Double Sided PCB Manufacturer: What to Look for in a Reliable Supplier

Double-sided PCBs are an essential component of modern electronic devices. They are used in a wide range of applications, including computers, smartphones, and automotive systems. These PCBs are designed to provide increased functionality and reliability, as they allow for the placement of more components on a single board.

To meet the growing demand for double-sided PCBs, manufacturers have been investing heavily in research and development. They are constantly exploring new materials, design techniques, and manufacturing processes to improve the performance and efficiency of these boards. As a result, modern double-sided PCBs are more reliable, durable, and cost-effective than ever before.

If you’re looking for a reliable double-sided PCB manufacturer, there are several factors to consider. Look for a company that has a proven track record of delivering high-quality products on time and within budget. Make sure they have the necessary expertise, equipment, and resources to handle your specific requirements. By choosing the right manufacturer, you can ensure that your double-sided PCBs will meet your needs and exceed your expectations.

What is a Double Sided PCB?

A double sided PCB, also known as a double layer PCB, is a printed circuit board with conductive copper layers on both sides. The layers are connected by through-hole plating or by vias, which are small holes drilled through the board to allow the electrical connection between the layers. Double sided PCBs are commonly used in electronic devices that require more complex circuitry than single sided PCBs can provide.

Construction of Double Sided PCBs

The construction of a double sided PCB involves several steps. First, a substrate material, such as fiberglass or plastic, is coated with a layer of copper foil. This layer is then etched to create the desired circuit pattern. The board is then drilled to create holes for through-hole plating or vias. The holes are coated with a conductive material, such as copper, to connect the layers. Finally, a solder mask and silkscreen layer are applied to protect the board and provide labeling.

Advantages of Double Sided PCBs

Double sided PCBs offer several advantages over single sided PCBs. They allow for more complex circuit designs, as the additional layer provides more space for components and routing. They also reduce the size of the board, as components can be placed on both sides. This is particularly useful in compact devices, such as smartphones and tablets. Double sided PCBs also provide better signal integrity, as the additional layer can be used for ground planes or power planes to reduce noise and interference.

In summary, double sided PCBs are a versatile and widely used type of printed circuit board. Their construction involves multiple layers of conductive copper and substrate material, connected by through-hole plating or vias. They offer several advantages over single sided PCBs, including more complex circuit designs, reduced board size, and improved signal integrity.

Choosing a Double Sided PCB Manufacturer

When it comes to choosing a double sided PCB manufacturer, there are several factors to consider.

Material Type

The type of material used in the PCB also affects the manufacturing cost. For example, FR-4 is a commonly used material for PCBs, but it is more expensive than other materials like polyimide.


The quantity of PCBs being manufactured is another key factor that influences the cost. The more PCBs that are produced, the lower the cost per unit will be.

Manufacturing Process

The manufacturing process used to produce double sided PCBs also affects the cost. For example, using a more advanced process like surface mount technology (SMT) can increase the cost of manufacturing.

In general, the cost of manufacturing double sided PCBs can range from a few cents to several dollars per unit, depending on the factors mentioned above. It’s important to work with a reputable manufacturer that can provide a cost-effective solution without compromising on quality.


In conclusion, choosing the right double sided PCB manufacturer is crucial for the success of your project. By considering factors such as quality, cost, lead time, and customer support, you can ensure that you get the best value for your investment.
