How to Calculate PCB Assembly Cost


PCB assembly cost is influenced by several factors. Customization and component sourcing are two main factors that increase the price. Customization can be beneficial but can also add up to a large expense. The good news is that there are ways to reduce the customization you require without compromising your budget.

The cost of labour is a key cost factor in PCB assembly. Depending on the region of manufacture, this cost can increase by up to 30%. The number of layers in a PCB also increases the cost. The more layers, the more materials will be used. This increases the cost of manufacturing.

Another factor to consider is the design specifications. Depending on the design specifications, a PCB can be made of multiple materials or just one. Choosing the right material and design for your PCB will impact the price. Simpler designs will typically cost less because they require less complicated production.

PCB assembly is a time-consuming process, and it's often based on a combination of components. It involves some steps, including testing procedures and high technology. Ultimately, the cost of PCB assembly will depend on the companies you choose and the products you plan to produce. PCB assembly is an important part of the manufacturing process, but it can also be difficult to determine the exact cost. Luckily, there are PCB assembly cost calculators available to help you calculate the price.


PCB assembly cost calculators are a useful tool for determining the overall cost of your project. The process includes many different steps and requires a comprehensive evaluation of your project. You will need to factor in the size of the board, the type of assembly, and the attached components, among other factors.

The PCB assembly cost depends on several factors, including labour cost, stencil cost, turnaround time, and the quantity of assembled boards. Other factors that determine PCB assembly costs include programming costs and packaging materials. Bittele doesn't charge extra for programming. These factors can add up to as much as 50% of your total PCB assembly cost.

The amount of copper layers in your PCB also affects the price. Thick copper layers cost more. Additionally, the more complex the design, the more expensive it will be. More intricate PCB designs require numerous connections and multiple layers. In addition, they often use up-down connection configurations.

The number of solder points on the PCB also affects the PCB assembly cost. When using surface mount technology, the cost of the PCB assembly process is lower than that of through-hole technology. The latter is more expensive because of the complexity of the lamination process. Generally, it is more economical to use surface mount technology because it is more automated and increases component density.

Turnaround time

When calculating the cost of PCB assembly, it is important to consider the turnaround time. Typically, a PCB assembly requires about three business days, but sometimes the turnaround time can be longer. However, in some cases, a shorter turnaround time can save you a lot of money. For instance, a three-day turnaround time for a large number of circuit boards in North America will only cost $1,100, whereas the same quantity of circuit boards in the People's Republic of China will cost $545. It is important to consider shipping, handling, and communication delays when determining a PCB assembly cost because cheap manufacturing often comes with hidden costs.

PCB manufacturers design PCBs to meet the specifications of different industries. Consequently, the cost of PCB assembly depends on the type of product and the assembly option used. For instance, surface mount technology may be less expensive than through-hole drilling, but it also means more labour costs. Also, some parts require more time to package. Electric equipment, for example, requires more time because it needs to be connected to the electrical circuit and undergo an X-ray examination.

As the number of PCBs increases, so does the cost of assembly. PCB manufacturers that have the ability to produce larger volumes can lower their costs. However, these factors only affect the first units, meaning that subsequent units can be produced without incurring the initial costs. Therefore, it is advisable to choose a manufacturer that can meet your volume requirements and meet your turnaround time.

Human waste

Waste in the production process refers to activities that do not add value. This includes inefficient equipment operation, idle or unbalanced production lines, improper use of solder paste, and PCB board damage or deterioration. The concept also extends to the costs associated with personnel, equipment, and lost working hours.

FR-4 laminate

FR-4 copper-clad laminate is a low-cost material that meets the needs of general electronic products, instrumentation, and peripheral computer products. The main advantage of FR-4 is its cost-performance ratio. It is also fire-resistant and has excellent mechanical strength and insulating capacity even in humid and dry environments.

FR4 comes in a variety of standard thicknesses, which makes it easy to calculate a PCB assembly cost. Often, the material used is the same for multiple customers, making it possible to purchase in volume at a lower price. In addition, many electronic assemblies use common laminates and cores, which can reduce costs.

The thickness of FR-4 also affects the overall weight of the final PCB. A thinner board uses less space, which means it is a good choice for smaller devices. However, thin FR-4 boards are not suitable for large devices. Thin FR-4 boards are not flexible and may cause damage to components.

Choosing the right laminate material is critical. Depending on your PCB design, you may want to choose high-performance FR4 laminate. This material offers improved thermal resistance, low expansion rates, and improved manufacturability.


If you're looking for a PCB manufacturer who can meet your needs, you can find one in Moko Technology. The circuit board assembly cost for this material is roughly 10% higher than that of standard FR-4. Using this material in a circuit board assembly project means that you can expect a high-performance PCB. The material used in FR-4 PCBs is fire-resistant, which makes it a good choice for most applications. However, if you're designing a board for an impressive temperature range, you may need a different material.

FR-4 is an epoxy resin that is flame-retardant. This material is commonly used for PCBs. It's also used for automotive circuits, industrial instrumentation, digital circuits, and military services. This material's resistance to heat and corrosion makes it a good choice for many applications.

FR4 has a Tg value that is high enough to withstand high temperatures without melting. Its Tg value, also called the "glass transition temperature," is 130 ℃. If your circuit board is designed to operate at a high temperature, a high Tg value may be the best choice.

Aluminium stiffeners

When calculating PCB assembly cost, consider the stiffener material used. The most commonly used stiffener material is polyimide. Other options include aluminium and stainless steel. The choice of stiffener material depends on the design and requirements. Polyimide is the least expensive option. Aluminium, on the other hand, is the most expensive but is also the most rigid. Moreover, aluminium is a popular choice for heat-dissipation applications.

The stiffener board is fixed to the PCB 42 at a first mounting interface 52 and to the vehicle structure 54 at a second mounting interface 56. The stiffener board 50 includes a main body portion 58. The body portion 58 is typically made of a rigid material. It may be manufactured by a casting process or a stamping process. It could also be manufactured with other known methods.

In order to calculate PCB assembly cost using aluminium stiffeners, use the following parameters. The overall thickness of the panel is important, as it will affect manufacturing costs. It is also important to consider the panel's surface area. A larger surface area means fewer PCBs to fabricate, which can cut costs.
