The Koh Young Zenith Alpha 3D AOI is a full 3D automated optical inspection machine. The Koh Young Zenith Alpha 3D AOI uses an 8 MPixel camera with 15μm resolution. The Koh Young Zenith Alpha 3D AOI has Z resolution of 1μm.[1][2]
What it is
General reference — not yet source-verifiedAn automated optical inspection (AOI) machine uses cameras to inspect printed circuit board assemblies for defects after the solder reflow process. AOI systems detect missing components, incorrect part placement, solder bridging, insufficient solder, and other assembly flaws. Three-dimensional AOI adds height measurement capability, allowing more accurate detection of lifted leads, tombstoning, and solder joint shape anomalies.
How it works
Illumination is provided by an IR-RGB LED dome-style light source. The inspection speed is 27.14 cm² per second in 3D mode. The integrated camera can read both 1D and 2D barcodes on the PCB or carrier. The system includes an integrated calibration check wedge for verifying measurement accuracy and can detect foreign objects on the board.[1][2][5]
Applications
General reference — not yet source-verifiedThree-dimensional AOI is used for inspecting solder joints, component presence, polarity, offset, tombstoning, and other post-reflow defects. The height measurement capability enables detection of lifted leads and insufficient solder fillet height.
