How to consider impedance matching when designing high-speed PCB design schematics?

When designing high-speed PCB circuits, impedance matching is one of the design elements. The impedance value has an absolute relationship with the wiring method, such as walking on the surface layer (microstrip) or inner layer (stripline/double stripline), distance from the reference layer (powe...

Do you know the difference between different materials of PCB board?

  –From pcb world, The combustibility of materials, also known as flame retardancy, self-extinguishing, flame resistance, flame resistance, fire resistance, flammability and other combustibility, is to evaluate the ability of the material to resist combustion. The flammable material sa... Read More

PCB process classification

According to the number of PCB layers, it is divided into single-sided, double-sided, and multi-layer boards. The three board processes are not the same. There is no inner layer process for single-sided and double-sided panels, basically cutting-drilling-follow-up process. Multilayer boards will ... Read More
