The main components of the Full-auto SMT Production Line are composed of surface mount components, circuit substrates, assembly design, and assembly processes. The main production equipment of the Full-auto SMT Production Line includes printers, dispensers, placement machines, and reflow Soldering furnace and wave soldering machine. In addition, as the auxiliary equipment of the Full-auto SMT Production Line, there are testing equipment, rework equipment, cleaning equipment, drying equipment, and material storage equipment. Next, I will talk about the technical principles of the Full-auto SMT Production Line using this equipment.
What is the technical principle of the Full-auto SMT Production Line?
What are the advantages of the full-auto SMT Production Line technology principle?
What are the implementation steps of the technical principle of the Full-auto SMT Production Line?
First of all, Full-auto SMT Production Line is completed by surface assembly technology. Full-auto SMT Production Line is a new generation of electronic assembly technology developed from hybrid integrated circuit technology to adopt component surface mount technology and reflow Welding technology has become a new generation of assembly technology in the manufacture of electronic products.
Therefore, as the main technical principle of Full-auto SMT Production Line, its technology has a wide range of applications. On the one hand, the Full-auto SMT Production Line promotes the miniaturization and multi-function of electronic products; on the other hand, the Full-auto SMT Production Line provides conditions for mass production and low defect rate production.
Printing: Its function is to print solder paste or patch glue onto the PCB pads to prepare for the soldering of components. The equipment used is a printing machine (stencil printing machine), located at the forefront of the Full-auto SMT Production Line.
Dispensing: It is to drop the glue onto the fixed position of the PCB, and its main function is to fix the components to the PCB. The equipment used is a dispenser, located at the forefront of the Full-auto SMT Production Line or behind the testing equipment.
Mounting: Its role is to accurately mount surface mount components to a fixed position on the PCB. The equipment used is a placement machine, located behind the printing machine in the Full-auto SMT Production Line.
Curing: Its function is to melt the patch glue, so that the surface mount components and the PCB are firmly bonded together. The equipment used is a curing oven, located behind the placement machine in the Full-auto SMT Production Line.
Reflow soldering: Its function is to melt the solder paste, so that the surface mount components and the PCB are firmly bonded together. The equipment used is a reflow oven, located behind the placement machine in the Full-auto SMT Production Line.
Cleaning: Its function is to remove the solder residues such as flux that are harmful to the human body on the assembled PCB. The equipment used is a washing machine, and the location may not be fixed, it may be online or offline.
Inspection: Its function is to inspect the welding quality and assembly quality of the assembled PCB. The equipment used includes magnifying glass, microscope, in-circuit tester (In-Circuit Tester, ICT), flying probe tester, automatic optical inspection (Automated Optical Inspection, AOI), X-RAY inspection system, functional tester, etc. According to the needs of inspection, its location can be equipped with a suitable place for Full-auto SMT Production Line.
Rework: Its function is to rework the PCB that has been tested for ancient costumes. The tools used are electric soldering irons, rework stations, etc., which are configured at any position in the Full-auto SMT Production Line.
