(1) Error One In the schematic of the electrical connection, must appear red fork, otherwise not counted electrical connection: The following figure: (1) Error two The same network designator, on behalf of the electrical connection, when placing the net network designator, also should pay attention to, appear red fork to calculate electrical connection (1) Error three When making the schematic library, manually draw the schematic elements, note that the pin cross-out (otherwise all errors): (

Linux-based schematic and PCB, Linux-based schematic PCBLinux schematic and PCBThe famous Allegro and the classic Protel 99SE in Windows do not support the Linux operating system. To develop a Linux driver, you must check the principle diagram and PCB.There are three common practices:1. The host uses the Windows system and installs Linux in virtual machines such as VMWARE so that you can use the software in Windows to view the schematic diagram and

the Design Cache folder, select the component that you just modified, right-click Select Update Cache , go all the way to update the component in the schematic diagram.6) Some details:The magnification and reduction of the drawing schematic is the difference between the button "I" (zoom in) and the "O" (Zoom Out) and the Protel, in the creation of the component package, in addition to GND can have the same name, no other pin, no error, but seemingly error has no effect, Because the OrCAD comes

Objective: To add a logo to an enterprise design or personal work Tool used: alicloud desinger 6.6 Photoshop Background: The black and white images required in the operation are not black and white images that appear. But the file storage method is only black or white. You can edit the image file to open it. The image storage depth is 1 bit. Procedure: 1.

PCBDesign Process Reprinted from: http://www.pcbhz.com/html/Services/pcbsj/pcblc/ First, make preparations. This includes preparing the component library and schematic. In progress PCB Before design, prepare the schematic diagram. SCH Component Library and PCB Component Library. Component Library can be used Peotel It is difficult to find a suitable library, but it is best to

From http://blog.mcuol.com/User/luozhen0810/Article/9700_1.htm Printed circuit boards (PCB) appear in almost every electronic device. If there are electronic parts in a device, they are all mounted on PCB of different sizes. In addition to fixing all kinds of small parts, the main function of PCB is to provide the electrical connection between the above parts. A

When you use PCB layout, you can refer to these materials to draw a high-quality PCB. Of course, you can also

manager. The following is a practical design case to introduce the operation of the internal electrical layer. Please first build a PCB design file or open a ready-made PCB design file. In the PCB editor, execute the "Design" | "Layer Stack Manager" command to open the layer stack manager. Click to select the signal l

Toplayer (top) Draw the line is red, is the general double-sided board on the upper layer, single panel can not use this layer.The Bottomlayer (bottom) line is blue, which is the line above the single panel.MidLayer1 (middle layer 1) This is the first layer, as if there are 30 layers, the general design staff can not use, you do not have to control him, multi-panel time use. The default is not displayed in 99SE and is not available.Mechanical Layers (mechanical layer) (purple red) used for label

Sinox, Macau, China many platform CAD graphics, PCB board, IC I know, HDL hardware description Language narrative, circuit simulation and design software, elemental analysis table, can open the eyes of the world.Recent research Sinox the implementation of Windows edition Protel,powerpcb,autucad, which is considered very cumbersome. On the other thought, Sinox the following in fact there are a lot of auxiliary design software available, but we do not k

Design processA. Creating A network table1. Network table is the schematic and PCB interface files, PCB designers should be based on the use of schematic and PCB design tool characteristics, choose the correct network table format, to create a network table that meets the requirements.2. In the process of creating a network table, you should actively assist the s
