Used LOTUS SYSTEMS CVS/CDS #293589874 for sale

LOTUS SYSTEMS CVS/CDS is a photoresist equipment that provides a cost effective, reliable, and flexible solution for circuit manufacturing. Specifically, it is a resist coating system that is composed of materials that are easy to process and which have high resolution and stability. The unit combines chemistry and coating technology to deliver good process repeatability. The main components of the photoresist machine are the LOTUS Resist Coating Tool (RCS), the LOTUS Coating Dispenser Asset (CDS), and the LOTUS Photomask Alignment Model (PAS). The RCS is responsible for providing a uniform and reliable coat on copper or other substrates. It has two major parts: the casting head, which delivers the photoresist material at a consistent rate and is monitored for accuracy; and the two tracking arms, which move over the substrate surface and maintain the uniform coating thickness. The CDS is responsible for providing accurate and repeatable quantities of the photoresist material. It features an automated dispenser that monitors the feed rate, the temperature of the material, and the level of the reservoir. This ensures consistent amounts of the material being applied to substrates. Finally, the PAS works in conjunction with the CDS and RCS, by aligning the photomask over the substrate, so that the patterns of the photoresist on the substrate align with the patterns of the photomask. This alignment is achieved through precise placement and surface reading of the photomask. The photoresist materials used in LOTUS SYSTEMS CVS/CDS are typically polymeric materials such as polymethyl methacrylate (PMMA) and polyethoxyvinylacetate (PEVA). These polymers are often chosen for their stable electrical properties and ability to be easily modified for customer needs. The photoresist also features a high photo-sensitivity, which means that it can be easily exposed to a controlled ultraviolet light source for patterning. LOTUS SYSTEMS CVS/CDS provides an easily programmable and user-friendly way for circuit fabrication. It is a stable and consistent resist coating equipment that offers fast production speeds, high resolution, and excellent photomask alignment accuracy. The system is also cost effective and requires minimal operator training and maintenance.
