Used PVA TEPLA 650 #9246396 for sale

PVA TEPLA 650 is a negative photoresist equipment used in the production of printed circuit boards (PCBs) and semiconductor devices. It is a dry-film photoresist system composed of a photosensitive polymer blend which is deposited onto the substrate via a roller coater. This photoresist layer is then exposed to light and chemically developed to form resists patterns that are used as masks for etching and shaping the substrate. The TEPLA 650 unit is an all-in-one solution, and is designed to provide superior resolution, adhesion, and line width profiles for a broad range of applications.The sensitization of this machine is accomplished through the addition of a riboflavin promoter, resulting in optimal adhesion to the substrate and enhanced resolution at lowered exposure energies. It also offers increased etching resistance, exhibiting superior wet and dry etch profiles. TEPLA PVA TEPLA 650 is able to accurately reproduce ultra-fine line and pad structures, even down to 0.009 mm or 0.12 mils minimum in size. This allows for very precise designs to be produced, allowing for the manufacture of complex and intricate circuits which would be difficult to produce with other photoresist systems. It can also be used to create multi-layer devices with excellent planarity for high interconnect density in applications. The TEPLA 650 tool features excellent post-exposure and post-bake adherence, allowing it to work as a mask for the etching process for a wide range of processes, including UV reactive, organic, and metal-based etchants. Furthermore, with the inclusion of an alkali-soluble novolak polymer, this photoresist exhibits excellent lift-off properties. It can be easily removed after the etching process, eliminating any risk of undercutting or residues being left behind. Overall, PVA TEPLA 650 is a reliable negative photoresist asset that provides superior resolution and line width profiles for a wide range of applications. It offers excellent adherence, etch resistance, and lift-off properties, facilitating the manufacture of intricate and complex circuit designs.
