Product Information

Electronic Materials Our thin copper foil manufactured by using the world’s first electroless chemical copper plating process has versatile applications including EMI shielding, FCCL, and radiating film.

Ultra-thin Copper Foil

  • About 2um to 6um ultra-thin copper foil that becomes the raw material for EMI shielding and FCCL.
  • The world’s first copper foil manufactured by electroless chemical copper plating process

EMI Shielding Sheet

  • Copper foil form that consists of aluminum carrier and copper
  • The electronic material with high expectations of growth due to its electromagnetic shielding and radiating effects

PET CCL

  • FCCL manufactured by using our copper foil
  • Expected to grow following the emergence of the “Light, Thin, Short, and Small” trend

RTR Manufacturing Facility

  • The manufacturing facility of copper foil that applies chemicals on the basic material while wrapping it around the rotating roll

Foam thin copper foil for 5G high speed transmission EMI shielding, low roughness, and porosity

  • Shape

  • Characteristics of copper foil

    • YMT’s Foam Cu Foil boasts its remarkable shielding effects as well as low surface roughness (Ra) in the high frequency range, thereby reducing signal loss and preserving outstanding transmission features in application to high speed transmission EMI materials.

  • Nano-scan Image

  • Overview of materials for high speed transmission EMI shielding

    • When the electromagnetic waves occurred in PCB circuit break through C/L and move toward the Y-axis, the refraction and reflection in EMI conductive glue and Shield Cu reduces the waves, emits noise toward the X-axis, and releases it throughhe conductive glue connected to the grounding exposed.
