What is the PCB value of the 5G base station?

PCB global production value is currently about 63.5 billion US dollars, while mainland China has more than 50% of the output value and this proportion will continue to rise with the growth of domestic factories. In addition, 5G construction, consumer electronics, and automotive electronics and other aspects of the PCB in the 5G pull the new market The price of PCBs for 5G base stations has doubled,which strongly drives the demand for PCBs. We estimate that the PCB value of a 5G base station is about 12,500 yuan,which is about 3 times that used by previous 4G base stations However,the downstream consumer electronics of 5G ,let's say, smart mobile phone market deeply affected by 5G. And the penetration rate of FPC and SLP will continue to increase.Under the general trend of 5G, mobile phones that are still in the 4G era will face major changes in internal structure The power required for 5G mobile phones will be larger than that...

Manufacture of high-density multi-layer Rigid-flex PCB boards

In order to meet the low-cost, high-density requirements of consumer-grade rigid-flex pcb boards, at present, people have already developed several new processing technologies for rigid-flex pcb in the market.        Figure 1   As shown in Figure 1,this new processing technology uses a buried or inner microporous structure to optimize the space of the inner conductor layer. However, the via hole processing for the inner layer is the same as the via hole processing for the double-sided flexible board. In addition, we  usually recommend to use a cast or laminated non-adhesive substrate for the material which can reduce the drilling waste and ensure the good performance of the rigid-flex pcb under various high temperature process conditions for rigid-flex pcb    ...

Let’s Talk About Industrial Grade Rigid Flex PCB With High Density

As we all know,HDI rigid-flex pcb boards, the rigid-flex pcb which has high-density wiring design with fine circuit and microporous structure have not been used in aerospace products. Because many people consider that they are  not sufficiently reliable under harsh environmental conditions And also,people can only use the conventional soldering means to mount the terminal components on this PCB. However,many companies already have begun to use this HDI rigid-flex pcb boards with both high-density design and high reliability in industrial electronics  and medical electronics products. A new design concepts and installation methods of HDI rigid-flex pcb for terminal products have emerged In addition, on this high-density of rigid-flex pcb,the general line spacing is less than 100 um and the hole aperture is less than 100 um,and we use the 25um thick or even thinner non-adhesive thin copper polyimide CCL What's more,  the rigid-flex pcb copper thickness is mostly 18um or less, and we use laser drilling technology to process the Micro-holes, especially the laser blind hole technology often used...

About IC-Substrate board ,There is something you should know

From the perspective of the main business of global IC Substrate board leading enterprises, the majority of the development from the PCB business. At present, from the perspective of the global IC Substrate board , there are three main types: 1) Developed by PCB companies Since the package substrate is developed from high-order HDI boards, both of which have a common expenditure on the manufacturing process. However,many PCB manufacturers can extend the development of the IC Substrate board business. Such as Xinxing Electronics (a subsidiary of UMC) in Taiwan, South Asia and Huatong Computer, etc. South Circuit and Xingsen Technology also belong to this category 2) Developed by the packaging factory In addition,theIC Substrate board is also a kind of packaging material, and the packaging factory will also develop upstream in order to reduce costs and attract customers. 3) Pure IC Substrate board companies The IC Substrate board has a high threshold and has great potential for...

RCY ELECTRONIC : Analysis of PCB Industry

As we all know,there are many kinds of raw materials we need to use for PCB manufacturing industry. For example, mainly copper clad laminates, prepregs, copper foil, copper balls,  inks, dry films and other materials. However,  CCL is the basic material for making printed circuit boards, and companies can  only use the CCL in the manufacture of printed circuit boards. And ,the two have strong relationship of interdependence. On one hand ,the manufacturing technology and supply level of CCL is an important foundation for the development of the PCB industry. On the other hand,the development of PCB will also have an important impact on the demand and development of CCL What's more, we can see that CCL accounts for about 20% to 40% of the total printed circuit board production cost, and has the greatest impact on the cost of printed circuit boards. In addition to copper clad laminates, copper foil and copper balls are also important raw materials for PCB...

Automotive PCB Supplier-RCY ELECTRONIC : A brief introduction of FPC ( Flexible Printed Circuit )

1     Definition of Flexible Printed Circuit FPC , fully name is Flexible Printed Circuit, also known as Flexible Printed Circuit board, is referred to flex pcb. It is made by using a image pattern transfer and etching process on a flexible substrate surface to form a conductor circuit pattern. However, we can divide FPC ( flex pcb )  into single-sided flex pcb , double-sided flex pcb multi-layer  flex pcb and  flex-rigid pcb   2     Features of Flexible Printed Circuit FPC is short, we can shorten assembly time to eliminate the need for redundant cable connections FPC is small, flex pcb has smaller size than rigid pcb,which can effectively reduce the volume of products to increase the portability In addition, FPC is light,flex pcb has lighter weight than  rigid pcb,which can  reduce the weight of the final electronics What's more, FPC is thin, flex pcb  has thinner thickness than normal rigid pcb,and thinness can improve softness and flexibility   3    Advantages of flexible circuit boards Flexible...
