This is from the UL procedure re: marking...

I see this more and more coming from abroad. The PWB logo is done in silk screen over the solder mask. Doesn't UL have a control over this vendor logo marking placement. Victor, -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of John Burke Sent: Friday, June 22, 2007 9:55 AM To: [log in to unmask] Subject: Re: [TN] Vendor Markings I do not believe that removing a regulatory logo of any form is acceptable and here is the reason why: UL approves various sites for the manufacture of goods (in this case circuit boards) The reason they do this is to benchmark an acceptable standard for safety and insurance purposes note the name UNDERWRITERS LABORATORIES. So if your customer gets you to ship boards in without markings and hence no traceability and is getting a second supply of similar but substandard boards from "El crappo circuits manufacturing co" and there is a problem with the subsequent electronics how are they going to work out the issue. Sending in boards without markings is like shipping a loaded gun in the above scenario. I would be asking for a liability waiver based on this request.

After all, it then becomes a special.... But yes, agree with the comments on indulging the customer in order to keep their business.
