Once the optical imaging components are chosen, the design of the XYZ precision stage motion system can be decided. The sample being imaged is much smaller than the usual field of view. Therefore, one of the cameras or the object must move along two perpendicular axes to image the complete sample (XY). The distance between the camera and the magnification objective must also be precisely adjusted to resolve the image. The Z vector is used to describe this. The Z axis is usually vertical and moves perpendicular to the XY plane to go the sample into the imaging field of view. The hardware for XYZ movements can be set up in one of three ways. The complexity of the specific application determines which one is best to choose: The sample remains fixed while the objective is moved in X, Y, and Z directions. This method performs well when imaging small objects, like a microscope slide. The intricacy of this strategy grows along with the part size. More significant travels frequently call ...

Before delving further into that, let's check what completely automatic probe stations and wafer handlers are. It might be challenging to integrate wafer handlers to construct a completely automated probe station; therefore, having a fundamental understanding of the procedure is quite beneficial. And if you are seeking the best AMAT robot, feel free to contact Kensington Labs. Wafer handling automation Fully Automated Probe Station A wafer handler, also known as a robot or material handling unit, and pattern recognition software, also known as auto-alignment, are commonly included in fully automated probe stations. Wafer Handler The material handling part of the probe system is called a wafer handler (MHU). A pre-aligner, a robot with an end-effector (paddle), cassette holders (1 or 2), a robot with an end-effector enclosure, and a safety/environmental enclosure are commonly included. It is integrated with the probe. Wafer handlers can frequently work with a wide range of wafe...
