For HBM3 high-bandwidth storage DRAM chips with MPGA packaging and a speed of 6.4Gbps, the testing fixture needs to meet the following conditions:
- High-speed signal transmission capability: Due to the 6.4Gbps speed of MPGA-packaged DRAM chips, the testing fixture needs to support high-speed signal transmission to ensure the stability and accuracy of signals during testing.
- Good electrical characteristics: The testing fixture must have good electrical characteristics, including low insertion loss, low reflection, high impedance matching, etc., to ensure the matching and transmission quality between the test signal and the chip.
- Reliable contact performance: Chips in MPGA packaging need to have good contact with the testing fixture. The testing fixture must have reliable contact performance to ensure no disconnection or poor contact during testing.
- Stable temperature control: During high-speed testing, both the chip and the testing fixture will generate heat. The testing fixture needs to have a stable temperature control system to ensure the temperature remains within an acceptable range and does not affect the accuracy of test results.
- Reliable data acquisition and processing capability: The testing fixture needs to have reliable data acquisition and processing capabilities to collect, store, and analyze test data in real-time, providing accurate test results and reports.
