Topaq Pressure Analysis System
Pressurex/Fuji Prescale films instantaneously and permanently change color in proportion to the amount of pressure applied to them. Topaq, a Windows based system, scans and interprets the exposed film and produces digitally enhanced images and statistical reports.
The system is essentially an instrument used in QC and R&D technology in electronic packaging. Capabilities include determining pressure distribution within a laminating press for multilayer printed circuit boards and revealing uneven pressure distribution across the nip of rollers on a dry film laminator. The analysis system is also useful in detecting imperfections within the nips themselves. When manufacturing hybrid circuits, the sensor film reveals inconsistencies in resistor thickness across large area substrates. Uniformity problems are clearly revealed during thermocompression in the TAB process and designing heat sinks.
Some features include histograms of pressure levels, enlargement and reduction capabilities, pseudo-color and 3-D viewing modes and extensive smoothing, filtering and thresholding. Surface contact area down to 3 mils can be analyzed. Each image and its accompanying statistics can be saved, printed and exported for analysis in other software packages.
