Assembly - Huawei ME906E Manual

Assembly

It refers to M.2 specification.
The module will need a mechanical retention at the end of the board. The module specifies a
5.5 mm Dia. keep out zone at the end for attaching a screw.
The module Stand-off and mounting screw also serve as part of the module Electrical
Ground path. The Stand-off should be connected directly to the ground plane on the
platform. So that when the module is mounted and the mounting screw is screwed on to
hold the module in place, this will make the electrical ground connection from the module
to the platform ground plane.
The stand-off must provide a Thermal Ground Path. The design requirements for thermal are
a material with a minimum conductivity of 50 watts per meter Kelvin and surface area of 22
Sq mm.
