13.4 Central Library
The central library allows part inspection parameters to be shared across inspection recipes of
different board assemblies and across multiple AOI/AXI machines. Each inspection recipe can
have a central library in addition to its “local” part library. A central part library serves as a
backup information repository for inspection recipes. The central library is accessed only when
the requested information is not found in the local library. For example, when a part needs to be
added during CAD import, the software first searches the local library for the part’s information.
If the part is not found, the software searches the corresponding central library. If the information
is found it is copied from the central library to the recipe’s local library. With the central library
connected, the software will only prompt the user to train a new part if the part cannot be found
in either local nor central library.
Before using the central library it is important to setup the logical template number control file.
A logical template number uniquely identifies a template in an AXI network.
To define the location of the logical template number control file, select System>
Options>System Path from the Main Menu and click on the Folder Setup button.
On an AXI network with multiple AXI machines and offline programming stations it is
important to ensure the logical template number is unique and never repeated regardless of its
origin. The Nordson YESTECH AXI uses a file named LTMaxNum.txt for the purpose of
controlling the logical template number. There can be only one LTMaxNum.txt file on any AXI
network. For example, if there are 2 AXI machines, 1 offline programming station and two
offline review stations on an AXI network that share inspection recipes, all the stations have to
share one LTMaxNum.txt file. The LTMaxNum.txt file is setup from the System Options
dialog. LTMaxNum.txt file controls templates in both local and central libraries.
To use the central library, in addition to controlling the logical template number, you must also
make sure the part rotation information is consistent across the entire environment. Failure to do
so may cause recipe corruption when the part data is merged from the central library to the recipe.

Here are the two simple steps to setup a new Central library:
1. Create a folder for the central library e.g. Central Lib#1.
2. In the YesAX software set the central library path to the folder just created by selecting
Central Library, Setup Parameters from the Part library pop-up menu.
(Central library path can also be setup from the New Recipe dialog, or using the YCD file
header)
After setting up the central library folder, the user can save and retrieve part information with the
central library. The operation that retrieves part data from the central library is called “Get” and
the operation that saves part data to the central library is called “Check In”. Part data is time
stamped whenever a modification is made to the part. Both “Get” and “Check In” operations rely
on the time stamp to ensure no inadvertent data overwrite.
13-6 Part List and Part Libraries
The central library usually contains many more part numbers than the local library. During the
CAD import process new part numbers are pulled from the central library on an as-needed basis.
Pull in additional part numbers by using the Get New PNs from Central Lib button. Pressing
the button launches a dialog that lists all the part number in the central library that are not in the
local library. Select the part number(s) and press the Add button to pull those part definitions
from the central library and copy them into the local library.
You can optionally store part package information in the central library. It is like having a central
package library. To enable the option, check the Store Package Information in Central
Library checkbox in the Central Library Setup dialog.
NOTE
With this option enabled it is even more critical that the part rotation is consistent
across all recipes. Establishing a rotation convention is highly recommended.
User can use Appendix 27.3 Part Rotation Worksheet to help establish the
convention.
You can also optionally store recipe specifics in the central library. This includes information
such as the part lists, recipe notes, local part information and map view backgrounds. To enable
this feature, check the Store Recipe Specifics in Central Library checkbox in the Central
Library Setup dialog..
To check in the “recipe specifics” of the existing recipes into the central library, press the Check
In Recipes button. A dialog opens that lists the recipes that can be checked into the current
central library. Check in one or several recipes at a time.
