly reliable and excellent flexible printed circuit board made of polyimide or polyester film as the substrate. Their wiring density is high, weight is light, and thickness is thin, so they require strict execution from design to production. They are mainly used in electronic products such as mobile phones, laptops, PDAs, digital cameras, LCMs, etc. Its design is different from that of a rigid circuit board, so what is the focus of flexible circuit board design? Now the editor will officially introduce its key points to everyone:

1. In the design of flexible circuit boards, attention should be paid to three-dimensional space, as it can save space and reduce board layers in bending and flexible applications.

2. Compared to rigid boards, flexible circuit boards have lower tolerance requirements and allow for a larger tolerance range.

3. Because the wings of the flexible circuit board can be bent, it is designed to be slightly longer than required.

4. The characteristics of flexible circuit boards should be demonstrated.
