How do you assemble electronic parts?
The electronic product system is composed of the whole machine, the whole machine is composed of parts, and the Electronic Components are composed of parts and components. The work of the system composed of the whole machine is mainly connection and debugging, and there is not much production work, so the production process of electronic products we are talking about here refers to the production process of the whole machine.
The mixed assembly process of electronic products is to first assemble parts and components into components, and then assemble the components into a complete machine. Its core work is to assemble the components into buile-up printed board components or components (PCBA) with certain functions. The electronic process referred to in this book basically refers to the assembly process of circuit board components.
In the PCBA Manufacturing , it can be divided into two types: automatic machine assembly and manual assembly. Machine assembly mainly refers to automatic sheet metal assembly (SMT), automatic plug-in assembly (AI) and automatic welding, and manual assembly refers to manual plug-in, manual repair welding, repair and inspection, etc.
Production preparation is to reshape the raw materials and components to be put into production, such as cutting the feet of the components, bending them into the required shape, sorting the wires into the required length, installing the plug-in terminals, and so on. These tasks must be completed before the assembly line starts.
Automatic SMT is the use of Surface-Mount (SMT) &BGA Assembly to mount the components of the SMD package on the printed board, and then fixedly solder it on the printed board through the reflow soldering process.
The circuit board with surface-mounted components is sent to the automatic plug-in machine, and the machine inserts the machine-insertable components into the corresponding position on the circuit board. After the machine is preliminarily fixed at the corners, it can be transferred to the manual plug-in wiring. NS.
Manually insert those components that are not suitable for machine insertion and machine attachment, and then send them to the wave soldering machine or dip soldering furnace for soldering after inspection. The individual unqualified parts of the circuit board after soldering are manually repaired, repaired, and then carried out. ICT static testing, functional performance testing and debugging, appearance testing and other testing procedures, the circuit board after completing the above procedures can be assembled into the whole machine.
