Nikon XT V 130C Electronics X-ray System

The microfocus source is equipped with a reflection target, offering a 3 micron spot size. XT V 130C system uses an vertical mounted, open-tube X-ray source that guarantees a low cost-of-ownership. The advanced electromagnetic lens is computer controlled to ensure that the image remains in focus at all kV settings and the target does not burn when using highest powers.

A combination of tilt and rotate is required to give the best unobstructed view of BGA balls. The next step is to scan along the rows to inspect for failures. With standard manipulators, this necessitates the simultaneous operation of 3 axes - requiring considerable skill on behalf of the operator. X-Tek’s true parallel tracking maintains the X and Y axes parallel to the BGA, allowing the rows to be scanned using a single X or Y axis. This feature is enabled as part of the advanced system control concept.

The operator chooses a region of interest (ROI) to inspect and positions it in the centre of the screen. Under any combination of rotate, tilt and magnification, the ROI remains completely locked into the center of the field of view. The true concentric imaging feature operates over the entire scan area of the manipulator. The ROI stays locked in, regardless of the sample’s position on the manipulator table, ideal for inspecting around single or multiple BGA balls.

The XT V 130C system incorporates all features to generate high quality images from electronic samples

• Leading proprietary micro-focus source technology
• 320x image magnification enables users to zoom in on any specific item of interest
• 1Mpixel 12bit camera with 6” image intensifier
• Accurate control of the power and direction of the emitted X-ray beams
• Qualitative real time X-ray imager (25 frames per second)

The measurement volume is easily accessible through a large hinged door and can easily hold larger boards or multiple components for automated inspection.

The XT V 130C incorporates the most advanced image capture and analysis software running on the latest specification processing hardware. The resulting data can be saved or exported directly any COM compliant package e.g. Word, Excel, Access and SPC systems . Processing hardware and software are both controlled in-house so that advances in technology can be passed on to the user without delay. Inspect-X includes special functions for inspection of semiconductor package voids, wire bonding and BGA solder bumps. It also makes use of Microsoft VBA as a scripting/macro language, allowing rapid software customization to suit specific inspection requirements.

X-Tek’s open X-ray tube development has driven down the size, weight and cost of the system whilst maintaining superior quality and performance. By introducing a patented zero-maintenance cable-less HT generator, the preventative maintenance has been dramatically reduced making the long term cost of ownership considerably lower than any comparable system.

And with a footprint of only two square metres, XT V 130C’s volume provides a generous 406mmx406mm (16”x16”) scan area in a system.

The XT V 130C has been designed for ease-of-use without compromising performance. Fully adjustable shelves ensure that all system controls are at the operator’s fingertips whether standing or sitting, independent of the person’s height.

The Windows control screen is laid out logically with all regularly used functions in view on single click buttons while movement of the precision joysticks gives a direct and logical response from both sample manipulator and X-ray image.

The system is highly intuitive to operate and as a result, operator training time is significantly reduced.

XT V 130C is pre-configured to turn the system into a CT system. This way 3D images can be reconstructed to gain even more insight into components and sub-assemblies.
