2 INSTALLATION

2.1 .net Framework

The IPC-7351 LP Suite was written using Microsoft software. The LP Suite requires your computer to have Microsoft .net Framework (dotnetfx.exe) installed in order for software to work. The 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

from this Microsoft URL:

Select the Download Link and Scroll down to this line.

After you select the Redistributable Link, select the Download Button.

Don’t forget to choose the

correct language setting used on your computer!

Put the .net Framework DOTNETFX.EXE file anywhere you want on your

computer and then install the .net Framework Program.

Now you are ready to install the IPC-7351 LP Wizard

IPC

2.2 Large and Small Fonts

Your Desktop Settings have multiple Font settings. 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 choose 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.

If you are using Large Fonts and would like to change them to Normal or small

fonts, simply Right Mouse Button directly on your computer desktop and select

“Properties”.

This will bring up your Display Properties. Select the “Settings Tab

”.

Next select the “Advanced Button” and then select the “General Tab”.

In the Display area there is a DPI setting pull down which will allow you to change your Font Setting. The picture below shows the setting at “Normal Size”.

IPC

2.3 Administration Rights

If you work for a large company that has an internal IT department, we have

experienced situations where the IT department sets up all the corporation

computers without “Administration Rights”.

This means that you will probably not be able to install the IPC-7351 LP Suite

program without assistance from your IT department because they are the

“Administrators” of your computer.

2.4 PCBL LP Suite Folders

When you install the IPC-7351 LP program, the default directory folder is:

C:\Program Files\PCB Libraries LP. You can change this path if you choose to. The only files that the LP Suite installation puts on your computer go in this folder.

2.5 PCBL LP Suite Updates

When installing a new version of the LP program you do not need to un-install a previous version. The LP Suite Installation will simply write over an existing install.

3 SETTING UP USER PREFERENCES

3.1 What is a .DAT file?

The LP Wizard comes stock with three .DAT files

1. PCBL_LPL.DAT – Least Environment Land Pattern

2. PCBL_LPN.DAT – Nominal Environment Land Pattern (Default .DAT file)

3. PCBL_LPM.DAT – Most Environment Land Pattern

A .DAT file stores all “User Preferences” including you default library name and

directory path. The .DAT file also stores your CAD Tool Preference.

If you are running several different CAD Wizard Interfaces, you will probably want to create several custom .DAT files and name them after each CAD Tool.

The IPC-7351 LP program installation does not include a .DAT file, but one is

created automatically the first time you run the program. When starting the

program for the first time, the User will be prompted by a message that states a

.DAT file does not exist and that one is being created.

After selecting the OK button and second message appears confirming that the file was created.

The new PCBL_LPN.DAT file is initially set to the PCB Libraries “Default”

settings. Then the User can modify the settings to customize their product usage. If you create an elaborate “CUSTOM”.DAT file then we highly recommend that

you back up the file to a safe place.

IPC

Each time you install a LP program update, the installation will not affect your .DAT file because the installer does not contain a .DAT file.

If the LP program is not reacting normally or the Search Engine is not sorting data correctly, chances are that you possibly corrupted your .DAT file. To fix the

problem, just delete the PCBL_LPN.DAT file and when you restart the program it will automatically create a new PCBL_LPN.DAT file.

We are going to review all the Preferences that affect the PCBL_LPN.DAT file.

You can manually edit the PCBL_LPN.DAT file using Wordpad or Notepad.

This is what the PCBL_LPN.DAT file looks like:
