Hello All
Information that leads to the selection of a suitable part comes from many
different sources; datasheets, stock levels, production, personal
experience,
prototyping efforts, direct measurement of samples, CAD footprint/symbols.
etc.
There is a high risk in choosing parts just because a part could be easily
found and placed in a schematic. At worst many of the other factors that
should
be taken into consideration are ignored and at best it becomes a major task
to
get the best fit to needs.
The answer is to store all this part data in an easily searched central
location. Much of it will be company specific such as supplier preferences
availability and relative to the demands of the product being designed so
a typical portal such as Part Miner etc. is essential but is only part of
the story. As Fabe suggests items like part and supplier/manufacturer
approval
status and capabilities/limits could be captured.
As intelligence is gained within a company (and amongst affiliated
contractors)
on specfic part data, suppliers and manufacturers it would be a good idea to
capture it 'on the fly' at the point of creation and immediately make it
ready
for use to all people involved in the part selection process.

Thanks for posting your interesting link, Phil.
The fact that ORCad has essentially a search engine build in to source
electronic parts is good. I see this as making the job of a buyer very
efficient. I found the recent introduction of a p.w.b. quote engine a bit of
a kludge. The only way I could see this tool as being valuable, if the board
house database was approved by veteran Protel users on this list. I do not
consider myself this highly, at this point in time.
My point is, issues that quality control would not become an issue by
accepting a low bit from this supposed tool. Ebay has a philosophy of rating
sellers in this respect. A link to such a ratings page, bases on a builders
performance/speed would be good. It could also state a builders
capabilities/limits. I may be in the dark on this, but I am not aware of
many board houses that have Protel as a working tool versus PCAD. Yes, I
have generally used Gerber outputs in the meantime and some may argue,
rightfully, that one should never let a board house have design influence.
Mr. Lomax may have some valuable insight in this respect.
Finally, for those not aware of it,
http://www.partminer.com/pm_homepage/index.html
is a good reference for sourcing electronic parts in addition to providing
substitute research. I hope that all find this link useful.
