Having blown the lid off the new Chromecast, we encounter three T-5 screws securing the EMI shield and motherboard to the bottom case.

We spudger up the motherboard, only to find it held in place by... bubble gum?

On closer inspection that's actually thermal paste—a lot of it.

Hopefully that means this Chromecast won't have the overheating issues that plagued the original.

Those darker areas around the edge of the board are integrated dual-band PIFA antennas. Although this technology is similar to that used in the original Chromecast, this version actually has an adaptive three-antenna array to select the best signal.
