Try several approaches and don't hesitate to ask a librarian for help.
E.g., search "International Conference on Computer Aided Design" as the Author, then scroll to the title of interest. If known, limit by year of the conference or any other keyword.
E.g., IEEE mechatronics
NOTE: Exact title searching is not recommended due to the variability in the format of conference titles.
Most professional organizations offer access to their sponsored conferences.
