What parts of domestic mobile phones are foreign, and Huawei cpu is not entirely domestic?

Although this result is hard to say, after careful analysis, most of the important parts of our domestic mobile phones come from abroad. Once the supply of foreign mobile phones is cut off, more than half of them will close down. Last year's ZTE ban sounded the alarm for us, so let's visit which domestic mobile phones are foreign parts. Huawei's overall performance is good, but it still can't get rid of foreign core technologies and products.

Answer the first question first. What parts are there from abroad in domestic mobile phones (core parts that cannot be replaced by domestic products in a short time)?

That's what we usually call a processor, but this is not just the CPU we think, but a collection of chips, which integrates CPU, GPU (graphics card), NPU(AI chip), baseband chip, ISP image processing chip and so on. At present, the only commercially available processor chips in the world are Qualcomm Snapdragon, Apple A series, Huawei Kirin series, MediaTek and Samsung Exynos series. In our country, except Huawei, all domestic mobile phones are equipped with Qualcomm Snapdragon chips (a few are equipped with MediaTek and Samsung), which cannot be replaced by domestic chip companies in a short time.

That is, we often hear about Sony IMX series, such as IMX586' s 4800W pixel photosensitive module, which is the core component of a mobile phone camera system. At present, Sony and Samsung are widely used in domestic mobile phones, and even Huawei has adopted CMOS sensor modules jointly developed with Sony. The domestic market is basically blank.

A very humble little thing, but at present, the domestic mobile phone memory is still all from abroad, and the provider is mainly Samsung. At present, there is no alternative resource in China (not to mention TW).

At present, domestic screens have made great progress, represented by JD.COM and Tianma, but the overall performance and yield still can't meet the current domestic mobile phone market. Therefore, most of the screens in the high-end field of domestic mobile phones come from foreign manufacturers such as Samsung and LG, and most of them are Samsung AMOLED screens, while the LCD screens used in low-end mobile phones have been basically made in China. At present, the scratch-proof glass cover on the screen is also from Corning Company of the United States, which is what we often call Corning Gorilla Series. There are manufacturers of domestic glass panels, but their performance can't compete with them.

Let's talk about the second question first. Is Huawei Kirin series SOC made in China?

Huawei's Hisilicon Kirin can be regarded as a domestic chip in theory. Although the architecture provided by ARM is adopted, it is also made in China in terms of power management, baseband chip and NPU chip, and it is one of the most domestic mobile phone chips at present. However, it should be noted that there is still a gap between Huawei's Kirin processor and Qualcomm/Samsung/Apple's chips, although both adopt ARM architecture and solutions. Huawei directly uses the core architecture provided by ARM for encapsulation. For example, Kirin 980, which we are familiar with, directly adopts A76 core architecture, and GPU directly applies the public version of Mali public architecture. Qualcomm Snapdragon, which we are familiar with, is a magic version of ARM's core architecture, while Apple's A series is adjusted at the bottom instruction set level, and then packaged into its own core architecture. This is also the gap between Huawei and other chip giants. However, judging from the current information, Huawei has been authorized by ARM at the instruction set level. I believe that in the near future, Huawei can also build its own core chip architecture.

Generally speaking, our domestic mobile phones still rely heavily on foreign core accessories, so it is a long way to go, and we should cherish it. I hope our domestic mobile phones are getting better and better, and we will build domestic mobile phones with complete intellectual property rights as soon as possible.

Here I take Huawei as an example, because the topic mentioned Huawei! However, because there are many models of mobile phones, I take Huawei P30 as an example, which is the latest model. In addition, there happened to be a supplier list of Huawei P30 in the previous stage. Let's see which parts are probably foreign.

Summary: There are 15 domestic suppliers mentioned above, but BOE is not included. If P30 uses BOE screen, you can add another one. Foreign suppliers are 18, mainly American companies, followed by European companies, and finally Japan and South Korea.

As for Huawei Kirin chip, it is based on ARM architecture, and the design and development are all Huawei's own, but it cannot be said that this chip is foreign. Architecture is not enough for a chip. It is not that people who buy this architecture can develop their own chips. The technical barriers in this area are still relatively high. However, Huawei has been on the road of self-developed architecture. It is reported that Kirin 990 adopts a brand-new architecture independently developed, and the AI chip is also based on the independently developed Da Vinci architecture.

Well, as can be seen from the above, in today's globalization, no one can make a mobile phone independently, and all suppliers need to provide more professional accessories. So in the field of mobile phones, the integration of suppliers is also very important. Without effective integration, no good products can be made. Finally, for the core chip, Huawei has adopted a self-developed way, which is the most correct way, as long as there are other professional parts manufacturers around.

Thank you for reading. Give me a compliment and encouragement. Welcome to the Roche entomological society. Thank you ~ ~

Except "patriotic function" is made in China, everything else is imported! ! !

Some parts of domestic mobile phones come from abroad. In fact, this is a normal performance, and it also represents economic globalization and national economies. Technology, products, etc. You have me and I have you, which is the final result of economic market regulation.

Now let's talk about what important parts of domestic mobile phones are foreign.

1. CPU

Even Huawei only uses its own Kirin chip in most high-end machines, and the patented technology in Kirin chip is jointly owned by Huawei, domestic enterprises and foreign companies.

Some of Huawei's low-end chips are Qualcomm 600 or 700 series chips. Of course, this is partly because of Huawei's own production capacity and strategic factors.

From the perspective of chip supply, the provider of chip design architecture is mainly ARM, and this big brother is the same regardless of the second brother.

CPU chip manufacturers mainly include Intel, MediaTek and Perfect Electronics.

Step 2: Camera

Speaking of cameras, the familiar manufacturers are probably Sony and Samsung. At first glance, they are all foreign, but at present, the three major domestic cameras are esoteric cinematography, lt, Yu Shun and Qiuti Technology.

Yu Shun and O 'filia are among the best, but their supply is in the low-end market, and the high-end products are Sony, LG and Samsung.

3. storage.

At present, it seems that most of this stuff belongs to Samsung. However, domestic chips are also working hard, such as Changjiang NAND.

4. RF part

Radio frequency (RF) is the abbreviation of radio frequency. Simply put, radio frequency is the part related to communication and telephone.

Huawei's RF connector suppliers mainly include the RF antenna suppliers Haoxun, Qorvo and Rosemburg.

Connector suppliers mainly include Amphenol, Guang Lai and Zhongli Electronics.

5. Screen section

Although the supply from JD.COM and Shenzhen Tianma is still strong, it only occupies a part of the market due to the relationship between quality and defective rate.

Well, it probably means that Samsung, Corning, LG and other big manufacturers still have a large number of screen suits.

In addition, there are a large number of mobile phone parts. Considering the cost and technical factors, there is nothing wrong with who has the right price and high cost performance, or who is irreplaceable.

We can see that domestic manufacturers are trying to catch up with the international level, understand the gap and catch up. In the long run, domestic mobile phones still have great potential and room for development. Catch up bit by bit!

Many domestic scientific research and innovation enterprises are also making continuous efforts, hoping that China manufacturing will get better and better!

A while ago, those who regarded boycotting foreign goods as patriotism took a good look. Patriotism doesn't have to resist foreign goods, but if you have the ability to turn these foreign goods into domestic products, then you are patriotic, and it's useless to resist. Those who resist foreign goods regard all those who buy foreign goods as traitors. To put it bluntly, you are all traitors just wandering around your house, because now these high-end equipment are all combined, and no one can live without anyone.

Including Huawei mobile phones, 70% of all domestic mobile phones are foreign ... This is no exaggeration.

The key problem is that others adopt low-grade foreign products, while domestic products depend on others. Whether you admit it or not, it is indeed others who provide opportunities for success.

Japan accounts for 88% of more than 2,000 parts of a Huawei mobile phone, while the cost only accounts for 3 1%. What does this mean? These small components, such as capacitors and inductors, are the only ones that can be considered "big", namely Sony sensors. These are substitutes, and the remaining cost chips and screens account for more than half. The topic involved here is the core technology. Huawei is self-sufficient in power management chips and self-sufficient in soc and 5g chips. The core component technologies of these mobile phones are firmly in their own hands. In recent years, the support for BOE LCD panels is basically not restricted by Samsung LG, while other domestic manufacturers can't move without Qualcomm's family!

The CPUs of Huawei, Qualcomm, Apple and MediaTek are all authorized by arm, just like a kind of building material used by everyone. However, it depends on the skill of each family, so soc performance is different. As for OEM, only Samsung can produce its own processors, and others need third-party OEM. At present, TSMC, a cpu OEM, has the strongest technical strength, so those who use ARM architecture and want TSMC to OEM Huawei are just black! !

Everything except the shell is foreign.

It can't be made in China. Accessories are only available abroad. Huawei designs CPU. Even if Intel is a CPU, it will not rely on itself. It can be done in the laboratory, and mass production cannot be done by one person.

Don't worry about domestic and non-domestic Huawei Maxim. If you buy a patent, it's your own. Huawei makes it. ...
