Used DNS / DAINIPPON 80A #293760446 for sale

DNS / DAINIPPON 80A is a photoresist equipment designed for the fabrication of high-precision electronics. The system uses a chemical etching process to engrave patterns onto a conductive substrate. This engraving process involves the creating of a patterned resist layer on the substrate surface which serves as a mask for the etching of an underlying conducting material. The unit combines both light reactive and water-soluble photoresists to create the necessary etched patterns. The light reactive photoresist is an organic polymer containing a chromophore, which will absorb light of a specific wavelength and becomes soluble in an aqueous solution. The light-activated chromophore allows for the uniform deposition of the photoresist on the substrate surface. The second component, a water-soluble photoresist, is a type of polymer which can also dissolve in water. This is used to form low resistivity anisotropic pathways across the substrate. To initiate the process, patterns are first drawn on a photomask coated with two different types of photoresists. These photomasks are then placed onto the semiconductor substrate and exposed to ultraviolet light. The light activates the chromophore in the light-reactive photoresist, causing it to become soluble in an aqueous solution. The exposed substrate is then immersed in water, and the light-activated, soluble photoresist forms patterns on the surface of the substrate, allowing for fine resolution patterning. The exposed pattern is then developed by etching away the patterned resist layer with a chemical solution. This leaves a layer of underlying conductive material, forming patterns on the substrate. This allows for the formation of pathways with different resistivity characteristics, which can be utilized for the creation of high-precision circuitry. DNS 80A is a powerful and versatile photoresist machine for the fabrication of high-precision electronics. Its combination of light reactive and water-soluble photoresists allow for the creation of intricate patterns on the surface of a conductive material substrate. By using this technology to engrave patterns, high-precision circuitry can be created with different resistivity patterns and features. This tool is incredibly useful in the electronics industry and is used widely in the fabrication and design of electronic components.
