Huawei P40 Pro disassembled in detail: screen more than BOE, still has U.S. components

On the evening of March 23, Huawei held a global online launch to officially announce this year’s new flagship P40 series, including the Huawei P40, Huawei P40 Pro and Huawei P40 Pro Plus models. Although the P40 and P40 Pro will not be officially released and sold until April 8, many media have been given the first time to evaluate the machine.

On March 31, the domestic technology media “XYZone” also took the lead in releasing the Huawei P40 Pro’s disassembling video on ACFUN and the microblog smh.com.au, and according to XYZone’ dismantling found that the core components of the P40 Pro came mainly from mainland China (mainly Huawei Heath’s self-research chip), Taiwan, South Korea and Japan. However, among RF front-end devices, Skyworks, Qorvo, Qualcomm and other U.S. companies still have products.

The Financial Times then published a commentary saying that “although Huawei is on the list of entities in the United States, Huawei’s P40 series of handsets still contain US parts”.

So next, let’s take a closer look at XYZone’s dismantling of Huawei’s P40 Pro:

First remove the SIM card, because the Huawei P40 Pro is supporting IP68 waterproof and dustproof, so we can see that the inside of the SIM tot is a waterproof and dust-proof rubber ring.

After removing the SIM cardholder, remove the screws on the bottom. Then heat the hot air gun to 90 degrees, after 3 minutes, with a suction cup to absorb the back cover, with the tearmachine piece along the back gap slowly cut open, you can open the back cover.

It should be pointed out that because the machine supports IP68 level waterproof and dustproof, so the internal use of a lot of glue, resulting in the process of removing the back cover has taken a lot of effort. There is also a thermal graphite sheet on the right side of the bottom of the back cover, which corresponds to the position of the speakers inside the phone. There is also a large piece of buffer foam in the middle of the rear lid.

In the upper right corner of the rear cover, that is, the position of the corresponding camera, also has a protective component for the rear module. After all, the p40 Pro’s rear-camera module costs are high, and the focus on protection is inevitable. Earlier, Yu Chengdong has revealed that the P40’s rear-film module costs more than $100, it is clear that the P40 Pro’s rear module costs are higher.

Looking at the internal layout of the fuselage, compared to the previous generation of Huawei P30 Pro, we can see that the internal layout of the Huawei P40 Pro is similar to it, but the rear camera module takes up more space, the motherboard and the battery and sub-plate space below are further compressed.

Eleven fixed screws need to be removed before the motherboard and camera module can be removed.

First to dismantle the front module. The front camera and the infrared sensor have a layer of thermal graphite on the back and are secured by a screw. After removing the screws, the front and infrared can be removed.

Then take out the potential optical lens module, you can see that the potential optical module is relatively large in size, and separately equipped with a roll-down frame.

Next, take out the other three rear cameras. The three cameras can be seen being fixed together.

Huawei P40 Pro disassembled in detail: screen more than BOE, still has U.S. components

Specific parameters, the main camera is the use of Sony’s IMX700 sensor, RYYB photosensitive pixel arrangement, 50 megapixels, the sensor area is 1/1.28 inch of the large base, which is currently the largest mobile phone lens sensor, can be increased by 40% of the amount of light, equivalent focal length of 27mm, support OIS optical stabilization.

However, Huawei did not point out that in normal mode, the 50-megapixel main image output s12.5 megapixel stake.

There’s also a 40-megapixel (four-in-one to 10-megapixel) ultra-wide-angle lens, a Sony IMX608 sensor, f/1.8 aperture, with an equivalent focal length of 18mm.

The Huawei P40 Pro features a 12-megapixel periphoto optical zoom lens, using a Sony IMX351 sensor, for an equivalent optical zoom of 5x, effectively between 4.6x and 4.7x.

It should be noted that previous industry chain news shows that the image sensors of Huawei’s P40 series of telephoto lenses were supplied by Howie Technologies, which was acquired by Weir, but from the dismantling point of view, at least the P40 Pro telephoto CIS was used by Sony.

Of course, this can not be ruled out, Howie Technology is also a supplier of the P40 series telephoto CIS.

In addition, the front-facing ToF camera and rear camera are using the Sony IMX316 sensor, the front 32 megapixel camera also uses the Sony IMX616 sensor, f/2.2 aperture, equivalent focal length of 26mm.

Obviously, from the P40 Pro that XYZone dismantled, Sony is undoubtedly the biggest winner in Huawei’s P-Series image upgrade battle.

In addition, after the motherboard is removed, we can see that the flash light and color temperature sensor on the back are connected to the motherboard. It should be noted here that since the rear main camera sensor uses a RYYB photosensitive pixel matrix, this also makes it possible to have a color-biased problem when taking a picture, such as the orange shoot may turn red.

To do this, Huawei has an eight-channel color temperature sensor for the P40 Pro, which could theoretically make the colors captured more accurately.

However, according to the latestmedia photo review of the P40 Pro, the P40 Pro still has the problem of photo color.

Below, for example, the Huawei P40 Pro compares the shooting effect of the Samsung S20 Ultra (also with 5x optical zoom, shooting at night sceneunders under streetlights in normal mode), and you can see that the P40 Pro shoots are heavily color-biased and the orange turns completely red.

However, Huawei’s P40 Pro has not yet been officially launched, so Huawei is likely to address this serious color bias problem in the near future by upgrading its algorithm.

Look at the motherboard again. The Huawei P40 Pro’s motherboard is the same as the previous generation’s P30 Pro, which features a three-tier PCB stacking design. This allows for a large extent to take advantage of the internal space.

In terms of the selection of internal components, the P40 Pro series is actually somewhat similar to the previous P30 Pro.

As shown in the figure below, on the P40 Pro motherboard, the red is SKhynix H9HKNNFBMAU LPDDR4X memory, stacked over Huawei Kirin 990 5G SoC via the POP process. The green is Samsung KLUEG8UHDB-C2D1 UFS 3.0 Flash. The purple is the HiSilicon Hi1105 WiFi 6 chip.

On another small board of Huawei’s P40 Pro, we also saw the RF front-end chips that also existed on the P30 Pro, as well as The RF transceiver chips from Heath, although the models might vary.

After the motherboard is finished, let’s look at the other undismantled parts. Like the previous Huawei P30 Pro, the P40 series eliminated the traditional front handset and switched to screen sound technology. This small circular module in the image below is the key to the sound of the screen, not through the vibrating membrane to produce sound waves, but through the vibration of rigid surface (glass screen) sound. The drive part of the module consists of a coil with a magnet in the middle, while the other part is connected to the screen.

Look below the subplate and the speaker, there are 7 screws fixed, in addition to the fingerprint identification of the FPC and speaker cable, etc. , in order to remove the secondary plate.

Once the side plate is removed, the USB Type-C connector below can be removed, and the Type-C connector can be seen to be protected by a waterproof and dust-resistant rubber ring, connected to the motherboard above via a long FPC cable.

In the lower right corner below the secondary plate is the vibration motor of the P40 Pro, the same size as the previous P30 Pro, or the Z-axis linear motor, which is still a little worse than the X-axis linear motor of other friends. Instead of placing it in the upper left corner, the location moved to the common lower right corner, where the experience should be a little better than the P30 Pro.

After removing the battery, we can see that the P40 Pro is made of a 4200mAh battery, made by Huizhou Desai battery.

(Note the last line, the manufacturer is Huizhou Desai)

After removing the battery, you can see the ultra-thin underscreen fingerprint module supplied by Goodix Technology below, but to remove it, you need to remove the screen first.

Huawei P40 Pro is a four-surface flexible OLED screen, plus IP68 waterproof and dustproof design, removal needs to be very careful, after heating need scrubber, glue solution, and then with the tearing edge of the tearing and drip ingress, you can separate the screen.

After removing the screen, you can see that the corresponding phone frame below the screen has a buffer foam, and below the buffer foam there is a VC heat plate, the black part of the top right is the thermal film.

In contrast, the area of the thermal membrane and VC thermal plate at the bottom of the P40 Pro motherboard and the battery is much smaller than that of the P30 Pro, and it seems that Huawei has more confidence in the thermal control of the P40 Pro. It should be noted that the P30 Pro uses the Kirin 990 external 5G baseband, while the P40 Pro is the Kirin 990 5G with integrated 5G baseband, so the mainboard takes up less area and consumes less power and heat.

Then we look at the ultra-thin under-screen fingerprint module below, you can see that it no longer needs to be combined with ultra-short focus lens, thickness is only 0.69mm, which also makes more space inside the phone.

Next we look at the P40 Pro screen. We mentioned in the Supply Chain Analysis article of the P40 series that Huawei’s P40 and P40 Pro’s flexible OLED screens, BOE, are the main suppliers.

“The P40, P40 Pro uses boE flexible screens,” BOE Vice President Harada also said on its microblog, but did not say it was an exclusive offering.

Huawei had previously leaked the P40 series of screen vendors in its Nova6 source code, which was made public online. According to the code, the P40’s screen provider is BOE, while the P40 Pro is supplied by BOE and LG.

However, according to the P40 Pro’s mobile error report, the P40 Pro’s screen providers are LG, BOE and Samsung.

So which screen does the P40 Pro that XYZone disassembled use? We can see from the tag on the screen line that the screen is vendord for LG Display.

Looking under a microscope, the LG Display’s AMOLED screen used by Huawei’s P40 Pro is also lined with Diamonds like Samsung’s.

It is worth noting that the recent Weibo user , Meteor Yu , said on Weibo that it had taken six P40 Pros and three P40s to a Huawei store and found that three P40s and two P40 Pros were BOEAMOLED screens with “weekly winter rain arrangement” and showed a little worse than the LG AMOLED screens in diamond arrangement. Of course, LG screens are still slightly green.

However, it should be noted that the BOEAMOLED screen used in the Black Shark 3 Pro was previously a diamond arrangement. So it is not clear whether the BOEMolED screen of “diamond arrangement” also exists in the P40 and P40 Pro.

Finally, another family photo.

Summary:

Due to the existence of the U.S. “physical inventory”, we have seen in the previous dismantling of the Mate 30 Pro, the number of components in the United States has decreased significantly, although Qualcomm’s RF front-end module and the U.S. Ling Yunlu audio amplifier, but there is no Qorvo and Skyworks front-end modules, Instead, there are more Heise’s RF front-end devices and Murata’s front-end modules.

As a result, the Huawei P40 Pro was previously expected to be more of a HEIASE-researched and non-U.S. RF front-end module, and may even use other domestic manufacturers’ RF devices, but surprisingly, the P40 Pro is still the same as the previous P30 Pro. There are still RF front-end modules for Qorvo and Skyworks in the United States.

In this way, Huawei did stock up on a considerable number of Qorvo, Skyworks and other U.S. manufacturers’ devices. According to Huawei’s official statement, some of the key devices were stocked for two years, that is, under normal circumstances, enough for Huawei to take two years, so it is not surprising that the P40 series still exists U.S. components, and the 5G RF front end completely avoids Qorvo and Skyworks is not easy.

It should also be pointed out that at yesterday’s Huawei 2019 earnings meeting, Huawei Chairman-in-Chief Xu Zhijun, referring to the impact of the U.S. “embargo” on overseas sales of Chinese-made mobile phones, said that since May 16 last year, Huawei’s new phones have been unable to use Google’s GMS system, and the share of overseas revenue is also declining. Prior to that, Huawei’s consumer business outside China had grown at a rapid rate, declining rapidly after the 516.

In response to the crisis, Huawei stepped up its research and development efforts to “fill the hole” in restructuring its supply chain before recovering slightly in the fourth quarter of last year. Xu Said revealed that after may 16 was included in the list of entities, the proportion of overseas sales of consumer business fell, with an estimated loss of more than $10 billion.

Clearly, Huawei’s sales in overseas markets fell sharply last year, dying under the influence of the US entity list. While global shipments continued to grow, they were lower than previously expected.

The amount of U.S.-based components that Huawei has previously stocked should be prepared in line with the amount of normal growth that Huawei had previously estimated for the next two years, which means that Huawei’s current inventory of some U.S.-based components may still support its demand next year.

This also leaves more time for Huawei to completely replace U.S. devices through self-research and other non-U.S. suppliers.
