Silergy Synchronous Boost Regulator Chip QFN10-2×2-0.5 Test Sockets
2. Actual requirements:
1.Package: QFN package
2.Pin number: 22Pin
3. Number of grounding connections: 0pin
4. Chip type: Synchronous boost regulator suitable for single-core or dual-core battery power management
5. Test requirements: chip aging test and programming and debugging purposes
3. Demand analysis: The chip is a boost chip. Its actual chip function is to increase the synchronous boost current from 1.8V to 5.5V and 6A. Through pin analysis, the design of its functional test is very difficult, but the current test The tests required for the project are limited to aging testing and control program debugging, so its design is not difficult.
4. Production: The chip size is small, so only the flip-top test socket can be used. For contact with the pressure block corresponding to the chip size, due to the small size of the chip, the pad uses a smaller probe, and the size of the probe is 0.35 mm is enough, and the temperature resistance can support -45~155 degrees Celsius; there are no special requirements for other parts, and they only need to meet the aging test requirements such as HTOL and HAST.
5. Quality inspection needs to focus on the size of the chip.
