The use of soft and hard circuit boards?
In our daily life, circuit boards are mostly single-sided, double-sided, or multi-layer boards, rigid boards, metal-based circuit boards, aluminum, copper substrates, thermally conductive fiberboards, etc., do you know what a flexible and rigid circuit board is?
Rigid-flex circuit board: refers to a special circuit board made by pressing a rigid circuit board (PCB) and a flexible circuit board (FPC). The main board materials used are rigid board FR4 and flexible board polyimide (PI). Rigid and flexible circuit boards combine the rigid characteristics of rigid circuit boards and the advantages of flexible boards, so that the PCB is no longer a two-dimensional plane layer oil, but a three-dimensional internal wiring and arbitrary bending and folding. . It can replace a composite printed circuit board connected by multiple connectors, multiple cables and ribbon cables, and has the advantages of making the product stronger, more stable, lighter, and smaller.
The use of soft and hard circuit boards?
What is the purpose of the combination of soft and hard PCB board, where is it used, in fact, it is widely used in mobile phone cameras, notebook computers, laser printing, medical, military, aviation and other products.
Rigid and flexible circuit boards are the birth and development of FPC soft boards and PCB rigid boards, which gave birth to a new product of flexible and hard boards. Therefore, the flexible and hard circuit board is the flexible circuit board and the rigid circuit board. After pressing and other processes, they are combined according to the relevant process requirements to form a circuit that not only has the characteristics of the FPC flexible circuit board, but also has the characteristics of the PCB rigid circuit board. plate. As soon as this product was launched, it was deeply loved by people in the industry. The editor of Qichengzhiyi chats with everyone about the combination of soft and hard boards.
The characteristics of the soft and hard circuit board:
1. The flexible and rigid circuit board can be freely bent, folded, and wound, and can be moved and stretched freely in three-dimensional space.
2. The combination of soft and hard circuit board has good heat dissipation performance, and FPC can be used to reduce the size.
3. The combination of soft and hard circuit boards can achieve lightweight, miniaturization and thinning, so as to achieve the integration of component devices and wire connections.
4. Application areas of soft and hard circuit boards such as: MP3, MP4 players, portable CD players, home VCDs, DVDs, digital cameras, mobile phones and mobile phone batteries, medical, automotive and aerospace fields. FPC has become an important variety of epoxy copper clad laminates. Flexible copper clad laminate (FPC) with flexible function and epoxy resin as the base material!
5. The application range of flexible and hard circuit boards is also very wide.
The evaluation system of the circuit board factory should follow the following principles
