30 DESIGN007 MAGAZINE I OCTOBER 2018 Feature by Kelly Dack, CID+, CIT EPTAC CORPORATION Have you ever Googled your name? Using the internet, I found out there are not many folks named Kelly Dack in the world, though I was surprised to find out there are a few scat- tered here and there. Now, imagine my shock if I were to be denied a loan, referred to as "Ms. Dack," or passed up for a job opportu- nity because an auditor used the incorrect pro- file data from one of the other Kelly Dacks out there during my data verification process.

And we procure a lot of quality PCBs from our suppliers using Gerber data (unless we can't). Sometimes information on an entire layer or other manufacturing files are missing. Again, Gerber data is not intelligent. It is graphic information only, and if measures aren't taken by the designer to give us clues regarding how the artwork is configured, we must stop, ask questions, and seek clarification, which takes valuable time. Working for an EMS provider, I am often asked to make sense of customers' PCB design data packages that must be audited for com- pleteness and manufacturability. Quite often, EMS operations receive data to produce a PCB design and begin the auditing process, only to be called off due to customer changes. Some- times the data is incomplete, or it is missing one or more of the data files required to fab- ricate the PCB at the supplier. There are also
