ZIP archive of 3.10 MB containing the Fu Kang viewer, a utility associated with Foxconn boardview files. Foxconn boards often ship layout data in formats that generic viewers handle poorly, so this program is used to open them, search components and follow nets between parts. The name gives no version number, so check the archive contents and run it on a compatible Windows system. Scan unknown executables before running them and keep a known-good copy for future boardview work.
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 @boardview_software_download. Enginerys does not host this file.
