When designing a printed circuit board (PCB), following basic pcb layout rules is essential to ensure the functionality and performance of the circuit. The basic rules of PCB layout:1.According to the layout strategy of ‘major priority, complexity first’, i.e., the key unit circuits and core components should be arranged first.2.In the layout process, should refer
PCB side plating, also known as pcb edge plating, is a copper plating that is applied from the top to the bottom surface of the board and along (at least) one of the peripheral edges. PCB edge plating is the process of allowing a metallised layer to extend up to the edge of the board
In the production process of electronic products, circuit card assembly testing is a crucial step, which is directly related to the performance and reliability of the product. Circuit card, as a carrier connecting various electronic components, the quality of its assembly directly affects the function of the whole system to achieve. Therefore, a reasonable assembly
What is pcb coating material?PCB coating is a thin, polymer film (about 12-200 microns) applied to the populated board. It provides electrical insulation and protects the board from external components or the adverse conditions of the environment in which it is used. Harsh factors include (but are not limited to) the following: Benefits of Conformal
