Just a thought.

If I remember correctly, very thin foils are provided on backing materials. They
are very uniformly coated with an adhesive. In contact to another substrate they
adhere with the adhesive. You then peel off the backing. I think I remember
seeing them used in art projects. You just need one that is silver without a
coating. For prototyping it might work.

Subject: [mems-talk] Spacer material

Hi everyone,

Could you suggest me a spacer material for separating two (horizontal) glass
plates? The spacer should have a thickness of 100 µm, but more importantly, the
thickness tolerance should be as low as possible. Also, the spacer needs to be
fixed manually on the glass plate: it cannot be processed on the glass plate but
it has to be attached afterwards.

I thought of using a thin metal sheet and then glue it to the glass plate, but I
don't know if it will be the best way.

Any help or ideas are welcome!

Nicolas
