This clause presents both the general and the validation ESD requirements for internal parts and materials.
• General ESD requirements for internal parts presented in 9.2 concern any dielectric (or isolated conductor-dielectric combination), potentially subject to electrostatic breakdown, for example:
¾ cable insulation;
¾ printed circuit boards;
¾ integrated circuit packaging;
¾ ungrounded spot shielding;
¾ optical elements.
In addition parts include any internal system sensitive to electric fields and comprising insulators or isolated conductors, for example:
¾ triaxial accelerometers;
¾ microelectromechanical systems (MEMS).
• ESD requirements for validation of internal parts and materials presented in 9.3 are provided to ensure that mitigation against hazardous levels of internal charging are put into effect.
