    LED chip and the board
  • Gap control materials between a power semiconductor and the board
    Material that control gap between
    power semiconductor and the board

3. Manufacturing process

All processes from substrate particles to plating are manufactured by our company

  • Manufacturing process

4. Product structure(by TEM)

TEM

  • Product structure(by TEM)
  • Achieve stable conductivity with no variation in resistance by plating uniformy to each particles

Anisotropic conductive composite

By heating and pressurizing, it is used for a conductive material that has electrical conductivity in the film thickness direction and insulative electrical anisotropy in the plane direction.

5. Mechanical Properties

1Compressed conductivity(Micropearl AU,7.25µm )

  • Compressed conductivity(Micropearl AU,7.25μm )
  • Achieve stable conductivity with no variation in resistance by plating uniformy to each particles

2Object resistance value

  • Object resistance value
Cu / Ag composite plating particles can reduce powder resistance value by 90% for Ni plating particles

3Hard・Flexible resin core particle

  • Hard resin core particle
    Hard resin core particle
  • Flexible resin core particle
    Flexible resin core particle
The flatness of particles can be controled due to the hardness of the resin core particles, during pressure mounting
