Rinsing water following an electrolyte tin plating (acid electrolyte)

Tin sulfate, alkylsulfon acid, polishing agent

The rinsing water quality following tin plating is of especially great importance for further process steps like a good solderability. There must be a low conductivity to be able to ensure a clean surface of the work piece.

A continual processing of the rinsing water through the VACUDEST® vacuum distillation process makes rinsing water of the desired high quality available.

A processing of the electrolyte itself is not economically sensible because of the salt concentration.

Practical experience in continuous operation shows that a 100 % recycling and circulation process of the rinsing water leads to optimal cleaning results. Through the high quality of the distillate we receive also optimal rinsing results. With VACUDEST® WPV the reduction in fresh water costs simultaneously significantly reduces the processing costs of rinsing water.
