2. The shielding frame according to claim 1 wherein the wrap-around corner portion is defined by at least one of the side walls, adjacent a respective partition end gap, including a corner extension that is perpendicular to the respective side wall and substantially parallel with the intermediate partition wall.
3. The shielding frame according to claim 1 wherein at least one of said pair of side walls has at least one side wall stiffening feature therein.
4. The shielding frame according to claim 3 wherein the at least one partition end gap comprises a pair thereof; and wherein the at least one stiffening feature comprises a respective stiffening feature adjacent each partition end gap.
5. The shielding frame according to claim 4 wherein each of pair of partition end gaps is less than about 1 mm.
6. The shielding frame according to claim 4 wherein each of the pair of end partition gaps is in a range of about 0.2 to 0.8 mm.
7. The shielding frame according to claim 3 wherein the at least one side wall stiffening feature has a radiused corner defined with adjacent portions of the base.
8. The shielding frame according to claim 7 wherein the radiused corner has a radius of less than about 5 mm.
9. The shielding frame according to claim 7 wherein the radiused corner has a radius in a range of about 0.2 to 1.0 mm.
10. The shielding frame according to claim 1 wherein said at least one intermediate partition wall comprises a plurality of intermediate partition walls.
11. The shielding frame according to claim 1 wherein said shielding frame is devoid of welded or soldered joints between adjacent portions thereof.
12. The shielding frame according to claim 1 wherein said shielding frame comprises an electrically conductive material.
13. An electronic device comprising:
a housing;
circuitry carried by said housing;
a shielding container associated with said circuitry and comprising a shielding frame and a lid covering said shielding frame;
said shielding frame comprising
a base and a pair of side walls and a pair of end walls extending upwardly from said base, and
at least one intermediate partition wall extending upwardly from said base to define a plurality of container compartments, said at least one partition wall also extending only partway between said pair of side walls to define at least one partition end gap therewith, and a wrap-around corner portion defined between said at least one intermediate partition wall and at least one side wall.
14. The electronic device according to claim 13 wherein the wrap-around corner portion is defined by at least one of the side walls, adjacent a respective partition end gap, including a corner extension that is perpendicular to the respective side wall and substantially parallel with the intermediate partition wall.
15. The electronic device according to claim 13 wherein at least one of said pair of side walls has at least one side wall stiffening feature therein.
16. The electronic device according to claim 15 wherein the at least one partition end gap comprises a pair thereof; and wherein the at least one stiffening feature comprises a respective stiffening feature adjacent each partition end gap.
17. The electronic device according to claim 16 wherein each of pair of partition end gaps is less than about 1 mm.
18. The electronic device according to claim 16 wherein each of the pair of end partition gaps is in a range of about 0.2 to 0.8 mm.
19. The electronic device according to claim 15 wherein the at least one side wall stiffening feature has a radiused corner defined with adjacent portions of the base.
20. The electronic device according to claim 19 wherein the radiused corner has a radius of less than about 5 mm.
21. The electronic device according to claim 19 wherein the radiused corner has a radius in a range of about 0.2 to 1.0 mm.
22. The electronic device according to claim 13 wherein said at least one intermediate partition wall comprises a plurality of intermediate partition walls.
