What are the classifications of PCB copy boards according to the type of substrate?

1. Flexible PCB board

The flexible board is a circuit board copy board made of a flexible substrate. Its advantage is that it can be bent, which is convenient for the assembly of electrical components. PCB has been widely used in aerospace, military, mobile communications, laptop computers, computer peripherals, PDA, digital cameras and other fields or products.

2. Rigid PCB board

The rigid circuit board is made of paper base (usually used for single side) or glass cloth base (usually used for double-sided and multi-layer), pre-impregnated phenolic or epoxy resin, and the surface layer is pasted with copper foil on one or both sides and then laminated and cured. made. This PCB copper clad sheet is called a rigid board. After making 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 strength. Its advantage is that it can provide certain support for the electronic components attached to it.

3. Rigid-flex circuit board

Rigid-flex circuit board refers to a printed circuit board containing one or more rigid areas and flexible areas, which are composed of rigid boards and flexible boards laminated together. The advantage of the rigid-flex board is that it can not only provide the support of a rigid printed board, but also have the bending characteristics of a flexible board, which can meet the needs of three-dimensional assembly.

The above is the PCB copy board introduced by Xiaobian for you to classify according to the type of substrate. I hope it will help you after reading.
