Milling with ESD Spindles - 什么是ESD What ist ESD? 静电放电Electrostatic discharge (ESD) 两种材料的摩擦和静电感应可能产生电位差 The friction between two materials and electrostatic induction can create a difference of electrical potential 电位差会导致瞬间静电放电 The potential difference can lead to an ESD event ESD甚至可能产生电火花 ESD can even create spectacular electric sparks 在PCB生产中ESD可以足够损坏敏感的电子元器件 In PCB Production ESD can be large enough to cause damage to sensitive electronic components
