PCB). It includes the following major production processes:
1. Raw material procurement: Procurement of raw materials such as electronic components, PCBs, etc., to ensure the reliability and qualification of raw materials.
2. PCB manufacturing: making PCB boards, including design layout, printing, drilling, metallurgical chemical treatment, surface treatment and other process steps.
3. Component Procurement: Procurement of various electronic components, such as chips, resistors, capacitors and so on. This link usually requires cooperation with suppliers to ensure the procurement of components that meet the requirements.
4. Component placement: Precise soldering of electronic components onto the PCB board. This process can be accomplished by manual placement or automatic placement machines, and large-scale placement is usually done with automated equipment.
5. Welding and heat bending: the components have been mounted for welding, usually using hot air flow or reflow soldering and other processes. At the same time, for some need to bend the PCB board, but also need to carry out thermal curvature processing.
6. Test and debugging: the assembled PCBA has been completed to carry out the relevant functional tests to ensure that the quality and performance of the product meets the requirements.
7. Rework and Maintenance: Rework and maintenance of products with testing problems, correction of bad welding connections, replacement of problematic components, etc.
8.
8. Packaging and shipping: according to customer requirements for product packaging for storage and transportation. Finally, the finished product will be shipped to the customer.
The above is the main production aspects of PCBA processing, different processing in the specific operation and details may be different, the flexible application of these links and effective management is very important to ensure the quality of PCBA and improve production efficiency.
