Used KARL SUSS / MICROTEC MJB-21 #82892 for sale

KARL SUSS / MICROTEC MJB-21 is a fully automated mask aligner that is used in the production of large scale electronics including integrated circuits. It is designed to be incredibly accurate, with the ability to align individual micro components at widths of 1 micron or less. MICROTEC MJB-21 utilizes a combination of pneumatic, mechanical, and optical systems in order to allow for the precise positioning of substrates and the alignment of micro components. At the heart of KARL SUSS MJB 21 mask aligner is its proprietary micro-optical equipment. This system utilizes a combination of precision lenses, mirrors, sensors, and high-speed video cameras. This unit allows for incredibly accurate alignment of substrates, measuring as small as one micron, as well as aligning individual micro components. Additionally, the optical machine is has the ability to accurately measure the position of each substrate 7 times per second, allowing for rapid adjustment of the substrate position. The mechanical workings of MJB-21 include a pair of fine-tuned linear slides, capable of moving the substrate in both the X and Y axes. This allows for extremely precise alignment of the substrate, which can be completed with a resolution of 0.001mm. Additionally, the mechanical tool includes a stepper motor which provides the required motion to the wheels. This motor can generate up to 7N of torque, allowing for rapid, yet precise movement of the substrate. The pneumatic asset of MICROTEC MJB 21 utilizes a number of pressure pads to secure the substrate and fine-tune its position. This model allows for very precise movement of the substrate with a resolution of 0.04mm. Additionally, pneumatic pressure valves are used to control the exact moment of releasing pressure off of the substrate once it has been properly aligned. KARL SUSS / MICROTEC MJB 21 mask aligner is a powerful tool for the production of large scale electronics. Its combination of pneumatic, mechanical, and optical systems allows for incredibly accurate alignment of substrates and individual micro components. With its ability to measure down to one micron, MJB 21 provides an invaluable asset for any production line of large scale electronics.
