※Micropearl AU values are for a resin core of 10 μm
※The above is not a standard value. The above values are not standard values.

4Specific gravity

As it has lower specific gravity than metal powder, it prevents sedimentation in the binder and reduces the weight of the material.

Status specific gravity
Ni Ni metal powder 8.9
Micropearl AU Ni-coated 1.9
Au Au metal powder 19.3
Micropearl AU Au coating 2.2
Cu Cu metal powder 8.9
Micropearl AU with Cu coating 2.1
Ag Ag metal powder 10.5
Micropearl AU with Ag coating 2.7

3. Application examples

1Connection

  1. Conduction and heat dissipation + Uniform gap
  2. Anisotropic conductivity due to uniform particle size and monodispersity
  3. Improved long-term connection reliability due to the resilience of the plastic core
  4. Weight reduction of materials by low specific gravity

2Electrode Formation

  1. Formation of ultra small and narrow pitch electrodes with abundant particle size and uniform particle size
  2. Improvement of high frequency characteristics by low profile between boards
  3. Formation of elastic electrodes with flexibility and resilience
  • Example 1)

3For thickness control and stress relaxation

  1. Stress dispersion by tilt control
  2. Reduces thermal stress due to the difference in linear expansion between parts
  3. Lower elasticity and higher shear strength of the joint layer
  4. Relaxation of stress in brittle material mounting
