Enhanced Imaging Mechanism
High Resolving Fluoroscopic images
The NXI-2000-A equips high power X-ray source and high throughput & high resolving FPD to obtain high resolving reproducible images. This brings further precise automated inspection as well as analysis purpose.
Our Conventional Modell
High Magnification Ratio
The magnification ratio can be configured from x2 up to x20 - Suport overall checking to detailed observation. The optional oblique capturing mechanism also supports the magnification ratio from x2 up to x5, enabling you to observe the solder bump connecting state in detail.
Oblique View (Option)
Advanced Auto-Inspection Feature
Solder Bump & Solder Wetting Automating Inspection
The NXI-2000-A precisely detects minimum dia. 12 µm void happened in solder bumps. Our proprietary algorithm removes the effect on detection rate derived from the void positional variation. In addition to the void detection, several defects including bridging, missing etc. can also be automatically inspected.
Furthermore, voids occured in solder fillet of leaded components and in heat sink pad of QFPs and transistor can also be included as a target of the automated inspection.
Proprietary Void Detection Algorythm
Using our proprietary void detection algorithm, the NXI-2000-A estimates the normal solder form from the captured image, and subtracts bump elements from the estimated normal solder form to detect bumps. This process removes the effect of brightness change derived from the change in the form of solder connection, and voids happened at any position can be precisely detected.

NXI-2000-A's Void Detection Method
Visual Check System (Option)
You can perform visual check against the result and images optained through the automated inspection process by comparing with the pre-registered sample image. In addition, the inspection result data can be linked to ID information for traceability improvement, which enables you to smoothly search the inspection result using optional barcode reader.
Full-Ranged Analysis Aid Tools
Various Useful Tool to Powerfully Support Analysis Operation
You can observe the target object in detail by utilizing the fluoroscopic images obtained in this system. The NXI-2000-A offers various items which are useful at research and prototyping phase, including accurate lenght measurement and quantitative measurement based on the calibration plate.
1D Profile Drawing
2D Profile Drawing
Flow Rate Measurement
Precise Thickness Measurement
The NXI-2000-A equips a calibration plate containing thickness-brightness information. By using the calibration plate, the system converts brightness information obtained from the detector to thickness information. As a result of this conversion process, the obtained image is converted to the information close to the human sense, and the system can accurately measure thickness, volume and area of solder bump. In addition, this conversion process removes the effect of aging variation happenend in the X-ray source and detector, and is effective for numerical trend analysis.
