The copper foil materials used for FPC flexible circuit boards are mainly divided into two types: rolled copper and electrolytic copper. It is a conductor layer bonded to the insulating material of the cover film and is etched into the required pattern through various processes. Electrolytic copper foil is deposited on a bright stainless steel [...]
The printed circuit board industry (press plate oil cooling) energy-saving unit adopts high-quality imported twin-screw compressor: the vapor compression chiller includes four main components of the vapor compression refrigeration cycle compressor, evaporator, condenser, and some metering devices. Realize different refrigerants. The emergence of ammonia refrigeration may solve this problem. Ammonia refrigeration will be the future [...]
Circuit boards are also called circuit plywood, circuit insulation boards, which contain a large number of polymer compounds including formaldehyde; after burning, they will release harmful gases and harmful smoke; they are very harmful to the human body. Pay attention to precautions and pay attention to safety at the disposal site.
Let’s talk to everyone: after China’s progress in launching 5G, even the United States is at a loss. They are all sighing, is it true that no one can stop China? So to what extent has our 5G construction reached so far? It can be said that modern society can have such advanced technology, mainly [...]
With the continuous progress of science, the main characteristics of PCB circuit boards for mobile communication terminals in the 5G era are: High density: In the design of mobile terminals, every millimeter of space saved can create huge value for end customers. By saving space, you can use larger, higher-resolution displays, larger batteries, and more [...]
The rapid popularization of 5G has not only steadily increased the construction of base stations, but the entire material industry chain related to it has also ushered in new growth opportunities. The demand for high-performance materials such as PTFE, LCP, PPS, and PPO is expected to usher in rapid growth. Among them, the LCP material, [...]
Nowadays, China's development has shown a rapid progress. With the gradual improvement of my country's economy, significant progress and breakthroughs have been made in many areas, such as trade, exploration, infrastructure, and manufacturing industries that Chinese people are proud of. They are all very famous internationally. With excellent manufacturing technology, my country has also raised [...]
The COVID-19 pandemic has imposed mandatory work model changes and a shift to remote work on large parts of the global economy, which has accelerated the pace of digital transformation already underway. Despite the uncertainty caused by the pandemic, service providers continue to use 5G. According to the latest "Ericsson Mobile Communications Report", commercial 5G [...]
