5 Design and Production Recommendations

5.1 Reference Circuit

As reference designs are updated periodically, please obtain relevant reference design materials through official channels.

5.2 Baseboard Layout Design

It is necessary to implement appropriate ESD protection design for all peripheral interfaces;

5.2 Heat Dissipation Treatment

As multi-core high-performance processors generate significant heat when running at full load, system-level heat dissipation must be considered when using the product.

5.4 Transportation and Production

As modules are paired with different baseboard characteristics, the specific reflow oven temperature settings during production and material placement vary by product, please evaluate specifically during production;

Since modules may have experienced different times and environments from production to final product assembly, it is essential to perform dehumidification and drying treatment for the core board before component placement;

As the module is fully exposed and is an electrostatic sensitive device, ESD protection measures must be properly implemented during handling and transportation;
