Comprehensive Understanding Of Multi Layers PCB

The definition of a multi-layer PCB is a PCB made of three or more layers of conductive copper foil. It’s equivalent to the upgraded version of single-sided PCB.


What is Multi-Layer PCB?

In the case of a large number of interconnection and crossover requirements, if the PCB circuit board wants to achieve a satisfactory performance, it must expand the board layer to more than 2 layers. Therefore, the original intention of the multi-layer PCB has appeared. It provides more freedom for the routing path.
The multi-layer circuit board contains three or more copper conductive layers, and usually with plated through holes. The copper layer is bonded together by a resin layer (Prepreg,PP). The manufacturing process is more complicated.

What Are The Advantages Of Multi-Layer PCBs?

Suitable for More Complicated Projects:  Projects that are more complex and involve more circuits and components often require the use of the multi-layer PCB. Because the single-layer board does not have enough space to realize complex circuit design, so people can add space by adding layers. Having multi-layer boards ensures there is enough space for connections, making it ideal for more advanced devices.

Higher Quality: The design and production of multi-layer circuit boards require more professional production knowledge and more advanced production lines, which increases your possibility of obtaining high-quality products. Many of the multi-layer PCB designs include advanced controlled impedance characteristics and electromagnetic interference shielding to further improve performance.

Increase the durability of PCB: The more layers, the thicker the circuit board, so it is more durable than single-sided or double-sided PCB. This increased durability means that circuit boards can withstand harsher conditions and generally have a longer lifespan.

Smaller size and lighter weight: Multi-layer PCBs achieve this enhanced durability while still maintaining a relatively small size and low weight. Because they stack layers together, you can compress more functions into a more compact space compared to other circuit boards. This smaller size also means lighter weight. The single-layer board must be very large to match the function of the multilayer board.

What Are The Applications Of Multi-Layer PCBs?

Medical equipment: Electronic devices are an indispensable part of the medical industry. Like any other industry that relies on electronics, the medical industry is also adopting miniaturization. With the popularization of non-invasive treatment technologies, the medical industry has an increasing demand for micro-devices. Multilayer printed circuit boards can perfectly meet the needs of these devices due to their small size, lightweight design and other powerful features. Some of the best examples of medical devices using multilayer PCs include X-ray equipment, CAT scanning equipment, blood pressure and blood sugar testing equipment, MRI, CT scanning, infrared temperature monitoring, etc.

Consumer electronic products: Consumer electronics, usually called household electronics, cover a wide range of electronic devices for daily use. This often includes devices used for communication, such as smart phones, laptops, etc.; entertainment, including smart TVs, music players; and kitchen appliances-microwave ovens, washing machines, etc. Most of these devices are equipped with multilayer printed circuit boards instead of standard single-layer PCBs. why? This is because the multi-layer PCB contributes to its functionality and compact design.

Industrial electronics: Electronic equipment used in an industrial environment is very different from consumer electronics. The reason is that they are exposed to harsh environments such as high temperature, shock, vibration, pressure, dust and humidity. Some common examples of industrial electronic equipment include automated assembly lines, packaging conveyors, painting robots, etc. They are designed for long-term operation and can work throughout the day. In this case, a durable PCB is required, and a multilayer PCB meets this requirement. Multilayer PCBs are more durable than other alternatives on the market today.

Computers and equipment: Today, we cannot imagine life without computers and automation. Due to its space-saving and functional features, all products of computers and related products (such as graphics cards, motherboards, computer mice, etc.) use multilayer PCBs. These PCBs can be designed to achieve superior performance at a lower cost than other competing technologies.

Telecommunications Electronics: Multilayer PCBs are used in many telecommunications equipment, such as GPS and satellite applications, and signal transmission. These equipment require durability while maintaining a high level of functionality. With the development of wireless technology, the demand for high-performance and precise micro-devices is increasing. Multi-layer PCB can easily meet the requirements. Other applications of telecommunications electronics include communication towers, radar electronics, power amplifiers, attenuators, and so on.

Military, aerospace, and Defense: Similar to the above industries, multilayer PCBs are becoming a priority for many military and defense applications. These PCBs have compact design, low weight, functionality and durability, and are high-speed devices. Unmanned ground vehicles (UGV), aircraft defense systems and avionics, unmanned aerial vehicles (UAV), surveillance, automatic guns, and radar systems are some of the devices equipped with multilayer PCBs. In order to meet the strict requirements of high circuits, multi-layer PCBs are assembled with military specification components to withstand the harsh environment where high temperature and high pressure may cause damage to grade components.
