Used QRT (Wafer Grinding, Lapping & Polishing) for sale

QRT is a renowned manufacturer of wafer grinding, lapping, and polishing equipment, providing advanced solutions for the semiconductor and electronic industries. Their systems offer high precision and efficiency, making them essential in the production of ultra-thin wafers. The wafer grinding system offered by QRT ensures excellent flatness and thickness uniformity. Analogues from other manufacturers often lack the same level of precision and reliability. The grinding process removes excess material from the wafer, resulting in a thinner and smoother surface. This is crucial for subsequent processes in semiconductor fabrication. QRT's lapping units utilize a fine abrasive slurry to remove material and achieve high surface flatness. The lapping process helps to eliminate subsurface damage caused by previous grinding, ensuring excellent planarity and smoothness of the wafer surface. The lapping machines offered by QRT have distinct advantages over competing tools, such as improved control over material removal rate and enhanced uniformity. Polishing assets from QRT provide the final finishing touch to the wafer surface. Their models employ precision polishing pads and slurries to achieve mirror-like finishes and meet stringent requirements for surface roughness. The polishing equipment offer exceptional accuracy and repeatability, ensuring optimal performance of the semiconductor devices. Examples of QRT's wafer grinding, lapping, and polishing systems include BESTPOL P260 and BESTPOL P262. The BESTPOL P260 is a wafer grinding system known for its advanced control capabilities, leading to highly uniform removal rates. The BESTPOL P262 is a lapping system that excels in achieving precise thickness control and improved flatness. These units exemplify QRT's commitment to delivering cutting-edge solutions that meet the demanding needs of the semiconductor industry.
