摘要： A process for applying a metal coating to a non-conductive substrate without an electroless coating is disclosed. The process includes the step of: a. contacting said substrate with an activator comprising a noble metal/Group IVA metal sol to obtain a treated substrate; b. contacting said treated substrate with a self accelerating and replenishing immersion metal composition comprising a solution of (i) a soluble metal salt whose metal is more noble than said Group IVA metal, (ii) a Group IA metal hydroxide, (iii) a complexing agent comprising an organic material having a cumulative formation constant log K of from about 0.73 to about 21.95 for an ion of the metal of said metal salt. The Group IVA metal is employed in a stoichiometric excess compared to the noble metal, the excess Group IVA metal being in its lowest oxidation state. Self accelerating and replenishing non-formaldehyde immersion metal compositions are also disclosed. The composition is used in a two step process to electrolytically coat a nonconductive substrate. In the first step the conductivity of the substrate is increased by applying the composition to it. In the second step, the substrate treated with the composition is electrolytically coated with a metal.

摘要： A fluid delivery method is provided wherein either liquid or gaseous fluid is provided from fluid dispenser manifolds, via nozzle plates associated therewith, on each side of a path of travel of articles being treated by the fluid, and wherein nozzle openings in a nozzle plates cooperate with transverse groove(s) to provide a screen flow of fluid extending transversely of the path of travel of articles, and directed toward the articles. In the case of the fluid being a liquid, the nozzle openings provide cylindrical filament-like columns of liquid which are rendered by the associated grooves into generally flat, transversely disposed screen spray of liquid. In the case of the fluid being a gas, the nozzle openings and transverse grooves cooperate to deliver the gas in transversely spaced apart, transverse, planar zones of gas directed toward the path of article travel.In the case of liquid flow, the openings are generally cylindrical, and in the case of gas flow the openings are generally spaced-apart slotted holes. In the cases of both liquid and gas fluids, one of the grooves and/or nozzles are directed upstream relative to the path of article flow. Various adjustments are provided for adjusting the positions of the nozzle plates relative to the path of flow.The nozzle plate has a removable portion, for ease of cleaning and the like, that contains the nozzle orifices, sealing connected to the nozzle base section. The transverse groove that connects the line of orifices can have its center line varied from the center line of the orifices, in the direction of the longitudinal path, and/or the groove can have its angular orientation varied such that the path of flow of fluid discharged can be at an angle other than 90.degree. to the discharge surface of the nozzle plate.

摘要： An electrogalvanizing process and composition are disclosed for reducing high current density dendrite (HCD) formation and edge burn and controlling high current density roughness, grain size and orientation of a zinc coating obtained from a zinc halide aqueous acidic electrogalvanic coating bath. A low molecular weight polyoxyalkylene glycol homopolymer or copolymer based on 3 to about 4 carbon atom alkylene oxides as a grain refining agent in combination with a sulfonated condensation product of naphthalene and formaldehyde which is used as an antidendritic agent. A glycol compound comprising a high molecular weight polyoxyalkylene glycol homopolymer or copolymer, a depolarizer such as an aniline compound, and a carbamate compound comprising a di-lower alkyl dithio carbamyl lower alkyl sulfonic acid may also be used, optionally in combination with an aldehyde and/or a grain refining agent such as a low molecular weight polyoxyalkylene glycol homopolymer or copolymer and/or an antidendritic agent comprising a sulfonated condensation product of naphthalene and formaldehyde. HCD zinc coatings applied according to the process described herein will be smoother when using a sulfonated naphthalene formaldehyde antidendritic agent and a low molecular weight ethylene oxide polymer grain refining agent by increasing the antidendritic agent to an amount greater than the grain refining agent. A boron oxide composition can be used to further reduce HCD burn and a lignin compound to increase brightness.

摘要： Apparatus for treating printed circuit boards or other items is provided, wherein a drying apparatus is specifically provided, generally for use as part of a cleaning or other treatment apparatus, but which can be separately provided, if desired. The drying apparatus employs preferably warm air discharge tubes, for drying items of varying thicknesses, and/or that have varying thicknesses of components mounted thereon. Generally, the printed circuit or other items are carried through the apparatus between upper and lower foraminous conveyor belts, with one of the belts, conforming to the varying thicknesses of the items, or components carried by the items. While some of the air discharge tubes may be stationarily mounted, at least some of them are pivotally mounted, such that their discharge opening zones can slide along and conform to variations in thickness. The discharge tube will pivot in response to the varying thicknesses. The pivotal motion of the tube may be provided with a means for balancing the same.
