电荷放电(Electrostatic Discharge,简称ESD)CDM是指静电放电压缩机(Charged Device Model,简称CDM)引起的电荷放电现象。当一个带电的电子器件与接地的金属物体或者其他器件接触时,可能会发生静电放电现象。CDM是一种非常严重的ESD现象,因为它可以瞬间破坏电子器件,导致设备损坏或失效。为了防止CDM现象的发生,需要采取一系列的ESD保护措施,包括使用适当的静电防护材料、设计适当的电路板和使用合适的静电测试设备等。

Electrostatic Discharge Charged Device Mode
静电放电充电装置模式(Electrostatic Discharge Charged Device Mode)通常简称为CDM,是指当一个电子器件被放置在一个电场中,且其中一个电极被带有静电电荷时,会发生的一种静电放电现象。在CDM测试中,测试人员使用一个电荷器或者其他装置将电荷注入电路中,然后测量器件的响应,以确定是否存在故障或损坏。CDM测试通常用于评估集成电路的静电放电灵敏度。

When an oil droplet is stationary in an electrostatic field, there are two forces acting on it: the gravitational force and the electrostatic force. The gravitational force pulls the droplet downwards towards the ground, while the electrostatic force pushes the droplet upwards towards the top of the field. The electrostatic force is caused by the interaction between the charges on the droplet and the charges on the plates of the field.
If the field is strong enough, the electrostatic force can overcome the gravitational force and cause the droplet to levitate in mid-air. This phenomenon is known as Coulombic levitation.
