32 Examples of Failures due to Induction Charging 1) An uncharged device has no electrical polarization. 2) When a vacuum pad that has been charged due to repeated operations gets close to the device, static induction occurs. This figure shows that electrons move toward the electrode: the chip and its surroundings are positively charged. 3) When the device is mounted on a circuit board, electrostatic discharge occurs. In this case, a conductive rubber pad needs to be used. 1) An uncharged device has no electrical polarization. 2) When an operator gets close to the device, induction charging occurs. The operator side of the device is negatively charged and the other side is positively charged. 4) If the device is insulated, it becomes negatively charged when the operator leaves the device due to the remaining electrons. 5) When the device is once again grounded, electrostatic discharge occurs again. Electrons (.) flow out. 3) When the device is grounded under this condition, static electricity is discharged. Electrons (.) flow into the device from the ground.
