2. Components
2.1 Electronic probe
The core components of a probe card are electronic probes, which are small sensors that attach to a target device and receive and send electrical signals. These probes often have sharp tips that can be easily inserted into circuit boards or other devices.
2.2 Connector
Probe cards are usually equipped with connectors for connecting to test equipment or other measuring instruments. These connectors may be standard plugs, or they may be interfaces designed to work with a specific device.
2.3 Circuit board
The electronic components and connectors on a probe card are usually integrated on a small circuit board. This board may include some simple circuits to suit different testing needs.
3. Working principle
3.1 Plug in the target device
The user inserts the probe card into the corresponding slot or connector on the target device.
3.2 Connect test equipment
Connect the probe card to test equipment or other measuring instruments through the connectors on the probe card.
3.3 Data collection and analysis
Once the connection is made, the probe card begins collecting electrical signals generated by the target device. These signals can be sent to test equipment or computers for analysis and processing.
3.4 Result display
After analysis is complete, the test results are typically displayed on a monitor or other output device in graphics, data, or other form. The results can help engineers understand the device’s performance or diagnose potential problems.
