DNK MA-4201 Mask Aligner is a precision optical mask aligning tool designed for the fabrication of devices on the nanoscale level. With its high accuracy and precision capabilities, MA-4201 is ideal for obtaining smooth, defect-free edges on lithographically produced parts. Its unique design allows users to quickly and easily adjust the settings for best results, making it a cost-effective option for applications such as high density, low defect process development. DNK MA-4201 features a precision optical mask aligner that uses ultra-high power LED (Light Emitting Diode) illumination, with an exposure area of up to 4 x 2 cm. This ensures an extremely uniform illumination and allows users to accurately and precisely align their masks during fabrication. The adjustment of the optics is also simple, as the equipment is equipped with X/Y/Z universal adjustment knobs. This makes alignment as easy as possible, so that high quality parts can be quickly produced. MA-4201 mask aligner has a long service life, with a lifespan of 25000 hours. This ensures that users can rely on the device for their long-term processes. The system has an optical efficiency of up to 90%, enabling faster and more accurate processing. It also has a robust design, which is easy to maintain, and is applicable to a variety of substrates including glass, silicon, and plastic. DNK MA-4201 also has several automated features to enhance efficiency. It has an internal inspection unit, which automatically detects particle defects, and laser sensors to detect defect location. Furthermore, it also features a self-calibration machine, which re-calibrates the alignment values after each process, thus ensuring that the process is reproducible. MA-4201 mask aligner is an excellent tool for a wide range of precision fabrication processes, allowing users to quickly and accurately obtain defect-free parts with uniform edges. With its long lifespan, automated features, and robust design, the tool is a reliable and economical choice for users on a budget.
