water-resistance

◆PET has low moisture absorption (PET: 0.1-0.2% vs polyimide: 2.0-3.0% )
  • By adopting a waterproof soldermask in the wiring layer, it corresponds to ipx6 degrees.
  • Reduction of man-hours for waterproofing cables with sealing materials, taping, etc.
◆Target area of application
  • Bath and toiletry products
  • Products around the kitchen
  • Temperature and humidity sensor
      ←Contributes to improving measurement accuracy of implemented sensors
  • Products that operate and store at 0 degrees Celsius or less
      ←When the moisture-absorbing substrate becomes an environment below freezing, moisture freezes and expands, impairing the flexibility of the FPC, effective for breakage
