Types and advantages of flexible pcb circuit board
The PCBA board is the finished product after the PCB board has been processed by SMT processing, DIP plug-in and PCBA test. Almost all electronic products need to use PCBA board. With the continuous development of the electronics industry, the size of components is getting smaller and smaller, and the density is getting larger and larger. Flexible pcb circuit board have emerged.
Flexible pcb circuit board is a printed circuit made of a flexible insulating substrate. Previously, this interconnection technology was implemented by means of wire interconnection. The flexible pcb circuit board provides excellent electrical conductivity to meet the design needs of smaller and higher density installations, as well as to reduce assembly processes and enhance reliability. Soft boards are the only solution to meet the miniaturization and movement requirements of electronic products.
First, the type of flexible pcb circuit board
1, Two-way access flexible pcb circuit board, which is a single-sided flexible circuit. The purpose of manufacturing this circuit is to connect conductive materials from both sides of the flexible pcb circuit board.
2, Double-sided flexible pcb circuit board, is a circuit with two conductive layers, two conductive layers are located on the two sides of the basic layer in the circuit; for your specific requirements, you can form line pattern on both sides of the substrate sheet, the routes on the two sides can be interconnected by copper-plated through holes.
3, Multi-layer flexible pcb circuit board, is the combination of several single-sided circuits or double-sided circuits with complex interconnections, in the multi-layer design often need to use shielding technology and surface mount technology.
4,The hard and flexible pcb circuit board integrates the advantages of both rigid printed circuit boards and flexible pcb circuit board. The circuits are usually interconnected by plated through holes between the soft and hard boards.
Second, the advantages of the flexible pcb circuit board
One of the main benefits of flexible pcb circuit board is the ability to implement almost error-free wiring, replacing labor-intensive manual wiring. In addition to the hard board, the flexible pcb circuit board can also be designed into a complex three-dimensional structure because they can be bent into various shapes. As the name suggests, materials used in flexible pcb circuit board can be bent back and forth countless times, which means they can be used in highly repetitive applications such as on print heads. When a PCBA processor needs to consider the weight of the product, the flexible pcb circuit board is a very good substitute for rigid boards and wires because its dielectric material and conductor lines are very thin.
With the development of technology, it is believed that in the near future, the flexible pcb circuit board will become smaller and more complex, and the cost of assembly will become higher and higher. So for PCB practitioners, to be able to stand in a higher position in the future, you need to constantly understand, learn and master more about flexible pcb circuit board.
