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. They have a constantly low contact resistance. 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.
