The film base connector is said to provide a small space interconnection with high-density flexible circuits. Micro bump arrays built on thin film substrates reportedly reduce the thickness of the connection height by more than 70% to 300 µm thick for over 100 pins.

With printable flexible electronics, finer patterns than 30 µm line and space reportedly can be generated with smaller via holes than 80 µm diameters for double sides or multi-layer flexible circuits. The multiple screen printing processes enable embedded passive for all of LCR and active components with thin flexible substrates, including polyimide and polyethylene naphthalate films.

The XiDAT XD7500NT digital x-ray inspection system is said to have submicron inspection capability and sealed tube technology. Reportedly provides oblique angle viewing of up to 70° for any position 360° around any point of the 18" x 16" inspection area. Comes standard with the Dage NT x-ray tube; provides feature recognition to 950 nm. Real-time digital inspection of 1.3 MP viewed on a 20" flat panel LCD display. System magnification up to 7,400x. Is equipped with ImageWizard software.

The Datron IVS is housed in a metal chassis. Is mounted to the Z-axis of machining centers. Said to identify fiducials within a 20 mm area; feeds offset data into Windows-based software. Can automatically adjust for skew or image-to-edge variance. In instances where a fiducial or crop mark is not found, the program pauses and gives the option of aborting or retrying. Pins ensure the part is on the fixture properly. Reportedly reduces and compensates for improper setups. Features are said to include a camera with light ring, images and cross-hairs on display, live pictures, teaching of new fiducials, capturing and storing of pictures and fiducials, image calibration, adjustment of brightness, gain and contrast (manual and automatic), a 20 x 16 mm display window, operating distance approx. 100 mm, resolution 1280 x 1024 pixels and accuracy +/-0.02 mm.

The YTV M1m AOI system includes a 3 MP thin camera and Fusion lighting. Is said to have a smaller footprint and board handling system; can adapt to pre- or post-reflow inspection and various rework and data tracking scenarios. Programming is intuitive. With CAD data input, a complete recipe reportedly can be completed in less than an hour. Includes an offline programming option. Uses several image processing algorithms. Tools include real-time color, normalized gray scale correlation, pattern matching and binary "blob” analysis.
