PCB layout and surface treatment process PCB Chinese name is printed circuit board, also known as printed circuit board, printed circuit board, is an important electronic component, is the support of electronic components, is the provider of electrical connections of electronic components. Because it is made by electronic printing, [...]

As an important electronic connector, PCB is used in almost all electronic products and is considered to be the "mother of electronic system products". Its technological changes and market trends have become the focus of many industry players. At present, the marking processing of PCB mainly has two kinds [...]

UV laser application in various PCB materials Ultraviolet lasers are the best choice for a variety of PCB materials in many industrial applications, from the most basic circuit boards, circuit wiring, to advanced processes such as pocket-sized embedded chips. The variability of this material makes UV lasers the best [...]

First, the basic conceptual understanding of digital-analog hybrid design Many products include digital-analog mixed PCB designs with different signals with different immunity to interference. In the interconnection design process, the crosstalk between different signals must be properly controlled to ensure the requirements of the final product. It is very [...]

The definition of impedance PCB board  First, the printed circuit board impedance characteristics: According to the theory of signal transmission, the signal is a function of time and distance variables, so each part of the signal may change on the line. Therefore, the AC impedance of the connection, that [...]

For electronic products, printed circuit board design is a design process that must be passed from an electrical schematic to a specific product. The rationality of its design is closely related to product production and product quality.   For many people who are just engaged in the electronic design, [...]

PCB etching process and process control The process of printing a printed circuit board from the light board to the display of the line pattern is a relatively complicated process of physical and chemical reactions. This article analyzes the final step, etching. Currently, typical processes for printed circuit board [...]

Conducting printed circuit board (PCB) design refers to the production of circuit boards at the lowest possible cost by designing schematic drawings and wiring layout. In the past, this usually required expensive tools, but now, with the increasing popularity of free high-performance software tools and design models, the speed [...]

Double-layer PCB board manufacturing process The circuit board is the carrier of electronic design. It is the place where all electronic components and circuits are summarized. Nowadays, there are more and more electronic products, more and more components, more and more complicated circuit design, and the most basic single. [...]

We generally have a common sense when drawing PCBs, that is, thick wires (such as 50 mils or even above) where large currents are used, and thin wires (such as 10 mils) for small current signals. For some electromechanical control systems, sometimes the instantaneous current flowing through the line [...]
