ー米製部品3割強の苦しい事情ー

Fomalhaut Techno Solutions:

2020年8月、中国ファーウェイの5G対応基地局装置「BBU5900」を分解・分析した。

5G対応基地局装置「BBU5900」:

無線通信の制御やデジタル変調を担うベースバンドと呼ばれる中核装置である*1。

分解・分析の結果:

「BBU5900」には、ファーウェイのスマートフォンと同様、

半導体設計会社子会社・中国ハイシリコンのチップが、多数使われていた。

金額ベースで40%強が、中国製部品であることが判明した。

一方、米国製部品も30%強含まれている。

米国の制裁強化によるファーウェイのリスクも浮き彫りになった。

Huawei’s base station teardown shows dependence on US-made parts – Nikkei Asia

Huawei Technologies

still remains heavily dependent on U.S.-made chips and components for manufacturing equipment for 5G telecom base stations,

a leading revenue source for the Chinese tech giant, while being battered by the fierce fight between America and China over who controls the technologies of the future.

A breakdown by Nikkei of Huawei’s core base station unit for fifth generation wireless networks

has revealed that parts from U.S. suppliers make up nearly 30% of the product in value terms.

The dissection

has also shown that the main semiconductor device in the unit was supplied by a Taiwanese contract manufacturer.

The findings

indicate that Huawei is struggling to wean itself from dependence on overseas suppliers but currently needs to make do with stockpiled inventories.

Huawei teardown reveals US made parts were replaced by Chinese alternatives after the Ban

According to a new report, a Tokyo teardown specialist

by the name of Fomalhaut Techno Solutions opened up Huawei’s flagship Mate 30.

The teardown
was done to analyze the internals of the smartphone, which revealed various parts from different Chinese firms.

For those unaware,
the Mate 30 is a part of Huawei’s flagship series and boasts top notch specs but arrives with vanilla Android without Google services due to the ban.
