Used CANON PLA 501 FA #293652732 for sale

CANON PLA 501 FA is a mask aligner tool used in the production of microelectronic devices. This aligner is designed to accurately position photomasks or reticles over a substrate in the manufacture of semiconductor components and integrated circuit devices with a high degree of precision. The device features a highly accurate optical alignment system and a CCD camera-based imaging system. The machine is designed to ensure accuracy in the mask placement process through its automated alignment features. CANON PLA-501FA is made of two sets of steep-field lenses, which each contain two objectives, two eyepieces, two light beams, and a rotating turret. The light beams are used for alignment purposes, while the turret rotates to enable the machine to be capable of alignment with either manual or automated operations. The aligner's precision operation enables it to achieve an alignment accuracy of up to 20 microns at a rate of 500 alignment sampling points per second. PLA 501FA has a variety of functions to allow operators to customize their alignment operations. These features include a rotary arm which is used to rotate and scan the mask or reticle before placement, a die-to-die or die-to-fiducial alignment mode, backside alignment, image transfer alignment mode, and automated alignment mode selection. The aligner also provides image capture capabilities for high-resolution images of the mask for use in further analysis or for adherence to quality standards. Given its accuracy and repeatability, CANON PLA 501FA is an ideal tool for large-scale production of microelectronic devices. The device can accurately align reticles, assist in stencil creation, and improve quality control in the production process. The aligner also offers comparative alignment capabilities to allow for detection of defects between patterns by comparing optics across reticles on the same substrate. Additionally, the aligner is easily integrated into existing production lines, making it a valuable investment for any production facility.
