The hardware cost of electronic products is mainly composed of the costs of the circuit board, components, and PCB assembly, that is, the PCBA processing cost. The following is the cost calculation method for each part:

1. PCB cost: According to the process parameter requirements of the PCB, calculate the price per square meter, and then multiply it by the area of the PCB required for the product. For prototype orders, the engineering cost will be calculated separately, and a minimum consumption may also be set for the PCB manufacturing cost.

2. Component cost: Export the Bill of Materials (BOM) list from the schematic diagram, classify and count the quantity of components, and make a quotation based on the BOM.

3. SMD/DIP processing cost: Calculate the number of points according to the number of pins of the components. The unit prices of different pin types are different. After calculating the number of points, additional fees such as startup fees and stencil fees also need to be added.

4. Cost of tooling and testing fixtures: In batch orders, PCBA manufacturers may provide auxiliary tools such as wave soldering fixtures and testing racks, which are usually one-time fees.

5. Cost of special packaging and logistics: The special packaging materials are calculated according to the actual cost. If it involves the customs clearance and logistics fees for overseas customers, these fees also need to be included.

6. Other costs: If the customer has requirements such as functional testing of PCBA, assembly of the whole machine, and assembly of the casing, the cost of this part usually needs to be calculated according to the actual production time.

7. PCBA manufacturing cost calculation formula:

PCBA manufacturing cost = (① + ② + ③ + ④ + ⑤ + ⑥ + ⑦ + ⑧) * ⑨ * ⑩

Among them:

①: PCB board cost: All manufacturing costs of the printed circuit board.

②: Material cost: The materials here refer to the related materials required for PCB assembly, such as solder paste, stencil, and conformal coating (if required).

③: Component procurement cost: The actual cost of purchasing components.

④: Special packaging and logistics cost: The customer has special packaging requirements (such as specified box size, logo, etc.) and the estimated freight cost calculated according to the delivery address.

⑤: PCBA engineering cost: The cost of preparing production documents during PCB assembly. Generally, the engineering cost of PCBA prototypes is relatively high, and the engineering cost of batch orders is relatively low or even there is no such cost.

⑥: SMD/DIP soldering cost: Calculated according to the actual number of points to be assembled for SMD and DIP during PCB assembly.

⑦: Cost of PCB assembly tools and testing tools: The cost of manufacturing tools during PCB assembly (stencil, and if it is FPC or Rigid-Flex assembly, special molds need to be customized). The testing tools can be provided by the customer. If the customer provides the manufacturing documents of the testing tools, the PCBA factory will calculate the cost of the testing tools and manufacture them.

⑧: Other costs: If the customer requires the assembly of the whole machine, the assembly of the casing, the final functional testing of the PCBA, etc. Generally, the cost will be calculated according to the actual production time.

⑨: Order quantity: The actual number of orders that need to be produced.

⑩: Reasonable profit: The profit ratio of each company is different, which depends on factors such as the company's operating costs and scale.

In the field of electronic product manufacturing, the cost calculation of PCBA has always been a crucial and complex issue. Exactly how can one calculate a precise and reasonable cost? Relying on its profound professional foundation and years of practical experience, PCBMASTER has elaborated in detail the above-mentioned professional quotation methods for the prices of PCBA of electronic products, as well as the meticulous calculation methods for the prices of PCB assembly. This helps you clearly grasp the key points of cost accounting and gives you more advantages in production decision-making.
