Abstract: Systems and methods for assembling a mobile cellular device do not require screws or adhesives, allowing for more efficient and less wasteful rework of the device when needed. In an embodiment, one or more fixed lock elements are attached to one a screen assembly of the device (or the device housing) and a locking shaft is retained in the housing (or the screen assembly). The locking shaft includes blocking sections that block passage of the lock elements, and non-blocking sections that permit passage of at least part of each lock element. In this way, when the screen assembly is mated to the housing, each lock element aligns with and at least partially passes over one of the non-blocking sections, such that when the locking shaft is slid axially, the lock elements align with and are retained by the blocking sections.

Abstract: An improved multi-functional flexible printed circuit (FPC) assembly 142 is provided for use in an electronic communications device 100. The FPC assembly 142 can comprise a curved FPC 144 a flexible substrate 156 and components thereon and can be positioned against a portion of an interior surface 137 of the housing 106 so as to share common wall surfaces for improved volumetric space utilization. The FPC assembly 142 can have a curved contour which matches a curvature of the curved housing 106. The components can include flexible metal conductors 158, multiple antennas 160 and 162, speaker felt 150 and/or a seal or gasket 146.
