What Are the Benefits of Coaxial Line Confocal Imaging?

High Resolution and Speed
The Gocator 4000 Series delivers exceptional X-resolutions and optimal Z-performance for fine feature detection and precision 3D shape and 2D intensity measurement. This is paired with fast scan rates up to 16 kHz+ (with GoMax NX or PC acceleration) to meet inline cycle times and provide a proficient scanning and inspection solution for rapid deployment into your production line.
Shadow-Free Scanning and Outstanding Angular Range
Coaxial optical design allows the sensor to scan simple and complex surface topologies with zero shadowing effect for improved data quality and more accurate measurement results on steep-angled features (e.g., step height of PCB chips), deep grooves (e.g., wafer die fractures), and protruding components (e.g. BGA solder ball bumps). The Gocator 4000 Series’ optics also deliver outstanding angular range (Max Slope Angle up to +/- 85 degrees) for excellent performance on highly curved surfaces (e.g., chamfer of cell phone display glass).
Versatility to Handle All Materials, Parts, and Features
Accurately scan any material type or part shape including OLED and glass displays, tiny solder bumps on semiconductor BGAs, transparent glue path applications in wearable consumer electronics assemblies (e.g., smart watches), and shiny machined-metal cell phone housings.
Applications
Gocator® 4000 Series coaxial line confocal sensors are designed for use in measurement and inspection applications such as Semiconductor, Consumer Electronics, EV Battery, and more.
