塑料芯金属涂层颗粒 Micropearl AU

1.What is Micropearl AU?

用于电子产品和基板材料之间的导通，热传递，控制间隔等方面

2. Features

1Metal Types Lineup

We have a variety of metal types to choose from to meet your needs.

2Hardness Control

It is possible to adjust hardness and recovery rate by controlling plastic particles and metal film.

3Volume resistivity

♦Volume resistance by metal species
♦Anti-corrosion treatment effect of Ni coating
・Original anti-corrosion treatment achieves high corrosion resistance of Ni coating
  • 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.

Metal Types 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
  • 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.

3. Application examples

1Connection

  • Conduction and heat dissipation＋Uniform gap
  • Anisotropic conductivity due to uniform particle size and monodispersity
  • Improved long-term connection reliability due to the resilience of the plastic core
  • Weight reduction of materials by low specific gravity
Example 1) Terminal connection
Example 2) Conduction path formation
【Example) Terminal connection】

2Electrode Formation

  • Formation of ultra small and narrow pitch electrodes with abundant particle size and uniform particle size
  • Improvement of high frequency characteristics by low profile between boards
  • Formation of elastic electrodes with flexibility and resilience
Example 1) Narrow pitch electrode formation
【Example of electrode formation on a substrate】
Example 2) Formation of aggregate particle electrodes

3For thickness control and stress relaxation

  • Stress dispersion by tilt control
  • Reduces thermal stress due to the difference in linear expansion between parts
  • Lower elasticity and higher shear strength of the joint layer
  • Relaxation of stress in brittle material mounting
Example 1) Stress Dispersion by Tilt Control
【Tilt control effectl】
Example 2) Lower elasticity and higher shear strength
【Stress simulation】
