What steps are needed for PCBA processing?
With the integration of PCBA production terminals and the maturity of the one-stop service model. At present, many electronic product companies are willing to find a professional supplier who can completely produce their own products. However, if PCBA customers do not fully understand the entire outsourcing model for the first time. Because I don't understand, misunderstandings will occur. Next, I will analyze the entire process of PCBA processing for you in detail.

1. Business communication. In fact, the business communication is the same as the previous SMT patch and PCB proofing, and the business negotiation stage must be carried out in the early stage. Are you sure I need it. I believe you can. Okay, next step.

2. Evaluate the offer. Electronic products undoubtedly need to do some communication on the price of the product, after all, both parties have costs to evaluate. The PCBA processing plant will evaluate the quotation based on the customer's BOM list and Gerber data. After confirmation, we can proceed to the next step.

3. Customer orders. This process is how much customers need to do according to their own product market sales and the company's planned needs. How many goods need to be prepared and how many orders need to be placed with the PCBA manufacturer. On the contrary, SMT SMT will analyze and evaluate the customer's product delivery date based on its own scheduling status and production capacity to determine whether the order delivery task can be completed within the time specified by the customer. The two parties can also accept the delivery date, or after coordination, determine it in the form of a contract. If possible, the next step.

4. Procurement of spare parts. Because it is a PCBA one-stop service, it is necessary to purchase electronic components from the factory. After the contract is signed, the PCBA processing plant will purchase materials according to the customer's BOM list.

5. Purchase inspection. As a qualified PCBA processing plant, checking and sealing the purchased materials is a daily operation. Because only qualified products can be used in production. Another special purpose of keeping the sample sealed is to facilitate the customer to check the materials purchased by the supplier. (Of course, it's best not to happen. If it happens, it means that there is a batch problem in the component of the product. Rework is a small matter, and losing the trust of customers is a big deal).

PCBA manufacturing stage. The whole stage is an important part of the field operation process and process control. Solder paste mixing, solder paste printing, SPI solder paste inspection, SMT chip processing, reflow oven temperature curve setting, AOI full inspection, dip plug-in wave soldering, etc.

PCBA test. Testing is a link that must be carried out after PCBA manufacturing is completed, including combustion, aging, and functional testing. Only through the test link designated by the customer's product, the product that has passed the 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 based on the customer's product characteristics before proceeding to the logistics link.

Through the combing of the above eight links, we can basically see which links we need to coordinate with the company and suppliers. After fully understanding, we can choose PCBA suppliers. Of course, different companies may have different ways of operating.
