    Abstract: PURPOSE: To strengthen bonding strength of Cu track by removing a coating after opening a hole on two-sides Cu coated substrate, submerging it in an active bath for activation, further, after sensitizing, forming Ni, Co, Mn, Ni-Fe, or Ni-Co layer of 0.05-2.0μm, and then forming a conductive pattern on a Cu layer on it. CONSTITUTION: A copper-coated epoxy resin plate is etched for removing a Cu coating, then it is activated in a solution of 4-cyclohexanone-1.2-anhydrous dicarboxylic acid-palladium chloride, CH2 Cl2 , tetrabutyltitasnate, and then dimethylamineborane-sensitized for nickel-plating. A copper layer of 2μm thickness is stuck on a nickel layer of about 0.2μm in a chemical copper bath, and then annealed at 150 deg.C. Thereby, a conductive metal coating of good adhesive property is obtained, and on it, a conductive pattern is formed by semi-addition- difference etching.
