1. Process preparation is time-consuming and laborious
Proofing is a very critical step in the production process. Its main purpose is to verify the feasibility of product design and the stability of the process. In order to ensure the quality of proofing, the factory needs to invest a lot of time and energy in preliminary preparation. Including making steel mesh, programming, first-piece inspection, debugging equipment, adjusting process parameters, etc., these are very time-consuming and complicated processes.
Compared with mass production, every process link in proofing needs to be carefully adjusted, and even multiple repeated verifications may be required to achieve the best results. And these time and labor costs are often difficult to spread to each product in a small number of proofing orders, so the unit price will naturally be higher.
2. High equipment adjustment cost
SMT patch processing requires the use of expensive and complex equipment, which needs to be precisely adjusted and set during the production process. For proofing, due to the low output, the time and frequency of equipment adjustment are higher than mass production. Especially when producing diversified and small batches of products, frequent equipment adjustments increase the complexity and cost of production.
For example, each different PCB board needs to adjust the equipment according to its unique design characteristics before processing. These adjustments are not just simple parameter settings, but may also involve physical adjustments of the equipment, such as changing lines and fixtures. These all require professional technicians to operate, which increases the time and labor costs of proofing.
3. Difficulty in purchasing materials and components
During the proofing stage, companies usually purchase a small amount of materials and components. The purpose of doing so is to reduce inventory risks and reduce capital occupation. However, due to the small purchase volume, suppliers cannot provide preferential prices for bulk purchases, resulting in high material costs. Especially for some special components, when purchased in small batches, the price may even be several times higher than that of large batches.
In addition, the purchase of a small amount of components may also encounter problems such as long supply cycles and unstable procurement channels, which further increases the cost of proofing.
4. High risks and uncertainties in the production process
During the proofing stage, product designs are often not fully mature, and design changes and process adjustments may occur. These uncertainties make the proofing production process riskier, and factories need to invest additional resources to deal with possible changes and re-production.
In order to ensure the quality of the final product, factories usually conduct more stringent quality control and testing during proofing, which also increases the frequency of use of testing equipment and labor costs.
5. The unique value of proofing
Although the unit price of proofing is high, its position in the entire production process is irreplaceable. Through proofing, customers can discover problems in product design and process in advance and avoid serious quality problems in mass production. This can not only improve the reliability of the product, but also lay a solid foundation for subsequent mass production.
In general, the unit price of SMT patch processing proofing is high because it involves complex preliminary preparations, equipment adjustments, material procurement and high-risk production processes. Although the unit price is high, the importance of proofing lies in that it provides quality assurance and process verification for mass production. Therefore, in the electronics manufacturing industry, the investment in the proofing stage is worthwhile, which helps to ensure the quality and market competitiveness of the final product.
