The screen printing of the EMMC chip is usually used to identify the relevant information of the chip, including brand, model, serial number, and so on. To see the screen print of an EMMC chip, you first need to find the small area on the front or back of the chip, which is usually a rectangular or square mark.
Then, use a magnifying glass or microscope to enlarge the screen print to the appropriate size so that it is clearly visible. In the case of magnification, you can see the text, numbers and patterns on the silk screen. When carefully observing a screen print, you need to pay attention to the fine details of each character, and you may need to use other tools or references to identify and interpret special symbols or codes in the screen print.
