Tearing down the Wii 2 -- Main Board Covered with Serious Shields
It was not that we acquired the Wii to play. Now let's get down to business and tear it down -- the purpose of this review. Fixed with unique Y-shaped head screws, the chassis could not be opened without a special tool. We opened the cover, but could not easily reach the main board, which was strictly shielded under several plates inside.
We finally started tearing it down. Wii's main unit was closed with unique "Y-shaped" head screws.
With the upper cover removed. Front side is facing right. The whole is covered thoroughly with layers of shield plates. We had thought Wii had no fan, but a compact fan was found attached on back face.
With the shield plate covering the optical drive removed. Shot from rear side, this photo shows fan. Green substrates on each side of fan are WLAN antennas. Two substrates are embedded at 90 degrees against each other.
With the optical drive removed. Another shield plate shows up. Heat loss fins come up through the shield plate, where the main board hided.
Main board finally showed up when we removed large shield covering major area. Shield plate is tightly fixed with a lot of screws. Removed screws are in red circle on left.
