All the electronic products have to use PCB to function, so there is a consensus that the trend of PCB market almost indicates the dynamic of the electronic industry. With the development of phone, laptop and PDA and the other advanced, small-sized electronic products like the wearable devices, the demands for flexible printed circuit boards are increasingly growing. PCB manufacturers are focused to create thinner, lighter and higher-density FPC to seize this thriving market. Under the background, I consider it necessary to write about the differences between single-sided flex PCB, double-sided flex PCB and multilayer flex PCB, whether for the PCB fabricators or the open source hardware makers who are likely to buy

We met lots of Elecrow Japanese customers face to face during the Maker Faire Shenzhen, and found some interesting projects. It's really exciting and amazing to see so many customers at one time. I will show you the photos and some simple introduction of the projects. Part One- Visiting Maker Faire Booth

When a PCB layout and routing is completed and both the connectivity and spacing are inspected without faults, does it mean the PCB design is succeeded and finished? Of course no. A final inspection is often ignored or neglected by some new engineers, this is likely to result in some bugs or problems in prototyping or even re-prototyping, such as the sockets getting too close, or loop signal and so on. Therefore, a final inspection is a must-do thing of PCB layout. A good final inspection process involves lots of specific steps, here listed some steps that I found quite important but easy to be ignored. 1.Footprint 1). Pads spacing. For the new components, it’s necessary

Christmas is the most important festival for many people. As a maker or electronic engineer, how can we celebrate Christmas in our own special way? Before Christmas 2016, we held a Christmas PCB Contest in Elecrow facebook group, there were several fascinating projects. As we did before, Elecrow provided

November 01, 20171.Anti-electromagnetic interference issue should be more careful with the following systems 1）The system that the microcontroller clock frequency is particularly high and the bus cycle is particularly fast. 2）The system contains high-power and high current drive circuit, such as the relay with a spark, high current switch and so on. 3）The system with a weak analog signal circuit and high-precision A / D converter circuit. 2. Measures to improve the anti-electromagnetic interference of system 1）Choose the low-frequency micro-controllers. The use of low external clock frequency micro-controllers can effectively reduce the noise and improve the system's anti-jamming capability. The square wave and sine wave at the same frequency, the
