In 1936, Austrian Paul Eisler first used printed circuit board in radio. In 1943, Americans mostly applied this technology to military radios. In 1948, the United States officially recognized that this invention can be used for commercial purposes. Since the mid-1950s, printed circuit boards have been widely used.

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.

Nowadays, the automobile industry is developing towards intelligence, networking and sharing. ADAS and automatic driving technology are also advancing rapidly

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

Our common computer boards are basically epoxy resin glass cloth-based double-sided printed circuit boards, one of which is a plug-in component and the other side is a component foot welding surface. It can be seen that the solder joints are very regular. We call it the pad for the discrete soldering surface of the component feet

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.
