Electro-less copper plating, as a method of providing good electric conductivity on ceramic or polymer surfaces, is widely used in many industrial fields, such as a semiconductor circuit, a printed circuit board (PCB) and various composite materials. In general, a semiconductor circuit or a printed circuit board (PCB) is preferred a copper plating layer having a low surface roughness. On the other hand, in order to obtain a high density sintered body, a copper plating layer of high surface roughness is preferred. Therefore, it is necessary to adjust the surface roughness of the plating layer for the plating purpose of each material. In this study, we examined the surface roughness of the Cu plating layer by adjusting the plating conditions such as the initial surface roughness of material, the plating rate and the plating time affecting the surface roughness of the electro-less Cu plating layer.
SiC/Cu matrix composites are candidate materials for heat sinks due to their high thermal conductivity and low coefficient of thermal expansion. And Using the continuous SiC fiber as a reinforcement reduces the vol% of SiC fiber than using SiC powder. Therefore, SiC fiber reinforced Cu matrix composite is a good heat sink material having a high thermal properties. But, the wettability of carbon on copper is weak. In order to solve these problem, SiC/Cu composite was fabricated by electro & electroless plating process. Results show that SiC fiber reinforced composite fabricated by electro-less plating has a good thermal properties than SiC powder reinforced composite.
