The Component Data Manager is the tool in ASENT that allows The Component Data Manager is the tool in ASENT that allows you to edit and manage part libraries. New parts can be entered you to edit and manage part libraries. New parts can be entered here and existing parts can be modified for projects that the user here and existing parts can be modified for projects that the user has access to. Parts can also be bulk-loaded from Excel has access to. Parts can also be bulk-loaded from Excel spreadsheets to populate project part libraries.spreadsheets to populate project part libraries.

In the Component Data Manager a part may be defined once in In the Component Data Manager a part may be defined once in the library, but it could be referenced many, many times in the library, but it could be referenced many, many times in various predictions. The Reliability Manager is the tool in various predictions. The Reliability Manager is the tool in ASENT where a product tree structure is defined, and reliability ASENT where a product tree structure is defined, and reliability predictions are done.predictions are done.

Introduction

The Component Data Manager manages the static data for parts. The Component Data Manager manages the static data for parts. The static data is the information about the part that does not The static data is the information about the part that does not change regardless of how the part is used. For example, this change regardless of how the part is used. For example, this would include the quality level, rated temperature, rated power, would include the quality level, rated temperature, rated power, rated voltage, etc… Variable part data would pertain to how the rated voltage, etc… Variable part data would pertain to how the part is used. Here, we would have some of the stress data like part is used. Here, we would have some of the stress data like the applied power, applied voltage. Project defaults can be the applied power, applied voltage. Project defaults can be defined in the Component Data Manager, but otherwise, the defined in the Component Data Manager, but otherwise, the variable part data is entered in the Reliability Manager as part of variable part data is entered in the Reliability Manager as part of the prediction.the prediction.

A part cannot be added to the product tree structure or referenced in the Reliability Manager, until it is first added to a project part library. Normally this is done in the Component Data Manager, but parts can be added on the fly in the Reliability Manager or created using the Import Product_Tree.xls template.

A Prediction Can Reference Parts From Any LibraryA Prediction Can Reference Parts From Any Library

When performing a reliability prediction (in the Reliability When performing a reliability prediction (in the Reliability Manager) you can reference parts from any project part library, Manager) you can reference parts from any project part library, even if you are not assigned to that project. However, a good even if you are not assigned to that project. However, a good practice is to establish a common part library for your company. practice is to establish a common part library for your company. Over time, as this gets built up, it can be a big time saver as Over time, as this gets built up, it can be a big time saver as members of your team perform reliability predictions. members of your team perform reliability predictions.

Adding a New Part to Your Library

To add a new part to a project To add a new part to a project library, expand the project folder library, expand the project folder and find the part type that you and find the part type that you are interested in. Expand the part are interested in. Expand the part type folder to the lowest level type folder to the lowest level (i.e. For some part types like (i.e. For some part types like resistors and capacitors this will resistors and capacitors this will be down to the style level). be down to the style level).

When adding new parts, ASENT checks . When adding new parts, ASENT checks the active project library for defaults and if none the active project library for defaults and if none exist then it checks the COMMON project exist then it checks the COMMON project library. The COMMON project library is library. The COMMON project library is somewhat special, and it will always contain somewhat special, and it will always contain default values.default values.

Packages Used by Parts

Many parts use the same Many parts use the same packaging, so in ASENT when packaging, so in ASENT when you create a part you select the you create a part you select the package that it uses. Most of the package that it uses. Most of the package data is primarily used package data is primarily used when performing a Thermal when performing a Thermal Analysis. However, some of the Analysis. However, some of the package information is used by package information is used by failure rate prediction models. failure rate prediction models. For example with MIL-HDBK-For example with MIL-HDBK-217 the number of leads, seal 217 the number of leads, seal type and whether or not it is type and whether or not it is hermetic are important. For most hermetic are important. For most part types the package part types the package information does not factor into information does not factor into the failure rate calculation.the failure rate calculation.

Variable Defaults Used For Predictions

One of the most important pieces of data One of the most important pieces of data found in the Component Data Manager found in the Component Data Manager are are Variable DefaultsVariable Defaults. These are the . These are the defaults that the Failure Rate Prediction defaults that the Failure Rate Prediction uses when variable data (i.e. Applied uses when variable data (i.e. Applied voltage, applied power, etc...) is not voltage, applied power, etc...) is not supplied by the user. supplied by the user.

When variable data is missing, ASENT When variable data is missing, ASENT first checks for defaults on your active first checks for defaults on your active project, and if none exist, then it will use project, and if none exist, then it will use the variable defaults defined in the the variable defaults defined in the COMMON project library. COMMON project library.

The example above shows the variable defaults that are The example above shows the variable defaults that are defined for Fixed Tantalum capacitors on the defined for Fixed Tantalum capacitors on the DEMOCD_PRJ project library. The value for Applied DEMOCD_PRJ project library. The value for Applied Voltage is set to 10% of what the part’s rated voltage Voltage is set to 10% of what the part’s rated voltage is, and the Series Resistance is set to 1.is, and the Series Resistance is set to 1.

These are Excel spreadsheets that the user can fill spreadsheets that the user can fill in and then import to a project in and then import to a project library in ASENT. Values that are library in ASENT. Values that are left blank in the spreadsheet will left blank in the spreadsheet will be set to the Static Data Defaults be set to the Static Data Defaults defined in ASENT.defined in ASENT.
