PCB four-layer board and two-layer board advantages

With the rapid development of the PCB industry, the traditional double-sided board has not been able to meet the needs of most products, PCB layer tends to be more and more high development, four-layer board is also more and more by the design engineers like.2 oz copper thickness in mm So, what are the advantages of pcb four-layer board and two-layer board?

1. line design decision to choose: four-layer board or two-layer board depends on your line design. If the line is not very dense, you can use two layers to get it done, two-layer board is simple and intuitive. And four-layer board line is dense, TOP layer is also known as the front counts the top layer, the bottom layer is also known as the back. The four-layer board in the middle of the board line layer including gnd ground layer and sin through-hole alignment layer.

2. Production process and cost: four-layer board production process is more complex than two layers, the cost is also much higher, two-layer board price will be relatively low. The advantage of multi-layer PCB circuit board is that the line can be distributed in multiple layers inside the wiring, so that the design of more sophisticated products. Or smaller products can use multilayer board to achieve. For example: cell phone circuit boards, mini projectors, audio recorders and other products with a smaller volume. In addition, multilayer can increase the flexibility of the design, better control of differential impedance and single-ended impedance, as well as some of the signal frequency better output.

While single-layer circuit boards have their advantages, multilayer designs are more favorable for some applications. To know the advantages of multilayer PCBs, you need to know what a multilayer PCB is, and you can provide a click on what is a PCB multilayer board and what are the characteristics of a multilayer PCB to understand. For certain devices, it will be necessary to use multilayer PCB boards to fulfill the requirements. What exactly are the benefits of more complex multilayer PCBs?

1. Useful for more complex projects: equipment that is more complex and involves more circuits and components often requires the use of multi-layer PCBs. if it requires more circuits than can fit on a single board, space can be added by adding layers.plated through hole vs via Having multiple boards ensures that there is enough room for connections, making it ideal for more advanced devices. Devices with many different uses and advanced features (such as smartphones) require this level of complexity.

2. High quality: Multilayer circuit boards require more planning and an intensive production process, so they are often of higher quality than other types of boards. Designing and producing these boards requires more skill and more advanced tools than simple components, increasing the likelihood of a high quality product. Many of these designs include advanced controlled impedance characteristics and EMI shielding, further improving performance.

3. Increased power: Due to the increased circuit density of multilayer PCBs, they are more powerful than less complex designs. They have a higher operating capacity and can run at higher speeds, which is often necessary for the advanced equipment they power, and can improve performance.

4. Improved durability: Having more layers means that the board is thicker and therefore more durable than a single-sided PCB. This is another reason why adding functionality through additional layers is preferable to increasing the size of individual layers. This enhanced durability means that the board can withstand harsher conditions and generally last longer.

5. Smaller Size and Lighter Weight: Multilayer PCBs achieve this enhanced durability while still remaining relatively small in size and light in weight. Because they will be layered together, you can compress more functionality into a more compact space than with other boards. This smaller size also means lighter weight. Single-layer boards must be very large to match the functionality of multilayer boards. You can even use more than one monolayer to match it, but this also adds to the size and weight of the final product.

6. Individual connection points: Using multiple PCB assemblies requires multiple connection points. On the other hand, multilayer boards are designed to work with a single connection point, simplifying the design of electronic devices and further reducing weight. Multilayer PCB boards are often the best choice when deciding whether to use multiple single panels rather than just one multilayer printed circuit board.
