How much do you know about the process of PCBA processing?
With the integration of PCBA production end and the maturity of the one-stop service model. At present, many electronic product companies are also willing to find a professional supplier who can fully produce their products. However, if it is a new purchase or the first time to take the entire PCBA outsourcing model, it is likely that many customers have not fully understood it. Because I don't understand it, misunderstandings will occur. So today, the editor of Jingbang Electronics will analyze the whole process of PCBA processing in detail with you.
1. Business communication. Business communication is actually the same as the previous half-package mode of SMT patch and PCB proofing separately, and a business negotiation stage must be carried out in the early stage. You are sure I need it, I am sure you can do it. Ok, next step.
2. Evaluate the quotation. Making electronic products undoubtedly requires a certain degree of communication on the price of the product, after all, both parties have a cost that needs to be evaluated. The PCBA processing factory will conduct an evaluation and quotation link based on the customer's BOM list and Gerber data. After confirming, everyone can proceed to the next step without any problems.

3. The customer places an order. This process is how much customers need to do according to their own product market sales and the company's planned needs. How many stocks are needed, how many orders will be placed with the PCBA manufacturer. On the contrary, the SMT placement factory will analyze and evaluate the customer's product delivery according to its own schedule and production capacity to determine whether it can complete the order delivery task within the time specified by the customer. Both parties can also accept the delivery date, or it can be confirmed in the form of a contract after coordination. If possible, the next step.
4. Procurement of components. Because it is a one-stop service for PCBA, a factory is necessary to purchase electronic components. After the contract is signed, the PCBA processing plant will purchase materials according to the customer's BOM list.
5. Incoming inspection. As a qualified PCBA processing plant, it is a routine operation to inspect and seal the purchased materials. Because only products that pass the quality inspection can be used in production. Another special use of sealed samples is to facilitate customers to re-inspect the materials purchased by suppliers. (Of course, this situation is best not to occur. If it does, it means that there is a batch problem of the product's components. Rework is a trivial matter, and it is a major matter to lose the trust of customers).
Sixth, PCBA manufacturing stage. The entire stage is the link with the most process and process control in field operations. Solder paste mixing, solder paste printing, SPI solder paste inspection, SMT patch processing, reflow oven temperature curve setting, AOI full inspection, DIP plug-in wave soldering, etc.
Seven, PCBA test. Testing is a link that must be carried out after PCBA manufacturing is completed, including programming, burn-in, functional testing and so on. Only after passing the test link designated by the customer's product, can the product with the PASS seal enter the packaging link.
8. Packing and transportation. After the PCBA manufacturing test is completed, the packaging can be carried out after reaching the customer's standard and approval. There are general packaging and anti-static packaging. This needs to be evaluated according to the customer's product characteristics, and then the logistics link can be used.
Basically, after sorting out the above 8 links, we can see which links we need to coordinate with the company and suppliers, and then we can proceed with the selection of PCBA suppliers after we fully understand them. Of course, different companies may have different operating methods
