P-roductivity E-nhancement T-oolsTM ELPASO Inc. W239 N1690 Busse Rd., Waukesha, Wi. 53188-1150 voice: 414-523-1100, fax: 414-523-1104 EDALINK BBS: 414-523-1103 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. ------------------------------------------------------------------------------- Some of what is shipped in a library...
