This dismantling also comes from iFixit, who has already removed all the new products that Apple can buy this month. Apple TV 4K is roughly the same in appearance compared to the old models, but the bottom part is equipped with a more favorable heat-dissipation hole, and the tail end is abolished by the USB-C interface, and the MENT button on the remote controller adds a circular frame.
The dismantling of the Apple TV 4K is very simple. The bottom cover is removed and the oncoming one is a big fan. This cooling fan is larger than the old ones. It seems that playing 4K HDR content brings more heat to the internal hardware, and Apple also added EMI shielding protection to prevent interference with audio and video signals.
iFixit said that the structure of this fan is like a disc weapon in TRON. What do you think? What, what? More like a donut?
Below the cooling fan is the motherboard, this time Apple TV 4K's core improvement is the motherboard A10X processor, and currently on the 10.5 and 12.9-inch iPad Pro also useful, for the 6-core architecture, 10nm process process, in The frequency on Apple TV 4K will not be higher.
There is also a Broadcom BCM55762 Thunderbolt to Gigabit Ethernet + USB 3.0 chip on the motherboard, which comes with 3GB of LPDDR4 memory from SK Hynix 2GB+1GB, which is stored as Toshiba's 32GB flash memory. On the other side of the motherboard is a DP1.2 to HDMI 2.0 chip and Wi -Fi/Bluetooth chip.
In the power supply part, the specifications of Apple TV 4K are 12V, 1.083A, which is higher than the previous generation of 0.917A, but the circuit board design is basically the same as the original one. The AC-IN interface is connected to the circuit board with wires. Indirect welding for ease of maintenance.
iFixit gives Apple TV 4K a repairable score of 8 points. It is easily disassembled with plastic snaps. The modularization of parts is easy to replace and repair. The screws are all standard hexagons, but the bad part is that the main part is welded to the logic board. On the other hand, if there is a problem with the interface, it may require board-level soldering or even entire board maintenance.
