Good Morning Kenny,

Per IPC-610-C
Marking Section 8
Page 8-1
component legends including reference designators and polarity indicators ( only applies prior to assembly processing /cleaning )

J-STD-001C

As you stated 9.2.2
Last sentence.
Where component marking visibility and legibility is desired , the contract or drawing shall 4 so state.
4 TABLE 11-1  #1a
This table section is for Nonconforming Materials or Processes.

So all in all.
If the customer / drawing does not state that the component markings  is visible  or legible  after process.  And your process and material is per standard.
Your part is good to go.
 And yes you can do more damage by reworking 
Hope I helped.
Nancy T.

Good Day Technetters,

I have searched the archives and couldn't find the answer to my question.

J-Std-001, 9.2.2, says that you can not deliberately alter, obliterate or
remove component markings. It goes on to say that random part marking
loss...... does not constitute deliberate obliteration. This doesn't say if
the later condition is OK.

We have one faction here that believes components need to have markings no
matter what. They want us to re-mark or remove and replace any components
that have had their markings degraded, due to the cleaning processes after
soldering.

I contend that we are doing more damage by removing and replacing these
components than just leaving them alone. These Class 3 assemblies are tested
and have traceability to the component level.

Replace, Re-mark or Leave Them Alone, that is the question!

Any information that could help load my cannons would be appreciated.

Thanks in advance for your responses.
