ESD susceptibility of PCB (PWB)

Does ESD effect components on PCBs (PWBs)? If so, what is the sensitivity of the PCB?

The first part is easy - yes, ESD sensitive components on a PWB can be damaged by ESD.

The second part is not easy. The answer can depend on the ESD sensitivity of the devices on the board, and the board design. The components on the board may be less susceptible or even more susceptible to ESD damage, and it is impossible to predict. Many experts say we should consider the ESD susceptibility of the board is the same as the most sensitive component on the board.
