PowerPCB usage tips POWERPCB application tips - Quickly delete copper foil A quick way to quickly delete the ground or power copper foil that has been defined and filled with copper: Step 1: Move the copper foil frame to be deleted out of the board. Step 2: Re-copper the copper foil frame that has been removed from the board. Step 3: Redefine the network of the copper foil frame as none, and then delete it. For large PCB boards, it can be deleted in a few minutes, but it may take several hours if the above method is not used. Now the data structure of balzeroute is more reasonable than powerpcb, and some power and ground network deletion work can be done in balzeroute. You may as well give it a try. POWERPCB application tips 2 - powerpcb\'s own impedance calculation function powerpcb itself has a characteristic impedance calculation function, which is used as follows: 1. Define the corresponding layer that needs to be defined as the ground or power layer as CAM PLANE in setup/layer definition. 2. Enter your stacked structure in layer thinkness, such as the thickness of each layer, the dielectric constant of the board, etc. Through the above settings, select a network and press CTRL+Q, you can see the characteristic impedance, delay, length, etc. of the network. Relieve the trouble of deleting completed signal routing in powerpcb Have you encountered such a situation: due to the modification of layout and wiring, some useless signal routing needs to be deleted, but it is difficult to delete in powerpcb. It needs to be deleted one by one and one section at a time. Sometimes there are one or two signal bumps left and it takes a long time to delete them. If you encounter such a situation, don\'t worry, I will teach you a trick: the above problem is caused by the poor data structure of powerpcb. This situation will not occur in blazerouter, so you can delete the line quickly in blazerouter. Step 1: Open blazerouter Step 2: Select a bunch of signal lines you want to delete Step 3: Right-click and select the unroute command. Done, I wish you a happy line deletion. Talk about how to reduce the number of layers of multilayer boards in powerpcb The method of reducing the number of layers of multilayer boards in powerpcb is as follows. Here is an example: 4...
