The electronic product production system is composed of the complete machine, the complete machine is composed of parts, the parts are composed of parts, electronic components and so on. The work of the system composed of the whole machine is mainly connection and debugging, and the work of production is not much. Therefore, the production process of electronic products we talk about here refers to the production process of the whole machine.
The assembly process of electronic products is to first assemble parts and components into components, and then assemble the components into a complete machine. Its work is to assemble components into circuit board components or components (PCBA) with certain functions. The electronic process we refer to basically refers to the assembly process of circuit board components.
In the circuit board assembly, it can be divided into machine automatic assembly and manual assembly. Machine assembly mainly refers to automatic patch assembly (SMT), automatic plug-in assembly (AI) and automatic welding. Manual assembly refers to manual plug-in, manual welding, repair and inspection, etc.
The preparation of production is the shaping of raw materials and components to be put into production, such as cutting feet of components, bending them into required shapes, arranging wires into required lengths, installing plug terminals and so on. The work must be finished before the assembly line is started.
Automatic SMT is to attach the SMT encapsulated components to the printed circuit board (PCB) by SMT technology, and then fix and weld them to the PCB by reflow welding process. After mounting the circuit board with surface encapsulated components, it is sent to the automatic insertion machine. The machine inserts the components that can be inserted into the corresponding position on the circuit board. After the bending Angle of the machine is preliminarily fixed, it can be transferred to the manual insertion wire. Artificial insert those who are not suitable for machine, machine components properly, after inspection into the crest welder or welding in the welding furnace, after welding circuit board individual unqualified parts by manual repair welding and repair, and then to the ICT static testing, functional testing and debugging, the performance of appearance inspection, such as process, complete the above process of circuit board to enter the machine assembly.
