ESD — The Scourge of Electronics

Sten Hellström

en Limba Engleză Paperback – 23 aug 2014

This book on electrostatic discharge phenomena is essentially a translation and update ofa Swedish edition from 1992. The book is intended for people working with electronic circuits and equipments, in application and development. All personnel should be aware of the ESD-hazards, especially those responsible for quality. ESD-prevention is a part of TQM (Total Quality Management). The book is also usable for courses on the subject. Background It was soon realised that the MOS-circuits (MOS=Metal Oxide Semiconductor), which appeared in the beginning of the 1960-ties were sensitive to electrostatic discharges. But a severe accident accelerated the search for materials that do not generate electric charges. In April 1964 three people were working inside a satellite at Cape Kennedy Space Center. They suddenly screamed "we are burning". They died. The satellite incapsulation was covered with untreated plastics to protect against dust. When the plastics was pulled off both this and the metal incapsulating got charged. A discharge from the metal ignited inflammable parts of the satellite. Eleven more people were injured and the cost of the accident amounted to about 55 billions USD.

This book deals with the influence of electrostatic discharges upon electronic components and systems and how to avoid it. The nature and the generation of static electricity is described with historical notes. The interaction between ESD and electronics is penetrated. Simulation models are given and ESD-failures including so called latent failures accounted for. Other forms of perturbation as EMI, EMC and noise are outlined. The influence on the human organism by electrostatic and electromagnetic fields has also been paid attention. Thest models and ESD protection methods are important parts of the book. Reference is made to existing international norms on ESD, EMC etc. Estimates on cost and cost saving by protection are quoted. (Disbursement and gain.) The book is applicable for anyone engaged with modern electronics as designers, protection and service technicians as well as users of electronic systems. Educational purposes can also be suggested.
