hi,

i'll take a run at this.  we don't use a reference designator for purely mechanical parts.   they are identified on drawings with a 'find no.' (ie a reference to a parts list).  reference designators are associated with schematics, among a lot of other things.  they are put on assemblies to assist electronic types in troubleshooting assemblies.  mechanical parts are not all that important to them.

a caveat for my response is that i don't consider connectors to be a mechanical part.  if you do, then go to an ansi document and look up the reference designator for them (eg j1-e).

so,  this is a long way to say that i've never seen reference designators assigned to mechanical parts.  of course that doesn't mean they aren't.

phil

To All

I have a  question about what is used as a reference designator for a
mechanical part that is added to the PCB during the assembly process and

is not a post soldering process. This part is a mechanical part that is
soldered to the PCB as a keying feature. Similar to a 7343 part. What do

you use to denote this type of part?
Any input would be appreciated.

Thanks in Advance

Paul Brionez
