Three plastic materials: Lexan, Araldit and Ultramid were considered. The conditions of high vacuum ?$(1X10^{-6} mbar)$? and the temperature of 135°C were provided by the laboratory experimental equipment where plastic materials were outgassed for 48 hours. The gas mixture obtained by the outgassing procedure was analysed with the mass spectrometer. Beside other gasses saturated and unsaturated hydrocarbons ?$C_nH_m$? with low number of carbon atoms were detected. The most intensive contamination of the relay atmosphere with hyrocarbons was found for Araldit while the other two materials have rather low outgassing rate therefore its influence on the relay at mosphere contamination is negligiblePredstavljen je vpliv vakuumskega razplinjevanja kot čistilnega postopka na izboljšanje kontaktnih lastnosti in zanesljivosti delovanja miniaturnih relejev. Sistematično smo raziskali vakuumsko razplinjevanje treh plastičnih materialov za releje: Lexan, Araldit in Ultramid. V visokem vakuumu pri tlaku v razredu ?$1X10^{-6}m mbar$? in 135°C smo v laboratorijski eksperimentalni napravi 48 ur razplinjevali plastične materiale. V plinski mešanici sproščenih plinov pri razplinjevanju smo z masnim spektrometrom ugotovili vrsto primesi, med drugim tudi nekatere nenasičene ogljikovodike ?$C_nH_m$? z nizkim številom ogljikovih atomov, ki jih je največ v Aralditu in povzročajo onesnaženje atmosfere v releju. Ostala dva materiala imata nizko stopnjo razplinjevanja in na onesnaženje atmosfere v relejih le malo vplivataTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaStrokovno društvo za mikroelektroniko, elektronske sestavne dele in materiale
