Abstract
The article considers a mathematical model for determination of transition resistance in electrical contacts. The suggested model considers elastic, elastoplastic and plastic deformations of micro-protrusions on rough contact surfaces, the presence of surface films and dust particles on them. A theoretical dependence of possible contact failure on dust content has been obtained.
Highlights
One of the methods to increase electronics reliability is prevention of operation faults and failures
Failures are frequently caused by faulty electrical contacts
Fault and failure conditions in such contacts are basically caused by dust and other contaminants in the intercontact space, formation of films, which remain in place at contact closing
Summary
One of the methods to increase electronics reliability is prevention of operation faults and failures. Failures are frequently caused by faulty electrical contacts. Electrical contact faults are caused by thermal, electrical, mechanical and chemical phenomena taking place in the transition area. At present low-level contacts are widespread, i.е. Contacts with less than 0.1А current and 5V max voltage. Fault and failure conditions in such contacts are basically caused by dust and other contaminants in the intercontact space, formation of films, which remain in place at contact closing. Development of efficient methods for determination of failure causes in low-level electrical contacts requires creation of mathematical models that enable to determine transition area characteristics in the real operation conditions
