Hi everyone,
As this is my first post thank you for all the useful information I've already found here.
Company where I work is in electronics design / manufacturing and my question is related to PCB assembly labeling best practices.
We start the design by opening a document number for the design (eg 100050 Rev10). Document numbers have revisions(Rev 10,11..) and we increase the revision after every release. Each revision gets tied to a part number (eg 200750) which represents the whole PCB assembly. Sometimes we keep the same part number if the change is interchangeable. By reading this forum I got the impression that this is in line with best practices mentioned by some users.
My question is what kind of label should we put on the assembly that is what should be on the label? In gerbers we only mark the PCB part number (not the same as PCBA part number). We don't print any other part number in silk screen as one PCB can be used in different PCB assemblies each having its own part number.
I see two option. One is the part number only. Second in BOM part number with revision. In this case the part number does not have the revision but when an interchangeable change is made then BOM is revised which is indexed in our ERP as "part number-001", "part-number-002 etc".
I'm really interested how other do this. What do you put on the label if you even use one? Another question is how you tie the document revisions to the part numbers? We don't have PLM and our ERP does not support it so we use the table in the design document.
Thank you.
