China has become the world’s largest PCB Producer

Under the overall trend of the global PCB industry shift to Asia, China, as a major electronics manufacturing country, has attracted a large number of foreign and local PCB companies to invest in a huge domestic demand market and relatively low production costs, and promoted the Chinese PCB industry in just a few years. Explosive growth. At present, China has become the world's largest PCB producer and one of the regions in the world that can provide the largest PCB capacity and the most complete product types. On the whole, although the number of local PCB companies is large, there is still a certain gap between the size and technical level of the enterprises and the foreign-funded enterprises that set up branches in mainland China, and the competitiveness is slightly weak. From 2008 to 2016, the output value of China's PCB industry increased from US$15.037 billion to US$27.24 billion, with a...

Introduction of the welding method for PCB production process

Welding refers to the manufacturing process and technology of joining metal or other thermoplastic materials by means of heating, high temperature, high pressure, and the like. Welding is a very important process in PCB production. If there is no soldering, the various devices cannot be concentrated on the board, and the so-called circuit board cannot be formed. There are many different welding processes, so let's take a look at what is common. 1. Arc welding Arc welding, which uses arc heat to melt the workpiece to achieve the connection. Arc welding is a common type of welding method. There are two basic types, one is the melting pole arc, the electrode is melted by the arc heat, and the molten electrode metal passes through the arc to the molten pool. The other is a non-melting arc, the electrode does not melt, and the filler metal needs to be added separately to the...

Global Memory Card Market: China’s memory technology ranks second

DRAMeXchange, a memory card industry research organization of TrendForce, recently released the 2014 global memory market statistics report, and ranked the top ten vendors. The second one is likely to surprise many people. In 2014, the global memory industry total sales of 8.8 billion US dollars, a 21% year-on-year increase. This is mainly due to the stability of PC DRAM memory grain prices and the growth of cash-related trade-related contracts. Due to the shortage of market supply, control of supply and demand, coupled with the rapid growth of the smartphone and server markets, the memory industry in 2014 is still very profitable, and the price of memory chips throughout the year is also very stable. The average contract price and market of 4Gb DDR3 The price was 3.65 US dollars, 4.00 US dollars, an increase of 18, 17%, the difference between the two is only 10%. On the vendor side, Kingston was the...

Introduction to Rigid-flex PCBs

Introduction Rigid-flex PCB is a special integrated circuit board combining with rigid and flex circuit layers. It is mixed one or several rigid area and flexible area, then is laminated together to be an integrity circuit board. Advantages and characteristics To meet 3D assembly in the small space, we need Rigid Flex PCB to have both rigid and flex circuit layers, witch can make it to be multi-layer PCB offering support force for electronic components assembly and installation. It owns excellent electronic product installation. In addition, the rigid section and the flex section are laminated together, so it has good stability, even under the harsh environment, won’t degrade the performance. With the feature of bending and folding like paper, Rigid Flex PCB can optimize the available design space. Application area Rigid-flex PCB produces are mainly applied in: aviation, aerospace, unmanned aerial vehicles(UAVS),medical devices, smart phones, cameras, digital cameras, tablets, wear electronic, Bluetooth movement headset, VR,...

How to decided a trace width?

A few gerber that we recieved,the trace width was not enough to build,many engineers unsure how to set up the trace width. Width is regularly decided by the current signal carries,for a minimum width RCYPCB would recommend more than 4mil,if you have to design any fineline in PCB,you can set the finelins down to 3mil,but please try to set the trace width as bigger as you can. The bigger trace width is helpful smooth production,the fineline will cause higher failure rate in manufacture and higher costs in purchasing. For the thin trace width,you can add teardrops to the connections of tracks and pads.Teardrops are useful for high voltage/amperage traces. Anyway,PCB layout practice is a difficult subject to talk about because there are so many  rules, regulations and standards ,so please comply with the different rules, regulations and standards when you design different PCB. ...
