If they asked for UL compliance, your logo would be implicit in that
request...Ian

Subject: [TN] Vendor Markings

I'm interested in opinions regarding Vendor Markings.  If a fabrication
drawing is silent regarding vendor markings, is it acceptable to apply
the
fabricators UL logo?  We have a customer that is angry we applied our
logo.
However, we feel we need to apply our logo for our own traceability and
ability to do failure analysis should the boards ever be in question.  

We have had several occasions where our customers return boards we
didn't
build.  It obviously is easy when we can show them the logo is not ours,
but
it gets difficult when there are no logos on the board.

They'd like us to rebuild 5 lots of boards due to not asking them if it
was
acceptable to apply our vendor id.  

Should the fabricator be responsible for requesting approval for vendor
markings on every job, or should the board buyer be responsible for
stating
no vendor markings allowed?

Your input is appreciated.
