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...Read more -
Copper clad laminate is the core substrate
The manufacturing process of copper clad laminate (CCL) is to impregnate the reinforcing material with organic resin and dry it to form a prepreg. A blank made of several prepregs laminated together, one or both sides covered with copper foil, and a plate-shaped material formed by hot pressing. F...Read more -

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
