After completing the circuit pattern and drilling, start placing the components. Depending on design needs, choose surface mount technology (SMT) or through-hole mounting technology (THT). The SMT process is suitable for small and complex components, while the THT process is suitable for larger components that require stronger connections.

After the components are placed, they need to be fixed to the substrate by soldering. Commonly used soldering methods include reflow soldering and wave soldering. Reflow soldering is mainly used for SMT components. It uses heat to melt the solder and fix the components. Wave soldering is mainly used for THT components, and the component pins are welded to the substrate through molten solder waves.

Finally, the manufactured AI accelerator module substrate is tested. The test content includes electrical performance testing, functional testing and reliability testing to ensure that the substrate meets the design requirements and can work stably.
