    PCBA processing requirements to follow - patch processing plant
    PCBA is the SMT upper part on the PCB empty board, and then through the DIP plug-in manufacturing process, it will involve many fine and complicated process flow and some sensitive components. If the operation is not standardized, it will cause process defects or components. Damage, affecting product quality and increasing processing costs. Therefore, in the PCBA chip processing, it is necessary to comply with the relevant operating rules and operate in strict accordance with the requirements. The following describes the operating rules of PCBA processing

    About AT24C02 chip working principle
    The AT24C02 chip is an EEPROM device with an IIC interface. The so-called EEPROM is an electrically erasable programmable read only memory, which is a kind of ROM. It is a read-only memory, that is, power-down can continue to store data, while at the same time can be erased and rewritten under the action of ordinary voltage, which greatly facilitates the development of the single-chip microcomputer, and now many ROMs on the computer Is the EEPROM used.
