1. Présentation du produit
The DEZ-H3800S, developed by Shenzhen DEZSMART Intelligent Technology Co., Ltd., is a cutting-edge in-line selective wave soldering machine designed to revolutionize PCB (Printed Circuit Board) soldering processes. As an integrated full-functional system, it combines flux spraying, preheating, and soldering onto a single XYZ motion platform, ensuring compactness without compromising performance.
Key to its design is a fixed PCB setup, where the spraying and welding platforms move dynamically—eliminating PCB displacement errors and enhancing soldering accuracy. Controlled entirely via a PC, it stores critical parameters (e.g., soldering temperature, flux type, nitrogen flow) for full traceability, making it ideal for high-precision electronics production.
2. Champ d'application
The DEZ-H3800S is widely applicable across industries requiring reliable, high-quality PCB soldering:
- Electronique grand public: Smartphones, laptops, and home appliances, where miniaturized components demand precise soldering.
- Automotive Electronics: Engine control units, sensors, and infotainment systems, where durability and consistency are critical.
- Industrial Control: Circuit boards for machinery, robotics, and power management, requiring stable performance in harsh environments.
- Médical Devices: Precision equipment like monitors and diagnostic tools, where soldering defects can impact safety.
3. Processus de travail
The DEZ-H3800S follows a streamlined, automated workflow, ensuring efficiency and repeatability:
- In-Line PCB Loading: PCBs enter the machine via SMEMA-compliant conveyor rails, with side clamping systems securing them in place.
- Selective Flux Spraying: Using the same XYZ motion platform, an imported piezoelectric jet valve applies flux precisely to target soldering areas (compatible with fluxes with <8% solid content).
- Dual-Side Preheating: Upper and bottom IR heaters warm the PCB to optimize flux activation, with adjustable heating ratios (0–100%) controlled via PC.
- Selective Soldering: A 15kg titanium alloy solder pot, equipped with servo-driven impellers and customizable nozzles (3mm, 4mm, 5mm, 6mm, 8mm), delivers controlled wave soldering. Nitrogen heating (up to 350°C) minimizes oxidation.
- In-Line Unloading: Completed PCBs exit the machine via the conveyor, ready for subsequent production steps.
4. Avantages principaux
Compared to conventional wave soldering machines, the DEZ-H3800S stands out with these unique benefits:
Space-Efficient Integration: By combining flux spraying and soldering on a single XYZ platform, it eliminates the need for separate stations, reducing floor space requirements significantly.
Superior Soldering Quality: With the PCB fixed in place, movement errors are eliminated. High-precision servo motors (Panasonic) and Hiwin ball screws ensure ±0.05mm positioning accuracy, boosting first-pass yield.
Flexible Modularity: SMEMA-compliant in-line transport allows easy integration into existing production lines, adapting to varying manufacturing needs.
Full Traceability: All parameters (solder temperature, flux type, paths) are stored in PC-configured files, enabling easy process replication and quality.
User-Friendly Operation: Windows 7-based software with real-time camera monitoring simplifies programming, even for operators with limited expertise.
