Product Description Autocatalytic Nickel Plating Electroless Ni Plated Alumina Ceramic Substrate PCBProduct IntroductionWhy Metallization is Necessary on the Surface of CeramicSubstrates?The ceramic substrate has better electrical function, thermalconductivity and insulation after metallization.What are the Methods of Metallization of Ceramic Substrates?Ceramic substrate metallization is to firmly adhere a layer of metal filmon the surface of ceramic substrate to realize the welding betweenceramic and metal. There are many ceramic substrate metallizationprocesses such as Mo-Mn method, electroless nickel plating method,silver firing method, and Direct Bonded Copper (DBC) method. What is Electroless Nickel Plating Method?The process flow of electroless nickel plating is shown in the pictureon the left.1. Surface treatment: to purify and roughen the surface of theceramic substrate;2. Sensitization: the process of evenly adsorbing a layer of SnCl2 onthe surface of the ceramic substrate;3. Activation: immerse the sensitized ceramic substrate in theactivation solution to deposit a layer of Pd on its surface (forming acatalyst layer that induces nickel deposition reaction);4. Pre-plating: the process of soaking the ceramic substrate in thepre-plating solution to form a thin and uniform metal nickel film on thesurface of the ceramic substrate, and cleaning off the excessactivation solution;5. Final plating: form a uniform Ni-P alloy layer with a certainthickness on the surface of the ceramic substrate;6. Heat treatment: make the Ni-P alloy layer dense, increase thedegree of crystallization, and increase the bonding strength with thesubstrate.
