PCB Tech - What is electronic PCBA labor and materials?

Contracting of labor and materials is a broad concept. In the field of PCBA electronic processing, it means that suppliers provide full-process services from circuit board production, raw material procurement, processing, testing, and assembly to save customers time, cycle, inventory and other costs. . At present, this method is increasingly becoming the first choice of system integrators and product manufacturers.

One, the characteristics of PCBA packaging materials

PCBA contracting labor and materials effectively saves customers' time and cost, and transfers the entire manufacturing process control to professional and experienced suppliers, avoiding bargaining and purchasing time, inventory costs, and material inspection in the procurement of electronic materials such as IC, resistors, capacitors, diodes, etc. Time, personnel expenses, etc., effectively transfer risks to suppliers. Under normal circumstances, although the quotations for labor and materials are relatively high on the surface, it can actually effectively reduce the cost of the enterprise, offset the invisible cost of the enterprise, and allow the enterprise to concentrate on its own special areas, such as design, research and development, marketing, and after-sales service.

Second, the potential derivative risks of PCBA labor and materials

In the process of PCBA contract labor and materials service, the audit of suppliers is particularly important, which almost determines the success of the cooperation, the key to whether the cost and product turnover can achieve the expected goals. It is undeniable that the market is indeed full of merchants who obtain excess profits by sacrificing customer quality and stealing raw materials, but this is not sustainable development after all. Shenzhen Zhengjiaxiang Electronic Technology Co., Ltd. believes that such an approach is a bottom line that will never be touched for companies that are aspiring to grow and develop in the industry. Therefore, the most important thing for auditing suppliers is not to listen to what they say, but to feel what they do, to behave in the world, and to solve problems for customers. These aspects are more important than equipment, factory scale, certificates, etc.

Third, the process of PCBA electronics manufacturing contract labor and materials

When designing a product, a customer has an important evaluation: Design For Manufacturability (DFM), which is critical for the quality control of the manufacturing process, and rarely causes disputes with suppliers on the cause of problems. .

After the customer completes the product design, he submits the PCB file, BOM list and other engineering documents to the supplier. The supplier usually has a dedicated technician to review, confirm, and evaluate the stencil printing, patch process, plug-in process and other details. After that, the customer prepays the supplier for the construction of labor and materials (ranging from 80% to 30%, depending on the profit of the product, generally 70%). After the supplier receives the payment, the component purchases, and the materials are prepared according to PMC To plan production, for customers, it is the acceptance and payment of the balance.
