According to substrate classification: flexible circuit board, rigid circuit board, and rigid flexible combination board.

1. Flexible PCB board (flexible board)

Flexible board is a printed circuit board made of flexible substrate, which has the advantage of being flexible and easy to assemble electrical components. FPC is used in aerospace, military, mobile communications, laptops, computer peripherals PDA、 Digital cameras and other fields or products have been widely used.

2. Rigid PCB board

It is made of paper-based (commonly used for single-sided) or glass cloth based (commonly used for double-sided and multi-layer), pre impregnated with phenolic or epoxy resin, and then laminated and cured with copper foil on one or both sides of the surface. We call this type of PCB copper-clad board a rigid board. When remanufactured into a PCB, we call it a rigid PCB. A rigid board is a printed circuit board made of a rigid substrate that is not easy to bend and has a certain degree of toughness. Its advantage is that it can provide certain support for the electronic components attached to it.

3. Rigid flex PCB board (rigid flex PCB board)

A rigid flexible combination board refers to a printed circuit board that includes one or more rigid and flexible regions, composed of rigid and flexible boards laminated together. The advantage of the rigid flexible combination board is that it can provide support for rigid printed boards and also has the bending characteristics of flexible boards, which can meet the needs of three-dimensional assembly.
