Myself, I get the impression that a "Tech" posesses some skills when it comes to using a scanner, and has a good idea about electric circuits. A mechanic, being related to the word mechanical, gives me the impression that there are few (if any) electrical devices in involved, and that the whole process leans more towards physical diagnosis and disassembly/assembly (with all of it's intricacies).

However, I usually don't think about it, and frequently interchange the two terms.
