Wunstorf, Germany 2001-04-20. The X-ray inspection of multilayer PCBs increasingly requires an objective evaluation of e.g. inner layer misregistrations and annular ring widths at through-hole platings. After the recent release of the new software ?ml|module? by phoenix|x-ray the necessary measurements of test patterns and vias can be performed easily and exactly. As all the application orientated software modules by phoenix|x-ray the ml|module can be integrated into auto-positioning (CNC) inspection programmes. The ml|module completes the microfocus X-ray system ml|inspector which was specially developed for the inspection of bareboards. The ml|inspector can be equipped with an 80 kV or a 130 kV X-ray tube and achieves a detail detectability of down to 3 microns which makes it also the ideal tool for the inspection of microvias. The auto-positioning system (CNC) enables to test a high quantity of boards in the manufacturing process. The system can be perfectly applied in shift-production and is highly recommended due to its ease of use.
