LTE Standard Module Series EC25 Mini PCIe Hardware Design ⚫ ⚫ vias as many as possible for better heat dissipation. Add a heatsink on the top of the module and the heatsink should be designed with as many fins as possible to increase heat dissipation area. Meanwhile, a thermal pad with high thermal conductivity should be used between the heatsink and module. Add a thermal pad with appropriate thickness at the bottom of the module to conduct the heat to PCB.
