Used USHIO UMA-802-HC551NC #293749191 for sale

USHIO UMA-802-HC551NC is a high-precision exposure equipment widely used for a variety of applications in the semiconductor and electronics industry. The system is ideal for accurately and consistently exposing photosensitive materials and integrated circuit designs to UV light. UMA-802-HC551NC exposes photosensitive materials in three different ways: direct irradiation, stepped irradiation, and mask irradiation. The unit's key features include exact and repeatable exposure, user-friendly operations, compact and robust design, and long-term reliability. This machine consists of a three-vector (X-Y-Z) motion stage that can be used to transfer parts when needed, different optical paths consisting of a double condenser lens, an array of light sources such as mercury, metal halide, and LED lamps, and a vacuum mechanism for fixing parts on the transfer table to ensure uniform irradiation. Other components of the tool include PC-based software to control the exposure parameters, UV detection and analysis unit to measure beam intensity and divergence angle, and a scanning asset to control shutter movement. USHIO UMA-802-HC551NC uses a two-lens optical model to produce high-intensity uniform light to expose the part. It is equipped with a wide range of adjustable parameters, such as additional magnifying lenses, shutter opening, light sources, and exposure times (1-12 seconds), which allows users to achieve an effective exposure result. In addition, the equipment offers high accuracy and stability, with an accuracy of 3 microns and a repeatability of 0.5 micron. It also comes with a dust collector and a humidity and temperature control system to prevent contamination. Overall, UMA-802-HC551NC is an excellent choice for exposing photosensitive materials and integrated circuit designs in the semiconductor and electronics industries due to its superior accuracy, repeatability, user-friendly operation, long-term reliability, and wide range of adjustable parameters.
