Sony has always been a supplier of camera sensor blocks to various mobile phone manufacturers. The international games of the Olympics, FIFA, Wimbledon, etc., and Hollywood movies were shot by Sony's cameras (Sony Entertainment accounted for 1/3 of Hollywood movies). For ordinary people, Sony accounts for 78% of this market. It can be seen how much Sony's black technology is so powerful. Today, we have to disassemble the Sony A7RII and see if there is any black technology in its internal structure! (Source: iFixit Translation: 91 demolition)
About 42.4 million Exmor R CMOS Back-illuminated Image Sensors
BIONZ X Image Processor
5-axis optical image stabilization system
4K video recording
399 Enhanced Hybrid Phase Detection AF Points
NFC and Wi-Fi connection
On the back of the camera is a foldable 3-inch 1.23-megapixel LCD display.
The left side of the camera body is equipped with a large number of I/O jacks, an HDMI jack, 3.5mm stereo headphone and microphone input, and a USB port.
The Sony A7RII is the world's first SLR camera using a full-frame back-illuminated sensor (BIS) and silent shutter, using the E-mount system.
NP-FW50 7.2 V, 1020mAh hot-swappable battery.
Sony is very conscience, not just a battery, but two.
Remove the screws that secure the base plate.
Take out the base plate and metal tripod plate.
Use a tweezer to remove the thin ribbon cable connecting the LED screen and the camera body, and separate the LED screen from the camera body.
The LED screen is a Retina screen. The internal structure of the entire LED screen can be viewed from the X-ray perspective.
First remove the eyepiece and remove the four screws in the finder frame so that you can remove the frame. As a SLR camera, the Sony a7R II does not have an optical viewfinder. However, using an XGA (1024 x 768 pixels) OLED screen in the viewfinder provides the user with an accurate image preview.
Inside the camera body's battery compartment, remove a few hard-to-find screws.
The frame and LCD panel have been removed and the rear case can be removed.
Gently pull out the cable connecting the LED screen and remove the metal fixing bracket.
Followed by a card reader.
Remove the screws that secure the metal plate of the motherboard and remove the metal plate of the motherboard.
Use a crowbar to pry apart the component wires that connect the main board one by one.
Gently remove the motherboard.
In front of the main board you can see:
Red: Sony CXD90027GF SoC
Orange: Micron 5FA98 JWB39 EMCP
Yellow: SK Hynix H5TC4G63CFR 4 Gb DDR3L SDRAM
And on the back:
Green: Sony CXD4236-1GG, it is possible to use the latest version of the CXD4236GG image processor
Light blue: Fujitsu MB9AF004 32-bit ARM Cortex-M3 processor
Dark Blue: Murata KM5601002
Come back to the x-ray perspective of the motherboard.
Remove the screw that holds the camera handle.
Remove the camera handle toward the camera's front panel.
Positive rotator and shutter buttons and Wi-Fi antennae are attached to the camera handle.
Then remove the NFC chip that is hiding behind the motherboard.
Gently tear off the silicone pad that holds the finder screen of the finder screen, and then gently pull out the OLED screen of the viewfinder.
Take away the upper housing of the camera body.
Tear off the entire silicone thermal pad that covers the Exmor R CMOS sensor. It is worth mentioning that the new Exmor R CMOS sensor on the Sony A7R II is equipped with optical image stabilization.
The Sony A7R II Exmor R CMOS sensor, which is firmly integrated with the five-axis anti-shake system, was built using Sony's own semiconductor process.
The last is the internal frame at the front of the fuselage, which is the frame of the fixed sensor and anti-shake system.
For the family portrait of a Sony A7R II, the difficulty of dismantling given by the ifixit is 4 (out of 10 points, the higher the score, the easier it is to repair). The battery can be easily replaced without tools. The tripod mount and viewfinder can be replaced without disassembling the camera body. However, the camera's internal components are very complicated and it is difficult to repair it without the Sony A7RII maintenance manual.
