What principles should be followed in PCB layout design

PCB circuit board is the support of circuit components and devices in electronic products. Even if the circuit schematic design is correct, the printed circuit board is not properly designed, which will adversely affect the reliability of electronic products. When designing printed circuit board, we should adopt correct method, abide by the general principle of [...]

The difference between PCB and PCBA

PCB refers to the circuit board, and PCBA refers to the circuit board plug-in assembly, added SMT and DIP process. PCB is a bare board, and PCBA is a finished board. A printed circuit board (PCB) is called a "printed circuit board." It is made of a glass epoxy resin material. According to the [...]

How to improve the thermal reliability of PCB

In general, the copper foil distribution on PCB board is very complicated, and it is difficult to model accurately. Therefore, it is necessary to simplify the shape of wiring and make the electronic components on the board of ANSYS model, which are close to the actual circuit board, to be simulated by simplified modeling, [...]

Global PCB industry growing faster

Prior to the advent of PCBs, the interconnections between electronic components were made by directly connecting electrical wires. To simplify wiring, people printed circuit patterns on the substrates and formed pathways through copper plating. As a result, printed circuit boards came into being. Has now developed into a cornerstone of the electronic information industry. [...]
