Abstract
Tin plating is finding increasing importance in electronic, canning and automobile industries. The sulphate and chloride formulations have many limitations. Fluoborate bath is more favourable because of its high solubility, case of deposition etc. However, the preparation of tin fluoborate is still carried out by a time consuming chemical process which yields product containing impurities much higher than the recommended standards. An electrochemical method described in this paper offers a simple, easier and quicker method for the preparation of Sn(BF4)2 with negligible impurity levels, thereby quality electrodeposits can be obtained
