1.1 Basic Features
The IPC-7351A LP Viewer was co-developed by IPC and PCB Libraries, Inc. for
the sole purpo of accessing accurate CAD land pattern dimensional data,
derived from component dimensions, to build high quality CAD library parts for
PCB design layout.
The u of the IPC-7351A LP Viewer will help standardize CAD Land Pattern
Names which will help standardize schematic symbol land pattern “footprint”
references. The LP Viewer will also help automate the PCB Asmbly process
with Zero Component Orientations, Land Pattern Origins, Pad Sizes, Pad Spacing, Pad-stack Data, Pad Shape and Component Placement Courtyard boundaries,
Silkscreen Outlines & Polarity Markings, Asmbly Drawing Outlines & Polarity
Markings, Post Asmbly Inspection Dot Usage, Reference Designator Height and Width. The 3D Component Outline Data for mechanical drafting software that does 3D component rendering will assist mechanical engineers to accurately access the PCB data in the enclosure that it’s going to reside in.
The basis for this tutorial is to familiarize IPC-7351A LP Viewer Urs with the
basic fundamental features of the software program.
Reviewing this tutorial will quickly bring you up to speed with the u of the IPC-
7351A LP Viewer software product.
There are 5 basic features that we will cover in this tutorial:
1. Setting up “Ur Preferences”
2. How to u the “Search Library” feature
3. Basic explanation of the “SMD Calculator GUI”
4. How to u the “SMD Calculator” to Search for existing components
5. How to u the “Help” feature
Even though we will only cover one or two component families in this guide, all references in this tutorial are applicable to every component family. This tutorial should be ud as a “Quick Start” to expedite your learning curve on the u of the IPC-7351A LP Viewer.
2.1 Framework
The IPC-7351 LP Suite was written using Microsoft VB software. The LP Suite requires your computer to have Microsoft Framework () installed in order for VB software to work. The VB software program is fairly new
and the only OS that has it already installed is Windows XP Professional. If you
are not using Windows XP Professional you will have to download the free
Framework from this Microsoft URL:

Put the Framework DOTNETFX.EXE file anywhere you want on your
computer and then install the Framework Program.
Now you are ready to install the IPC-7351A LP Viewer
2.2 Large and Small Fonts
Your Desktop Settings have multiple Font ttings. Win2000 has “Large and
Small” Fonts. Windows XP has “Normal and Large Fonts”.
The LP Suite program works best with “Normal or Small Fonts”, but if you choo to Large Fonts, depending on you screen resolution, scroll bars could appear in
some of the LP Suite Dialog Boxes making it slightly more difficult to navigate.动物儿歌教案
If you are using Large Fonts and would like to change them to Normal or small
fonts, simply Right Mou Button directly on your computer desktop and lect
“Properties ”.
This will bring up your Display Properties. Select the “Settings Tab
”.
Don’t forget to choo the
correct language tting
ud on your computer!
Next lect the “Advanced Button” and then lect the “General Tab”.
In the Display area there is a DPI tting pull down which will allow you to change your Font Setting. The picture below shows the tting at “Normal Size”.

2.3 Administration Rights
If you work for a large company that has an internal IT department, we have
速冻汤圆煮多久experienced situations where the IT department ts up all the corporation
苍天无情computers without “Administration Rights”.
This means that you will probably not be able to install the IPC-7351A LP Viewer program without assistance from your IT department becau they are the
“Administrators” of your computer.
