Used KARL SUSS / MICROTEC MA 4 #293794891 for sale

KARL SUSS / MICROTEC MA 4 is a mask aligner that has become increasingly popular for use in the electronic components industry. This device is used to produce precise overlapping of electronic devices on a silicon substrates. MICROTEC MA 4 is designed to perform advanced photolithography alignment by using an advanced projection alignment system. The device uses a precisely calibrated illumination system and digital laser interferometry for rapid and accurate spot-on positioning of masks and substrates. KARL SUSS MA-4 is widely used for the fabrication of through-hole and flip-chip components and for the production of advanced photomasks. It has a maximum projection area of 240mm x 200mm and can handle substrates up to 4" x 6". The working magnification range is from 0.75X to 50X. Its digital camera allows for user-defined mapping at any magnification and a 9" color monitor allows for easy viewing of the mask and wafer. MICROTEC MA-4 is suitable for a variety of mask-making applications, including contact, proximity and soft contact alignments. It features a low drift scanning system for accurate pattern recognition even with high levels of noise present. Its precision stage provides a low backlash and repeatable motion and features automatic centering and corner correction capabilities. KARL SUSS MA 4's alignment performance is further enhanced through the use of its built-in repeatability compensator. This advanced feature scans each sample at two levels, compares the results and adjusts for misalignment during the alignment process. The device is also capable of storing up to nine imaging programs for easy access. MA 4 is a versatile, high performance mask aligner that has become widely used for precision photolithography applications. It has the ability to quickly and efficiently process a variety of substrates and has advanced features that allow for accurate and repeatable motion and alignment.
