High quality technology leads to high quality products.We are establishing an advanced quality control system by making PWBs in connection with the strict quality control systems for automobiles. By thorough factory cleaning, we maintain a clean environment free of fine particles and dust.
In addition, we are working on an environment that eliminates product defects via detailed inspections from Flying Probe Testers.

• Flying Probe Tester
  
  

  By bringing in Flying Probe Testers, we are able to do electrical continuity tests for small to medium lot products.
• AOI
  
  

  Through the AOI checking system, we are able to conduct strict inspections and quality control even in fine details.
• Visual Inspection Machine (VISPER)
  
  

  By bringing in a visual inspection machine, we can detect appearance defects in the finished product.
• Hole Checker
  
  

  By bringing in the hole checker we are able to inspect the number of holes, diameters and defects in the through holes.
• Cross-section Inspection
  
  

  Through-hole plating ensures high reliability via cross-section inspection.
• Impedance Control
  
  

  Impedance control is done by regulating pattern width and interlayer thickness. By using impedance calculation software; "Si 8000", manufactured by Polar Instruments, it is possible to suggest the appropriate layer structure, line width, and line spacing at the pattern design stage. By using "CITS880", manufactured by Polar Instruments, impedance measurement results for completed PWB can also be submitted.
