Why are more and more PCBs made into multilayer boards? This is a question that many friends are asking now. In fact, the editor of Shenzhen Ideas PCB Technology Limited tells everyone: When PCB circuit boards were first born, the application field was not large, and there were no multi-layer boards at that time. With the development of the times, due to high integrated circuit technology and microelectronics technology With the development of the development, the volume of electronic products is getting smaller and smaller, so the requirements for circuit substrates carrying various electronic components are getting higher and higher. Let Shenzhen Ideas PCB Technology Limited Xiaobian take you to understand the advantages of multi-layer boards today:
For the most basic PCB, components are concentrated on one side, and wires are concentrated on the other side. Because only one side can be wired, this PCB is also called a single panel, and both sides of a double panel can be wired, so the wiring area is larger than that of a single panel. The panel is doubled, suitable for use in more complex circuits.
For a simple circuit like a radio, it is usually enough to use single and double panels, but with the upgrading of electronic products, the complexity of the circuit is greatly increased, and higher requirements are placed on the electrical performance of the PCB. If single and double panels are still used, Then the volume will be large, and it will be very difficult for wiring, and the interference between lines will not be easy to deal with. So multi-layer boards came into being.
The assembly density of PCB multilayer board is high. Small size; the connection between electronic components is shortened, which speeds up the transmission speed; it is convenient for wiring; for high-frequency circuits, a ground layer is added to make the signal line form a constant low impedance to the ground, and the shielding effect is better.
At present, the common multi-layer boards are mostly four-layer boards or six-layer boards, but now there are more than 100-layer practical printed circuit boards.
