What Makes a PCB Expensive

The cost of a PCB is determined by many factors, including the type of board, its dimensions and number of layers. It also depends on the materials used and the manufacturer’s production standards.

Size and Shape: Depending on the size and shape of the board, the price can increase. If the board is larger, then it requires more materials and more time to manufacture.

If the board is smaller, it can be made with fewer materials and less labor, which will help to reduce costs. The size and shape of the board can be determined by the circuit itself, and a larger board may be needed for a more complicated circuit design.

The thickness of the board is another determining factor in how much it costs to produce. A thicker board with multiple layers will require more material and more work to construct. This will be true even if the board has narrow measurements and a relatively small aspect ratio.

Using Thin Copper Foils: A thin copper board is more efficient at using materials because it doesn’t have to use as much prepreg in the processing steps, and it doesn’t need as many copper foils. However, thin copper boards have the disadvantage of requiring more material to fill the gaps between copper foils, which will add to the manufacturing process.

Vias: Vias are holes that run through the layers of multi-layer boards to provide interconnectivity between them. These holes are usually not filled entirely, and the copper plating and finish will be visible in the holes. This will add about 10% to the board’s cost.

Compliance with Certification and Standards: PCBs must be manufactured to certain production and quality standards in order to ensure that they meet all safety and regulatory requirements. Printed circuit board manufacturers must use the highest-quality raw materials and the best production standards to guarantee that they can meet these requirements, which can add to their costs.

A high-quality PCB is an important part of any electronics product, and if it doesn’t meet the necessary standards, the manufacturer might face fines or other legal penalties. Consequently, manufacturers must ensure that their processes are as precise and high-quality as possible to avoid these penalties and protect their reputations.

Special Features: If the circuit on your PCB has a specialized feature or is designed with specific functionality in mind, then it will require a high degree of skill and expertise to produce. This will result in a higher cost, since the PCB manufacturer must hire more people to perform a specific set of tasks, and it will take more time to complete the entire production.

Packaging: The packaging of a printed circuit board is an important component to the overall product’s value. If the packaging is not appropriate, it could lead to damage and a lower overall product value.

Hole Size and Count: The size of the holes on your board can affect its price, too. A smaller hole size, such as 0.015’’, will increase the cost of your PCB by about 5%. Larger holes will also cost more, as they require a greater number of drills to create the holes and will increase the amount of time required for drilling.
