Suppression of Conductor Crosstalk on PCB Boards Routes are avoided when designing and cabling. As long as there are electronic components such as integrated circuits, which can be used for electrical interconnection between them, in order to suppress the crosstalk between the PCB circuit board wires, in designing the wiring to avoid the long distance of the equal alignment, so need to use pcb circuit board. In the research process of larger electronic products, the lowest level of success factors are the design, documentation, and manufacturing of printed boards. Its design and manufacturing quality directly affect the quality and cost of the entire product, and even lead to the success or failure of commercial competition.
PCB design needs to set different points in different stages. In the layout stage, large grid points can be used for device layout.
When I saw the PCB of a computer motherboard, I thought I was able to draw a great thing myself. Later when touched protel99se and entered the drawing board team, followed by Altium, Cadence, and so on. As the experience of the drawing board accumulated, more and more issues were noticed. A good PCB board is not only connected to the line.
The circuit diagram, which is a schematic diagram of the connection of the electronic components drawn by symbols of the circuit components, describes in detail the connection and direction of each component, the description of each pin, and some detection data.
To master several methods of analyzing common circuits, familiarize yourself with the circuit types and analysis steps that are appropriate for each method.
The significance, classification and composition of electronic circuit diagram
The pad design is designed to achieve the smallest diameter, which is at least 0.5 mm greater than the maximum diameter of the weld terminal orifice flange. The test pads must be provided for all nodes in accordance with ANSI/IPC 2221. Nodes are two or Electrical connection points between multiple components. A test pad requires a signal name (nodal signal name), the xy coordinate axis associated with the reference point of the printed circuit board, and the test pad's coordinate position (describe the test pad On which side of the printed circuit board). The information needed to provide fixtures for SMT will also need to be printed on the assembly technique of the circuit board assembly to "fix the device in the circuit test" or commonly referred to as "fixed nail bed." With the help of devices" to promote testability in the circuit. In order to achieve this purpose, you need to:
PCB shape and size are determined by the placement machine's PCB transmission method and mounting area.
Schematic design software, ORCAD is OK. Netlist is basically the industry standard.

Six FAQ Analysis of Cadence Design
A perfect PCB:
The transmission rate of high-speed PCB design and cabling systems is steadily accelerating, and it also brings about some kind of anti-jamming vulnerability. This is because the higher the frequency of transmitting information, the higher the sensitivity of signals, and the lower and higher the power of their signals. The wiring system at this time is more susceptible to interference. Interference is ubiquitous. Cables and equipment can interfere with other components or be severely disturbed by other sources of interference, such as: computer screens, mobile phones, motors, radio transmission equipment, data transmission, and power cables. In addition, potential eavesdroppers, cybercriminals, and hackers continue to increase because of their enormous damage and loss to UTP cable information interception.
The reuse function provides design duplication for powerpcb (ie, a system that implements a modular design). For the successful use of the reuse function, we greatly improve our work efficiency; and we can call some successful designs and high-performance modules in the new design, thus improving the success rate of our new product pcb design.
To do high-speed PCB design, you must first understand the following basic concepts. This is the basis.
