With the integration of PCBA production end and the maturity of one-stop service mode. At present, many electronic product enterprises are willing to find a professional supplier who can produce their own products completely. However, if PCBA customers do not fully understand the whole outsourcing mode for the first time. Because I don't understand, there will be misunderstanding. Next, I will give you a detailed analysis of the whole process of PCBA processing.
1、 Business communication. In fact, business communication is the same as the previous SMT patch and PCB proofing separately, and it is definitely necessary to conduct a business negotiation stage in the early stage. You're sure I need it. I'm sure you can. OK, next step.
2、 Evaluate the offer. Electronic products no doubt need to do some communication on the price of products, after all, both sides have a cost to evaluate. PCBA processing plant will evaluate the quotation according to the customer's BOM list and Gerber data. After confirmation, we can go to the next step without any problems.
3、 Customer orders. This process is how much customers need to do according to their own product market sales and the company's planned demand. How many goods should be prepared and how many orders should be placed with the PCBA manufacturer. On the contrary, SMT SMT will analyze and evaluate the customer's product delivery time according to its own scheduling status 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 after coordination, determine it in the form of a contract. If it can, the next step.
4、 Purchase of components. Because it is PCBA one-stop service, it is necessary for factories to purchase electronic components. After the contract is signed, PCBA processing plant will purchase materials according to the BOM list of customers.
5、 Incoming inspection. As a qualified PCBA processing plant, it is a routine operation to inspect and seal the purchased materials. Because only qualified products can be used for production. Another special use of sealed sample preservation is to facilitate the customer to inspect the materials purchased by the supplier. (of course, it's better not to happen. If it happens, it means that there are batch problems in the components of the product. Rework is a small matter, and losing the trust of customers is a big thing).
6、 PCBA manufacturing stage. The whole stage is the most important part of process and process control in field operation. Solder paste mixing, solder paste printing, SPI solder paste detection, SMT chip processing, reflow furnace temperature curve setting, AOI full inspection, dip plug-in wave soldering, etc.
7、 PCBA test. Testing is a link that must be carried out after PCBA manufacturing is completed, including burning, aging, functional testing and so on. Only through the test link specified by the customer's product, the product with pass seal can enter the packaging process.
8、 Packaging 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 followed.
Basically, after sorting out the above eight links, we can see what links we need to coordinate with the company and suppliers. After fully understanding, we can select PCBA suppliers. Of course, different companies may operate in different ways.
