XT V 160  high-quality PCB inspection system

Proprietary NanoTech 160 kV source with submicron spot size

A tightly controlled nanofocus X-ray spot and the latest digital imaging technology ensure that the XT V 160 produces sharp images of micron level features even in the most challenging samples. 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 high power.

True parallel tracking for best views of BGA analysis

A combination of tilt and rotate is required to give the best unobstructed view of BGA inspection. 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.

Nikon'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.

True concentric imaging

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 layer, dual layer assemblies and complex packages.

Superior image resolution and magnification reveals all defects

The transmission target design fitted to the XT V160’s X-ray source has an ultra thin output window that enables samples to be safely placed within 250 microns of the focal spot providing up to 36000x system magnification. The patented X-Tek Xi "Open Tube" X-ray source is smaller than any other design and allows X-ray images of fine detail in thick and dense samples to be seen with ease. This high energy vacuum de-mountable unit allows views at steep angles through solder joints and heatsinks without ever running out of energy.

Advanced user friendly software interface

The XT V 160 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 customisation to suit specific inspection requirements.

Low cost of ownership and maintenance with open-tube technology

Nikon'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.

With a footprint of only two square metres, XT V 160’s volume provides a generous 406x406 mm (16”x16”) scan area in a system

Advanced ergonomics for ease of use

The XT V 160 has been designed for ease-of-use without compromising performance. With a fully adjustable console arm which ensures that all system controls are at the operator’s reach whether standing or sitting, independent of the operators height.

The software interface 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.

Ready for CT applications (option)

XT V 160 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.
