1. Actual requirements:
1.Package: SOP/SOIC package
2. Number of Pins: 4Pin*2
3. Number of grounding connections: 0pin
4. Chip type: EEPROM, Nor flash IC high-speed testing and programming
5. Test requirements: high UPH high-speed automatic equipment test card holder, low chip impedance, high life, fast testing, supports spacing of 1.27mm, supports multiple widths and lengths;
2. Requirements analysis: According to the above requirements, the more difficult part of the design of this chip lies in the appearance design, design ok, matching adjustment, etc.; in terms of electrical properties, there are no special requirements, and only normal pins are required. Just match the corresponding ones;
3. Production: After testing the appearance dimensions and other functions multiple times, after matching and tolerance adjustment, mass production can be started after confirmation;
4. Shipping requirements: After the above test socket is confirmed to be ok, it can be shipped;
