Last Friday, Apple finally brought a new MacBook Pro series of products to the conference.
Although everyone is most concerned about the touch screen Touch Bar on the keyboard, Apple has made a lot of changes in other details. The famous foreign website iFixit also successfully extended the palm of the hand to the new MacBook Pro. Even if you don't buy it, you can see how it is removed.
Unfortunately, iFixit is not the most "big" Touch Bar model, but the 13-inch new MacBook Pro entry model (i5 processor version). Let's take a look at the detailed disassembly process.
This disassembly object - i5 version of the new 13-inch MacBook Pro, specific model A1708
Give X-rays to the entire computer before disassembling
Through X-ray we can also get a preliminary understanding of the general internal layout of the new MacBook Pro. The overall feeling is a lot thinner than the previous generation. Not much nonsense, direct opening
After unscrewing the 8 screws on the back (D) side, you can open the back cover directly.
The next task is to remove the battery first, but there is a touchpad Trackpad data cable above the battery, so you must remove it first.
This wide head screw secures the connection between the battery and the motherboard
Next to the power connector, there is an interface fixed with two screws, which is the Trackpad data cable. Once you remove the screws again, you can remove the Trackpad module directly.
The new larger Trackpad is also one of the highlights of the new MacBook Pro, with a holistic design and a TapTIc engine that provides force feedback. This special electromagnet responds to user actions, mimicking key feedback under normal clicks.
The next step is the new battery section, which changes the battery of the new MacBook Pro to three, compared to the previous generation that was divided into six. A total of 54.5 Whr of battery capacity is achieved by connecting between lines. In the previous generation, this number was 74.9 Whr.
After removing the battery, we were finally able to start disassembling the original on the motherboard, first the solid state drive. Apple introduced SSDs as early as the first generation of ReTIna MacBook Pro in 2012, but their interfaces and specifications have changed twice, and this time it has become the third time.
SSD master that can be seen after removing the cache
The interface aspect seems to follow the special interface of the 2014 and 2015 MacBook Pro, but the number of gold fingers is supplemented. The overall size of the SSD is greatly reduced: 2 flash memories per side; the cache is even directly on the main control chip.
According to Apple's previously announced news, the SSD uses PCI-E channels for transmission, which is similar to Intel's other NVMe for the consumer market. With the PCI-E channel directly connected to the CPU, the SSD has a significant increase in transmission rate and latency.
At the press conference, Apple also highlighted its transmission rate. After testing the 13-inch MacBook Pro, the foreign media 9to5Mac also verified Apple's original publicity. QuickBench 4.0 has a large file access speed of up to 2700 MB/s.
However, after the test file was further increased to more than 60MB, the write speed dropped significantly. This phenomenon may have something to do with the use of the cache.
Then the vocal unit was removed. As another highlight, the sounding units distributed on the left and right sides of the fuselage occupy a considerable volume, which makes it the best sound quality in the history of the MacBook Pro. .
At this point, we can finally take out the entire motherboard and feel the integration is very high in size.
Loosen the heat sink base on the back and remove the heat sink. Because there is no graphics card, the cooling module only covers the CPU, and the heat pipe in the cooling module is responsible for transferring heat from the CPU surface to the heat sink fins next to the air outlet.
Front and back of the 13-inch new MacBook Pro motherboard
First we need to take a closer look at the CPU. This time Apple adopted the Intel Core i5-6360U/i7-6660U on the 13-inch MBP. Both TDP powers are 15W. And this 6360U is actually made up of 3 small core "glue". In addition to the usual processing core and set display, the third "small core" role geometry is still unclear.
Memory that has been criticized by many people is soldered directly to the CPU with two sides on each side. Need to be reminded again that consumers can't add memory later.
Following the interface setting of the most people, it is hard to imagine that the two Thunderbolt 3 (USB type-c) interfaces and their companion chips occupy only a small space on the motherboard. This may be a key reason why Apple eventually "killed the killer."
For the cooling fan, the new MacBook Pro also uses Apple's exclusive "variable pitch fan blade" design, which is said to avoid the resonance of the original fan and reduce noise.
Next to the screen driver board, it is a small module that has both an air outlet and an antenna.
Before you disassemble the screen, take another X-ray and you can see that the internal structure of the screen is much simpler.
The rotating shaft is directly mounted on the screen module, and each side is connected and fixed by three screws.

The keyboard didn't change much, it was still a classic scissor structure, but the height of the keycap seemed to increase a bit.
In the end, we got a "family portrait" of the disassembled parts.
At the end of the disassembly, iFixit gave its own "serviceability rating" by convention. The new MacBook continued the "non-universal" nature of Apple, and at the same time used a lot of glue tape in some locations, and finally only got 2 points under the 10-point system.
to sum up
From the specific situation of this disassembly, the new MacBook Pro has once again reached a new level in the integration of its own components. After reducing power consumption through newer hardware, Apple boldly cut battery capacity directly and divided the extra space directly into the speakers.
These moves are indeed very bold. But for consumers, these changes are not easy to accept.
