Used ESA SRD-3000 #9285370 for sale

ESA SRD-3000 photoresist equipment is an advanced photolithography system used to build modern electronics. Specifically, this unit uses a light-blocking material known as photoresist, which consists of a polymeric matrix and light-sensitive chemicals, to produce extremely thin layers of metal films needed for circuit printing. Photoresist materials are applied to a substrate using a spin-coating process. This process involves a spin-coater, which is an automated machine used to uniformly apply a coating on a substrate when rotated at a constant speed. The spin-coater applies the photoresist, which is a solution of liquid polymers and photosensitive chemicals, to the substrate. The material then slowly hardens as it dries. Once the photoresist is applied, the substrate is then exposed to a pattern of light (which is a process known as imaging) in order to activate the photosensitive chemicals within the photoresist. The imaging step is managed by a laser imaging machine incorporated into SRD-3000 tool. This asset uses lasers to precisely project an image onto the photoresist. The intensity and duration of the light exposure will determine which parts of the photoresist will be hardened and which remain soluble. Finally, the remaining photoresist (the parts not exposed to light) is then washed away to reveal a pattern of metal lines on the substrate. The remaining photoresist layer acts as an insulation layer that protects the underlying circuit and metal layers beneath it during further processing steps such as etching, plating, and play tape attachment. In conclusion, ESA SRD-3000 photoresist model is a highly advanced photolithography equipment that allows for thin metal lines to be created on a substrate, enabling the production of high quality modern electronics. This system utilizes lasers to precisely project a pattern of light onto the photoresist, which then activate photosensitive chemicals to harden specific areas of the photoresist. After the remaining photoresist is washed away, the pattern of metal lines remain clearly visible and usable for further production processes.
