The document introduces two SMT AOI machine models from ETA: 1) The ETA-415 is an offline multi-function SMT AOI machine that can accurately inspect components as small as 0201 and read 2D barcodes. It has fast programming, automatic quality control feedback, and a maximum PCB size of 430x330mm. 2) The ETA-600 is an online multi-function SMT AOI machine with similar inspection capabilities as the ETA-415. Additionally, it can inspect boards before and after reflow and automatically send OK/NG signals to separate repair trays. Both models precisely inspect components and soldering quality.
