Product Structure and Interface Introduction

Memory module slot:

SO-DDR3 is stamped and formed using ultra precision molds, creating nearly perfect dimensional accuracy for the 204 pin slot and extremely high compatibility with the memory module's gold fingers. The metal pins inside the slot are finely polished and surface gold-plated, which not only have excellent conductivity, but also have excellent oxidation resistance, effectively preventing poor contact problems after long-term use. The edge is cleverly designed with guiding rounded corners to facilitate the smooth insertion of the memory module. At the same time, it is equipped with high-performance elastic buckles, which quickly and automatically lock the memory module once it is in place, ensuring its stable fixation and laying a solid foundation for the stable operation of the memory module.

Four layer PCB board:

From the top to the bottom, each layer has clear division of labor and close collaboration. The circuit of the signal layer is like a fine neural network, made of low loss and high stability copper foil material, carefully carved through photolithography technology to ensure efficient and smooth signal transmission; The voltage regulator chip and capacitor in the power layer are like precision "pacemakers", continuously delivering stable power to the memory module; The large-area copper foil shielding layer of the stratum is like a copper wall and an iron wall, effectively blocking external EMI interference; The auxiliary layer in the middle optimizes the signal path and enhances the strength of the board through reasonable wiring planning and via layout. The four layers are connected through precise via connections to achieve seamless interaction between signals and power.

External interface:

The external interface of the adapter card is simple but not simple, and the connection with the testing equipment or motherboard adopts standardized design, making it easy to plug and unplug. The interface shell is made of high-strength engineering plastic, which has excellent insulation performance and mechanical strength, effectively resisting damage to the interface caused by static interference and external collision. The plug-in design is tightly fitted and can automatically lock after insertion to prevent loosening, providing a solid guarantee for subsequent testing work.

Performance advantages

Cost reducer: With excellent gold finger protection mechanism, it significantly reduces the wear and tear of DDR3 memory modules during testing, greatly reducing the number of scrapped due to wear and tear, and directly reducing raw material costs. At the same time, precise adaptation features and efficient testing process optimization have shortened testing time, improved production efficiency, indirectly reduced labor and equipment usage costs, and brought considerable cost-effectiveness to enterprises.

Signal Quality Guardian Model: The four layer PCB design ensures high-quality signal transmission from the root. The low loss signal layer, stable power layer, and powerful shielding layer work together to ensure that DDR3 signals can remain pure and stable in complex testing environments, providing strong support for engineers to obtain accurate testing data, avoid misjudgments caused by signal interference, and improve product quality control capabilities.

Testing efficiency improvement engine: Accurate 204Pin adaptation and convenient external interface design make the insertion and removal of memory modules easy and fast, reducing testing preparation time. The wide range of application adaptability enables engineers to test various memory modules without the need to frequently replace adapter cards, further improving testing efficiency and accelerating product development and production processes.

Usage method

Installation of adapter card:

Align the SO-DDR3 memory module test protection card with the corresponding interface on the testing device or motherboard, slowly and smoothly insert it, ensuring that the interface is fully inserted into place. A crisp "click" sound indicates a secure connection. At this point, gently pull the adapter card to check for any signs of looseness.

Memory module installation:

Pick up the DDR3 memory module that needs to be tested, align its golden finger with the 204Pin slot of the adapter card, pay attention to the correct insertion direction, and slowly insert it with moderate force until the memory module is fully inserted into the slot. At this point, the elastic buckle inside the slot will automatically fasten the memory module, ensuring its secure fixation. If the buckle is not fully fastened, gently press the buckle to make it tightly fit the memory module.

Pre startup inspection:

After the installation of the memory module is completed, carefully check whether the connection between the adapter card and the memory module is tight, whether the buckle is fixed to the memory module, and whether there are any looseness, misalignment, or other situations. Meanwhile, observe whether there are any foreign objects obstructing the testing equipment or motherboard. If everything is normal, prepare to start the testing equipment.

Usage and monitoring:

After starting the testing equipment, pay attention to whether the system starts normally and whether there are any error messages. During the testing process, the working status of the memory module, such as temperature and read/write speed, can be monitored through the built-in monitoring tools or third-party software of the testing equipment. If the memory module is found to be unstable, overheated, or frequently reporting errors, it should be stopped immediately to check whether the connection between the memory module and the adapter card is loose, whether the gold fingers are oxidized, whether there are electromagnetic interference sources around the testing equipment, and to identify and solve potential faults to ensure smooth testing.
