SMT (Surface Mount Technology) Inspection and Post-Soldering Processing Equipment Combination

Equipment Composition and Functionality

AOI Inspection Stage

AOI Equipment:

An Automated Optical Inspection machine utilises high-definition cameras and optical systems to conduct comprehensive inspection of post-soldering PCB boards. It identifies defects such as cold solder joints, bridging, missing components, and component misalignment, thereby ensuring product soldering quality.

0.59 Transfer Basket Station: Transfers PCBs from conveyor tracks to the AOI inspection station, enabling automated loading and unloading.

2.8 Translator: Facilitates horizontal movement of PCBs during inspection, ensuring process continuity.

800×800 Workbench: Provides an installation and operating platform for AOI equipment or peripheral auxiliary devices, optimising equipment layout.

Post-Soldering Processing Stage

Dual-Track Reflow Oven: Achieves solder paste melting and solidification through multi-zone heating (preheating, reflow, cooling), establishing permanent component-to-PCB connections. The ‘dual-track’ design processes PCBs from two production lines simultaneously, substantially boosting efficiency.

Complementary Conveying and Control Equipment: Ensures stable PCB transport within the reflow oven while enabling precise control of process parameters such as temperature and timing.

Production Line Features

High Inspection Accuracy:

AOI equipment employs high-precision optical recognition technology to detect micron-level soldering defects, meeting stringent soldering quality requirements in consumer electronics, automotive electronics, and similar sectors.

Seamless Process Integration:

Automated transfer between reflow soldering and AOI inspection is achieved via transfer and translation mechanisms, reducing manual intervention while enhancing production efficiency and inspection consistency.

Modular Design:

Each unit operates independently yet combines flexibly. The number of AOI systems and reflow oven specifications can be adjusted according to production line scale and inspection requirements, adapting to diverse manufacturing capacities.

This integrated system serves the back-end processes of SMT production lines, providing reliable assurance for electronic PCB board soldering quality. It finds extensive application in the mass production of electronic products including mobile phones, computers, and industrial control boards.
