Matters needing attention in the production of high-frequency microwave PCB boards

With the continuous development of high-frequency electronic equipment, especially in the increasing development of wireless networks and satellite communications, information products are moving towards high-speed and high-frequency, and communication products are moving towards the standardization of voice, video and data for wireless transmission with large capacity and high speed. Therefore, the new generation of products developed require high-frequency substrates, and the process technology of high-frequency PCB board production is constantly improving to meet the needs of different users. The editor has been engaged in PCB production for more than 10 years, and summarizes the matters encountered in the production process, and briefly describes the matters that should be paid attention to in the production of high-frequency microwave PCB boards.

The experimental test data tells you what is the difference between incandescent lamps, energy-saving lamps and LED lamps

At present, most of the electricity consumption of our country's residents has been converted into LED lamps, and only a small number of energy-saving lamps are used, and almost no incandescent lamps are used for lighting. But why is this, do you know? Today, I will tell you the reason and the result with data from experimental tests.

There are many hidden worries behind the domestic replacement of third-generation semiconductors, eager for success, large technology gap, and some projects are unfinished

If you want to know the forefront of silicon-based semiconductors, you need to pay attention to TSMC's 5nm/3nm fab in Taiwan. If you want to know how the current third-generation semiconductor game is progressing, you can turn your attention to the wafer factory of Wolfspeed, the global leader in SiC substrates, located in New York, USA. The substrate material, which is technically difficult and accounts for half of the device cost, is regarded as a key link in the silicon carbide industry chain. There is also a saying in the industry that "whoever has the substrate wins the world".
