Tokyo Electron
Precio Octo
The Precio Octo is a fully automatic wafer prober from Tokyo Electron. The Precio Octo handles wafer sizes from 4 to 8 inches, with specific configurations supporting 4", 5", 6", and 8" wafers. The Precio Octo can be integrated with TELPADS-O for high-speed automated probe mark inspection.[1][2][3][4]
How it works
The TELPADS-O function is an automated probe mark inspection system that uses a high-speed engine to inspect all pads and all wafers, produce quantitative quality-control data for probe marks, and reduce operator interaction by eliminating manual microscope inspection.[4]
