Finally, and now turning to FIG. 10, when the fourth strip 258 is added to the first strip 252, the second strip 254, and the third strip 256, the fourth strip creates a new symmetrical or regular pattern of airflow openings across the EMI containment component 250. More specifically, the triangular waveform formed by the interlocking segments 260 of the fourth strip 258 is offset from the triangular waveform formed by the interlocking segments 260 of the third strip 256 by approximately 180 degrees (and, thus, is also offset from the triangular waveforms of both the first strip 252 and the second strip 254 by approximately 90 degrees, albeit in the opposite direction as compared to the 90 degree offset of the third strip 256). That is, the triangular waveform of the fourth strip 258 is in antiphase with the triangular waveform of the third strip 256. Consequently, the interlocking segments 260 of the first strip 252, the second strip 254, third strip 256, and the fourth strip 258 cooperate to define the substantially rectangular airflow openings “AO6” between the strips and also form triangular seventh airflow openings AO7 above and below the strips. The seventh airflow openings define openings with an area that is approximately half of the area provided by sixth airflow openings AO6.
