Pcb ground shielding
SpletThis ground is the connection of a safety wire from the AC mains to the product’s case or chassis. Because an earth ground and chassis ground serve the same function, these … SpletThis ground is the connection of a safety wire from the AC mains to the product’s case or chassis. Because an earth ground and chassis ground serve the same function, these terms are often used interchangeably along with the term safety ground. When it comes to grounding a PCB, there is no one-size-fits-all approach.
