Used OKK SRD #9144785 for sale

OKK SRD is a modulated type positive photoresist equipment that is used for imaging and developing patterns on a substrate surface. Photoresist systems are used to create patterns on substrates for a variety of applications, such as printed circuits for electronics and photolithography. SRD system is composed of three parts: the photoresist, the light source, and the developing solution. The photoresist is a light-sensitive material applied to a substrate surface. When this material is exposed to light from the light source, certain areas of the photoresist will undergo a chemical reaction that leaves the material either soluble or insoluble in a liquid developer solution. This is known as photolithography. The light source of OKK SRD unit is a modulated light, which is comprised of light that is periodically increasing and decreasing in intensity. By varying the intensity of the light, specific areas of the photoresist become affected and those areas can then be easily removed with the developer solution. The advantage of this machine is that it is less time-consuming and costly than using a single-level light source. The developing solution in SRD tool contains an anionic or cationic developing agent. Depending on the type of developing agent used, the areas of the photoresist that were exposed to the light will become either more or less soluble. This allows users to easily remove unwanted photoresist material from the substrate surface. In conclusion, OKK SRD asset is an innovative photoresist model. It allows users to quickly and cost-effectively produce patterns on substrates using a modulated light source and anionic or cationic developer solution. As a result, this equipment is widely used for producing microelectronic devices and photolithography processes.
