Indium 9100 - Indium Electrolyte

Indium 9100 - Indium Electrolyte

Acidic electrolyte for high speed installations

Indium 9100 is used for the deposition of pure indium coatings in high-speed systems. The electrolyte is easy to use.

Indium 9100 has been specially developed for high-speed deposition in selective coating and continuous strip lines. Strong electrolyte movement (flow, gating) enables working with high current densities and stable long-term behaviour.

The purest, deposited indium coatings can be soldered and remelted very well. This makes the process ideal for coating electronic components which can be remelted after coating.

The Indium 9100 process meets all requirements for press-fit technology.
