Experience on the related features of various PCB material series

Previously,I have mentioned the brand information of PCB material manufacturer(South Asia, Taiguang, SY, Lianmao, Tenghui, Taiyao, Hongren, Hezheng, KB, Isola) and so on. Now let's talk about the relevant characteristics of various series of PCB material today 1. Normal FR4 material: The Tg point is generally around 150 degrees, which belongs to the normal processing substrate, and there is no special material. 2. Halogen-free materials:there are added fillers in the board, the board is relatively hard and crisp,the processing needs to have corresponding parameters 3. LOW CTE material: the coefficient of thermal expansion is relatively low, but the reliability is better 4. High TG FR4  material: Tg point is relatively high, generally corresponding to 170 degrees or more, high hardness, difficult to process 5. Low DK material: an emerging material,DK value and DF value is relatively low,generally it is used in high-end products   ****** We are one of the most trusted PCB factories and Rigid-Flex PCB manufacturers in China. Specializing in the production...

5G base station construction, high-speed development of new energy vehicles

At present, the automotive industry is repeating the development trend of the smart phone industry,which is from functional vehicles to smart and intelligent vehicles. On one hand, with a big sales growth in new energy vehicles, the degree of automotive electronics is constantly increasing. On the other hand. according to statistics, the cost of electronic devices used in vehicles has accounted for about 20% of the total cost of the whole vehicle,and the high-end vehicles have reached 50% or even 60%, while the cost of automotive electronics for pure electric vehicles has reached 65%. It is reported that in 2018, the sales volume of new energy vehicles was 1.256 million units, an increase of 61.7% year-on-year. The sales volume of passenger vehicles was 1.01 million units, an increase of 83% year-on-year, higher than market expectations.With the rapid growth of new energy vehicle sales and the increasing degree of automotive electronization / automotive electronics,which will...

5G commercial license, issued today!

CCTV News: Ministry of Industry and Information Technology issued 5G commercial license today According to  Global Times reporters from the Ministry of Industry and Information Technology, at present, global 5G is entering a critical period of commercial deployment. And also insisting the combination of independent innovation and open cooperation, China's 5G industry has established a competitive advantage.Besides, 5G standard is a unified international standard, The standard required patents declared by China account for more than 30%. In the technical test phase, many foreign companies such as Nokia, Ericsson, Qualcomm and Intel have been deeply involved. With the joint efforts of all parties, China's 5G has a commercial foundation. After the Ministry of Industry and Information Technology issues a 5G commercial license, China will officially enter the 5G commercial year. As always, we welcome domestic and foreign enterprises to actively participate in China's 5G network construction and application promotion, and share China's 5G development results.  ...

Technology | Three Reasons for PCB Copper Peeling

The peeling of PCB copper wire  (also often referred to as copper falling off) means poor process in pcb manufacturing,  and the PCB factory said that it is a laminate problem, requiring its production plant to bear the losses. According to customer complaint handling experience, the common reasons for copper falling off in PCB factory are as follows:   First, the PCB factory process factors 1. Copper foil is excessively etched,The electrolytic copper foil used on the market is generally one-sided galvanized (commonly known as ash foil) and one-sided copper plating (commonly known as red foil).The common falling off copper  is generally galvanized copper of 70 um or more When the customer circuit is designed to pass through the etched line, if the copper foil specification is changed and the etching parameters are not changed, the residence time of the copper foil in the etching solution is too long.Because zinc is originally a lively metal, And also,when...

International copper prices fell to low point this year, PCB industry prospects with conservative view

The international copper price spot price fell to 5,822 US dollars per metric ton in May, the second lowest this year. Besides, as far as the PCB industry is concerned, it shows a wait-and-see attitude towards demand in the second half of this year  and has a conservative view on inventory preparation. And also, the international copper price fell by 6.3% in May, and the latest offer fell to US$5,822 per metric ton, which is the second lowest this year, it has meaning or significance of two aspects. First, the global industry prospects is declining. On one hand, it caused infrastructure construction demand for  electric wires and cables to decline. On the other hand, it reflects the decline in the demand for related copper foil and copper foil substrates in the PCB industry or PCB factory. In addition,  the US-China trade war has deteriorated, and it caused market uncertainty to rise. However, even though, the PCB industry has responded cautiously to market changes   **********We are one of...

PCB industry is upgrading,PCB market of the global 5G base station in 2019 is expected to reach 1 billion US dollars

In April 2019, South Korea and the United States launched 5G mobile communications Projects. Although the initial signal coverage rate was not satisfactory, it also indicated that the 5G era is coming. In the second half of 2019, UK and Mainland of China will also officially move toward 5G field,which will start a long-time competition for 5G business opportunities Analysis PCB business opportunities driven by 5G mobile communication can be roughly divided into several types, First of all, 5G base stations infrastructure,due to the physical characteristics of micro-waves, 5G requires 4 to 5 times the number of 4G base stations and a large number of small base stations. Then there will be a variety of switches, routers or home communication equipment updates, and finally a variety of 5G applications.Various types of system modules will require PCB support with different characteristics. In terms of 5G base stations, the AAU of each 5G base station has about six PCBs (3...

RoHs Lead Free

RoHs (Restriction of Hazardous Substances Directive 2002/95/EC) is an environmental directive (but not a law) passed by the European Union in February 2003. The basic principle of RoHs is that from July 1st, 2006, all electronic devices introduced into the market must not contain lead or certain other harmful substances. This applies to the following products: Household appliances IT and telecommunication equipment Consumer electronics Lighting devices Electrical and electronic tools (except for large, stationary industrial devices) Toys, recreational and sporting articles Vending machines Due to environmental issues,RCY provides service of manufacture printed circuit boards without lead for surface finish that requires rigorous concentration of 6 hazardous substances including Lead (Pb), Mercury (Hg), Cadmium (Cd), Hexavalent Chromium (CrVI), Polybrominated Biphenyls (PBB) and Polybrominated Diphenyl Ethers (PBDE). Among the 6 types of substances, lead is the most widely applied in the electronic plating. Therefore, lead-free is the best way for surface finish of PCB. Attached our Certificate of...
