PCBA Tech - Advantages and BOM Importance of PCBA OEM

With the development of electronic processing technology and electronic technology, the overall demand for PCB is growing. Many of them used to only provide PCBA processing with supplied materials, but now they provide one-stop service of PCBA OEM. What are the advantages of PCBA OEM?

1. Customers choose PCBA to substitute materials, which has great advantages in reducing the cost of purchasing materials. Because PCBA manufacturers can receive orders from all over the country, with a large number of customers, and the corresponding components are purchased in large quantities, they have stable component suppliers who have cooperated for many years, and can obtain the lowest purchase price.

2. Reduce labor costs. If you purchase materials yourself, you should have your own purchasing personnel, including PCB buyers and component buyers. These are not small expenses.

3. Reduce the storage expenses of the company. The storage of components requires certain conditions, such as a warehouse with constant temperature and humidity; It also needs to be managed by a specially assigned person, as well as the rental expenses of the warehouse, and the allocation of related equipment. These are all costs.

4. Avoid high expenditure on equipment. The whole process of PCBA processing requires SMT mounter, reflow soldering, wave soldering, selective wave soldering and other precision processing equipment and various testing equipment. One production line is almost 2 million yuan after configuration. In addition, idle equipment and capital are under pressure.

Therefore, customers choose PCBA OEM and material replacement, which has many advantages whether it is for large customers or small customers.

In daily work, many PCBA processing customers will ask, do you have a BOM? Why is BOM so important in PCBA processing?

BOM means bill of materials. The BOM of a product, which indicates how many parts the product needs to be assembled. All PCBA manufacturers need to purchase the materials required for this batch of production according to the BOM list provided by the customer, and evaluate the production cycle and process. It can be said that BOM is the most important part in all PCBA processing.

Since BOM is so important, what is its format?

In general, the product model, version model, preparation date, document number, total pages, etc. should be indicated at the beginning of the BOM. Every electronic product will continuously optimize its design or expand its functions in the whole life cycle from R&D to production and then to improvement. After the new version of the product data comes out, we must communicate with the PCBA manufacturer. The new version not only means the deletion of materials, but also the deeper problem is that the front-end design, including the schematic diagram, has been changed. At this time, all materials and quotations must be re produced, and the corresponding old versions must be marked as expired documents and sealed, and immediately stopped using. In order to ensure the orderly management of version and model, the release and online use of the BOM list of products must be issued by the R&D department, and at least signed and confirmed by the R&D engineer and the head of the R&D department at each level to ensure the correctness of the BOM list. The relationship between BOM and product can only be that multiple BOM correspond to one product, not that one BOM corresponds to multiple products, even if the two products are only different in the content of one label in PCBA.
