Classification and advantages of soft and hard board


The rigid-flex board is a new type of printed circuit board that combines the durability of a rigid PCB and the adaptability of a flexible PCB. Among all types of PCBs, the combination of rigid and flexible is the most resistant to harsh environments. The bonding board has the characteristics of FPC and PCB at the same time. Therefore, it can be used in some products with special requirements. It has a certain flexible area and a certain rigid area, which can save the internal space of the product and reduce the volume of the product. , It is of great help to improve the function of the product.

  1. The advantages of soft and hard board
    1. Light weight
    2. Interposer is thin
    3. Short transmission path
    4. Small through hole
    5. Foldable without affecting the signal transmission function.
    6. It can prevent electrostatic interference.
    7. Chemical changes are stable, stable, and highly reliable.
    8. Conducive to the planning of related products, can reduce installation man-hours and faults, and improve the service life of related products.
    9. Less noise, high trust
    10. It is flexible and can be wired three-dimensionally, and the shape can be changed according to space constraints.
    11. High and low temperature resistance, flame resistance.
    12. The volume of the product used is reduced, the weight is greatly reduced, the function is increased, and the cost is reduced.



Classification and advantages of soft and hard board

2. Classification of rigid-flex board
If it is classified according to the manufacturing process, the method of joining the soft board and the hard board can be divided into two types of products: the soft-hard composite board and the soft-hard composite board. Combination, during which there are common blind and buried hole planning, which can have higher density circuit planning, and the technology of flexible and hard board is to separate the soft and hard boards and then press them to form a single circuit board. , There is a plan for signal connection but no through holes. But nowadays, "flexible and rigid combined boards" are used to collectively refer to all rigid and flexible combined board products without subdividing the two.

3. The use of soft and hard board
The characteristics of the soft and hard board determine that its application areas cover all the application areas of FPC and PCB, such as: mobile phones, keypads and side buttons, computers and LCD screens, motherboards and displays, CD players, disk drives, NOTEBOOK, etc., and the latest use of the soft and hard board is the hard disk drive (HDD, hard disk drive).
