IPC: H05K3/18
Filed: 1991-12-17
Abstract: PURPOSE:To prevent passivation of a plated layer, and to improve the close contactness between plated layers by a method wherein the plated surface is treated with a specific aqueous solution while each non-electrolytic plating treatment is being conducted. CONSTITUTION:In the printed-wiring-board manufacturing method in which a non-electrolytic plating treatment is conducted by dividing it into two or more times, the surface of plating is treated by the aqueous solution of pH 2 to 7, containing a cyanic compound, between each non-electrolytic treatment. When the aqueous solutions, pH is lower than 2, hydrogen cyanide is generated, and when the pH is higher than 8, the degree of removing action of an oxide film is decreased. As the cyanic compound has a strong chelate action with metal, the grown oxide film can be removed by treating the surface with the above-mentioned aqueous solution after a strike plating operation is finished. Also, after treatment, the cyanic compound is brought into the state wherein it is adsorbed to the plated layer, an oxide film is not grown even when the plated layer is exposed to atmospheric air before the plating work to be followed is conducted.

Filed: 1996-12-17
Abstract: PROBLEM TO BE SOLVED: To excellently remove image forming material from an image holding body and to simplify the constitution of a device by removing the image forming material from the image holding body by using a cutting tool member having specified surface roughness. SOLUTION: In this device for removing the image forming material from the image holding body 10, which removes the image forming material 12 adhering to the image holding body 10, the cutting tool member 40 whose surface roughness at a cutting contact part having the possibility of coming in contact with the surface of the image holding body is equal to the surface roughness of the image holding body 10 is used. By removing the image forming material 12 from the image holding body 10 by using the member 40, the constitution is simplified in this device differently from the device for removing the image forming material by using a peeling member.  Since the surface roughness at the cutting contact part of the member 40 having the possibility of coming in contact with the surface of the image holding body is equal to the surface roughness of the image holding body 10, the surface state of the image holding body 10 is maintained to be nearly equal to that in an unused state even though the removal of the image forming material 12 and the formation of an image are repeated.
