Ceramic PCB welcomes 5G, those base stations in those years
my country has strict technical limits on electromagnetic radiation, and rumors about base stations will soon be undefeated. In fact, electromagnetic radiation is widespread in people's lives, and the radiation of many household appliances far exceeds that of base stations. In the 5G era, base stations will choose better hardware materials for deployment, and the number is expected to increase tenfold.
Earlier, the NetEase News Center reported such a news that it was said that the communication base station of the community was demolished, the owners collectively "lost connection", the telephone could not be connected, and the network signal was poor, not to mention how inconvenient it was.
Why do the owners insist on dismantling the base station? It’s not about the ‘big base station’s radiation’. In fact, take the most basic 2G base station as an example. The power density of the first 10 meters of the antenna is 0.6 microwatts/square centimeter. The actual radiation of the hair dryer used by people reaches 100 microwatts/square centimeter, which is more than a dozen. The disparity of times is ignored intentionally or unintentionally.

In comparison, the radiation of a mobile phone is actually greater than that of a base station. After all, the base station is outside the house, on the top of the floor, and the phone that makes a call is pointed to the head against the ear. What are the consequences of dismantling the base station? The community property has posted an announcement explaining the impact, causing problems such as weak signal, inability to dial or answer, poor call quality, easy to drop, and inability to access the Internet... Basically, it means bidding farewell to civilized society, and the owners regret it.
This kind of base station rumors will not deceive more people, because we are in a transitional stage of 4G to 5G mobile Internet, 5G standards have been set, the number of domestic base stations in China is no longer as simple as doubling, it is expected to be It is more than ten times the number of base stations that have been deployed today, ensuring that the hottest downtown area can also be quickly connected to the Internet, and that there is also signal interaction in the most desolate corner of Saibei.
In order to ensure smooth and convenient communication, in addition to the number of base stations, the quality of information upload and download is also very important, and base stations need to be operated for a long time, which will directly affect the difficulty of repair and maintenance, and the service life of materials must also be considered. . From the perspective of signal transmission, ceramic-based PCBs are the first choice for signal HI-FI (high fidelity). Compared with other organic material substrates and the usual aluminum-copper substrates, ceramic PCBs have a lower resistance and more stable metal layer, and small current flow. High thermal conductivity, with these characteristics, can more effectively ensure the circulation and dissemination of electrical information. The service life and maintenance difficulties that operators are concerned about are also optimally answered. Since the thermal expansion rate of ceramic PCB s is closer to that of silicon chips, it can avoid desoldering caused by excessive temperature and temperature differences. Because ceramic PCBs do not contain organic materials, It is more suitable for a variety of environments.
The use of the best materials for base stations will speed up people's convenient life. The 5G era is imminent. As a member of the new era, you should experience technology, understand technology, and enjoy technology, so that the base station news of those years will not repeat itself.
