Advantages Of Multilayer PCB Boards

Nov. 11, 2019

PCB boards, also known as printed circuit boards, are the providers of electrical connections for electronic components. The main advantages of using a circuit board are greatly reduced wiring and assembly errors, increased automation levels and production labor rates.

Single panel: On a basic PCB, the parts are concentrated on one side and the wires are concentrated on the other side. Since the wire only appears on one side, this PCB is called a single panel. Because single-panel has many limitations on the design line (because there is only one side, the wiring can't cross and must follow a single path), so only early circuits use such boards.

Double panel: This board has wiring on both sides, but to use the two sides of the wire, you must have the appropriate circuit connection between the two sides. The "bridge" between such circuits is called a via. The via hole is a small hole filled or coated with metal on the PCB, which can be connected to the wires on both sides. Because the area of the double panel is twice as large as that of the single panel, the double panel solves the difficulty of wiring interleaving in a single panel (can pass through the via hole to the other side), and it is more suitable for circuits that are more complicated than a single panel. If you have a need for this, you can contact us, we can provide Double-sided PCB Wholesale.

Multilayer board: In order to increase the area that can be routed, the multi-layer board uses more single or double-sided wiring boards. Use a double-sided interior layer, two single-sided outer layer or two double-sided inner layer, two single-sided outer printed circuit boards, alternating by positioning system and insulating bonding materials and conductive patterns are interconnected according to design requirements The printed circuit board becomes a four-layer, six-layer printed circuit board, also known as a multilayer printed circuit board. The number of layers of the board does not mean that there are several layers of independent wiring layers. In special cases, empty layers are added to control the thickness of the board. Usually the number of layers is even and contains two layers on the outer side.

Most of the motherboards are 4 to 8 layers of structure, but technically they can achieve nearly 100 layers of PCB. Large supercomputers mostly use quite a few multi-layer motherboards, but because such computers can already be replaced by clusters of many common computers, super-multilayer boards have gradually disappeared. Because the layers in the PCB are tightly coupled, it is generally not easy to see the actual number, but if you look closely at the motherboard, you can still see it.

So here are our Multilayer Flexible PCB Manufacturer to talk about the advantages of multi-layer PCB boards.

The advantage of a multi-layer PCB board is that the lines can be distributed in multiple layers of wiring, allowing for the design of more sophisticated products. Or smaller products can be achieved with multi-layer boards. Such as: mobile phone circuit boards, micro projectors, voice recorders and other volumetric products. Additional layers allow for greater design flexibility, better control of differential impedance and single-ended impedance, and better output at some signal frequencies.

Multi-layer circuit boards are the inevitable result of the development of electronic technology to high speed, multi-function, large capacity and small volume. With the continuous development of electronic technology, especially the extensive and in-depth application of large-scale and ultra-large-scale integrated circuits, multi-layer printed circuits are rapidly moving toward high-density, high-precision, high-level digitalization, and there are fine lines and small apertures running through. Blind hole buried hole high plate thickness ratio and other technologies to meet the needs of the market.

Due to the high-speed circuit needs of the computer and aerospace industries. Further increasing the packing density, coupled with the reduction of the size of the discrete components and the rapid development of microelectronics, the electronic device is shrinking in size and the direction of quality reduction; single and double-sided printed boards are impossible due to the limited space available. A further improvement in assembly density is achieved. Therefore, it is necessary to consider using more printed circuits than double-layer layers. This creates conditions for the emergence of multilayer boards.

The above is about the advantages of multi-layer PCB circuit board, I hope to help everyone. In addition, if you are interested in PCB circuit board, you can contact us, we can provide you with PCB Board For Power Electronics Manufacture, the quality is reliable, the price is right, welcome you.
