What is a multilayer PCB circuit board?

A multilayer PCB circuit board is a circuit board composed of multiple layers of circuit boards, which can stack multiple circuit board layers together to meet the complexity of circuit design. It can increase the density of the circuit board and reduce its size and weight of the circuit board. The types of multilayer PCB circuit boards include single-sided PCB circuit boards, double-sided PCB circuit boards, multilayer PCB circuit boards, and high-density multilayer PCB circuit boards. The single-sided PCB circuit board has only one layer circuit board, and its structure is simple, but its density is low, which cannot meet the requirements of complex circuit design. The double-sided PCB circuit board has 2 layers of circuit boards, which can increase the density of the circuit board, but still cannot meet the complex circuit design requirements. Multilayer PCB circuit boards have 4 or more layers of circuit boards, which can meet complex circuit design requirements, but their manufacturing costs are relatively high. High-density multilayer PCB circuit boards can increase the density of multilayer PCB circuit boards to the extreme.

Types of PCB circuit boards

A multi-layer PCB circuit board refers to a circuit board with multi-layer boards, of which there are at least 4 layers and up to 6 or 7 layers. They are separated by insulating layers, each layer has its own circuit, and can be connected to each other. The types of PCB circuit boards are mainly divided into single-layer PCB, double-layer PCB, multi-layer PCB, and special PCB. Single-layer PCB is the most common circuit board, it has only one layer of board material, which can be used for simple circuit design. A double-layer PCB has two layers of boards and can be used for complex circuit designs. Multilayer PCBs can have 4 or more layers of boards, and they can be used for more complex circuit designs. Special PCBs refer to circuit boards with special functions, such as high-frequency PCBs, anti-static PCBs, etc.

Application of multilayer PCB circuit board

A PCB circuit board is an electronic component consisting of one or more layers of insulating substrates and circuits. Multi-layer PCB circuit board is a special PCB circuit board, which is composed of multi-layer substrates and circuits, which can provide more functions. The types of multilayer PCB circuit boards include multilayer printed circuit boards, multilayer patch circuit boards, multilayer copper foil circuit boards, and special ultra-thick copper multilayer PCB. Applications of multilayer PCB circuit boards include automotive electronics, avionics, consumer electronics, medical devices, etc.
