How does grounding relates to ESD?
Grounding is especially important for effective ESD control. It should be clearly defined, and regularly evaluated. The equipment grounding conductor provides a path to bring ESD protective materials and personnel to the same electrical potential.
How to prevent ESD in PCB?
ESD Prevention by Design
- Use ground planes extensively, as these can help bypass ESD to ground, and prevent it from passing through the active parts of the PCB.
- Reduce line lengths to reduce parasitic inductance.
- Provide adequate spacing between traces carrying different voltages.
How does a PCB design affect ESD protection?
Nearly every element of your PCB design (traces, routing, layers, electronic component placement, and spacing) can affect the PCB ESD protection on your board.
Why is it important to know about ESD protection?
For the home hobbyist or student a good knowledge of ESD helps preventing damage to a PCB that represents many hours of labour. There are many ways in which ESD protection can be applied to electronics circuits and assemblies, as well as to the areas in which they are build, stored and tested.
What happens if an ESD reaches an IC?
The result of an ESD event directly reaching one of these electronic components is usually disastrous, completely ruining the IC. Nearly every element of your PCB design (traces, routing, layers, electronic component placement, and spacing) can affect the PCB ESD protection on your board.
How are Electronics stored in an ESD controlled area?
Store components in an ESD controlled area: It is not only necessary to ensure that electronics assemblies are built within an environment in which ESD protection is paramount. It is also necessary to ensure that all components are stored and transported within an environment in which ESD protection is implemented.
