Type of flexible circuit board

Most PCBA manufacturers can make flexible circuit boards. What are flexible circuit boards? Flexible circuit boards can also be called "soft boards", which are printed circuits made of flexible insulating substrates. Flexible circuit boards can provide high electrical performance, meet the design requirements of smaller and higher density installations, and help reduce assembly processes and enhance reliability. Today, let's introduce the types of flexible circuit boards.

There are many kinds of flexible circuits:

1. The bidirectional access flexible circuit 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. The double-sided flexible circuit is a circuit with two conductive layers, which are respectively located on two sides of the basic layer in the circuit; According to your specific requirements, the wiring pattern can be formed on two sides of the substrate sheet, and the wiring on the two sides can be connected with each other through the copper plated through-hole.

3. Multilayer flexible circuit is a combination of several single-sided or double-sided circuits with complex interconnections. Shielding technology and surface mount technology are often used in multi-layer design.

4. Rigid flexible circuits integrate the advantages of rigid printed circuit boards and flexible circuits. Circuits are usually interconnected through electroplated vias between rigid and flexible circuits.
