FR4 Multilayer PCBs
Quality and quick-turn multilayer PCBs at low-cost prices.
Low-Cost and Quick-Turn Multilayer PCBs
While PCBs for simple applications typically consist of one layer, advanced applications such as computer motherboards have multiple layers. These types of boards are commonly known as multilayer PCBs. With the demanding complexity of modern equipment, multilayer boards have become more popular, while production techniques have allowed them to size down effectively.

We have more than ten years of experience in designing and manufacturing high-quality multilayer PCBs. We have state-of-the-art PCB fabrication equipment to ensure our end products meet customer requirements and industry standards.
By placing a double-layered board’s capacity into a format that is a fraction of the size, multilayer PCBs have become gradually common in the electronic industry. These boards come in various sizes and thicknesses to meet the requirements of their growing applications. Some variants range from three to twelve layers.
Benefits of Multilayer PCBs
Technically speaking, multilayer PCBs present multiple design benefits. Some of these benefits include:
Because of the intensive labor and planning that multilayer designs require, they tend to be better in quality than their counterparts. In addition, they are more reliable.
One of the significant advantages of multilayer PCBs lies in their small dimensions. Due to their layered format, multilayer boards are essentially more diminutive than their counterparts with similar functionality. This is beneficial to modern electronic devices, as there is a rising demand for miniaturized, more compact, and powerful electronics such as smartphones, personal computers, and wearables.
Smaller boards are lighter since the numerous connectors needed to interlink separate single and double-layered boards are removed from the equation by multilayered designs.
Naturally, multilayer PCBs are more durable than single and double-layered PCBs. They can withstand their weight and the heat and pressure applied in binding them. Besides, multilayer PCBs have several insulation layers between circuit layers.
While this feature does not apply to every multilayer board, some apply flexible design techniques. This gives rise to flexible multilayer boards, which are perfect for use cases where mild bending and flexing take place on a semi-regular basis. Again, this principle does not work for all multilayer boards, and the more layers integrated into a flexible board, the less flexible it becomes.
Multilayer boards are high-compact designs, integrating several layers into one board. The close-quarters allow the PCBs to connect better, and their internal electrical features enable them to obtain higher capacitance and speed.
Multilayer boards are meant to function as one unit rather than in tandem with other board components. Consequently, they contain one connection point instead of several connection points needed to use many single-layer PCBs. This is beneficial to electronics as they only require one connection point to function.
Applications of Multilayer PCBs
Multilayer printed circuit boards have become the go-to solution for various applications in almost every sector. This high demand has resulted from the steady push for mobility and functionality in the electronic world. Multilayer PCBs are the ideal solutions for this push, offering increased functionality and miniaturized sizes. Because of this, they have become almost pervasive in many technologies like:
