Our Lead(Pb)Free Solder

We, Fuji Electric Group aim at contribution to the conservation of environmental.

Dear Sirs,
How to keep and transfer verdurous and inestimable nature for posterity?
We think conservation of the environment is very important part more and more for behavior of enterprises.

It is typical example of how to contribute to the conservation of the environment that enterprises try to apply lead (Pb) free solder to their product at the earliest possible opportunity in order to deal with WEEE & RoHS instruction in Europe.

As part of applying lead (Pb) free solder measures, we developed original composition lead (Pb) free solder and have been applied this lead (Pb) free solder in our company in order for us to aim positively at dealing with environmental problems at inside and out side of the country.

We think this lead (Pb) free solder have a feature such as excellent solderbility and thermal stability and decreasing of the dross (oxidation refuse of Tin) by suppressing oxidation as a result of adding Ni (Nickel) and Ge (Germanium) in to the Sn-Ag-Cu (Tin-Silver-Copper) alloy and the Sn-Bi (Tin-Bismuth) alloy.
We acquired the Sn-Ag-Cu (Tin-Silver-Copper) system lead (Pb) free solder patents in United States, Japan, and Germany.

We, Fuji Electric group do not think about use our original composition lead (Pb) free solder in our own company.
To contribute to the conservation of the environment with the other enterprises as worldwide, we have been license our original composition lead (Pb) free solder patents for value against other enterprises to apply our original composition lead (Pb) free solder.
For license of lead (Pb) free solder patents, please refer to "LICENSE (with Licensee List)".

Also, at the time of compensatory release of these our lead free solder　patents, we endeavor with our licensee to maintain our intellectual property　right value by endeavor to remove of infringement behavior.
