Accurate Chip Reballing
The DH-A5 is a professional-grade, automated BGA rework station designed for precision soldering and repair of modern electronics. It is the ideal mobile repairing machine for advanced workshops.
The DH-A5 redefines precision in electronics repair. This industrial-grade BGA rework station is engineered for flawless soldering, component placement, and removal of BGA, CSP, and QFN packages. Integrating an embedded IPC, PLC control, and real-time thermal profiling, it delivers the accuracy and repeatability demanded by modern mobile phone repair tools & equipments and complex SMT rework applications. This intelligent mobile repairing machine sets a new standard for reliability in professional workshops.
At the heart of this rework station soldering system is an embedded industrial PC coupled with a high-definition touchscreen HMI and PLC.
Dual-Curve Real-Time Display: The interface simultaneously shows both the set and actual temperature profiles, allowing for instant visual comparison and verification.
Instant Curve Analysis & Correction: Proprietary software provides live analysis during the reflow process, identifying deviations and suggesting corrections to guarantee perfect soldering joints every time.
Secure Data Management: Features password-protected access and extensive profile storage for different BGA types, making it a leader in data-driven process control among professional mobile phone repair tools & equipments.
Achieving consistent results starts with unparalleled thermal control, maintained within a ±2°C deviation.
Closed-Loop K-Type Thermocouple Control: Works in tandem with the PLC and dedicated temperature modules for fully automatic compensation and stability.
External Calibration Interface: Allows for independent verification and precision calibration using third-party metrology tools, ensuring absolute trust in the thermal data.
Three-Zone Independent PID Heating: Independent control over top, bottom, and preheat zones using advanced PID algorithms. Each zone supports up to 8 programmable segments, enabling synchronized multi-stage heating for perfectly even PCB temperature distribution.
Accuracy is guaranteed by a combination of superior vision and mechanized control.
Digital Vision Alignment System: A high-resolution optical system with joystick control provides a complete, unobstructed view of the BGA’s corners and center, eliminating “blind spots.”
Servo-Driven Motion Control: High-response servo motors drive the X, Y, and Z axes, enabling both fine micro-adjustments and rapid positioning. The V-groove PCB platform accommodates boards of various sizes and layouts.
Full Automation Suite: Integrated BGA auto feeder and catcher system completes the pick-place-solder-catch cycle, transforming this mobile repairing machine into a highly efficient, smart production cell.
Every detail is crafted for optimal results and operator safety.
Universal Flexible Fixtures: Protect PCB edges from damage and prevent board warping during heating, adapting to a wide range of component sizes.
360° Rotatable Titanium Nozzles: Available in multiple specs for easy installation, ensuring targeted hot air flow.
Smart Cooling & Alert Systems: A high-power cross-flow fan ensures rapid cooldown to prevent PCB deformation. An audible pre-alert function notifies the operator 5-10 seconds before cycle completion. An automatic post-operation cooldown cycle protects the machine’s longevity.
Safety & Compliance: CE certified and equipped with emergency stop and auto power-off protection.
