“…Tin-copper alloys 14,15,18,19 were deposited under controlled flow condition, using potentiostatic technique (via the rotating cylinder electrode) and galvanostatic technique (via the rotating cylinder Hull cell). The rotating cylinder Hull cell was used to deposit a controlled non-uniform distribution of tin-copper alloys along the cathode length.…”

Tin and tin-alloy deposits enjoy many applications in the electronics, tribology and engineering industries with potential applications as electrodes for lithium batteries and as electrocatalyst coatings. Methanesulfonic acid has become a favoured electrolyte due to its environmental benefits and ability to offer a vehicle for many metal alloy, conductive polymer and composite coatings. A number of emergent uses require less common compositions or structures of alloy, polymer or composite deposits. This paper concisely provides diverse examples of modern tin-containing deposits from aqueous methanesulfonic acid, including Sn-Cu alloys having a very wide composition together with a wide range of colours (golden yellow-dark brown) and surface finishes, a Sn-Cu composite deposit containing ceramic, protonated titanium oxide nanotubes for batteries, a tincopper-bismuth ternary alloy and tin deposits supported on an inert reticulated vitreous carbon or carbon felt substrate to provide a porous, 3-dimensional tin surface for electrocatalysis and batteries.The importance of controlled current distribution and electrode/electrolyte movement are illustrated by the use of the rotating disc electrode (RDE), rotating cylinder electrode (RCE) and rotating cylinder Hull (RCH) cell.

“…Therefore, in this work, we investigated the degradation mechanism of the MSA based electroplating bath used for SnAg alloy electrodeposition. Since the electroplating bath for SnAg alloy contains several types of organic additives and two or more dissolved metal salts in the background electrolyte solution, 10,25 we rst examined the degradation behavior of the electrolytes before and aer accelerated aging to mimic the effects of long term operation, and then the effects of the degradation of the electrolyte on the properties of the Sn-Ag solder were investigated. Lastly, a correlation between the collapsing failure of the Sn-Ag alloy solder and the degradation mechanism of the electroplating bath was suggested based on the results.…”

The present study investigates the degradation mechanism of a methanesulfonic acid (MSA) based electroplating bath used for the electrodeposition of Sn-Ag alloy solder bumps, and its effects on the microstructure of the solder and on the collapse failure of flip-chip solder bumps. To examine the degradation behavior of the electroplating bath, a degraded electrolyte is prepared by accelerated aging treatment. In the presence of dissolved oxygen and Ag + ions in the electrolyte, the chemical oxidation of

“…12 The acid has been used as a green electrolyte in the surface finishing industry and in flow batteries. Examples include cathodic deposition of metals, 13 alloys, 14 anodising of lightweight metals 11 anodic deposition of metal oxides 15 and anodic oxidation of environmental organic contaminants. 16 Here, we report the anodic electrodeposition of polypyrrole from methanesulphonic acid and show that the methanesulphonate anions could be directly doped into the polypyrrole during polymerisation leading to a conductive, oxidised film.…”

1Freely-standing and flexible films (0.075 to 9 mm in thickness) of electrically conducting polypyrrole were synthesised via anodic electrodeposition onto a stainless steel substrate from methanesulphonic acid under stirred conditions at 295 K. Cyclic voltammetry was used to study the effect of pyrrole monomer concentration (0.01 to 1.0 mol dm 23) and methanesulphonic acid level (1.0 to 6.0 mol dm 23 ) on the formation of polypyrrole films. The films were prepared for deposition times of 30-240 s at constant current densities of 1 to 15 mA cm 22. The ionic conductivity of freely-standing polypyrrole membranes in aqueous methanesulphonic acid was studied. Scanning electron microscopy was used to image the surface microstructure. The polypyrrole films, which were prepared in the oxidised (methanesulphonate doped), conductive state, showed an ionic area resistance as low as 10 ohm cm 2 . The films were readily doped with the methanesulphonate anion and the membrane ionic conductivity was dependent on the electrolyte composition used for their deposition. In the presence of anodic oxygen evolution, the films showed a 'template-free' porosity due to film growth around the bubbles.
