Soft and hard circuit board production process
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 board with FPC characteristics and PCB characteristics. In the past, two hard boards were connected by using soft boards and connectors to connect each other. In order to improve the reliability of the connection between the rigid board and the flexible board, the flexible board is directly fabricated between two rigid boards in the printed circuit board (PCB) factory, which can avoid the subsequent connection process, whether it is a rigid board manufacturer or FPC manufacturers are now able to supply rigid-flex boards. Under the demand for lightness and thinness of terminal products, the application range of flexible boards and rigid-flex boards will become broader.
High-end functional smart phones are still the main driving force for the development of the soft and hard circuit board market. Due to more functional requirements, such as powerful word processing functions, e-mail sending and receiving, digital camera pixel enhancement, etc., the application of soft and hard circuit boards in mobile phones has increased. Both static and dynamic applications can be designed with soft and hard boards. In the future, with digital TV Mobile phones have multiple functions, such as micro projectors and enhanced map functions. The combination of hardware and software is bound to be integrated and modularized.
1. The production process of soft and hard circuit board
Because the rigid-flex circuit board is a combination of FPC and PCB, the production of rigid-flex PCB should have both FPC production equipment and PCB production equipment. First, the electronic engineer draws the circuit and shape of the soft and hard board according to the needs, and then sends it to the factory that can produce the soft and hard circuit board. The CAM engineer processes and plans the relevant documents, and then arranges the FPC production line to produce FPC and PCB production lines are required to produce PCB. After these two soft and hard boards come out, according to the planning requirements of the electronic engineer, the FPC and PCB are seamlessly pressed through a pressing machine, and then through a series of details. The manufacturing process is a combination of hard and soft circuit boards. A very important link, because it is difficult to combine hard and soft circuit boards, and there are many details. Before shipment, a full inspection is generally required, because of its high value, so as to avoid loss of related benefits to both the supply and demand parties.
2. The advantages and disadvantages of the combination of soft and hard circuit boards
Advantages: The soft and hard circuit board has both the characteristics of FPC and the characteristics of PCB. Therefore, it can be used in some products with special requirements. It has both a certain flexible area and a certain rigid area, which is useful for saving internal products. Space, reduce the volume of the finished product, and improve the performance of the product are of great help.
Disadvantages: There are many production processes for the combination of soft and hard circuit boards, the production is difficult, the yield rate is low, the materials and manpower used are more, therefore, the price is relatively expensive and the production cycle is relatively long.
3. Application fields related to the combination of soft and hard circuit boards
The characteristics of the soft and hard circuit board determine its application field to cover all the application fields of FPC in PCB, such as:
mobile phone
Button board and side buttons, etc.
Computer and LCD screen
Motherboard and display screen, etc.
CD Walkman
Disk Drive
NOTEBOOK
Latest use:
Components such as the suspension circuit of the hard disk drive (HDD, hard disk drive) and the xe package board.
The evaluation system of the circuit board factory should follow the following principles
