High-frequency high-speed PCB –5G core benefit PCB

As we all know, PCBs has many types according to different categories. However ,among all the PCB categories and PCB types, there are two types of PCB boards, which will benefit greatly from 5G applications 1. High frequency PCB board The high frequency PCB i s mainly used in the antenna and RF front end. In addition, the CCL of the high frequency PCB uses high frequency materials (PTFE and hydrocarbon) and FR-4,because the high-frequency material is softer than the FR-4 material. the consistency of the mixing process is poor,the production difficulty is increased, and the price and profit margin are higher. However, many high-speed boards used for 5G are high multi-layer PCB boards, especially the backplane PCB of the core network is even higher than 20 layers ( general PCB is 4,6,8 layers ), which can make the data rate  increase and smaller size for the base station What's more, the line width and line spacing are further refined, and the technical difficulty is naturally higher   2....

The Factors That We should Consider About Power Processing In PCB

The processing of the power plane plays an important role in PCB design. In a complete PCB design project, usually the power supply process determines the success rate of 30%-50% of the project Today, let's talk about the basic elements that we should  consider in the power plane processing during the PCB design process. 1   When doing power processing, we should first consider its current carrying capacity,which includes two aspects: a) Whether the power line width or the width of the copper is sufficient to consider the power line width The first step is to understand the copper thickness of the layer on which the power signal is processed. However, under the conventional process, the outer thickness of the PCB (TOP/BOTTOM layer) is 1OZ (35μm), and the inner copper thickness is 1OZ or 0.5OZ according to the actual situation For 1OZ copper thickness, under normal conditions, 20mil can carry about 1A current. But,  for 0.5OZ copper thickness, under normal circumstances,...

Introduction of PCB Vias & PCB Holes

1   Via design in high speed PCB In high-speed PCB design, multi-layer PCBs a r e often required. H0wever, vias are an important factor in multilayer PCB design. The via holes in the PCB a r e mainly composed of a hole, a pad area around the hole, and a POWER layer isolation area. Today, let's talk about the vias of PCB  and design requirements for vias in high-speed PCBs. In high-speed PCB multi-layer boards,signals a r e transmitted from one layer of interconnect to another and via vias a r e required to connect. And also,when the frequency is lower than 1 GHz, the via can play a good connection, However, when the frequency is higher than 1 GHz, the influence of the parasitic effect of the via on the signal integrity can not be ignored. At this time, the via appears as a discontinuous breakpoint on the transmission path which will cause signal reflection, delay, and attenuation....

Development of Flex PCB (FPCs) and substrate-like pcb (SLPs) in PCBs

Nowadays, as we all know, the development of mobile phones is becoming more and more intelligent, thin and light which means that the internal components of mobile phones will be further reduced or integrated. Under this trend, flex pcb  (FPCs) and substrate-like pcb (SLPs) in PCBs have the opportunity to be further promoted and applied. At present, FPC has grown to RMB 31.6 billion in the Chinese market. It is estimated that by 2021, China's FPC market will have an opportunity to reach RMB 51.6 billion with a compound annual growth rate of 10%. And today's mainstream Chinese brands of mobile phones use FPCs in 10 to 15 pieces,while iPhone X uses up to 20 to 22 pieces. We can see that there is still much room for improvement in the use of FPCs in Chinese smartphones market. At the same time, the FPC single value has reached 10 US dollars, the amount is still rising. However, FPCs...

The Commercialization of 5G Application in PCB industry

With the construction and commercialization of 5G, we can expect that communication electronics and automotive electronics will become the new kinetic energy to drive the development of the PCB industry from 2019 to 2021. In fact, while 5G brings opportunities to the PCB industry, it also puts higher and more stringent requirements on PCB technology, whose stands in terms of speed, integration, heat dissipation, frequency, and multi-layering are much higher than 4G. Due to the high frequency microwave characteristics of 5G,the base station density is higher than that of the 4G base station. However, the processing frequency, data transmission and processing speed of various devices are much higher than the 4G era What's more,these core  devices, transmission devices, and antenna/RF devices place very high requirements on high-frequency, high-speed PCB boards Mainly reflected in four aspects 1) The base station RF unit and antenna have undergone major changes in structure and function, mainly because the number of radio unit channels...

5G Mobile Phones Are Coming Soon !

5G was officially licensed in the first half of 2019,and the overall layout of the smart mobile phone industry will be earlier in advance. However, people expect that  the operator's 5G package is going to appear officially on the market in the fourth quarter of 2019. The sales of 5G mobile phones in 2019 may be relatively small. At the same time, the 5G module  expect to launched from high-end products. In addition, some people believe that from the beginning of 2020, 5G mobile phones will appear on a larger scale in the high-end models of various brands. What's more, the sales of 5G mobile phones in 2020 will be higher than 75 million according to a industry report which is more than 20% of the total sales in 2020 .However, If the price of 5G mobile phones  can reach 2,000 yuan by the end of 2020, which will definitely promote the sales of 5G mobile phones to further increase.

The World’s history of PCB development and the history of China’s PCB development !

 01 World's history of PCB development In 1936, the founder of printed circuit board, Austrian Paul Eisler, first used printed circuit boards in radio installations. In 1943, Americans used the this PCB technology in military radios. However,in 1947, the US Aviation Administration and the US Bureau of Standards launched the first technical seminar on PCBs. In addition, In 1948, the United States officially recognized the invention of the pcb technology and used it for commercial purposes. In the early 1950s , due to the fact that problem of the bonding strength and weldability of copper foil and laminates of CCL has been solved, the performance of PCB became stable and reliable. And industrialized mass production of PCBs came into reality soon Copper foil etching technique became the mainstream of PCB manufacturing technology and started production of single-sided PCB boards In the 1960s, hole metallization was achieved, and double-sided PCBs were mass-produced In the 1970s, multi-layer PCBs developed rapidly and continued to develop in the direction of...
