TEST DEVICE
A test device for a high-speed/high-frequency test. The test device includes: a conductive block which includes a probe hole; at least one signal probe which is supported in an inner wall of the probe hole without contact, includes a first end to be in contact with a testing contact point of the object to be tested, and is retractable in a lengthwise direction; and a coaxial cable which includes a core wire to be in electric contact with a second end of the signal probe. With this test device, the coaxial cable is in direct contact with the signal probe, thereby fully blocking out noise in a test circuit board.

PREDICTING MOTHERBOARD CONNECTOR FAILURES
Motherboard connector failures can be predicted. An embedded controller can be employed on the motherboard to monitor when devices are connected to and disconnected from the motherboard's connectors. The embedded controller can maintain an event log and connector information in which it counts the number of times a device is connected to/disconnected from a connector. The BIOS can leverage the event log and the connector information to notify an end user to take action to correct or prevent possible corrosion. Training records may also be employed to predict connector failure. The training records can track and maintain baseline and periodic device training attributes. When the periodic training attributes deviate from the baseline training attributes, an end user can be notified to take action to remove corrosion.
SYSTEM AND METHOD FOR DETECTING DEFECTIVE BACK-DRILLS IN PRINTED CIRCUIT BOARDS
The present invention provides a method for detecting failed back-drills in PCBs in the process of fabricating a PCB so that the failed back-drill can be screened out or repaired. The present invention accomplishes this by adding a short to ground connection for every back-drill via that will be cut when the back-drill removes the via stub. If the back-drill is bad or failed the short to ground will fail the subsequent electrical tests. The PCB can be repaired by re-drilling the hole or via. The present invention allows for detecting failed back-drills with easy detection in the manufacturing stage using standard equipment and test procedures. This process creates a simple pass-fail measurement that uses an existing common test process to catch failed back drills in the PCB fabrication facility. This allows for easy and cost-effective repair and guarantees back-drill failures do not pass into the field.
