Sintering Copper Fine Powder


Submicron size sintered copper powder that can control the sintering temperature by surface treatment.

Application Example

It can be used for internal and external electrodes for fine wiring of laminated ceramic products.
In addition, it can be used as a bonding material or heat dissipation material that utilizes thermal conductivity better than solder.
