The winding, climbing roads of North Derbyshire still bore traces of the year's early snowfall, with mud‐splashed, hard‐packed drifts remaining by the roadside, when Circuit World visited LeaRonal on the outskirts of Buxton in December. At 1007 feet, Buxton is one of the highest towns in England. A spa and holiday resort, it is situated in the picturesque Peak District with its characteristic rocky crags, rugged moorlands and wooded dales. Britain's first national park—the Peak District National Park—covers some 540 square miles and it is at the edge of this leisure area that LeaRonal's High Peak Laboratories facility is located.

Alloys deposited from plating solutions vary in composition with changes in solution constituents and processing parameters. With the increasing demand on miniaturisation and quality of subsequent solder joints made to plated tin‐lead alloys, it is important to ensure stable deposit composition and also to know to what extent changes in operating conditions will affect the composition. This paper examines the major causes of changes in composition of deposits plated from solutions based on fluoboric acid and organic sulphonic acid. The methods available for measuring the deposit composition are also discussed.
