Product Structure and Interface Introduction:

Memory module slot:

SO DDR4 slot: strictly built according to the SO DDR4 specification, the internal dimensions of the slot are precise, the layout of the gold finger contact area is reasonable, and the gold plating process with strong oxidation resistance is used to ensure good conductivity even after long-term use, providing reliable guarantee for the insertion and electrical connection of DDR4 memory modules, adapting to the working frequency, voltage and other parameters of mainstream DDR4 notebook memory modules, and meeting their performance testing needs.

SODDR5 slot: Designed according to the SODDR5 standard, based on the inheritance of high-precision manufacturing processes, optimized and upgraded for the new features of DDR5 memory modules, such as higher transmission rates, lower power consumption requirements, etc. The internal circuit layout is adjusted to match its electrical specifications, ensuring stable operation of DDR5 memory modules after insertion, accurately leveraging its high-performance advantages, and providing strong support for the detection of new generation notebook memory modules.

Power supply interface and switch:

3.6V button battery holder: The design is compact and reasonable, making it easy to install and remove button batteries. High quality metal spring plates are used to ensure stable battery connection, effectively preventing power interruption or poor contact caused by battery looseness, and providing a stable power source for the tester in mobile and portable scenarios.

TYPE-C interface: Following the universal TYPE-C standard, the internal pin layout of the interface is precise, and the shell is made of metal material and grounded, with good shielding performance, effectively blocking external electromagnetic interference, ensuring power supply stability and data transmission integrity. It is compatible with various TYPE-C power cables, making it convenient for users to connect external power sources.

Power selection switch: High quality toggle switch is selected, with clear operation feel and clear gear switching. Through internal circuit connection, the switching between two power supply modes is precisely controlled to ensure that only the selected power supply mode is connected to the circuit, avoiding power conflicts and ensuring the safe and stable operation of the tester.

LED bead array: composed of multiple high brightness, low-power LED beads arranged in an orderly manner, corresponding one-to-one with the memory module pins, connected through internal precision circuits, and converting the electrical status of the memory module pins into visual signals in real time. The lamp beads are packaged with long-life and high stability materials to ensure reliable illumination during long-term and frequent testing, providing users with continuous and accurate detection indicators.

Independent testing switch: Designed with a micro switch, it has fast response characteristics and can trigger the testing instrument to start the detection program at the moment of pressing. The switch is equipped with an insulated outer shell to prevent accidental short circuits, and the internal contacts are gold-plated to ensure conductivity and reliability after multiple presses, ensuring a smooth start of the testing process.

Performance advantages:

Accurate fault location: With the LED light bead indication corresponding to the memory module pin position, the fault pin position of the memory module can be quickly located with extremely high accuracy. Whether it is contact problems caused by physical damage or hidden faults such as internal circuit short circuits and open circuits, the intuitive light bead status can be exposed in the first time, providing clear direction for subsequent maintenance and component replacement, greatly shortening the fault diagnosis time and improving maintenance efficiency.

Wide power supply adaptability: The dual guarantee of 3.6V button battery and TYPE-C interface power supply ensures that it is not limited to usage scenarios. Whether in outdoor maintenance sites without external power supply or indoor laboratories with sufficient power supply, users can flexibly choose the power supply method according to the actual situation, ensuring that the tester is available at any time and enhancing the practicality and adaptability of the product in different environments.

Efficient and convenient operation: From inserting the memory module, selecting the power supply, to starting the test, the entire operation process is simple and clear. The independent test switch and intuitive LED light feedback allow users to quickly complete the inspection without complex professional knowledge and cumbersome settings, reducing the threshold for use. It is especially suitable for novice computer maintenance and scenarios that require frequent inspection of memory modules, such as daily order acceptance inspection in computer repair shops, greatly improving work efficiency.

Usage:

Choose power supply method: Depending on the usage scenario, if you are outdoors or in an area without an external power source, use a 3.6V button battery for power supply. Install the button battery correctly into the battery holder and pay attention to the positive and negative pole directions during installation; If indoors and there is a TYPE-C power supply available, use the TYPE-C power cord to connect the TYPE-C interface of the tester to an external power source, such as a computer USB interface, phone charger, etc., and then turn the power selection switch to the corresponding TYPE-C power supply position.

Insert memory module: Gently open the slot buckle of the corresponding memory module type (SO DDR4 or SODDR5) on the tester, align the gold finger of the laptop memory module to be tested with the slot, slowly and steadily insert until the memory module is fully inserted and the buckle automatically locks, ensuring that the memory module is tightly connected to the slot to avoid poor contact affecting the test results.
Start test: After inserting the memory module and preparing the power supply, press the independent test switch, and the tester will immediately start the detection process. At this time, focus on the LED bead array and observe the light emission of the beads. Under normal circumstances, all LED chips corresponding to the normal pins of the memory module should light up. If a certain LED chip is found not to be lit, it can be preliminarily judged that there is a problem with the corresponding pin.

Result judgment and subsequent processing: According to the LED indicator, if all the pins corresponding to the memory module are lit up normally, it indicates that the basic function of the memory module is normal; If any LED chips do not light up, record the corresponding pin number of the LED chips. You can refer to relevant information or consult professionals to further determine the cause of the fault, such as oxidation of the gold fingers of the memory module, poor contact in the slot, or damage to the internal circuit of the memory module. Corresponding repair measures should be taken for different reasons, such as cleaning the gold fingers, replacing the slot or memory module, etc.

Applicable scenarios:

Daily operation and maintenance of computer repair shops: In computer repair shops, when faced with a large number of laptops sent for repair, maintenance personnel need to quickly determine whether the memory module is faulty.
