Conductive Fabric Tape

Issues Application Examples Effect
Application Areas Shield electrical/magnetic waves leaking through circuit components and wiring or apply grounding path formation/step compensation

Conductive Fabric Single-sided, Double-sided Tape

SSC30D : Step Compensation, Grounding

SDC80H : FPCB Fixed, Grounding
Solution
Technical information
  • Ultra-thin conductive fiber tape with a thickness of 20um of conductive fiber and an overall thickness of 30μm
  • Normally, conductive fibers have good breathability, so when making single-sided tapes using conductive adhesives, it is difficult to create single-sided tapes due to the fluidity of conductive adhesives.

Conductive Black Tape

Issues Application Examples Effect
Application Areas
  • Poor touch performance
  • EMI Noise leakage, light leakage, thickness, weight problems, etc.
  • Touch performance stabilization
  • EMI Noise Suppression / Light Leakage Prevention
  • Conductive Black Tapes thinning and lighter LCM module
  • High performance of IC chip causes EMI noise
  • SUS Cover Shield limits EMI noise suppression
  • SUS Cover Shield Top Conductive Black Tapes to resolve EMI Noise issues
  • Insufficient concealment power
  • Color differences with surrounding black utensils and devices
  • Closes pinholes in fibers to enhance concealment
  • Black color gives unity
Technical information
  • Fewer curl phenomenon and excellent workability.
  • Realize excellent resistance stability and excellent shielding performance.
  • Flexible, excellent adhesion, can be applied to various shapes.

Conductive Cushion Tape

Issues Application Examples Effect
Application Areas
  • EMI noise leakage and ESD problems between instruments and appliances
  • Conductive cushion tape between metal appliances to solve EMI/ESD (electrostatic) problems
  • Disconnect problem caused by connector step at circuit connection site
Technical information
  • 0.3T or less thin film conductive cushion product
    (Conventional conductive cushion tape: between 0.3T and 6.5T)
  • Conductive fabric attached to the surface makes it easy to attach a protective film.
    (The existing conductive cushion tape has a rough surface, making it difficult to attach a protective film)

Electromagnetic Wave Absorber

Issues Application Examples Effect
Application Areas
  • CPU / MPU / PM IC /RF Chip EMI generation
  • Absorber applied instead of SUS Cover Shield or on top of EMI Noise issue
  • Multi-layer absorber has excellent EMI noise suppression effect of IC chip
Technical information
  • Roll type production has excellent workability and price competitiveness during the process.
  • Absorber Sheet + Cu Tape multi-layer structure has excellent electromagnetic noise shielding/absorption function, and no dust is generated during grinding and cutting.
  • Excellent EMI absorption characteristics in a wide frequency band.
