PCB Technical - What are the risks of PCBA foundry materials?

The mode of PCBA OEM and OEM materials corresponds to the processing of incoming materials. The traditional method of PCBA processing is to hand over the PCB, materials, processing documents, etc. to the PCBA processing plant for processing, while the OEM method is All the processes that need to be processed are handed over to the electronic processing factory, and only the production documents and other materials are required. Below, Shenzhen PCBA foundry manufacturer Runze Wuzhou will briefly introduce you.

1. What is the foundry material

In a narrow sense, OEM materials refer to the processing companies that provide PCB, electronic component purchasing and PCBA processing services.

In a broad sense, OEM materials refer to one-stop PCBA processing services from electronic program design, product development, material purchasing, prototype proofing and testing, post-production batch processing, assembly and other one-stop PCBA processing services.

2. What are the types of foundry materials

1. Technical

The main capabilities are biased towards program research and development, forward or reverse research and development, product design, etc., while developing products, it can also provide corresponding PCBA processing and material procurement services.

2. Processing type

Processing companies generally have multiple SMT patch production lines and DIP plug-in post-welding lines, as well as complete testing equipment, three preventions, potting glue, etc.

The company has several SMT chip processing production lines, which can provide efficient electronic product processing services. However, fewer resources are provided for product development, and customers are generally required to provide relevant technical documents for processing.

Third, how to PCBA foundry manufacturers

You need to start with your own needs. If you have relevant PCB files, you only need the follow-up PCBA processing and production. Usually, you choose a processing-oriented factory that has a greater advantage in experience and price. If your own products need to be developed from scratch, choose a technology-oriented type. The factory is relatively better.

So what are the risks of the foundry 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.

4, capital risk

The PCBA foundry production model requires processing manufacturers to help customers purchase all materials. Customers need to pay an advance payment. Generally, 70% of the total payment is prepaid. Then the manufacturer starts to purchase materials and carries out the PCBA processing production process. Finally, when the product is shipped The customer pays the remaining 30%. As we all know, the value of PCBA OEM service is generally relatively high, and the transaction amount is relatively large. In the process of cooperation between the two parties, defaulting on the accounts will easily lead to the break of the company’s funds, thus increasing many uncontrollable risks.

In general, this is a good PCBA processing model, but it requires customers to find a PCBA foundry with many years of experience and strict quality control.
