What is the maximum and minimum PCB thickness this machine can support?
The WDS-650 is designed to handle a wide range of board thicknesses, ranging from 0.4mm to 5.0mm. This makes it suitable for both ultra-thin mobile phone motherboards and thick industrial control boards or server motherboards without causing deformation.
What types of chips can this machine repair?
This machine is specifically designed for high-density surface-mount technology (SMT) components. It can effectively repair:
BGA (Ball Grid Array)
CSP (Chip Scale Package)
QFN (Quad Flat No-leads)
LGA (Land Grid Array)
QFP (Quad Flat Package)
Does the machine come with a camera and display system?
Yes, the WDS-650 features a 15-inch high-definition LCD display. It is equipped with an industrial-grade HD camera with HDMI output, allowing for precise optical alignment of BGA chips to ensure accurate rework.
What is the heating method used?
The machine utilizes a dual heating system combining Hot Air and Infrared (IR) technology. It features multiple temperature zones (top and bottom) to ensure uniform heating of the PCB, preventing cold solder joints and short circuits.
How precise is the alignment mechanism?
The WDS-650 offers high-precision optical alignment. The system provides an alignment accuracy of ±0.01mm, which is critical for repairing fine-pitch chips found in modern smartphones and laptops.
Is the temperature control system automatic?
Yes, the machine employs a closed-loop temperature control system using K-type thermocouples. This ensures stable temperature control during the rework process, preventing overheating and damage to sensitive components.
What surface treatments are recommended for the machine’s base?
For the structural base and table, Cast Iron (HT300) is typically used for its excellent vibration damping properties. For moving parts or rails, Hardened Steel or Nitrided Steel with Nitride Coating is recommended to ensure long-term wear resistance and smooth operation.
What is the power requirement for this equipment?
Typically, a machine of this class requires a standard industrial power supply (e.g., AC 220V or 110V depending on region) with a power consumption of approximately 4000W – 5000W. Ensure your workshop has a stable power source and proper grounding before installation.
