Types of flexible circuit boards

Most PCBA manufacturers can produce flexible circuit boards, so what is a flexible circuit board? Flexible circuit boards, also known as "soft boards," are printed circuits made of flexible insulating substrates. Flexible circuit boards can provide high-quality electrical performance and meet the design needs of smaller and higher density installations, while also helping to reduce assembly processes and enhance reliability. So today, let's introduce the types of flexible circuit boards.



There are many types of flexible circuits:



1. A flexible circuit with bidirectional access, which is a single sided flexible circuit, is manufactured to allow conductive materials to be connected from both sides of the flexible circuit.



2. A double-sided flexible circuit is a circuit with two conductive layers, each located on the two sides of the basic layer in the circuit; According to your specific requirements, a wiring pattern can be formed on both sides of the substrate sheet, and the wiring on both sides can be connected to each other through copper plated through holes.



3. Multilayer flexible circuits are a combination of several complex interconnected single-sided or double-sided circuits, often requiring the use of shielding technology and surface mount technology in multi-layer design.



4. Rigid flexible circuits integrate the advantages of both rigid printed circuit boards and flexible circuits. Circuits are typically interconnected through plated through holes between rigid and flexible circuits.
