Abstract

A software framework for centralizing the management of test plans, test configurations, test sources, debug information for testing electrical devices in a manufacturing testing environment is presented. A three-tier software architecture is defined that allows one-time effort and segregation of tasks related to integration of hardware devices, development of multiple applications, and testing of multiple applications.

Claims

1. An apparatus, comprising:

a test system knowledge base having a test plan and test resource database for storing test plans, and corresponding test resource configuration data, for configuring a plurality of printed circuit board assembly testers to test at least one printed circuit board assembly; and

a central test information controller configured to receive requests for the test plans from the plurality of testers and to provide the respective requested test plans, and corresponding test resource configuration data, to each of the requesting respective testers.

2. An apparatus in accordance with claim 1, wherein the central test information controller comprises a test plan and test resource controller that controls storage and retrieval of tests plans in the test plan and test resource database.

3. An apparatus in accordance with claim 1 wherein the test system knowledge base comprises a rule-based action database comprising one or more rules associated with respective components of the at least one printed circuit board assembly, the rules specifying test actions to perform on the respective components of the at least one printed circuit board assembly.

4. An apparatus in accordance with claim 3, wherein the central test information controller comprises an action knowledge database controller that controls storage and retrieval of rules and associated actions to be associated with respective components in the rule-based action database.

5. An apparatus in accordance with claim 1, wherein the test system knowledge base comprises a localization database comprising localization information for presenting test system information to a user of one of the testers, according to a specified localization parameter.

6. An apparatus in accordance with claim 5, wherein the central test information controller comprises a localization database controller that controls storage and retrieval of localization information in the localization database.

7. An apparatus in accordance with claim 1, wherein the test system knowledge base comprises a measurement data and/or statistics database comprising information related to measurement data and/or statistics collected form the testers.

8. An apparatus in accordance with claim 7, wherein the central test information controller comprises a measurement data and/or statistics controller that controls storage and retrieval of information related to measurement data and/or statistics in the measurement data and/or statistics database.

9. A test system, comprising:

a plurality of printed circuit board assembly testers;

a knowledge database having a test plan and test resource database for storing test plans, and corresponding test resource configuration data, for configuring the testers to test at least one printed circuit board assembly; and

a central test information controller configured to receive requests for the test plans from the plurality of testers and to provide the respective requested test plans, and corresponding test resource configuration data, to each of the requesting testers, the central test information controller operating as a single point of contact between the testers and the knowledge database.

10. The test system of claim 9, wherein:

the knowledge base comprises an action knowledge database for automatically generating tests for the testers; and

at least one of the plurality of testers comprises an automated test generation function that accesses the action knowledge database by way of the central test information controller for use in automatically generating tests for execution on the at least one of the plurality of testers.

11. The test system of claim 9, wherein:

the knowledge base comprises a localization database comprising localization information for presenting test system information to a user of one of the testers according to a specified localization parameter; and

the central test information controller comprises a localization database controller that controls storage and retrieval of localization information in the localization database, and controls access to the localization information by the testers.

12. The test system of claim 9, wherein:

the knowledge base comprises a measurement data and/or statistics database comprising information related to measurement data and/or statistics collected from the testers; and

the central test information controller comprises a measurement data and/or statistics controller that controls storage and retrieval of the information related to measurement data and/or statistics in the measurement data and/or statistics database.

13. The test system of claim 9, further comprising:

means for remotely accessing the central test information controller.

14. A method for centralizing test system knowledge, the method comprising the steps of:

storing test system knowledge, including test plans and corresponding test resource configuration data for configuring a plurality of printed circuit board assembly testers to test at least one printed circuit board assembly, in a centralized test system knowledge base;

receiving, at a central test information controller, requests for the test plans from a plurality of printed circuit board assembly testers; and

in response to the requests for the test plans, respectively providing to the testers, via the central test information controller, the requested test plans, and corresponding test resource configuration data.

15. A test system, comprising:

a plurality of printed circuit board assembly testers;

a knowledge base having a measurement data and/or statistics database storing information related to measurement data and/or statistics collected from the testers; and

a central test information controller comprising a measurement data and/or statistics controller that receives measurement data from the testers and controls storage and retrieval of the information related to measurement data and/or statistics in the measurement data and/or statistics database.
