Brief: In this video, we provide an in-depth look at the WDS-620 Optical Alignment BGA Rework Station. You'll see a detailed demonstration of its semi-automatic operation, including how the optical alignment system precisely centers BGA chips and the three-zone heating process that prevents PCB deformation. Watch to understand the machine's five operational modes and its advanced temperature control capabilities for professional PCB rework.
Related Product Features:
  • Features five operational modes: Remove, Mount, Weld, Manual, and Semi-auto for versatile rework applications.
  • Independent three-zone heating system with upper hot air, lower hot air, and bottom IR heating for precise temperature control.
  • High-precision optical alignment system with HD CCD camera, auto-focus, and 15-inch LCD monitor for accurate chip placement.
  • Advanced temperature control using K-type thermocouples with ±1℃ precision and PID self-setting parameters.
  • Multi-functional human-machine interface with HD touch screen and micrometer fine-tuning for X, Y, and R angle adjustments.
  • Safety protection features including automatic alarm after welding and dual over-temperature protection circuits.
  • Supports PCB sizes from 10x10mm to 500x380mm and chip sizes from 1x1mm to 80x80mm for various applications.
  • Equipped with 360-degree rotatable titanium alloy nozzles and laser positioning for fast centering and component alignment.
Faqs:
  • What are the main operational modes available on the WDS-620 BGA Rework Station?
    The WDS-620 offers five operational modes: Remove for taking off components, Mount for placing new chips, Weld for soldering, Manual for custom operations, and Semi-auto for assisted rework processes. These modes can be freely switched according to your specific needs.
  • How does the temperature control system ensure precision during BGA rework?
    The station features an independent three-zone heating system with closed-loop control using high-precision K-type thermocouples. This allows temperature control within ±1℃ accuracy, with PID self-setting parameters and real-time curve analysis displayed on the touch screen for optimal thermal management.
  • What safety features does the WDS-620 incorporate to protect both the operator and the PCB?
    Safety is ensured through multiple protections including an automatic alarm after welding completion, dual over-temperature protection that automatically cuts power in case of temperature abuse, and password protection for temperature parameters to prevent unauthorized modifications.
  • How does the optical alignment system assist in precise component placement?
    The HD CCD optical system provides beam splitting, magnification, fine adjustment, and auto-focus capabilities with automatic color and brightness adjustment. Combined with laser positioning and a 15-inch monitor, it ensures accurate centering and placement of BGA chips.
