Printed Circuit Board component library Reverse Engineering need to prepare component list and netlist, functional blocks and other important elements;
The preliminary preparation includes preparing component libraries and schematic diagrams In order to manufacturing a well-functional PCB board, in addition to designing the printed circuit board principles, it is also necessary to redraw electronic pcb board well. Before proceeding with PCB design,
Printed Circuit Board component library Reverse Engineering need to prepare component list and netlist, functional blocks and other important elements;
we must first reverse engineering OLD circuit board component library. element You can use protel’s own library for the library building, but it is generally difficult to find a suitable library. It is best to make your own component library based on the standard size data of the selected device.
In principle, compiling the PCB component library first and then the SCH component library. PCB component library requirements are high which will directly affects the installation of the PCB board; SCH component library requirements are relatively loose, as long as you pay attention to well-defined management Pin attributes and the corresponding relationship with PCB components will do.
PS: Pay attention to the hidden pins in the standard library. After that is the design of the schematic, do
