PARMI’s Unique 3D SPI Strength

1. Perfect 3D Imaging of PCB

  • 3D imaging regardless of color, material, and surface roughness
  • Accurate 3D image profiling with laser centroid measurement technology

2. Real-Time PCB Warpage Tracking

  • Accurate measurement of warpage by scanning the entire area of the PCB with PARMI’s exclusive technology
  • Base acquisition by the real-time Z-axis control and PCB scanning
  • Guaranteed measurement accuracy for warpage up to ± 5mm

3. Provide and Compensate Data of PCB Stretch and Shrinkage Rate

  • Calculate the stretch and shrinkage rate of the PCB by comparing its fiducial mark coordinate value based on the gerber data

4. Real-Time Closed Loop System

  • Optimization of SMT process through real-time feedback and feedforward
    – Feedback System : Feedback the location information between the PCB and the stencil mask to the printer
    – Feedforward System : Feedforward the location information of solder paste to the chip mounter

5. Printer Doctor

  • PARMI’s know-how accumulated over many years in the screen printing process
    : ‘Fast identification and correction of screen printer setup errors’, ‘root cause analysis’, ‘defect prevention’, and ‘process trend analysis’
  • Maximization of printing process stability and production yield
