	A series of products for the Design Automation Professional
  GENERIC PRT LIBRARY for use with PCAD DESIGNER Series PCB Design Software

THE PROBLEM: Using PCAD effectively requires matching schematic SYMbols and PCB
Parts. While a majority of schematic symbols have a unique appearance, there
are a much smaller number of physical component footprints. A 14 pin DIP is
used for many different components. Just when you thought you had most
footprints created, along came surface mount.  At least with surface mount came
a specification, IPC SM-782 (currently A revision). Now you must create surface
mount footprints. It would sure be nice is someone created a generic PRT
library for existing schematic symbols to be packaged into.

THE SOLUTION: ELPASO Inc. ELPASO is a design automation software VAR (including
PCAD), PCAD and PCB design trainer, computer hardware dealer, engineering and
PCB design service bureau and consultant, and now a manufacturer of software
aids to the design automation community. Through our own use of PCAD in
designing boards we have come up with the PET GENERIC PRT LIBRARY for PCAD.
Generic means the PRTs do not contain any packaging information.  They are made
to have packaging data TRANSLATED into them from schematic symbols. Since we do
use and have used PCAD in a real production environment, as well as provide
support to a number of other PCAD users, we have included features into our
PRTs which we feel go a long way to help with your complete design needs. Some
of these features include:

The use of a custom layering convention which includes all PCAD default layers
with additional layers of our own design.  Some of the additional PCB database
layers are for actual size component outlines (not just a silk screen outline).
This helps to simplify the silk screen graphics (dense boards do not allow much
room for cute screen graphics) as well as provide for real graphics to be used
in an assembly drawing.  A default PCB with necessary layers paired is included
as well as a default PRT database.

The use of attributes for all component information not just drawn text. These
include VALUE/DEVICE, part number and footprint. Using attributes allows for
matching attribute information to be transferred from the schematic during the
PACKAGING phase.  Attributes also allow for a real bill of materials to be
extracted from a database, not just lists of cryptic DOS file names.  There are
also attributes for footprint (FP) so placement functions can be used (as well
as maybe some custom data extraction) and ECO=MECH for ECO to ignore
non-schematic components (mechanical components). The use of padstacks for all
component pads. This insures all routers including Shapetech can be used on the
database. All padstacks use flashes to allow for 7.0's automatic polygon
clearing functions and embedded aperture list and RS-274X photoplotting.  Over
220 padstacks are included, including optional rectangular and rounded corner
pads for SMT ICs.

Documentation! There is never enough time to effectively document internal
procedures let alone library creation. We provide documentation covering the
theory behind the library as well as a complete drawing of each component PRT
with necessary layers turned on. Not to mention a list of all PRTs including
file name, description, package types, number of pins, and library file the PRT
is contained in.

Maintenance!  Buying a collection of PRTs now is just fine, but what about 6
months from now when you start using a series of new components. Let ELPASO be
your PCB PRT librarian through the Library Subscription Service. Every library
sale includes 3 months of Subscription Service. That entitles the purchaser to
request up to 9 PRTs of their choosing, along with being able to access a
special file area of the EDALINK BBS containing all additional PRTs and related
files built by ELPASO. Obviously, this also includes full subscriber access to
the BBS (a $50/year value) covering the best in DOS, WINDOWS,ENGINEERING,
SCIENCE, HAM RADIO, and PCAD (including our own Tech Tips and utilities) and
other CAD related files. We do not leave you hanging after the 3 months. For an
additional charge, you can purchase additional per year maintenance coverage.
The additional coverage includes up to 36 customer PRT requests (along with
being able to access via BBS all new PRTs created).

Why should you buy a library from us? Let's discuss real costs. The library
currently includes about 1000 files. At $595, that comes out to about
$0.60/file. If you or your designers time is charged at a rate of $15/hour
(seems rather low), and you are budgeting $595 (the cost of the library), that
would mean you have less than 3 minutes to create a file (a PRT, a padstack,
or whatever). If your time is charged at $25/hour, that works out to about 1.5
minutes/file. Can you afford not to buy the library?

Finally, who is ELPASO? ELPASO Inc. is a well established PCAD VAR in the upper
midwest. Besides selling and supporting PCAD, we also sell and support other
electronic design automation software products as well as computer hardware. We
also do engineering/design consulting as well as PCB design services. The
company's principles have over 45 total years experience in electronic
engineering, design, management, as well as over 20 total years experience with
PCAD (from the 1.1 revision days) both selling and using.
