Embodiments of connector-less modules and associated platforms employing the module. The module employs a Land Grid Array (LGA) comprising an array of LGA pins on the underside of the module PCB that are configured to engage respective pads patterned on a motherboard or system board PCB by applying a downward force to the module PCB. A novel clip assembly is provided to apply the downward force, while also aligning the module PCB (and its LGA) to the motherboard or system board PCB. A heat shield is provided that is configured to be disposed over the module PCB to facilitate enhanced thermal spreading and lowering thermal resistance both towards the heat shield and the PCBs. Example modules include a WWAN module and an NVMe SSD module. The module PCB may employ an M.2 form factor or other form factors.
