On 13-14 December 1988. ERA Technology Ltd. organized a technical seminar. entitled ‘Electrostatic Problems in Industry’. in collaboration with four European consulting agencies (France. Italy. Spain and West Germany). This publication contains the fifteen papers presented at the seminar. The papers are divided into four sections: electrostatics; electronic\ - industrial problems and solutions: electrostatic protection and electrostatic problems methods: and solutiona in industry. The first paper in section I discusses the fundamentals of electrostatics. covering charge generation and retention. charge accumulation and discharges, discharge damage and electrostatic problems. and protection measurcs. The second paper reviews measurement techniques in a cursory manner, while the last paper surveys existing national and international stan-

dards. The author reports on the work performed by the Working Group 2 of the IEC/TCIS Committee. Section 2 comprises three papers on: the main origins of static electricity in electronic industries. and prevention means: possible actions in design and production against negative effects of electrostatics: and assessment of static prevention procedures in industry. The first two papers in section 3 are concerned with protection methods for electronic/communication equipment. The,y discuss electrostatic discharge tcstlng of integrated circuits and review resources. procedures. and practices for handling electrostatic sensitive devices and equipment. The last paper describes the experience of Lahoratoire Central des Industries Electriques in France in controlling electrostatic problem% with humans in the electronics industry.
