WDS1800 Introduces Highprecision Automated BGA Rework System

In the realm of precision electronics manufacturing and repair, the rework accuracy and efficiency of complex components such as BGAs, POPs, QFNs, and CCGAs remain critical industry concerns. Traditional manual or semi-automated rework methods are not only time-consuming and labor-intensive but also struggle to maintain consistently high yield rates, especially as electronic products continue trending toward miniaturization and high-density designs.

Against this backdrop, the emergence of the fully automated WDS1800 BGA rework system marks a new era of intelligent, high-precision electronic component repair technology.

The WDS1800 achieves exceptional rework performance through the integration of multiple innovative technologies:

Equipped with a 12-megapixel industrial vision camera, the system delivers powerful automatic Mark point recognition. By precisely capturing coordinate information, it achieves positioning accuracy up to 10μm, ensuring flawless alignment between chips and PCB pads. This capability proves particularly crucial for micro-pitch, densely packaged components, effectively eliminating defects caused by manual alignment errors.

The system innovatively combines infrared and hot air (nitrogen or compressed air) heating methods with an independent three-zone design: top hot air zone, bottom hot air zone, and large-area infrared preheating zone. The bottom infrared preheating platform utilizes German-made Elstein far-infrared heating panels for rapid, uniform heating across a 550×400mm area. The "preheat first, then heat" strategy significantly reduces temperature loss during PCB heating, preventing deformation caused by localized overheating or excessive temperature differentials.

The eight-axis independent drive design enables completely automated chip pickup, alignment, soldering, and removal processes. The X/Y movement design maximizes workspace efficiency, allowing the relatively compact machine to handle large PCBs (up to 640×490mm, customizable). Independent heating and installation heads with auto-rotation further enhance operational precision.

The integrated vacuum pump system, combined with high-precision stepper motor control and micro-adjustable installation nozzles, enables precise chip handling with pressure control under 10 grams. The system even supports zero-pressure placement, making it ideal for microchip processing while ensuring soldering reliability.

• Automated Batch Processing: Parameter-driven operation with memory function enables efficient batch rework.
• Flexible Heating Zone Movement: Top and bottom heating zones automatically position themselves for optimal thermal management.
• Advanced Data Capabilities: Built-in industrial computer supports real-time temperature curve display with 10-segment control and storage for over 10,000 profiles.
• Safety Features: Dual optical safety barriers immediately halt operation upon obstruction detection.
• Optional Enhancements: Includes solder ball observation cameras, nitrogen protection interfaces, and manual chip cooling functions.

The WDS1800 handles virtually all BGA and challenging component types, including POP, CCGA, QFN, CSP, LGA, Micro SMD, and MLF configurations.
