Principles of PCB layout design
For large Components such as ICs, BGA and non-positioning connectors, 50 to 100 mil grid can be used for layout. For small compnents such as resistors, capacitors and inductors, 25 mil grids can be used for layout. Using grid points for layout can make thread more
What are the signal interferences in the PCB ?
Interference in the PCB can be divided into radiated interference and conducted interference. Radiated interference is the interference source that uses space as a medium to interfere its signal with another electrical network. Conducted interference useread more
