BGA144 portable system processor test socket

1. Actual requirements:

1. Package: BGA144 package

2. Number of Pins: 144

3. Number of grounding connections: 0pin

4. Chip type: portable system processor

5. Test requirements: 30-hour test at room temperature of 30°C. This can be integrated into debugging and routine testing, followed by commercial-grade testing at -45~125°C for 100 hours, as well as performance debugging.

2. Requirements analysis: First is the aging test, which is a 30-hour test at room temperature of 30°C. This can be integrated into debugging and regular testing, and then there is a commercial-grade test at -45~125°C for 100 hours. This needs to be based on the design of the test socket. Drawings are used to design the burn-in test board; the second is performance debugging. Since this is an entry-level all-in-one portable processor, its frequency, low power consumption, and low requirements for probes can be matched with conventional test probes. ; Finally, after the program is compiled and written into the chip, the corresponding interface needs to be confirmed accordingly. Currently, this chip has open serial ports, UART interfaces, etc. On the premise that the test socket is arranged with all 144 pins, the corresponding programming adapter board should be designed according to the user. That’s it, or the interface can be integrated on the basis of the original test board, which can be connected through an external programmer and programmed and debugged.

3. Production: Based on the above requirements and rough analysis, we need to match the materials corresponding to the requirements, and then process and assemble them. A BGA144 portable system processor test socket that can meet the three needs is completed.

4. After production is completed, all dimensions of the test socket will be inspected for quality, and each dimension marked on the drawing will be strictly inspected. Once confirmed, the test socket can be assembled; finally, the chip sample will be used for the final matching test of the test socket, and it can be shipped if it passes the test.
