Fritzing is a set of software designed for PrintedCircuitBoard printed circuit boards. It is a tool especially intended for designers, artists, researchers, and amateurs. Like Processing and Arduino, Fritzing developers design this software in the spirit of openness, simplicity, and sharing. Fritzing is a simple and easy-to-use

Label: des HTTP ar strong data SP Div 2014 CPCB design, especially high-frequency and high-speed design, will inevitably involve the calculation and setting of PCB-related parameters, such as via overcurrent capacity, via parasitic capacitance, impedance, etc, the current carrying capacity of the wire, crosstalk between two coupling signal lines, wavelength and o

speed up the product market, many manufacturers now prefer to use special EDA tools to achieve PCB design. However, specialized EDA tools cannot produce ideal results or reach a 100% distribution rate. They are messy and usually take a lot of time to complete the rest of the work.Nowadays, there are many popular EDA tools and software on the market. However, apa

Flexible Circuit BoardsOur company plans to use flexible circuit board design to solve the problem of signal transfer and circuit board interconnectivity in small imaging systems. Does the rigid-flexible board design require special design software and specifications? In addition, where can I process such circuit boar

ability to upgrade and swap parts. The System Function Square diagram provides a basis for separation. For example, a computer can be divided into a motherboard, a display card, a sound card, a floppy disk drive, and a power supply.Determine the encapsulation method and the size of each PCB.When the technology and number of circuits used by each PCB are determined, the next step is to determine the size of the Board. If the

ObjectiveThe last two days using AD14 software designed a Bluetooth anti-loss circuit board (PCB) drawings, the middle of some details in this document, to facilitate the next design of the PCB reference. Also hope to give the layman's classmates or just into the students a macro view of the General circuit board

Circuit Design: This is a very big concept, from the voltage intensity can be divided into strong electric circuit design and Weak Current Circuit Design; from the design tool can be divided into manual drawing and electronic auxiliary design, the circuit types can be divide

With the help of software, you can go to linux for PCB-general Linux technology-Linux programming and kernel information. The following is a detailed description.

improper, it will also be disturbed by other signals, always EMC is a topic frequently discussed in PCB layout and wiring. For line width and line spacingFor the line width, the first step is to understand the minimum width of the processing process to avoid the failure of the PCB designed by myself. Generally, 10mil is used, which is basically greater than 4mil, while the power supply part, A separate pow

In this article, we will discuss the PCB cabling design methods and requirements. The layout design of components and the direction of electrical connections may produce different results, and the results may vary greatly, therefore, the structure of printed circuit board components should be correctly designed and the correct

Although semiconductor integration is becoming increasingly high, many applications also have ready-to-use on-chip systems, while many powerful and out-of-the-box boards are becoming more accessible, but many use cases of electronic products still require the use of custom PCBs. In one-off development, even a common PCB can play a very important role. The PCB is the physical platform for the

Despite the increasing integration of semiconductors, many applications also have ready-to-use on-chip systems. At the same time, many powerful and out-of-the-box development boards are increasingly accessible, however, in many use cases, the application of electronic products still needs to use custom PCB. In one-time development, even a general PCB can play a very important role.

If you participate in this year's Autodesk developer day, you will be very much looking forward to the release of AutoCAD. Now it is coming ~~ On October 11, December 6, Autodesk Ltd. ("Autodesk" or "Autodesk"), the world's leader in 2D and 3D design, engineering and entertainment software, held in Shanghai, "born on the cloud, to serve China "otsk cloud strat

verify Sometimes, the network relationship of the painted board is different from that of the schematic diagram due to misoperations or negligence. In this case, it is necessary to check the network. Therefore, after the painting, you cannot rush to hand it over to the plate manufacturer. You should first check it before proceeding with the subsequent work. How Should PCB design and mechanism
