Fourth generation "Apple TV" disassembly report that caused developers' rights to be lifted from Apple and applications to disappear

Every time a new terminal is released, it is broken up into pieces and the parts and structure are disclosedIFixitHowever, it is scheduled to be released in late October 2015 "4 th generation Apple TV"I uploaded the decomposition report, I am deprived of the developer authority from Apple and the application is deleted from the App Store.

Although the 4th generation Apple TV was not released yet, it was sent from Apple's headquarters to iFixit for device review, Apple says that Apple did not permit disassembly of the terminal. But iFixit says "Decomposition is a work that is incorporated into our DNA, it is more than anything happier to break up the gadget and examine the parts," declaring it even at risk. A few days later, an e-mail arrived from Apple, "because the decomposition act is out of the intended use of the B2B program, it may hurt the performance of the product and it broke Apple's terms of use for developers" , IFixit will be subject to suspended use of Developer account. As iFixit's iOS application was hooked up to the developer account, it seems that the distribution of the application on the App Store has been stopped.


However, according to iFixit "Since all of the functions of the application are the same as those on the mobile site, there is no problem.Application that stopped delivery was made for iOS 4 and it was considerably outdated, so we will rebuild the application in the future I will focus on the development of mobile sites, "he says of future plans. Also, it is planned to continue development for Android application.

The decomposition of the 4 th generation Apple TV which became a problem can be seen from the following.

Apple TV 4th Generation Teardown - iFixit

The 4th generation Apple TV has a dual core 64 bit Apple A8 chip, and it supports 802.11a / b / g / n / ac / Wi - Fi. It has a receiver of infrared remote controller and HDMI port. The remote control has a touch like a glass, it has a microphone, accelerometer, gyroscope, infrared transmitter, Lightning connector, and it supports Bluetooth 4.0.


The apple mark is printed large on the back of the Apple TV main unit.


Compared with the previous model (right), the height is about 1.5 times higher. For the 4 th generation Apple TV, the terminal for the USB cable is newly changed to USB Type-C.


Disassembly starts by inserting a pick into the back cover skimmer. The cover and the main body are fixed with a plastic clasp, adhesive and screws are not used.


Since the cover covering the heat sink is fixed with special hexagonal star screws,Pro Tech Screwdriver SetRemove the screws using the screwdriver.


Furthermore, when removing the plastic clasp, it succeeded to peel off the cover.


The board part is made to be able to take out by lifting as it is.


The red frame part in the center is the A8 chip and the model number is APL 1011. Hynix LPDDR3 SDRAM memory (2 GB) is installed inside the chip. The orange color is 339 S00045 Wi-Fi module made by Universal Scientific Industrial, yellow is SMSC made USB-Ethernet controllerLAN 9730, Green is 338 S 00057 of Apple memory which is similar to that installed in the MacBook made in 2015, the light blue is DP 2700 A 1, the blue is Texas Instruments PA 61, and the purple is Semiconductor DF 25 AU 010 D 030 D made by Fairchild.


At the bottom of the logic board, you can check Hynix 32GB NAND Flash H2JTEG8VD1BMR enclosed in a red frame, 1112 0206 5271 B4K made by NXP, V301 F 57K C6XF G4 of yellow frame on the orange frame.


Heat sink is arranged at the top of the main unit to let heat escape, but it seems that Apple TV itself has increased in size due to this huge heat sink. Third generation Apple TV was 3.4 V / 1.75 A, whereas for the fourth generation Apple TV it was 12 V / 0.917 A.


In addition, I can not find the cable connecting the heat sink and the logic board, iFixit analyzes "Is it supplying power with some magic, or is it passing through the screw hole fixing the logic board?" I will.


Subsequently, the attached remote control "Siri Remote" will also be disassembled. The back of the main body is a metal material like iPhone 6s, with apple marks drawn. Operation of Apple TV and normal TV operation with one Siri RemoteBoth possibleAnd that.


First of allIOpenerWarm up the front panel of the Siri Remote using melted adhesive to melt the adhesive.


The swollen part of the lower part of the main body is also designed to function as a button and glue is sticking to the entire surface, so the decomposition is difficult to decompose somewhat.


I managed to insert a pick into the skimmer with the bottom and break open.


Pen-like decomposition toolSpudgerPush in and pull off the top and bottom parts.


The place where the upper and lower parts divided was like this. The contacts of the six buttons are as follows.


On the logic board mounted on the parts of the lower part, CSR Bluetooth wireless chip CSR 1010 acquired by Qualcomm in yellow frame part, STM32L 151 QD chip made by ST Microelectronics with ARM Cortex-M3 processor on red frame part, Orange The frame part is equipped with the Broadcom touch screen controller BCM 5976 C1 KUB 6 G which is also used for iPhone 5 s / 5 c / iPad Air.


The blue frame is ITG - 3600 of InvenSense gyroscope, the green frame is TMS320C55 digital signal processor made by Texas Instruments, the light blue frame is AS5C Y523 chip made by ST Microelectronics, the purple part is TI 49 C 37 GI and TI 55 CHL 61 I made by Texas Instruments.


The cable extending from the Lightning portZIFI used the structure, it was easy to remove by picking.


It is made by combining the Lightning port and the battery of 410 mAh, iFixit evaluates that "the lightning port is not fixed to the logic board is wonderful."


The decomposition difficulty of the 4 th generation Apple TV by iFixit is 8 points out of 10, and it seems to be considerably decomposed. However, it is difficult to replace the parts fixed to the logic board.
