High Density Interconnect PCBs

High-reliability and high layer count PCBs for a wide variety of high-performance products ranging from cutting-edge ICT devices to social infrastructure and industrial equipment.

  • Propose materials and layer construction to match each customer’s needs for electric characteristics including characteristic impedance and transmission characteristics.
  • High-density PCBs with narrow pitch pattern and viaswith high-aspect ratio.
  • High-reliability and high-quality PCBs using technologies accumulated over the years.
