It is suggested that the signal layer should adopt the positive processing mode, and the power layer and ground layer should adopt the negative processing mode, which can greatly reduce the size of the file data and improve the design speed.
the new 3D Workbench solution Bridges the gap between mechanical and electrical areas, enabling product development teams to quickly and accurately analyze signals across multiple boards.
How to consider the welding process in PCB design? 1. Power line and ground wire should meet the following requirements in PCB design: (1) The power line and ground wire of large area should be drawn into a cross section line; (2) The distribution of copp
The following introduces common circuit board analysis methods: 1, AC equivalent circuit analysis method, 2, frequency characteristics analysis method, 3, DC equivalent circuit analysis method, 4, time constant analysis
Special care should be taken to choose the form and position of segmentation, that is, to make the two better isolation, and do not hinder the flow of driving current and circuit current, with inductance or magnetic bead connection is able to isolate the
In modern high speed digital circuit design, the influence of hole on PCB signal integrity cannot be ignored. In the multilayer plate, the hole can play a good connection role, its parasitic capacitance and inductance can be ignored.
The crystal vibration does not vibrate during product debugging, which may be due to the crystal vibration device itself or PCB design.
Factors affecting PCB welding quality from PCB design to the completion of all components welding into a high quality circuit board, PCB design engineers and even the level of welding process, welding workers and many other links need to have strict contr

Layout is divided into two ways, one is interactive layout, the other is automatic layout, is generally adjusted on the basis of automatic layout with interactive layout, in the layout can be redistributed according to the situation of the line, the two g
Large PCB manufacturers use electroplating and etching processes to produce wiring on the board. For electroplating, the production process begins with the plating of copper over the outer plate substrate.PCB manufacturers
What is causing concern is the unpredictability of the noise itself. Typically, the noise may come from an external source or an internal source. Even the source of the noise poses more problems.
