Bob,
I would broaden your speech a bit more to include all facets of
manufacturing and design. Those of us that have been around the block a few
times can easily relate to the tails of 'silly' mistakes that the
inexperienced newbees make. [I am sure I made some in the beginning as
well, but the grace of age and experience has allowed me to forget them :-)
]
It is our role, as the more experienced individuals, to attempt to guide
them down more 'productive paths'.
Most of the time they welcome the input and guidance, when presented in a
constructive manner [typically, such as this forumn], as they realize they
really do not know how the 'real world' works - only what the books say.
Unfortunately, there are times when these individuals have either placed
themselves upon an elevated pedestal, or have been placed there by
'management', and have no desire to be guided in any way. Fortunately,
these are few.
The other part of the problem appears to be with Management placing these
individuals in positions for which they are really not equipped to fly solo.
Sometimes it appears as though the 'new management philosophy' grossly
oversimplifies things by believing that all engineers, or all designers,
etc. are equal in all respects. For some reason, it appears most
comfortable for many HR and Management types to simply believe that a new
graduate is just as good as a more seasoned employee of the same designation
[engineer, designer, technician, etc....]
I could go on, as others have done, in pointing out the benefits of
on-the-job-training of these new people, but that apparently does not fit
well with modern management philosophy. Even employees are disposable, so
why bother training them! We can get a new [equal] one 'off the shelf.'
I can see how this apparent oversimplification makes management tasks
easier. Apparently, gone are the days when your manager, or supervisor took
the time to really understand each person's strengths and weaknesses. Also,
gone are the days when the manager, or supervisor, actually fully understood
the tasks themselves, and was able to wisely allocate resources accordingly.
It is 'numbers' now.
So instead of lamenting over the long lost good old days, I find it is
better to grab the grocery cart and help these new people down the aisle [if
they are willing], even if it means taking on some of the duties that HR and
Management should have done/been doing.
It is unfortunate, but these are my observations.
To all a Merry Christmas and a more stable New Year
Steve C

My Turn on The Soap Box
I 100% agree with yours & Pete Houwen's comments
No offense to anyone just starting out in design, don't take this the wrong
way, but I absolutely CRINGE
when I read some of the questions posted here & mostly on the Designers
Council forum about design.
Like "What is a via?" Pretty scary stuff!!!!!!!!
I keep hoping I won't be buying any products designed by these people.
Problem is everyone needs to start someplace
(however it would help though to have at least one other Sr. level person
with you in the dept as a Mentor)
It is a good thing is we have these types of forums & the fact that they are
actually asking questions
and not blindly muddling along is somewhat comforting. But an email forum
can't replace formal training.
Proper training in both design & CAD tool should be absolutely
required!!!!!!
Once one has had extensive design experience & been thru a few CAD systems
only then should one consider self training on a new CAD system.
But formal training does shorten that learning curve substantially.
Happy Holidays
Bob

Subject: [TN] PCB Design Rant
A follow on from
QFP centre slug over signal vias
There are some interesting comments in the QFP thread which are to do
with PCB design and they have caused me to pull out my current soap box.
I would like to be a bit extreme and say there should be a tax of a few
thousand pounds or dollars imposed upon those that give away free CAD
packages. The money raised should be provided to vendors who sell real
CAD packages to subsidise PCB layout training in order to allow cost
effective and reliable pcb design, assembly design, rework and design
for test to be taught properly.
Why is it that an electronics engineer will design a circuit and then
feel that he is competent to lay out the circuit using a free CAD
package? The fact that the CAD package was free meant that management
were not involved and the consequences of a PCB being laid out by
someone with little or no knowledge of the pcb industry or even the
assembly industry were not considered.
The list of stupid things we see is very long, it results in pcbs and
assemblies being more expensive to procure, less reliable to
manufacture, difficult to make, impossible to test, slower to get into
production and just downright rubbish. The free CAD package cannot
provide intelligent data means that a reverse engineering process is
required to attempt to undo some of the stupidities we see. Words like
DRC and libraries are an unknown for many using these packages.
Also I'd rather tell a six year old that Fred, their pet turkey, is
required as a sacrifice for thanks giving day than explain to a young
circuit designer with a free CAD package that he is delving into areas
that he should stay out of and that his layout is very bad. That doesn't
mean I don't do it but Fred's demise is easier.
I could go on but mince pies are calling
Happy winter solstice
Rex
