Micro Parts & FPC Application Precision Visual Spot Welding System

The DW200P is a high-accuracy desktop resistance welding system designed for precision spot welding tasks in micro-electronics manufacturing. Engineered with a robust visual positioning module and closed-loop control, the DW200P delivers outstanding pressure and energy stability, ensuring clean, repeatable welds even on delicate components.

Combining a compact footprint with flexible MES connectivity, the DW200P integrates seamlessly into fully automated production lines. Its head and power supply module are lightweight and space-efficient, making it an ideal choice for high-volume manufacturers who need stable, traceable welding quality for sensitive micro-components.

Competitive Advantages

• Real-Time Welding Quality Control

  Monitor welding pressure dynamically and trigger alarms if thresholds are breached, ensuring stable, defect-free joints.

• Closed-Loop Energy Regulation

  Achieves rapid, stable discharge to prevent localized overheating, pad burns, or damage caused by uncontrolled heat diffusion.

• Precise Pressure Management

  Delivers pressure control with an error margin as low as ±5g. The system prevents pad collapse by maintaining consistent contact force during the weld cycle.

• Compact & Automation Ready

  Designed for easy integration into automated lines, with standard MES communication support for data tracking and process traceability.

Typical Applications

✓ Micro Speaker / Receiver
✓ Flat Vibration Motor
✓ Positioning Column Hot-Riveting
✓ Voice Coil Motor
✓ Linear Vibration Motor

✓ Enameled Wire Welding

✓ Thin Sheet Metal Welding

FAQ

Q1: How does DW200P improve my production yield?
A: Its high-precision energy and pressure control prevent common weld defects like pad burns or collapse, increasing first-pass yield and product consistency.

Q2: Can I monitor the welding process in real time?
A: Yes. The system continuously inspects pressure values during welding and alerts operators if readings move outside your set limits.

Q3: What kinds of parts can it handle?
A: DW200P is ideal for micro speakers, flat vibration motors, voice coil motors, and FPC lead connections — all of which demand fine-pitch, low-heat, consistent welds.
