Many people say that pcb design is an art. This sentence is not wrong, but it is not a purely artistic appreciation but a practical art combined with electronic science. Electrical performance is always the most important pursuit of PCB design, and it is the primary goal. Do not give up electrical performance in order to pursue orderliness and beauty. But then again, PCBs that achieve the best electrical performance are generally pretty beautiful.
In the design of the PCB, the anti-ESD design of the PCB can be achieved through layering, proper layout and installation. In the design process, most of the design modifications can be limited to increasing or decreasing components through prediction. By adjusting the PCB layout, ESD can be well guarded.
Right-angle alignment is generally required in pcb cabling to avoid the situation, but also almost one of the standards to measure the quality of the cabling, then the right angle of the trace will have much impact on the signal transmission? In principle, a right-angled trace will cause the linewidth of the transmission line to change, resulting in an impedance discontinuity. In fact, not only the right-angle traces, but also the angles of sharp angles and acute angles may cause impedance changes.
During the assessment, designers must ask themselves: What scale is crucial to them? Force them to review their existing development tool capabilities and begin ordering some new features.
This article will address the challenges faced by PCB design and what to consider as a PCB designer in evaluating a PCB design tool.
