High-temperature Sintering Cu Fine Powder

Summary

We provide submicron- (nano-)size copper powders by utilizing the powder manufacturing technology, sintering and firing technology, and surface treatment technology that we have cultivated over many years in sputtering targets.
Our original surface treatment controls sintering properties and oxidation prevention while providing excellent dispersibility. In addition, by optimizing the sintering conditions, low resistance (high thermal conductivity) and high shear strength can be obtained.
Unlike silver, copper powder does not have problems such as migration, and is highly reliable (for thermal cycle and power cycle) in bonding.

Application Example

  • A submicron-sized Cu powder that can be sintered at high temperatures and considered for simultaneous firing with ceramics.
  • JX Cu powder can be considered for applications that require high-temperature sintering and fine wiring.
