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

irregular, rule and grid. (1) Irregular Arrangement The axis directions of components are inconsistent with each other, which is convenient for layout of printed wires, and the plane utilization is high and the distribution parameters are small, which is especially beneficial to high-frequency circuits. PCB Resources Network-p c B resource Source Network(2) Rule Arrangement The axes of components are arranged in the same direction, and the layout is

also very importantThere are mainly two points: one is the drilling position, the second is the size of the drill holePCB generally have two pad layer (the top floor, the inner layer is no pad, because there is no way to install components), a drilling layer. The solder pads and drilling layers are completely different concepts, the solder tray layer points out the need to install components of the pad shape position, the drilling layer is to locate and define the location of the hole.PCB

Autocam Automation platform, front-end management orders, the back end of the task, the front-end UIL interface has board thickness, copper thickness, plate, surface treatment, layers and other information, And this information is not after the end of the end of the information needed. Take the bore hole compensation, the back end needs is the borehole compensation value, but the front end does not have this information, wants to get this drill hole compensation value is through the Multidimensi

(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): (

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

The PCB designer should select the correct network table based on the principle diagram and the features of the PCB design tool to create a network Table meeting the requi
