Consistent materials

What are the composition materials from 1 to 4 on the drawing below?

1. can be a photoresist (preferably positive), but also a rubber lip, Capton tape, solder resist or any other type of masking to expose the areas to be coated with NanoWiring. The masking material depends on the tolerance to be achieved.

2. the carrier material can be any material, e.g. plastic, glass, ceramic, steel, aluminium, semiconductor
semiconductor material, copper, brass, etc., as long as there is an adhesion and a seed layer that can be industrially produced.

3. it is a special sponge with a special porosity layer. The porosity layer is filled with metal during the galvanic process.
Process filled with metal.

4. the materials currently used are copper, silver, gold, nickel, zinc, platinum, ...

What is the material used on the special sponge for the production of NanoWiring? Is it metal or an organic substance?

The sponge with its porosity layer consists of an organic material

How do you insert a special sponge that has a µ-level hole into the base material? Or do you insert this special sponge into the base material and then create the µ-level hole?

The porosity layer of the sponge is created by a special process.

Do you wash away this sponge when stripping? Or do you have another method to remove sponge from substrates?

To reduce the effort we remove a part of the sponge material mechanically, except for the area of the porosity layer.
The area of the porosity layer is then removed wet-chemically using cyclopentanone. This is done in an automated
multi-stage washing process, so that it is removed without residue.
