1. Dual-Vision Automatic Optical Alignment System
Utilizes twin high-definition CCD cameras (1.3MP) to capture real-time images of both the PCB and the BGA component.
Advanced image processing software performs automatic analysis and offset correction, achieving a repeat placement accuracy of ±0.01mm.
Enables fully automatic recognition and alignment for chips ranging from 10x10mm to 90x90mm, eliminating human error and ensuring perfect placement every time.
2. Advanced Multi-Zone Intelligent Heating System
Precise Control: Features 5 K-type thermocouples for closed-loop temperature feedback. Each of the three main heating zones employs independent PID algorithms for uniform and accurate heat distribution.
Superior Heating Design:
Upper Heater: Integrated hot-air nozzle and placement head, utilizing a fan-style heater.
Lower Heater: A square honeycomb-style hot-air heater with a unique thermal flow channel for precise bottom-side heating (requires clean, oil-free compressed air at 5 bar).
Infrared Preheater: A large-area carbon fiber infrared preheater with a high-temperature glass surface. This is the core of our infrared BGA reballing station, which prevents PCB warping during the entire rework process.
Unmatched Flexibility: Both upper and lower zones support 8-stage temperature profiles, which can be stored, recalled, and analyzed for different BGA types. The lower mobile heating zone can be programmed to move and adjust height automatically.
Rapid Cooling: A high-power cross-flow fan provides rapid cooling to solidify joints and prevent board deformation.
3. Automated Operation & Control System
Runs on a user-friendly Windows-based computer control system. Complex soldering and desoldering station operations are simplified into one-click functions for removal, placement, and reflow.
Achieves full automation: auto-alignment, auto-placement, auto-soldering, and auto-desoldering. The upper head uses a Panasonic servo system for precise independent control of height and placement.
Features automatic profile generation and report logging for quality traceability. The system maintains comprehensive work logs with massive storage for easy retrieval of historical data and parameters.
4. Comprehensive Safety & Protection System
Equipped with CE certification and features multiple safety protocols including an emergency stop switch and dual over-temperature protection with auto-shutdown.
Includes an audible “pre-alarm” function that alerts the operator 5-10 seconds before cycle completion.
The cooling system operates automatically until the board reaches a safe ambient temperature, prolonging machine lifespan.
Photoelectric safety grating is installed for operator protection during operation.
