2. Analysis of NeoDen's Core Fully Automated Production Line Products

To achieve true unmanned operation or minimal manual intervention, NeoDen has introduced a fully automated SMT production line comprising five core modules. Below are the technical highlights of the key equipment in each stage:

① High-Precision Fully Automatic Screen Printer: ND450 (Solder Paste Printer)

As the first process in the production line, the ND450 ensures extreme consistency in solder paste printing.

• Electrically Controlled Floating Squeegee Head: Features an innovative electrical and pneumatic design with continuous pressure monitoring to maintain constant pressure during printing, eliminating issues such as missed prints or excessive paste thickness.
• High-Precision Stencil Clamping: Utilizes dual-acting pneumatic cylinders for clamping, combined with CNC-machined crossbeams and high-precision linear guides, ensuring zero backlash after locking.
• 3-Axis PCB Adjustment Platform: An integrated 3-axis modular design, combined with a dedicated lead screw and nut mechanism to eliminate backlash, ensures extremely high precision in PCB position correction.
• Intelligent Cleaning System: Features a highly efficient stencil bottom cleaning module, coupled with a vacuum system, to ensure the stencil is as clean as new for every print.

② Solder Paste Inspection System: S1 SPI (Solder Paste Inspection)

After solder paste printing, the S1 SPI monitors print quality in real time to prevent defects from proceeding to the next process.

• High-precision imaging: Utilizes industrial-grade high-speed cameras to accurately detect solder paste volume, area, height, and offset.
• Closed-Loop Feedback: The S1 can synchronize data with the printer and pick-and-place machine to automatically adjust production parameters, significantly improving yield.

③ High-Speed Multi-Function Pick-and-Place Machine: N10P (Pick and Place Machine)

This is the core of the production line, responsible for precisely placing components onto the PCB.

• Exceptional Throughput: Equipped with 8 placement heads, it achieves a maximum speed of 20,000 CPH with placement accuracy as high as ±0.01mm.
• Intelligent Nozzle Change Function: Features 39 nozzle stations with automatic change capabilities, greatly enhancing production flexibility.
• Vision Recognition System: Utilizes a fourth-generation high-speed flying camera recognition system (ON Sensors, USA, with a 28mm industrial lens), supporting real-time imaging during operation to ensure both high efficiency and high precision.
• Support for Extra-Long Boards: Accommodates PCBs up to 1500 × 450 mm, making it ideal for the production of LED light strips and large backplanes.
• Feeding System: Supports up to 80 tape feeders and is compatible with a mix of electric and pneumatic feeders.

④ Eco-Friendly 12-Zone Reflow Oven: IN12C (Reflow Oven)

The NeoDen IN12C is an intelligent, automatic conveyor-type reflow oven that combines environmental friendliness with stable performance.

• Patented uniform heating plate: A unique heating module design ensures high thermal compensation efficiency, low power consumption, and minimal temperature variation across the surface.
• 12-zone heating design: Compact yet powerful, featuring heating elements imported from Switzerland and a Japanese NSK hot-air motor to ensure long-lasting durability.
• Built-in filtration system: Equipped with a soldering fume filtration system that effectively captures harmful gases, meeting the standards of high-end laboratories and cleanrooms.
• Energy-efficient and low power consumption: Operating power is only approximately 2.2 kW, resulting in significant savings on electricity costs compared to similar products.

⑤ Automatic Optical Inspection (AOI) Machine: ND800

Serving as the final quality control line of defense, the ND800 performs comprehensive inspection of finished PCBs.

• Comprehensive defect coverage: Detects various soldering defects, including missing components, misalignment, vertical placement, flipped components, short circuits, and cold solder joints.
• Intelligent algorithms: The software system is simple and intuitive, supporting lens calibration and automatic registration to quickly establish inspection programs.
• Stability: Monitors XY-axis origin signals and limit switches to ensure the camera's field of view covers the entire work area.
