In short, ESD is the rapid neutralization of charge. We know

of electrons and protons. When the material gains or loses electron, it will lose its balance and become

negatively or positively charged. Positive or negative charge accumulation on the surface will make
static electricity on object, usually causing damage to the electronic components.
