INTRODUCTION TO ESD HOW STATIC CHARGE IS GENERATED Triboelectrification : Any material, whether a conductor or non-conductor, can be charged triboelectrically. The magnitude and polarity of the charge depends on the characteristics of the two materials. They are affected by several factors, such as the surface condition, size of the contact area, speed of separation or rubbing etc,. Induction : Static Charge present on an object creates an electrostatic field. When a conductive object is placed within the electrostatic field and connected to the ground, it takes on a static charge of opposite...

PROBLEMS CAUSED BY STATIC CHARGES Contamination : Materials used in the cleanroom are typically good insulators and become charged easily. If a critical product’s surface becomes charged, the surface will attract airborne particulates in the cleanroom. Once these particles are bonded to a charged surface, it will be very difficult to remove these particles. Contamination of this nature is a major contributor to product degradation and device failure. Destruction Of Sensitive Devices : ESD can cause electronic device failure during any phase in the production, packaging and testing processes....
