    For the photovoltaic / solar industry, we provide a full range of products which serve the great breadth of current research & development and production requirements. This includes versatile manual wet stations for early development of break-through silicon, CIS-thin-film, Silicon/GaAs technologies and Nanotechnology, as well as wet benches fully automated large batch processing systems for mainstream production applications. Thus, customers have the ability to enter production with the same processing technology as they developed their products on.

    Many of our innovative customer solutions for wet benches include unique fixtures required to handle substrates that are of uncommon size, shape, rigidity, weight, and/or material, or which must be compatible with physical changes that occur during the wet process. Substrates which we have designed unique solutions for include: elements of up to 3,000mm in length, lenses of 1,200 pounds in weight, crushed material of 1mm grain size and flexible metal panels of <0.007” thickness.

    Amerimade also Manufactures wet processing for Medical Device Equipment for Polishing Stents, Catheters, Micro Parts.  key: medical device equipment, Medical Devices needing polishing for stent, drug coated stents and micro machining wet benches, stripping and etching, cleaning with ultrasonic.
