In South Korea’s competitive camera module (VCM) manufacturing sector, precision and consistency are critical to maintaining product quality. A Korean optical components manufacturer recently adopted our Vibration Motors Desktop Spot Welding System for the enameled wire welding process in VCM (Voice Coil Motor) assembly.

Customer Challenges

Previously, the customer relied on fully manual welding, which caused several production issues:

• Low productivity and unstable UPH (Units Per Hour)
• Inconsistent welding strength and poor appearance uniformity
• Frequent insulation layer damage during welding
• Difficulty maintaining yield rates due to manual alignment errors

The customer sought a semi-automated alternative to replace traditional Korean thermal welding systems with a more stable, precise, and efficient local solution.

 
Our Solution

We supplied a Desktop Spot Welding System specifically optimized for VCM enameled wire welding.
Key features include:

Micro-Pressure Welding Head:
Minimum welding pressure 40g ±5g, effectively preventing insulation layer breakdown.
High-Speed Transistor Power Source:
Real-time current feedback and control every 10 microseconds, ensuring consistent welding energy, strong bonding strength, and stable appearance.
Semi-Automatic Control System:
Upgraded from manual to semi-automatic operation, improving process stability and operator efficiency.

Customer Results

After implementation, the Korean manufacturer reported remarkable improvements:

• Achieved UPH of 1800–2000 units/hour
• Enhanced product yield and consistency
• Reduced insulation damage and rework rate
• Successfully replaced traditional hot-press welding equipment with a domestic high-precision solution

Why This Matters for the Korean Market

As camera modules and VCM components evolve toward higher precision and miniaturization, Korean manufacturers are increasingly adopting semi-automated, micro-force spot welding solutions to ensure quality stability and higher throughput.

Our Vibration Motors Desktop Spot Welding System provides a proven, high-yield alternative that meets the demanding standards of Korean VCM assembly lines—bridging performance, reliability, and cost efficiency.
