No. of lamination layers: 4
No. of components: 445
No. of terminals: 1,174
Installed components (BOM) Installed components (BOM)
Components are separated from the circuit board and analyzed to determine their type and constant elements.
It is also possible to make orders for component charts only for the purpose of cost analysis.
Circuit board membrane exclusion
Circuit board membrane exclusion
Circuit board layer removal observation
X-ray images (image above) indicate that there are 4 laminated layers and wiring is done via through holes.
Based on this information, wiring information can be extracted by excluding membranes on each layer.
Layout wiring
Layout wiring
Layout wiring
The image above shows a photo of the wiring on a particular layer. Everything down to spots can be identified clearly. Wiring data was automatically extracted from this photo as can be seen in the image below, and a pattern can be established with pictures that do not have fluctuation. This is highly reliable information as no human processing was carried out.
Circuit diagrams

Circuit diagrams
Flat circuit diagrams are created from the extracted wiring information, and along with providing a clear view of components like the power nodes and main routing, information is arranged functionally so that operations are easy to understand.

Library data for the output based on the PDF circuit diagram and EDIF are available. Separate from this, data can also be delivered in CAD format (option).

Cross probing tool Cross probing tool
A cross probing tool allows component and wiring layouts to be highlighted on the circuit diagram.
Optional analysis
Optional analysis

Optional analysis
The analyses mentioned until here show the detailed characteristics of the product. If means including transistor multiplier measurement, provision of layout data, structural analysis (cross-section, composition, etc.), thermal analysis, and noise analysis were used, provision of data attained from these measures is also possible (optional).
