Air의 몇몇 사양에 대해 설명하겠습니다:
-
13.3" LED-백라이트 IPS Retina 디스플레이; 2560 x 1600 해상도 (227 ppi)
-
1.6 GHz 듀얼코어 Intel Core i5 (Turbo Boost 최대 3.6 GHz)와 Intel UHD Graphics 617 내장그래픽
-
Apple T2 커스텀 보안칩 / 보조프로세서
-
8 GB 2133 MHz LPDDR3 온보드 메모리
-
128 GB PCIe-기반 SSD
-
802.11ac Wi-Fi 그리고 Bluetooth 4.2
-
충전을 지원하는 Thunderbolt 3 (USB-C)포트 두 개, DisplayPort, Thunderbolt, 그리고 USB 3.1 Gen 2
-
-
-
내부를 탐험하기 전에, 우리는 신형 Air의 몇몇 외부 특징을 잠시 살펴봅시다.
-
아랫 부분에 작은 글자들과 색이 일치하는 별나사가 있습니다.
-
Air를 열어보니 익숙한 3세대 나비식 키보드가 우리를 맞이하고, 즉시 MacBook Pro를 떠올리게 합니다.
-
Air의 두께와 Touch ID를 제외하고는 Touch Bar-less 13" MacBook Pro와 구별할 수 없을 정도로 매우 유사합니다.
-
...그리고 "Air"라는 이름에도 불구하고 12" MacBook이 비교적 더 경량급으로 보입니다.
-
-
-
물론 약간의 엑스레이 투시 없이는 외부 관찰을 완료할 수 없습니다.
-
Creative Electron 친구들의 도움으로, 우리는 앞으로 어떤 상황이 일어날지 예측할 수 있습니다.

Just six Torx screws and a few cable connectors stand between us and logic board removal—not bad! Certainly nothing our Marlin Screwdriver Set can't handle.
-
Out it comes! The Air's logic board is not mustachioed like the Pro's, nor is it quite so minuscule as the MacBook's.
-
Next we snag the daughterboard, which hosts a (highly endangered) headphone jack and some connectors for the speaker and Touch ID sensor.
-
Also residing on this board: a Cirrus Logic CS42L83A audio codec.

Continuing the repair-friendly (or at least friendlier) trend, we find stretchy adhesive pull tabs under these elongated speakers!
-
We don't love adhesive—reusable screws are nearly always better—but hey, pulling out this iPhone-esque stretch-release stuff is loads better than gooey solvents and blind prying.
-
Plus, the mere presence of stretch-release adhesive generally means that someone at least thought about possible repair and disassembly situations.

Moving on, we direct our attention to the trackpad.
-
Unlike the newer MacBooks Pro, which have first-step replaceable trackpads, this trackpad shares a cable with the keyboard, which is pinned under the logic board.
-
As the trackpad comes out, we can't help but think of a certain TIE fighter...
-
The trackpad contains a Broadcom BCM5976C1 touch controller, a STMicroelectronics STM32F103B6 32-bit ARM Cortex-M3 microcontroller, a Macronix MX25L2006EZUI-12G 2 Mb serial flash memory, a Monolithic Power Systems MP6519 H-bridge current regulator, and a Maxim Integrated MAX11390A 10-bit analog to digital converter (likely).
-
A Texas Instruments TMP421 remote/local temperature sensor and a Bosch Sensortec BMA282 accelerometer are the only two sensors found on the frontside of the PCB.

Thanks to our friends at MacRumors, we had a hunch that removing this battery might be less nightmarish than in some Retinas we know.
-
Sure enough, we find four screws and six friendly pull-to-remove adhesive strips securing this
AirPowerAir's power pack. -
A sturdy frame, vaguely like those in Airs of old, supports the gaggle of battery cells and makes removal a snap.
-
Here it is: the 49.9 Wh power plant. In case you're keeping track, that's slightly smaller than Dell's new XPS 13 (52 Wh), but larger than Microsoft's Surface Laptop 2 (45.2 Wh) and HP's upcoming Spectre x360 (43.7 Wh).
-
Two Toshiba TPCA8087 N-channel MOSFETs are found on the battery pack PCB.

-
Things are starting to look Air-y inside this golden chassis—we can almost see the finish line!
-
Still lingering above the battery cavern are the metal antenna bracket and the new (modular!) Touch ID sensor, each secured by Torx screws.
-
FYI, the Touch ID sensor can come out directly after the smaller audio board is removed—we just chose to let it linger.
-
A few more Torx screws later, the display is free! This new Retina panel is almost the same as the one found on the MacBook Pro line, differing mainly in peak brightness (a mere 300 nits vs. the Pro's 500) and P3 color gamut support.
-
- 포트, 팬, 그리고 스피커를 포함한 많은 부품들은 모듈식이며 쉽게 접근할 수 있습니다.
- 성가신 별나사를 제외하면, 이 노트북은 다른 노트북들 만큼 쉽게 열립니다.
- 배터리는 나사와 수리 친화적인 당겨-푸는 접착제 조합으로 고정되어 있지만—접근하려면 로직 보드와 스피커를 분리해야 합니다.
- 키보드는 상단 케이스와 통합되어 있어서 수리하려면 완전히 분해해야 합니다.
- $1,200 이상 가격대의 노트북에 납땜되고 수리와 업그레이드가 불가능한 스토리지 및 RAM은 정말 실망스럽습니다.

Am I losing my eyesight, or is that fan not directly connected to any type of heat dissipating hardware? Looks like it’s either just providing a general low-pressure-air-flow throughout the internals - OR - it pushes air back through that antenna/heatsink-bracket-type-thing and coming out the other end of it?
Could you confirm or explain this in more detail?
I think it is just an exhaust fan, that removes hot air from a laptop case outside (from the right side of the case, under the screen) and creates a negative pressure inside, which helps a laptop to “suck“ some cool air from the outside through the intake on the left side of case, under the screen. The shape of the radiator ribs also suggests some airflow from left/right side of the case to the opposite side.
Serge B. -
The only thing that fan is doing is moving a (tiny) bit of air indirectly across the logic board and the heatsink. Or at least that is what I think it does. As there is no direct heat conduction from logic board to case, the fan isn’t there to cool the case, that’s for sure.
Yeah it is just a case ventilation fan, it doesn’t blow any heatsinks directly. Although with the very low TDP of the processor, a case fan with radiator type heat sink should do the job.
Tom Chai -
Yes, as the 12” Macbook with a ~5W TDP chip manages without a fan, I’m sure a slower general airflow together with that heatsink works well for the 7W chip in the 2018 MBA.
And when looking closer - the vents on either side of the antenna bracket, that the fan exhausts through on one side - air is drawn in on the other side and then guided by the vanes in the ventilation holes, allowing it to flow easily from right to left (when viewing bottom/inside of the MBA) over the heatsink cooling fins. There doesn’t appear to be any other openings in the chassi, so Apple has probably designed the airflow pretty efficiently in this fashion.
Pretty cool! Only Mac laptop I’ve seen with a fan but without heat-pipes/sinks by the fan.
