Before leaving the manufacturer, the bare PCB (printed circuit board) and PCB assembly (PCBA) must pass the electrical test to ensure that the circuit board has high performance and high reliability in the final product. Conduct electrical tests to find electrical and circuit problems, such as short circuits, open circuits, resistance, capacitance, etc. All these …
With the continuous expansion of the market demand for portable electronic products, electronic devices are becoming more and more light, thin, short, small and multifunctional. In particular, the application of flexible board for high-density interconnect structure (HDI) will greatly promote the rapid development of flexible printed circuit technology. At the same time, with the development …
Aluminum PCB (metal base heat dissipation plate (including aluminum substrate, copper substrate and iron substrate)) is a low alloyed Al Mg Si high plastic alloy plate. It has good thermal conductivity, electrical insulation and machining performance. Compared with traditional FR-4, aluminum pcb adopts the same thickness and line width, it can carry higher current, and …
For PCB designers, creating a schematic symbol library and PCB packaging library is a very basic but very important work. Only by ensuring the accuracy of the schematic symbol library and PCB packaging library can we ensure the smooth development of PCB design. This book systematically introduces the methods and skills of schematic symbols and …
The biggest difference between flexible electronic printing and printed circuit board is that the current carrying capacity of wires is different. The heat dissipation capacity of flexible electronic printing is relatively poor, so the current carrying capacity it can bear is relatively small; The heat dissipation capacity of printed circuit board is relatively strong, and …

Regarding the design of the PCB circuit board, do you know what the design process is there? 1. Preliminary Preparation Preliminary preparation includes preparing component libraries and schematic diagrams. Before proceeding with PCB design, we must first prepare the schematic SCH component library and PCB component packaging library. PCB component package library is best established …
What’s a Circuit Diagram? A circuit diagram refers to a diagram showing circuit connections with circuit element symbols. Circuit diagram is a kind of principle layout diagram which is drawn with standardized symbols of physical electricity to represent the composition and relationship of components for the needs of research and engineering planning. The working principle …

There are mainly 4 classifications of circuit diagram, they are schematic, block diagram, assembly drawing and printed board diagram. Follow we will introduce them. Schematic It’s also called “electrical schematic diagram”. This kind of diagram, because it directly embodies the structure and working principle of the electronic circuit, is generally used in the design and …
