Re: BOMs, BOMs, more BOMs
The complexity of the complete design work is shocking when you start your job. Carry out a real project work during your school time it somewhat mandatory. One thing I like to emphasize on Bills list is documentation - for most engineers a real burden because it is not solving a engineers problem and they dont like it.

Other classes for the EE
I firmly believe that an engieneering student needs to take classes in other engineering aspects to broaden their knowledge and give them some insight to other needs. For me, taking statics, dynamics and thermodynamics have all been helpful. My elective was just one of these, but I felt all were important.

Now one can go to MITOpenWare to pick up those other knowledge classes for free.

Re: BOMs, BOMs, more BOMs
That is a good description of how we did things at Philips - several layers of BOMs and Sequence of Events documentation. And all the steps were exquisitely detailed.

BOMs, BOMs, more BOMs
Hi Bill--your summary was nicely put together.  I was reminded that when we were designing automotive electronic assemblies, we had several layers of documnetation.  There was the e-BOM for all the electronics components, but also the m-BOM for the overall assembly which typically included an assembled board as a component, plus castings, moldings, fasteners, etc.  Typically the assembly drawings for the final assembly were generated out of the 3D-CAD model; however we also needed more detailed inspection prints for sub-assemblies like cable assemblies (cables cut/stripped to specific lengths/tolerances, then assembled to connectors, then the whole thing assembled into the final assembly).

Some interesting lessons learned that most starting engineers don't think of--mainly, if you want to control it, it has to be on the BOM and/or drawing or anything can happen.  A great example is calling out the specific kind of solder to be used; in some of our cases there was more than one kind (one for board SMT, another for soldering cables, etc.).  Leaving the choice of solder up to the manufacturing line turns out not to be a good idea!

Sometimes the "old" is more than merely "new again", but instead is the only viable solution to a challenging technical problem.
