A process of surface treating an aluminum or aluminum alloy article includes the steps of: (1) forming an oxide layer on the aluminum or aluminum alloy article by anodizing; (2) sealing the oxide layer of the article; and (3) forming a protective film on the sealed oxide layer of the article. The process may further comprise a step of coloring the oxide layer of the aluminum or aluminum alloy article between the steps (1) and (2). The aluminum or aluminum alloy article is corrosion-resistant and resistant to damage by contact, by virtue of the protective film formed on the scaled oxide layer in the step (3). In addition, the protective film can also give the aluminum or aluminum alloy article a long-lasting attractive appearance by preventing a colored sealed oxide layer of the aluminum or aluminum alloy article from fading.

An EMI shield is used for shielding electronic components on a printed circuit board of a mobile phone. The shield comprises a cover and a pair of grounding strips, all being made by conductive material. The pair of grounding strips is soldered on the printed circuit board. A plurality of latches is formed on each grounding strip. The cover, which is substantially in the shape of an inverted U, comprises a shielding plate and a pair of rims depending downward from opposite sides of the shielding plate. A plurality of openings defined in the rims engages with respective latches of the grounding strips to secure the cover to the printed circuit board.
