Abstract

En formet-på-plass elektrisk ledende tetning kan anvendes som EMI-skjermingstelning og også anordnes mellom koblede husdeler i elektronisk utstyr. Tetningen består av el flytende polymermateriale omfattende elektrisk ledende partikler deri. En fremgangsmåte og et apparat for å tilveiebringe tetningen omfatter å ekstrudere det elektrisk ledende partikkelfylt polymermateriale fra et system omfattende flere beholdere (A, B, C) for å romme flere forhåndsblandede bestanddeler og et blandingskammer (78). Flytende polymermateriale males fra beholderne (A, B, C) lil et kammer (141) i ekslruderen. Trykk påføres det flytende polymermateriale ved et trykktilførselssystem som omfatter en kilde av positivt trykk (121) og av negativt trykk (125) og en kontrollmodul (126) for selektivt å tilfore positivt og negativt trykk til ekstruderingskammeret (121) for å danne en felg av elektrisk ledende, flytende polymermaterialet på et substrat (115) som deretter herdes for danne en EMI-tetning.
