    摘要: In accordance with the invention, the volatility of a solder plating bath with volatile brighteners such as aldehydes has its volatility reduced by the addition of diols to the bath. The diols to the bath. The diols are advantageously 1,3 propanediol or 1,2 propanediol and are accompanied by lower molecular weight alcohols. In a preferred embodiment, a diol along with low alcohol is added to a bath comprising sulfonic acid, surfactant, grain refiner and brightening agents comprising an aromatic aldehyde and a carboxylic acid.

    摘要: A method for plating electrodes of ceramic chip electronic components includes performing electroplating in a plating bath. The plating bath contains tin (II) sulfamate, acting as a tin (II) salt; a complexing agent including at least one selected from the group consisting of citric acid, gluconic acid, pyrophosphoric acid, heptoic acid, malonic acid, malic acid, salts of these acids, and gluconic lactone; and a brightener including at least one surfactant having an HLB value of about 10 or more. The tin plating adhesion of the resulting ceramic chip electronic components can be limited to a certain level.

    摘要: The present invention provides inter alias electroplating compositions, methods for use of the compositions and products formed by the compositions. Electroplating compositions of the invention are characterized in significant part by a grain refiner/stabilizer additive comprising one or more non-aromatic compounds having null electrons that can be delocalized, e.g., an null,null unsaturated system or other conjugated system that contains a proximate electron-withdrawing group. Compositions of the invention provide enhanced grain refinement and increased stability in metal plating solutions, particularly in tin and tin alloy plating formulations.

    摘要: Methods of electrodepositing layers of tin or tin-alloys on a substrate are provided. The methods involve electrolytically treating a substrate with a solution comprising a phosphoric acid and a carboxylic acid, and electrodepositing a layer of tin or tin-alloy on a surface of the treated substrate. The methods can provide tin or tin-alloy layers having a reduced tendency to form whiskers.

    摘要: A method for providing a tin-plated wire which is free from thermal oxidation yellowing. In a tin-plated wire which comprises a core wire 1 with its surface being formed with a tin-plating layer 2, the composition of the plating is comprised of 30 to 500 wppm gallium, and tin or tin alloy that makes up the remainder thereof. With the content of Ga more than 30 wppm, thermal yellowing is able to be prevented. As too much content of Ga causes surface roughness, the content of Ga must be 500 wppm or below.
