Linked semiconductor equipment such as testers, coaters and steppers provide unique testing challenges that require synchronization and data validation across multiple SECS communication interfaces. With PFAT’s support for testing multiple SECS connections, PFAT test scenarios bridge the gap between disparate equipment communication interfaces. Leveraging PFAT’s dynamic testing abilities, data received from one equipment interface can be used as input to control secondary or downstream equipment and even used by the tests to perform conditional execution.
PFAT can now operate as either an active or passive entity within the SECS communication protocol. This allows creation of test suites that can verify your equipment behaves correctly when configured as the active entity for use within specific factory scenarios.
Our products continue to adopt new computing technologies, enabling our customers to take advantage of new computing platforms as they become available. PFAT has added support for the Windows® 8.1 operating system and Microsoft® SQL Server 2014 Express.
We have also resolved many customer-logged issues and requests for PFAT. Please contact us for details.

Static testing—using fixed data input values—is inefficient and has limited success in increasing equipment software reliability in production. PFAT™ provides easy-to-use mechanisms that let you vary your input values and dynamically alter test scenarios based on real-time results. With PFAT’s dynamic testing capability, you can increase your test coverage, closely simulate a production environment, and run fully automated reliability test suites.
PFAT tests can now reference data from collection event reports, equipment-initiated custom SECS messages, and equipment replies. This data can be used for test decision logic as well as can be input to other test and SECS messages. This capability further increases the dynamic nature of PFAT tests, thus increasing the reusability of test scenarios.
PFAT’s ability to integrate with equipment software as well as independent applications and simulators allows every engineer in the equipment supply chain to share a common equipment software testing platform that includes test plans and results.
In this release, full cycle equipment software testing with PFAT’s integrated SEMI E84 test capability is now supported. An interactive E84 control dialog along with sample E84 test scenarios give test designers the tools to quickly leverage this capability.
In addition to integrating with customer software that supports a .NET remoting interface, PFAT is now able to communicate via Microsoft’s Windows Communication Foundation (WCF), thus further expanding the possibilities of PFAT’s testing scope.
To continue to reduce the test design effort, we have identified areas for productivity improvements by targeting the tasks a user needs to repeat during test design. In this release we have reduced the effort to create and maintain the events and associated event reports that are used throughout test scenarios.
Our products continue to adopt new computing technologies, enabling our customers to take advantage of new computing platforms as they become available. This also includes dropping support for older technologies. PFAT no longer supports Microsoft Windows XP and Windows Server 2003 operating systems as well as development tools of Visual Studio 2005, and .NET Framework 2.0. PFAT has added support for Visual Studio 2012 and .NET Framework 4.0 and 4.5.
PEER FACTORY® Acceptance Tester (PFAT™) version 1.10 is an upgrade release that further expands the capabilities added in the 1.9 release; namely, dynamic test design and execution, the integration of customer applications into PFAT test scenarios, multi-language support, and equipment configuration integration.
Static testing—using fixed data input values—is inefficient and has limited success in increasing equipment software reliability in production. PFAT provides easy-to-use mechanisms that let you vary your input values and dynamically alter test scenarios based on real-time results. With PFAT’s dynamic testing capability, you can increase your test coverage, closely simulate a production environment, and run fully automated reliability test suites.
In 1.10, PFAT tests are integrated with a random number generator giving you more options for simulating equipment operation in production. You can leverage this capability in the design of your timing tests, to alter real-time test execution paths, and to vary data supplied to your SECS messages. With this ability you can test a higher percentage of abnormal scenarios to verify that equipment recovers correctly.
PEER FACTORY® Acceptance Tester (PFAT™) version 1.9 is an upgrade release that expands dynamic testing capabilities, integrates customer applications into PFAT test scenarios, and reduces test setup time with expanded configuration import capabilities.
PEER FACTORY® Acceptance Tester (PFAT™) version 1.8 is an upgrade release with a focus on expanding operating system support, as well as providing new features and fixes to existing capabilities.
PFAT now integrates with custom implementations of the PEER Property Manager and External Data Processor that have been developed using Microsoft® Visual Studio® 2010 and Microsoft® .NET Framework 4.0. Integrating components using Microsoft® .NET Framework 1.1 is no longer supported.
We’ve expanded PFAT’s use within automated equipment software build and testing environments. PFAT’s command line test execution now provides additional information to manage errors as well as the capability to override global properties to simplify changing global data in an automated environment.
As an enhancement to the test management support already provided by PFAT through test import/export, PFAT now includes a test file transfer utility to automate the process of moving test-related files. This utility is useful when changing your default working directory.
We have also resolved several customer logged issues and requests for PFAT. Please contact us for details.
PEER FACTORY® Acceptance Tester (PFAT™) version 1.7 is a minor release with new features and enhancements to existing capabilities.
This version of PFAT contains the following new features and enhancements.
PFAT has extended its event handling capabilities to allow custom processing on the report data attached to event notifications that are received asynchronously from the equipment. With the external data process test activity, you can connect a PFAT test to an external data processing component, which can perform any action using the report data as input.
PFAT provides a .NET interface that allows you to develop your own data processing component to meet your specific requirements. You can create a custom data processing component that is used to perform advanced validation of the report data where you need to compare the reported data to data stored elsewhere. Custom data processing components can also provide results back to the PFAT test, allowing pass/fail determinations to be made by the custom component.
With this capability, you can now integrate your advanced data validation SQA processes within your PFAT test scenarios.
PFAT's production-level testing capabilities have been further enhanced with the introduction of varying delays in test scenarios. This capability allows actions within a test to be performed at varying intervals, providing behaviour that more closely resembles that which is encountered during production. With the ability to introduce varying wait times throughout the lifetime of a test scenario, you can also test a higher percentage of abnormal scenarios to verify that equipment recovers correctly.
In addition to our existing seat licensing model, PFAT now supports a flexible enterprise model that works with your team member's individual needs. A PFAT license can be acquired at run-time for temporary use or can be assigned for longer-term use, such as during a testing cycle or for off-site testing.
PEER FACTORY® Acceptance Tester (PFAT™) version 1.6 is a minor release with new features and enhancements to existing capabilities.
The PEER Property Manager application was added to provide the following functionality:
PEER Property Manager provides a mechanism for communicating with other software applications during the execution of PFAT test scenarios. These components communicate with each other using a user-defined set of properties that your applications can set or react to. For example, within a PFAT system test, you can set a value on a property that can then trigger your application to perform a specific action. Within the PFAT system test, property values that are set by your application can also be read, allowing decisions within the test to be made based on the value. Processing modules, measurement components, and hardware simulators are just a few examples of applications that can be integrated with PEER Property Manager.
This enables your PFAT system tests to interact not only with the equipment through the SECS/GEM interface, but also with other software applications, allowing you to further expand your test coverage, validating advanced production-level test scenarios.
Information was added to the Execution Summary report, including more statistics and contextual information about the tests that are included in the schedule.
To support a growing list of activities in the Test Activity Toolbox, the activities have now been grouped into functional areas. You can organize these groups by alphabetical or functional order and add them to your favorites list.
The Test Activity Toolbox library has been expanded to provide enhanced support for the following capabilities:

Production-level testing capabilities
Command line test schedule execution
Enhanced equipment configuration
New reporting capabilities
Simplified test collaboration
Test activity improvements
This version of PEER FACTORY Acceptance Tester includes many new features and improvements.
Increased control when building system tests and test schedules allows for enhanced burn-in test support.
With these capabilities, you can now repeat tests for mid to long-term stability testing, execute tests in parallel for multiple load ports or error monitoring, as well as other options that let you exercise your equipment at production levels.
PFAT now supports test schedule execution from a command line interface, giving you the ability to run tests as part of automatic equipment software builds or to automate test execution for a series of tests using batch files.
Equipment configuration has been enhanced through two key initiatives: reduced effort to create equipment configurations and the ability to use context data to describe tools.
Many test activity properties use the equipment configuration as their data source. To provide more flexibility in defining tests and using them against different equipment configurations, PFAT now provides advanced validation within system tests and test schedules. Now, during design time as well as prior to execution, validation is performed to ensure your tests are setup correctly before connecting to your equipment. If you change which tool you will be testing against or modify the current equipment configuration, referenced event reports, system tests and test schedules are automatically updated to reflect your changes. If an incompatibility is detected, PFAT displays which test activities need to be updated to work with the new equipment configuration.
This advanced validation provides another step in reducing your overall testing effort.
Several new reporting features are now available in PFAT.
PFAT's new test packaging feature simplifies test collaboration and test management by gathering all associated test files and including them automatically in a single zip file that is ready for transfer. This allows you to share system tests and test schedules easily within your QA team and with your customers or suppliers.
The test activity toolkit library has been expanded to provide enhanced support for the following capabilities:
