      Conductive copper paste 

  S5000 is a newly developed low temperature curable Copper paste which is directly solderable on its film surface.In the former polymer paste,solderability has been incompatible with electrical conductivity and eletroless-plating has been additionally required while circuit processing.In order to establish a perfect dir additive process.Which is directly solderable and has excellent conductivity.

 S-5000 makes it possible to realize such things as follows:

..New circuit designs which have never been attainable before.

..Substitution for etched Copper foil wet process

..Substitution for cermet thick film firing process

And further more development can be expected by applying this new s-5000.
