With the integration of PCBA production end and the maturity of the one-stop service model, more and more customers are looking for a supplier who can provide complete product services. However, it is necessary to have a certain understanding of the PCBA processing process before finding a satisfactory and suitable supplier. For many customers who want to adopt the entire PCBA outsourcing model, the specifics may not be well understood. The following Sanjing will share with you :

We know that no matter what you do, communication is a bridge that connects interpersonal relationships. Therefore, the first step in the entire PCBA processing process is communication. Regardless of the past SMT patch, PCB proofing half-pack mode or the current PCBA full-pack mode, business negotiations are required in the early stage, and mutual understanding and confirmation of each other's needs will be carried out before the next step.

The second is to evaluate the quotation. Regardless of the industry, since they want to cooperate, the two parties need to evaluate their respective costs. This requires communication on the price of the product. The PCBA processing plant will conduct an evaluation and quotation link based on the customer's BOM list and Gerber data.

3. The customer places an order. This process is that customers place corresponding orders according to their company's sales plan requirements and quantities. The SMT placement factory will analyze and evaluate the customer's product delivery date based on its own schedule and production capacity to determine whether the order delivery task can be completed within the customer's specified time. If the customer has no objection to the delivery date, both parties can confirm it in the form of a contract.

4. Procurement of components. Because it is PCBA one-stop service, electronic components must be purchased by PCBA factories. The PCBA processing plant will purchase related materials according to the customer's BOM list on the contract.

5. Incoming inspection. PCBA processing plants generally carry out incoming inspection and sample preservation for the purchased materials. Incoming inspection is because only products that pass the quality inspection can be used for production, and the seal preservation is convenient for customers to conduct back-inspection on the materials purchased by the supplier. . If there is a back inspection, it means that there is a problem with the components of the product. At this time, not only will it be reworked and repaired, but the trust of the customer may even be lost.

Sixth, PCBA manufacturing stage. This stage is the most important part of process and process control in field operations. Such as: solder paste mixing, solder paste printing, SPI solder paste inspection, SMT patch processing, reflow furnace 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, etc. Only after passing the test link designated by the customer's product, can the product affixed with the quality inspection label enter the packaging link.

8. Packing and transportation. Generally, after the PCBA manufacturing test is completed, packaging can be basically carried out. Packaging is generally divided into general packaging and anti-static packaging. The specific packaging method to be selected needs to be evaluated according to the characteristics of the customer's product, and then logistics is selected.

The above is about the entire PCBA processing process. After fully understanding these processes, you can choose a PCBA supplier. That's all for today's sharing, I hope it can be helpful to everyone!
