发明名称 Method of making a printing wiring board
摘要 A metal cored printed wiring board and a manufacturing method therefor, in which an organic non-conductive layer will not separate from the metal core even in an environment of high temperature and high humidity since both the metal core and the organic non-conductive layer are firmly adhered. An organic non-conductive layer is formed over the metal core (e.g., of aluminum) with a metal plated layer (e.g., nickel) therebetween for protecting the metal core. A metal oxide layer is also used for enhancing adhesive force. By utilizing such a metal oxide layer, it is possible to more effectively prevent the organic non-conductive layer from separating from the plated layer (and thus the metal core). Further, the protecting metal plated layer can protect the metal core from erosion caused by contact with a strong alkali solution, etc. as may be used in a process of forming the metal oxide layer. Still further, copper plating inside the through hole can be performed easily.
