The cleaning solution has an alkaline pH, which is preferably from about 8 to about 11.5 and consists essentially of at least one low foaming surfactant in a concentration of from about 0.005% to about 40% w/w of the total solution, at least one active oxygen releasing compound in an amount effective to produce a hydrogen peroxide concentration of from about 0.005% to about 50% w/w of the total solution, at least one builder in a concentration of from about 0.001% to about 50% w/w of the total solution, and at least one diluent selected from the group consisting of water, deionized water, and mixtures thereof.Type: GrantFiled: July 12, 2002Date of Patent: February 3, 2004Assignee: Virox Technologies, Inc.Inventors: Jose A. Ramirez, Nancy M. A. Sullivan

Patent number: 6666987Abstract: A liquid etchant and a method for roughening a copper surface each capable of providing copper with a roughened surface increased in acid resistance regardless of a chlorine ion in a short period of time, to thereby ensure firm adhesion between a copper conductive pattern and an outer layer material during manufacturing of a printed circuit board, resulting in the manufacturing being highly simplified. The liquid etchant includes a main component containing an oxo acid such as sulfuric acid and a peroxide such as hydrogen peroxide. Also, the liquid etchant includes an auxiliary component containing a tetrazole such as 5-aminotetrazole or the like, or a 1,2,3-azole. The liquid etchant permits a copper surface to be roughened in an acicular manner.Type: GrantFiled: June 8, 1999Date of Patent: December 23, 2003Assignee: Ebara Densan Ltd.Inventors: Yoshihiko Morikawa, Kazunori Senbiki, Nobuhiro Yamazaki

Patent number: 4941185Abstract: A method and apparatus for processing a first (e.g. half-tone) image constituted by a second (e.g. continuous tone) image convolved with a periodic (screen) function, to produce the second image is described. The invention is particularly suited to handling digitally represented half-tone images. The apparatus comprises a microcomputer (17) for determining digital data defining a frequency filter characteristic adapted to suppress the frequency or frequencies of the periodic function. A fast Fourier transform circuit (11) transforms the image data into the frequency domain and a multiplier (12) multiplies the transformed data by the frequency characteristic stored in a store (13). The resultant multiplied data is inversely transformed back into the image of spatial domain by a fast Fourier transform circuit (14) to generate the second image.Type: GrantFiled: October 6, 1988Date of Patent: July 10, 1990Assignee: Crosfield ElectronicsInventor: Alastair Reed
