Many illiterates believe that quantum mechanics is just a mathematical game with no practical value. Haha, let's find a ancestor for computer chips, please take a look at the demonstration:

Before designing multi-layer PCB circuit board, the designer needs to first determine the circuit board structure according to the scale of the circuit, the size of the circuit board and the requirements of electromagnetic compatibility (EMC),

With the full-scale production of the Dongcheng factory, Shengyi Electronics' business volume in Huawei has increased year by year in recent years, and it has been Huawei's main PCB supplier.

A semiconductor is a substance with a conductivity between that of a conductor and an insulator. It is not very conductive in a pure state, but its conductivity can be adjusted by adding impurities (doping) or changing the temperature. The typical representative of semiconductors is silicon, which is widely used in the manufacturing of electronic components. Semiconductor technology is the cornerstone of modern electronic devices, such as smartphones, computers, digital cameras, etc., all rely on semiconductor chips. In addition, semiconductors are also very important in the energy field, such as semiconductor materials, which are the core of solar cells

Therefore, as the "Hundred-Day Plan" unfolds layer by layer, under the circumstance that China must guarantee foreign reserves and protect the exchange rate, the Chinese government has no choice but to raise interest rates or raise interest rates in disguise.

According to market reports, Huawei and other non-Apple flagship HDI expanded release orders, which will add momentum to the PCB factory's off-season operations in the first quarter of this year.
