The present invention provides a polycarbonate resin produced by the continuous interfacial process characterized in that after alkaline hydrolysis with sodium hydroxide, the polycarbonate resin contains an amount of 0. The hydro-blender can also include a liquid tank connected with the transport device. Further provided is a bond pad disposed, at least partially, above the metal layer. The skirt portion extends peripherally about the contoured portion. The first control switch is coupled to the first switch device for receiving the first voltage. There are large differences in the number of dark spots produced and the growth of the dark spots between a metal; e.
