Complete set of finished products for patch processing

Complete set of finished products for patch processing
In daily life, electronic products can be seen everywhere. The end users get the product packaging with plastic packaging, and how to produce a complete set of products in front of the shelf. I believe many people do not understand what the process or steps are. So today I tell you that the smt chip processing package has been made
1. Business communication
The salesperson finds the customer who needs to produce and process electronic products or contacts the original equipment manufacturer, including the price of the patch, whether it is the original equipment manufacturer's information, delivery time, quality qualification rate, etc. These are usually early business communications
2. Quotation evaluation
After in-depth understanding in the preliminary business communication, we have a preliminary understanding of the scale, strength and reputation of both parties, and then review the BOM list to evaluate and analyze the quotation. After the quotation, Party A will evaluate the quotation.
Circuit board

3. Audit
At this stage of factory audit, some companies are conducting quotation evaluation. If the relationship is familiar, factory audit is to check the company's certification qualification, factory equipment, management level, production status, production environment, etc.
Sign the contract and the customer places an order
After communication, quotation evaluation, factory audit, etc., the contract is signed, and both parties agree on the terms and responsibilities for breach of contract. After the contract is signed, the customer can place an order.
5. Parts procurement
After the customer places an order, they need to purchase components according to the bom order. According to the contract, if it is an OEM, it will be provided by the customer. If it is an OEM, it needs to be purchased by the placement factory. The procurement of components will take some time. At the same time, due to the current shortage of integrated circuits and the lack of inventory of supply chain goods, the procurement of spare parts is more troublesome.
6、 Incoming inspection
Before production and processing, the purchased or customer supplied materials must be carefully checked. If the product has batch problems due to component quality problems, on the one hand, it will consume human, material and financial resources; on the other hand, the most important thing is to affect the delivery time and customer trust. Recall that the incoming inspection must be taken seriously by every chip processing factory.
7. Manufacturing
After the parts are in place and the incoming materials are inspected, the equipment must be debugged and programmed in advance, and the first production must be carried out. After the first production, optimize the program of the production line equipment after passing various tests and inspections, and then conduct mass production.
8、 PCBA test
After PCB installation and welding, it will become a PCBA board. In daily life, various components in electronic products will appear on the circuit board The board needs to cut, split, clean, and some boards need to be coated with 3 anti paint After these processes are completed, various tests are carried out, including functional test, drop impact test, high and low temperature test, constant temperature test, salt spray test, etc Not all PCBA will conduct these process tests, which need to be analyzed and handled
9、 Assembly
If the customer only needs the circuit board, and then the PCBA test has been completed, it can be delivered to the customer If the finished product is delivered to the customer, then it needs to be assembled Assembly is a production line with many people. Each production line station is responsible for a process, and then flows to the next station through the belt conveyor After assembly, some electronic products must undergo aging test
10. Packaging
After the aging test is completed, the products are returned to the production line, packaged in large quantities through packaging, plastic sealing, etc., and then enter the warehouse for shipment.
