Thailand’s smartphone assembly sector is rapidly growing, driven by demand for advanced features such as wireless charging and magnetic accessories. One critical component is the magnetic ring used for wireless charging on smartphones, which requires precise adhesive dispensing on irregular 3D surfaces. Traditional manual dispensing often leads to inconsistent glue volumes, misalignment, and low yield, limiting production efficiency.

To address these challenges, a leading Thai smartphone parts manufacturer adopted the PD500D High Precision Robot Dispensing Machine. The system supports five-axis motion, enabling accurate 3D dispensing on complex geometries while maintaining consistent glue volume and placement. The integration of a high-resolution 3D vision system ensures precise alignment of the magnetic ring, reducing defects and rework.
Optimized Dispensing Solution for 3D Surfaces

The PD500D offers:

• Five-axis linkage motion for curved, inclined, or irregular smartphone components
• 3D visual inspection and alignment to compensate for material tolerances
• Stable glue flow control to prevent overflow and ensure uniform bonding
• Dual-station optional configuration to increase unit per hour (UPH) and minimize idle time

This combination of precision motion and vision-guided control allows the factory to maintain high yield even with complex component designs, meeting the strict quality standards of the global smartphone supply chain.

 
Production Results in Thailand

After implementation, the manufacturer reported:

• Significant improvement in assembly efficiency for magnetic rings
• Reduced adhesive waste and elimination of misalignment defects
• Higher first-pass yield and fewer reworks
• Consistent performance across multiple shifts with minimal operator intervention
• Ability to handle irregular 3D shapes without compromising quality

The PD500D system also supports integration with low-viscosity and high-viscosity adhesives, providing flexibility for future smartphone design iterations.

Enabling Smart Manufacturing in Thailand

As Thailand continues to expand its electronics manufacturing capacity, automated robotic dispensing solutions like the PD500D are helping factories upgrade from manual to precision-controlled assembly. By combining high-precision motion control, 3D visual guidance, and flexible adhesive handling, manufacturers can enhance efficiency, improve yield, and maintain competitiveness in the increasingly sophisticated global smartphone market.
