iMac (Early 2006 20-inch) Take Apart — General Information 19
EMI Shielding
The iMac enclosure is wrapped in EMI shielding that is easily torn and damaged. To maintain
a properly shielded unit, you must repair all accidental tears and cracks to the shielding by
covering them with EMI tape. Order EMI tape, part number 922-4786 (a long, thin strip) or 922-EMI tape, part number 922-4786 (a long, thin strip) or 922-
5026 (short, wide strips).
Pay particular attention to the EMI shielding inside the rear housing, shown below. The EMI shield
is easily damaged when replacing modules.
