  • Rich experience in substrate artwork design
    We have experience for substrate artwork design for several hundred types, from paper phenol single-sided substrates to 12-layer substrates.
  • Construction of optimal inspection equipment
    We construct optimal inspection equipment based on the needed specifications, such as print substrate inspections, finished product inspections, and wireless-related inspections.
  • Material provision, acceptance inspection, storage / management
    We have experience procuring generic and exclusive parts from 300 companies.
    Depending on your needs, we also perform an acceptance inspection.
    For material storage, we have equipment for strict temperature / humidity and refrigeration management.
  • Suggestions for optimization
    We offer suggestions for optimization to our customers through design feedback that we discovered during manufacturing.
  • Obsolete part information
    We not only release information, such as notices of changes or stopping production from parts manufacturers, we also search for replacements of obsolete parts.
  • Realizing environmentally friendly products
    We not only have a structure to fit needs such as RoHS support and green procurement measures at each company, we can also support operations such as surveys.
  • Quality management system
    We create a QC workflow chart for each product and procedure according to those directions. Also, we perform serial management for the products we have manufactured.
