1. Actual requirements:
1.Packaging: Stamp hole packaging
2. Number of Pins: 60pin
3. Spacing: 1.27mm
4. Chip type: IoT module
5. Testing requirements: chip functional debugging and program debugging
2. Chip characteristics: The chip size is 30.7*40*2.75mm. The module window is adjusted to avoid the upper CMOS part. The module is mainly MCU as the core, DDR3 16-bit as the memory, and eMMC as the external memory module. In addition, the CMOS is expanded The image processing module, etc. is actually a highly integrated core board.
3. Demand analysis: It is mainly used for chip performance debugging and programming adjustment of the chip test socket. The main function requirements of the chip are not high. The main chip functions are integrated into the module. The other parts are power supply and control signals, digital Signal, the test requirements are not high, so only basic connections are required;
4. Production difficulties: The performance requirements of the chip test socket are not high, but the difficulty lies in the peripheral size of the chip. Since the core board is a PCB, its processing tolerance is slightly larger, so the design limit of the chip test socket requires more experience. , the test data can be confirmed after matching based on various samples provided by the user.
