20100005123 | Tracking Manufacturing Test Changes - A process methodology and application for change control monitoring and identification used with a circuit board testing platform. This methodology uses “baselines” to track an approved collection of changes for testing a circuit board. An approver is an authorized user or a user that have permission to modify board-test parameters. Modifications of board-test parameters made by unauthorized persons are reported though a change notification system that can alert quality control systems so corrective action of the change can be taken. The change notification system associates the identity of the circuit board to the changes being made. The system uses digital signature encryption to protect the integrity and verifiability of the data from the test system and prevents data forgery. | 01-07-2010 |

20090091342 | Node Extender for In-Circuit Test Systems - A node extender adaptor to enable existing in-circuit test systems to qualify printed circuit boards with a node count larger than the number of channels available on the in-circuit tester. The node extender adaptor routes signal channels within the in-circuit test platform to a probe from multiple probes in a test fixture. The probes connect to nets on a PCB undergoing qualification tests. The node extender adaptor sits atop test resources. A custom made test fixture attached onto the node extender adaptor. The node extender adaptor comprises multiple channel router line cards. Switches on the channel router line cards facilitate the switching of channels to one of the multiple probes. | 04-09-2009 |

20090179657 | Printed circuit board for coupling probes to a tester, and apparatus and test system using same - In one embodiment, a printed circuit board (PCB) has a first side and a second side. The second side is opposite the first side. The PCB has a plurality of first contacts that provide an interface to a tester. The PCB also has a plurality of second contacts. The second contacts are provided on the second side of the PCB and provide an interface to probes of a probe layout. The PCB also has a plurality of electrical routes, with at least some of the electrical routes coupling multiple ones of the second contacts to single ones of the first contacts. | 07-16-2009 |
