Used SOKUDO DT-3000 #9389814 for sale

SOKUDO DT-3000 is a photoresist equipment designed specifically for use in the production of electronic circuits and other related components. This system utilizes a sophisticated three-stage photoresist exposure process to achieve high precision and extremely accurate registration of the pattern layers. The unit begins with an electrolyte that is mixed with organic solvents. The organic solvents are chosen for their properties, such as low volatility and good electrical conductivity. The mixed electrolyte is spread on the photosensitive substrate, such as an epoxy or polyimide surface. The surface is then exposed to three different wavelengths of light (UV, visible and near-infrared). The photoresist is resistant to the UV light, highly sensitive to the visible light and permeable to the near-infrared light. When the UV radiation strikes the photoresist and reaches the polymer matrix, it starts to form cross-links in between the polymeric chains. The visible light wraps around the polymeric chains, creating a free radical which bonds to the polymer backbone, while the near-infrared light allows diffusion of the reaction products in the matrix until the photoresist is completely cured. After being exposed to the three different light sources, the photoresist is developed in a developer solution. The developer solution specifically targets the polymer chains, removing the chains exposed to UV and visible light, resulting in an exact copy of the desired circuit pattern. Once the developer solution is removed, the substrate is then ready for the next step in the process. The photoresist machine provides high precision, accuracy and repeatability making it ideal for production of the most intricate electronic components and circuits. The tool can also be used for various other applications such as resist printing and surface coating. DT-3000 is fast, efficient, reliable and innovative, making it the perfect choice for any production environment.
