Multilayer PCBs Versus Double-sided PCBs

The Key to High-Performance: Double-sided PCBs to Multi-layer PCBs

Multilayer PCBs Versus Double-sided PCBs

Multilayer PCBs are a kind of printed circuit board composed of alternating conductive graphic layers and insulating material laminated. The number of conductance pattern layers is more than three layers, and the electrical interconnection is realized through metallization holes. If double-sided PCBs are used as the inner layer, two single panels as the outer layer, or two double panels as the inner layer, two single panels as the outer layer, and interconnect with conductive graphics, it can be made of four layers, six layers of printed circuit boards, also known as multi-layer circuit boards.

The production process is to blacken the inner plate pattern first, add the semi-cured layer according to the predetermined design for lamination, then add a piece of copper foil on the upper and lower surfaces, send the press to heat and pressure, to obtain the “double-sided copper clad plate” that has been made of the inner plate, and then carry out CNC drilling according to the pre-designed positioning system. After drilling, the hole wall should be dented and contaminated, and then treated according to the process of double-sided printed circuit board manufacturing.

Compared to the two-panel production process, the main difference between multilayer panels is the addition of several unique process steps: inner imaging and blackening, lamination, dimpling and de-drilling contamination. The same processing process, in terms of process parameters, equipment accuracy, and complexity, there are also some differences. For example, the quality requirements of multi-layer plate hole wall are higher, and the quality requirements of double-layer plate hole wall are higher. In addition, the number of layers drilled in each multi-layer board, the speed and feed rate of drilling, and the difference between the double-sided PCB board. The inspection of finished products and semi-finished products is also more stringent and complex than the inspection of double panels.

Multilayer PCB boards are the addition of an inner layer board on the basis of double panels, usually 4 layers, 6 layers, 8 layers, or more layers. The double panel has only two layers of copper foil, one layer for wiring and the other layer for welding components.

Multi-layer panels have a higher wiring density than dual panels because they can be routed at multiple levels, thus reducing wiring crossover and interference. This makes multilayer PCBs suitable for complex circuit designs and high-density electronic devices.

The multiple-layer PCB board has good electromagnetic compatibility and anti-interference ability because the inner layer board can play a shielding and isolation role. The dual panel is relatively weak in this respect because there are only dual layers of copper foil.

Multilayer boards are more complex and costly than double-sided boards. The manufacture of multilayer panels requires more processes and materials, so its manufacturing costs are higher. At the same time, the design and wiring of multi-layer boards are also more complex, requiring higher technical requirements.

Multilayer circuit board has more advantages in signal transmission and power consumption control. Since the multilayer board can transmit signals and distribute power through the inner layer board, the transmission delay and power consumption of the signal can be better controlled.

In general, multilayer PCBs are more suitable for complex circuit design and high-density electronic devices than dual panels, but their manufacturing costs and design difficulties are correspondingly higher.

Due to the increasingly high functional requirements of electronic products, the structure of PCB boards is becoming more and more complex, from single layer to double layer and then to multiple layers, gradually “evolving”.

multilayer PCBs fabrication

Unveiling the Cutting-Edge Technology of multilayer PCBs!

PCB boards, also known as printed circuit boards, are the carriers of electronic components and an essential element of circuits. They consist of substrates, conductive layers, printing layers, drilled holes, solder pads, and so on. The number of layers in a PCB board is an important factor that manufacturers and designers need to consider in the design and production process. In modern electronic products, multilayer PCBs are widely used.

multilayer PCBs fabrication

How many layers can a PCB board have?

Firstly, it is important to understand that the number of layers in a PCB board refers to the number of conductive layers in the board, excluding non-conductive layers such as mechanical support, signal layers, and power layers. Commonly available PCB board layers include single-layer, double-layer, four-layer, six-layer, eight-layer, ten-layer, twelve-layer, etc. Generally, the more layers a PCB board has, the greater the manufacturing difficulty and cost. Therefore, the selection of a PCB board should be based on actual needs.

However, for special applications that require higher layer counts, such as integrating more electronic components on the same board or requiring higher signal transmission speed and lower signal interference, a multi-layer PCB board can be chosen. It is known that the highest number of layers for PCB boards available in the market can reach 60 layers or even more. However, manufacturing such PCB boards is highly challenging and costly, and they are typically used for special high-end applications.

In conclusion, the number of layers in a PCB board is determined by actual needs. In most cases, selecting a four-layer or six-layer PCB board is sufficient for the majority of applications. If a higher number of layers is required, factors such as manufacturing difficulty and cost need to be considered. Therefore, when choosing a PCB board, it is important to consider various factors and select the one that best suits the application’s needs.

On a theoretical level, multi-layer PCB boards can have any number of layers as long as the manufacturing equipment is capable. However, in practice, the most common PCB boards range from 4 to 10 layers, with special military or specific-purpose PCBs reaching over 100 layers. Nevertheless, these multilayer PCBs are not suitable for mass production.

Multilayer PCBs History

In 1961, Hazeltine Corp. from the United States introduced Multiplanar, which was the pioneer in multi-layer board development. This method is similar to the current manufacturing process of multi-layer boards using plated through holes. Since Japan entered this field in 1963, various conceptual designs and manufacturing methods for multi-layer boards have gradually become popular worldwide. As the transition from transistors to integrated circuits occurred and computer applications became more widespread, the demand for high functionality led to the focus on high wiring capacity and transmission characteristics in multi-layer boards.

Initially, three manufacturing methods for multi-layer boards, namely the gap method, the lamination method, and the plated through hole (PTH) method were introduced. The gap method was not practical due to its time-consuming manufacturing process and limited high-density capabilities. The lamination method, although offering high density, was complex and not as urgently needed at that time. However, as the demand for high-density circuit boards grew, the lamination method became a focal point for research and development by various manufacturers. Currently, the PTH method, which shares the same process as double-sided boards, remains the mainstream manufacturing method for multi-layer boards.
