More than a hundred years have passed, and the history of human communication is still constantly evolving. We are surrounded by various communication information every day, such as broadcasting, mobile phones, wireless communication, navigation, remote sensing, etc., constantly filling our world and becoming a part of our lives. The reason why they can serve us normally is not only because of modern advanced network technology, but also because of the important medium of communication - antennas.
An antenna is a transformer that transforms guided waves propagating on a transmission line into electromagnetic waves propagating in an unbounded medium (usually free space), or performs the opposite transformation. It is a component used in antenna equipment to transmit or receive electromagnetic waves. Any communication equipment that requires electromagnetic waves to transmit information relies on antennas for operation. For some non signals that require electromagnetic wave transmission, their energy radiation also requires antennas. Antennas are the key to the entire communication LAN. Once a problem occurs, the entire area will lose signal connectivity, and the entire area will fall into chaos.
Antennas have a wide range of applications and may be used in various environments, therefore they have high requirements for themselves. In order to ensure the normal operation of the antenna, it is necessary to ensure its reliable quality, whether in the selection of antenna materials or the production process of the antenna, it must be firmly controlled.
Ordinary circuit boards cannot match the basic performance of antennas. Currently, ceramic circuit boards are the most suitable for antenna requirements. Ceramic circuit boards have multiple advantages, mainly reflected in:
1. Low dielectric constant, low high-frequency loss, and more complete signal transmission;
2. A stronger and lower resistance metal film layer. The bonding strength between the metal layer and the ceramic substrate on the product is high, with a maximum of 45MPa (greater than the strength of the 1mm thick ceramic plate itself); The conductivity of the metal layer is good, for example, the volume resistivity of the obtained copper is less than 2.5 × 10-6 Ω. cm, generates less heat when current passes through;
3. Good insulation performance. The antenna in use will generate high voltage, which is already a very dangerous presence. Ceramic circuit boards have good insulation and can withstand breakdown voltage up to 20KV/mm, effectively ensuring personal safety and equipment protection ability;
4. It can be assembled with high density. The line/spacing (L/S) resolution of ceramic circuit boards can reach 20 μ m. Thus achieving short, small, lightweight, and thin communication devices.
Sliton collaborates with many domestic communication industry clients and produces ceramic circuit boards for antennas, which is one of them. Sliton adopts the national invention patent laser activation metalization technology for production, continuously creating high-quality products. The company's market is expanding day by day, and its scale is constantly expanding.
The communication industry is developing rapidly, and with the arrival of the 5G era, it has caused greater market competition. In order to consolidate their position, major communication companies are constantly innovating. This is a game that exists not only among large enterprises, but also for small and medium-sized enterprises. If they can seize the opportunity, they will also usher in their own spring.
