Printed Circuit Board Operational Principle

Printed Circuit Board Operational Principle

The operational principle of printed circuit board is by use insulation material to separate the surface copper foil electrical layer, so the current can flow alongside the tracks which has been designed in advanced and provide power for components to fulfill their functions such as provide power, amplification, attenuation, coding, decoding and code compiling, etc.

1, schematic diagram design is mainly use PROTEL DXP schematic diagram compiling editor to draw it;

2, generate net-list report—net-list report can be used to display the connection relationship net-list of electrical principle with other components, it is the bridge and bond from electrical schematic diagram to printed circuit board design/layout, through net-list of electrical schematic diagram can swiftly find the connection among components and provide more convenience to the PCB design/layout;

3, Printed circuit board design is the final form of electrical schematic diagram, the related design has more difficult than the schematic diagram compiling, by the courtesy of powerful PROTEL DXP can complete this part of design;

4, Generate printed circuit board net-list, after the printed circuit board design has been completed, need to generate various net-lists, such as the pin statement, PCB info statement, network statement, and finally comes the schematic diagram;
