ZIP archive of 4.05 MB containing TEBO View, a boardview viewer identified with the name Dehua, packaged for opening PCB layout files used in laptop and motherboard repair. The name points to software rather than a board-specific document, so no device or board number applies. Viewers of this kind let a technician search parts by designator, highlight nets, and locate test points on the layout. Scan the extracted program with antivirus software before running it and confirm which layout formats it actually supports.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @ITHINKHS. Enginerys does not host this file.
