Semiconductor chip package test socket and probe

Some data show that compared with the domestic market, the demand for semiconductor chip bases and probes in 2019 is US $182million, accounting for only about 15% of the global market. This data is obviously inconsistent with China's annual consumption of about 33% of the global chips. It is understood that the data deviation here [...]

Development and application of microwave technology

Microwave usually refers to the electromagnetic wave in the frequency range of 300MHz ~ 300GHZ. Its wavelength is about 1m to 1mm. It can be further subdivided into decimeter wave, centimeter wave and millimeter wave radar plate. Its corresponding frequencies are UHF, ultra-high frequency, SHF and EHF. With the development of modern microwave technology, submillimeter [...]

Apple is really in a hurry. The 5g version of iPhone circuit board starts printing, and the market is not far away

Looking at the current mobile phone brands, anyone who can develop their own chips can develop their own baseband. Only apple develops its own chips, but baseband needs to rely on a third party. Many people don't understand that Apple has developed mobile phones for more than ten years, and even the most difficult CPU [...]
