5G concept fire PCB material group fever

Timing has entered the traditional peak season of the PCB group, and the start-up of pulling goods has driven manufacturers' performance to rise. The legal person said that the benefits of 5G communication technology are gradually showing, whether it is still under development, proofing, certification, or related high-frequency materials have been shipped one after another. In order to take the lead, all major factories are actively deploying. Among them, CCL (copper foil substrate) is an important material for PCB. With the improvement of process technology, relevant CCL manufacturers will be the first beneficiaries. Taiyao has been actively developing high-frequency and high-speed products in recent years, including Netcom, servers, base stations, etc. A few days ago, foreign investment reports even pointed out that it is optimistic that the era of high Internet speed will drive the demand for CCL to increase sharply.

The Sino-U.S. trade war is intensifying, and it is not easy to resolve in the short term

The Sino-U.S. trade war has intensified. Although the Sichuan-Xiwei hotline is expected to take place at the G20 summit in the near future, there are deep trade differences between the two sides and it is not easy to resolve them in the short term. Next year, focusing on the 5G infrastructure construction of telecommunications companies in various countries is a relatively safe investment direction in this uncertain era. Among them, in the 5G base station construction business opportunity, PCB (printed circuit board) specifications will be greatly improved, and those who can develop high-specification PCBs will benefit. Observing the development schedule of 5G spectrum in various countries, South Korea, Japan, China, and Europe will release the frequency band between 3GHz and 6GHz in the first half of 2019, which is the highest compared to 4G.

With the continuous advancement of technology, the quality control of the internal PCB circuit boards is becoming more and more stringent.

With the continuous advancement of science and technology, the continuous improvement of people's living standards, the continuous development of smart phone technology and wearable electronic technology, intelligence, thinness, and miniaturization have become the mainstream, and consumers will have higher and higher product quality requirements. Therefore, as a laser marking machine manufacturer, the quality control of the internal PCB circuit board is becoming more and more stringent. It must be better to win consumers, win the recognition of customers, and achieve secondary purchases, such as Apple, Huawei, etc. Technology leader. PCB is one of the important components of the electronics industry. The industrial output value accounts for about a quarter of the total output value of electronic components.

Technology Sharing: Steps for PCB Recycling

Any item will be damaged if it is continuously used, especially electronic products. However, the damaged items are not completely waste and can be recycled, and the same is true for PCBs. Moreover, with the advancement of science and technology, the number of electronic products has increased sharply, shortening their use cycles, and many products are discarded without being damaged, leading to serious waste. Products in the electronics industry are updated very quickly, and the number of discarded PCBs generated therewith is also very staggering. Every year, there are more than 50,000 tons of discarded PCBs in the UK, and as many as 100,000 tons in Taiwan. Recycling is the principle of resource conservation and green production. Moreover, there are some

Three special routing techniques for PCB: right-angle routing, differential routing, serpentine routing

Layout is one of the most basic work skills of pcb design engineers. The quality of the wiring will directly affect the performance of the entire system. Most high-speed design theories must be finally implemented and verified through Layout. It can be seen that wiring is very important in high-speed PCB design. The following will analyze the rationality of some situations that may be encountered in actual wiring, and give some more optimized routing strategies. It is mainly explained from three aspects: right-angle wiring, differential wiring, and serpentine wiring. 1. Right-angle routing: Right-angle routing is generally a requirement to avoid as much as possible in PCB wiring.
