Types and benefits of flexible PCB circuit boards

PCBA board is the finished product of PCB board which though SMT mounting , DIP plug-in and PCBA test, almost all electronic products need to use PCBA board.With the continuous development of electronic industry, the size of components is getting smaller and the density is getting larger.

Flexible pcb circuit board, also known as “soft board”, is a printed circuit made of flexible insulating substrate.Flexible circuits provide superior electrical performance to meet the design requirements for smaller and higher density installations and also help reduce assembly processes and enhance reliability.Flexible circuit board is the only solution to meet the requirement of miniaturization and movement of electronic products.

1.Types of flexible PCB

In the past, this interconnection technique was achieved by interconnecting wires.There are many types of flexible circuit boards:

（1）two-way access to the flexible circuit, this is a one-way flexible circuit, the purpose of manufacturing this circuit is to be able to access conductive materials from both sides of the flexible circuit .

（2）Double-sided flexible circuit is a circuit with two conductive layers, which are located on two sides of the basic layer of the circuit;According to your specific requirements, the two sides of the substrate sheet can be formed into a wiring pattern, the wiring on the two sides can be connected through the copper plated hole.

（3）Multi-layer flexible circuit is a combination of several single-side circuits or double-side circuits with complex interconnection. Shielding technology and surface mounting technology are often used in multi-layer design.

2.Rigid-flexible circuit is to integrate the advantages of rigid printed circuit board and flexible pcb circuit board. The circuit is usually connected through the electroplating through-hole between the rigid circuit and flexible circuit.

FASTPCBA is a enterprise specializing in PCB assembly.The company has strong technical strength, perfect testing means and the most direct supply channels.It’s an agent for many famous companies in the world.With the gradual expansion of the company’s scale, the business scope is further improved, involving PCB assembly, SMT mounting process and buying components and assemble PCB one-stop service.

3.The benefits of flexible PCB:Flexible circuits have many advantages.One of the main benefits of flexible components is the ability to achieve almost error-free wiring layout, replacing labor-intensive manual wiring.In addition, unlike rigid circuits, flexible circuits can be designed into complex three-dimensional structures because they can be bent into various shapes.As the name suggests, materials used in flexible circuits can be bent back and forth countless times, which means they can be used for highly repetitive applications, such as printing heads.When PCBA manufacturers need to consider the weight of their products, flexible circuits are an excellent alternative to rigid circuit boards and wires, because their dielectric materials and conductor lines are very thin.

With the development of science and technology, it is believed that flexible circuits will become smaller and more complex in the future, and the assembly cost will become higher and higher.Therefore, for PCB practitioners who want to stand in a higher position in the future need to constantly understand, learn and master more knowledge about flexible circuits.
