1. Actual requirements:
1.Package: eMMC
2. Number of Pins: 153
3. Spacing: 0.5mm
4. Chip type: eMMC/eMCP embedded memory chips, such as mobile phone memory chips, mobile device memory chips and set-top boxes, WIFI storage firmware, etc.;
5. Testing requirements: Chip rapid testing and mass production of firmware writing
3. Demand analysis: eMMC is currently the main memory chip for mainstream mid-to-low-end mobile devices, such as mobile phones. The chip needs to undergo Final test and corresponding firmware solution writing requirements before leaving the factory, which is what we often call quantity. According to production needs, mass production will generally test the eMMC153 chip, clear it, and write the corresponding firmware according to the test process. When the firmware is written and installed on mobile phones and other devices, it will work normally.
4. Production: Mainly based on the operating platform of the currently used automated test equipment provided by the user. According to the platform size, manipulator operating position, displacement space, etc., the corresponding test seat matching equipment is designed. As shown in the figure, it needs to match the high speed chip testing, so the structure is simple, the overall structure is light and thin, and durable at the same time; when designing and producing, attention should be paid to the support of each console hole in the structural design, and the chip gives the manipulator a sheltered position to ensure that they do not interfere with each other. The structure is divided into 2 Partially, the floating plate + base mode facilitates probe protection and high-speed buffering during rapid testing;
5. After the production is completed, strict inspection of the main dimensions will be carried out to ensure that the tolerances are within the allowable range. Then confirm that the structure of each avoidance position is ok, the adapter chip is ok, and the conduction is ok, and then it can be shipped.
