What is Electromagnetic Wave

What is Electromagnetic Wave??? In electronics theory, when current flows through a conductor, a magnetic field is formed around the conductor; when an alternating current passes through the conductor, an alternating electromagnetic field is formed around the conductor, which is called electromagnetic wave. When the electromagnetic wave frequency is lower than 100khz, the electromagnetic wave…

Clone Electronic PCB Card Layout Design

Clone Electronic PCB Card Layout Design needs to pay attention to below points, which will ensure the electrical integrity and functionality compatibility in the reverse engineering printed circuit board schematic: Several basic principles: any wire in the electronic pcb card layout design has impedance; current always automatically selects the path with the least impedance; radiation…

Multilayer Printed Circuit Board Schematic Reverse Design

Under normal circumstances, Multilayer Printed Circuit Board Schematic Reverse Design is carried out according to circuit functions. When re-wiring on the PCB board’s outer layer, more circuitry wiring pattern is required on the soldering surface and less wiring on the component surface, which is more convenience to the maintenance and troubleshooting of the printed circuit…
