The reason PCBs are called single-sided is because the simplest PCBs have parts on one side and wires on the other. This is because the wires only appear on one side. Multilayer boards with multiple layers of conductors require proper circuit connections between the two layers. The bridge between the chains is called a viaduct. The basic PCB design process of FS technology can be divided into four steps:
(2) Network report generation: An online report is a report showing the circuit principle and connection relationship between different components. Bridging and connecting circuit boards and circuit board designs. With the help of the schematic network report, you can quickly find the connection between components, which is convenient for subsequent PCB design.
(3) FS Technology PCB Design: PCB design is what we usually call PCB design. This is the final converted form of the circuit diagram. The corresponding design of this part is more complicated than the schematic design. The powerful design features of Protel DXP can complement this part of the design.
(4) Generate FS Technology PCB report: After the PCB design is completed, it is necessary to generate various reports such as output report, PCB information report, network status report, etc., and finally print the PCB layout.
1. PCB classification of FS Technology
PCBs are divided into three categories: single-sided, double-sided and multi-layer printed circuit boards according to the number of layers.
1. Single-sided, the simplest PCB, the parts are concentrated on one side and the wires are concentrated on the other side. This type of PCB is called single-sided because the wires only appear on one side. Single panels are generally easy to manufacture and inexpensive, but they have the disadvantage that they cannot be used for overly complex products.
2. Both sides are extensions of one side. If single-layer wiring is not what your electronics require, use both sides. There are copper pours and traces on both sides, allowing the wires between the two layers to pass through vias to form the desired net connections.
3. FS technology multilayer board is a printed circuit board in which three or more layers of conductive patterns and insulating materials are separated by lamination and connected to each other as needed. Multilayer circuit is the product of the development of electronic information technology in the direction of high speed, multi-function, large capacity, small capacity, thinner and lighter.
Printed circuit boards are divided into flexible boards (FPC), rigid boards (PCB) and rigid flexible boards (FPCB) according to their characteristics
