I believe everyone knows the working principle of the circuit board design: the insulating material of the substrate is used to isolate the conductive layer of the copper foil on the surface, so that the current can wander in various components along the route designed in advance, thus realizing functions such as doing work, amplifying, attenuating, modulating, demodulating and coding.
In the most basic flexible printed circuit board, the parts are basically concentrated on one side and the wires are concentrated on the other side. This kind of flexible printed circuit board is called a single panel because the wires only appear on one side. Multi-layer board, with wires in multiple layers, must have proper circuit connection between two layers. The bridge between circuits is called via. The basic design process of circuit board can be divided into the following four steps:
(1) Design of circuit schematic diagram-The design of circuit schematic diagram mainly uses ProtelDXP’s schematic editor to draw the schematic diagram.
(2) Generate network report form-network report form: showing the circuit principle and the link relationship between each component in the circuit. It is the bridge and link between circuit schematic design and circuit board design. Through the network report of circuit schematic diagram, the connection between components can be found quickly, which will provide convenience for future flexible printed circuit board design.
(3) Design of printed circuit board-the design of printed circuit board is what we usually call flexible printed circuit board design, which is the final form of circuit schematic diagram transformation. This part of related design is more difficult than that of circuit schematic diagram design, and we can complete this part of design with the help of ProtelDXP’s powerful design function.
(4) Generating printed circuit board report-After the design of printed circuit board is completed, there is still the last process to be completed, that is, generating report: circuit board information report, pin report, network status report, etc., and finally printing the printed circuit diagram.
