When making PCB circuit boards, we will import these self-made packages.
Packages drawn independently by ourselves must be completed before PCB design. In addition, we can manually modify the network table to define pads that are not on the schematic diagram such as fixed pins of some components to the network connected to it, and those without any physical connection can be defined to ground or protective ground.Ģ Draw the package library of non-standard devices defined by yourself When we are designing the PCB board, some of these 16 steps are not necessary, but these steps are common in the production of engineering PCB boards, so we will introduce them in detail below.ġ Get the correct schematic and network tableĭrawing the schematic diagram is the prerequisite for drawing the PCB board diagram, and the network table is an intermediary connecting the schematic diagram and the PCB board diagram, so you must first get the correct schematic diagram and network table before drawing the PCB circuit board.
The whole production process is divided into 16 steps. The following introduces the process of Protel DXP drawing PCB board.
