What Types Of Flexible Circuit Boards Can Be Divided Into?

Most PCBA manufacturers can make flexible circuit boards, so what is a flexible circuit board? Flexible circuit boards can also be called "soft boards", which are printed circuits made of flexible insulating substrates. Flexible circuit boards can provide high-quality electrical performance, and can also meet the design needs of smaller and higher-density mounting, while at the same time helping to reduce assembly processes and enhance reliability. So today, we will introduce the types of flexible circuit boards.

There are many types of flexible circuits:

1. Two-way access flexible circuit. This is a single-sided flexible circuit. The purpose of manufacturing this circuit is to access conductive materials from both sides of the flexible circuit.

2. Double-sided flexible circuit is a circuit with two conductive layers. The two conductive layers are located on the two sides of the basic layer in the circuit; according to your specific requirements, it can be formed on the two sides of the substrate sheet. Line pattern, the traces on the two sides can be connected to each other through copper-plated through holes.

3. Multi-layer flexible circuit is a combination of several single-sided circuits or double-sided circuits with complex interconnections. In the multi-layer design, shielding technology and surface mount technology are often used.

4. Rigid-flex circuit integrates the advantages of both rigid printed circuit boards and flexible circuits. The circuits are usually interconnected through plated through holes between the rigid circuit and the flexible circuit.
