Why is the price of PCBA small batch proofing high?

The main factors affecting the cost of PCBA proofing processing

PCBA proofing means that before large-scale production, manufacturers usually make a small batch of PCBA board samples. These samples are usually made according to the customer's design requirements and specifications, and are assembled and tested through a series of process flows. The purpose of PCBA proofing is to verify the feasibility of product design, the rationality of production process and the stability of product performance.

The main factors affecting the cost of PCBA proofing processing:

High cost of small batch production:

PCBA proofing is usually for small batch production needs. Compared with large-scale batch production, the unit cost of small batch production is usually higher. Because in small batch production, fixed costs (such as equipment depreciation, labor costs, etc.) cannot be allocated to a large number of products, resulting in an increase in the production cost of unit products.

Process debugging cost:

In the PCBA proofing stage, the production process needs to be debugged and optimized to ensure the quality and stability of production. This may involve multiple trials and adjustments, which consumes manpower and time, thereby increasing production costs.

Raw material cost: 

For small batch production, the procurement cost of raw materials is usually higher, because suppliers may not be willing to offer discounts or preferential prices for small batch production.

Labor costs: 

The PCBA proofing stage may require professional technicians to perform manual operations, process debugging and other work, and these labor costs will directly increase production costs.

Low equipment utilization:

In small batch production, equipment utilization is usually low, because the equipment has a long downtime when debugging and changing products, and the downtime cannot be converted into production output value, thus affecting the production cost of the unit product.

The high cost of PCBA proofing processing is mainly due to the combined influence of factors such as small batch production, process debugging, raw material costs, labor costs and low equipment utilization. To reduce the cost of PCBA proofing, you can improve it by improving production efficiency, optimizing process flow, or increasing batch production scale.
