PCBA Tech - How is the cost of PCBA calculated?

When designing electronic products, we not only need to consider the product's functionality but also frequently evaluate costs, because if the cost of a product is too high, it will be difficult to maintain profitability and competitiveness. So electronic engineers will fully consider the hardware cost of electronic products when designing products.

So what makes up the hardware cost of an electronic product? How to calculate the cost of PCBA processing for electronic products?

The hardware of electronic products mainly consists of the prices of circuit boards, components, and SMT processing, which is the cost of PCBA processing.

PCBA manufacturing

Below, we will provide a detailed explanation of the price calculation for these three parts:

1. The price of a PCB circuit board is calculated based on the process parameter requirements of the PCB, and then the price per square meter of the PCB is calculated, and the amount of square meter of PCB required for the product is calculated.

2. The price of components, first open the schematic, export the corresponding BOM, classify the same components into one category, and count the number of components in each category. Then, based on the BOM, calculate the quantity of various components for quotation.

3. The prices of SMT and DIP are calculated based on the number of points. Therefore, the pins of the device are first counted, and the unit price of different types of pins is different. After the number of points is calculated, the startup fee, steel mesh fee, etc. need to be added.

4. The cost of tooling and testing fixtures. For bulk orders, PCBA manufacturers may provide production auxiliary tooling such as wave soldering fixtures and testing racks, which are usually a one-time fee.

5. Special packaging and logistics costs. In terms of packaging logistics, special packaging materials need to be accounted for at cost. If foreign customers have separate customs declaration logistics costs, this part of the cost also needs to be calculated.

6. The calculation formula for PCBA manufacturing cost

The following is a simple formula for calculating the manufacturing cost of PCBA, for your reference. For more details, please get in touch with iPCB customer service.

The price of PCBA manufacturing = (A+B+C+D+E+F) * G * H+J+K, where:

A = PCB board cost expense

B = Material cost

C = PCB testing cost

D = PCB engineering cost

E = Component procurement cost

F = Special packaging and logistics costs

G = quantity of sample products

H = Reasonable profit

J = PCBA engineering cost

K = SMT/DIP welding cost
