Production Introduction



Fully Automated Placement
Electronic Package
Efficient Assembly
Mounter is an automated equipment used for surface mount production of electronic components. Its working process includes preparation work, placement strategy setting, loading, precise positioning, placement, welding, inspection and unloading and other steps. In this process, the placement machine can accurately position and mount the components to be mounted on the PCB board, and finally ensure the quality of the product through inspection.
Electronic packaging is the process of encapsulating electronic components in a housing to protect the components and facilitate connection and use with other components or devices. The process generally includes several links such as selecting the appropriate packaging material and shape, installing on the PCB board, welding and quality inspection. In these processes, precise machinery and equipment, automated cooperation and rigorous quality inspection processes are required to ensure the stability and reliability of semi-finished and finished products. At the same time, with the development of electronic devices, the packaging process is also constantly evolving and updating.
Efficient assembly refers to maximizing the production efficiency and quality stability of electronic packaging through automated equipment and process control in the shortest possible time. The entire assembly process includes material procurement, process design and optimization, automation equipment selection and commissioning, personnel training and operation, and continuous monitoring and improvement. The advantages of an efficient assembly process lie in its rapid response to market demand, reduction of production costs, assurance of product quality stability, and increased production capacity.
