PCB Technical - Precautions and model risks of PCBA foundry materials

Now the electronic processing industry has a one-stop processing service that is gradually becoming popular, that is, the PCBA OEM model. Customers who choose PCBA OEM materials only need to provide electronic processing companies with the complete processing required materials and then wait for the receipt of the goods, which is very convenient. Today, the editor will talk about "PCBA foundry material precautions and the risks of the foundry material model"

1. Precautions for PCBA foundry materials

1. In the process of selecting a PCBA OEM manufacturer, the customer must conduct a practical visit to its basic situation, especially the formality and professional ability of the manufacturer. Regarding its formality, we can learn from its corresponding qualification certificates, such as whether it is ISO9001 quality management system certification, etc.; it is necessary to be more careful to understand its professional capabilities in electronic product processing. I personally went to the PCBA manufacturer to visit and inspect the site. The main contents of the visit included the situation of the SMT patch processing production workshop,

the situation of the DIP production workshop, the office environment, and the spiritual outlook of the company's employees. Customers can also fully consider the development trajectory of the manufacturer in recent years. If the development is getting better, they can also judge the overall strength of the manufacturer from a certain level and whether it is suitable for mutual cooperation.

2. In order to better guarantee the product quality of PCB boards and electronic components supplied by PCBA foundry manufacturers, we must look at the well-known companies that cooperate with them in the process of selecting suitable processing manufacturers. Which ones? Find out if the company you are cooperating with is a well-known medium and large-scale enterprise, or if it provides a comprehensive supporting solution for PCBA for well-known brand companies; or analyze the electronic equipment business field of its production and processing. There is no current hot business area, so you can indirectly understand its production and processing capabilities. In addition, it is necessary to visit and investigate whether the manufacturer has established good quality management and comprehensive procurement strength advantages in electronic component matching, and whether the long-term and stable cooperative relationship between the manufacturer and the agent has a good delivery time and supply cost. Advantages and so on.

2. What are the risks of the OEM model?

1. It is difficult to confirm the authenticity of materials

As PCBA foundry manufacturers are responsible for the overall manufacture of electronic components and PCBs, some electronic processing plants pursuing profit may purchase some counterfeit and shoddy materials in order to reduce production costs. In this case, the quality of the material can be ensured by specifying the material supplier and providing the original certificate of the material.

2. The procurement cycle is unstable

In the entire production cycle of PCBA processing, material procurement is the most unstable, especially when the components used by the customer are scarce, not common supplies, or the demand for components is large, and the foundry has no inventory and needs to take the way of ordering At this time, uncontrollable factors will occur.

3. Difficulty in maintenance

If the PCBA foundry manufacturer does not have strong repair capabilities, it will cause difficulty in product repair and prolong the repair cycle, which will eventually affect the delivery time of the product and cause relatively large losses to the customer
