Handheld electronic device including multi-compartment shielding container and associated methods

A method for making a shielding frame devoid of welded or soldered joints between adjacent portions thereof to carry a shielding lid to define a shielding container for electronic circuitry, the method comprising:

• forming a pair of side walls and a pair of end walls extending upwardly from a base;
• forming at least one intermediate partition wall extending upwardly from the base to define a plurality of container compartments, the at least one partition wall also extending only partway between the side walls to define at least one partition end gap therewith;
• forming at least one side wall stiffening feature in the pair of side walls defined by a radiused corner with adjacent portions of the base having a radius in a range of about 0.2 to 1.0 mm;
• and
• wherein the pair of side walls, pair of end walls, at least one intermediate partition wall, and at least one side wall stiffening feature are formed to be devoid of welded or soldered joints between adjacent portions thereof.
