EMI Isoko rya Gasike Inzira: Imyitozo Yumwitozo Uhereye kubutaka

Urabaza ibijyanye na EMI isoko yisoko, kandi buriwese asimbukira kuri 5G nibinyabiziga byamashanyarazi. Ibyo ntabwo ari bibi, ariko ni igisubizo cyo hejuru. Ihinduka nyaryo riri mubumenyi bwibintu nubugome, akenshi birengagizwa, ubwubatsi bwubwubatsi dukora burimunsi. Ntabwo ari ukurinda gusa gukora neza; bijyanye nigiciro-kuri-imikorere kwisi aho urukuta ruzengurutse rugenda rworoha kandi urusaku rugenzura rukomera. Nabonye ibishushanyo byinshi binanirana kuko bagereranya gasketi ishingiye kuri datasheet yonyine, batumva uko yitwara mugihe cyo kwikuramo, igihe, cyangwa mumurongo wukuri wisi.

Imbyino yibikoresho: Kurenga Elastomers Yayobora

Imyaka myinshi, silicone yuzuye ifeza yari umwami. Yizewe, iteganijwe, ariko ihenze kandi hamwe na compression yashyizeho ibibazo bikurikirana igihe kirekire. Ikigezweho ubu ni ugucamo ibice. Turimo kubona ubwiyongere bukenewe umwenda w'icyuma hejuru ya furo gasketi, cyane cyane muri elegitoroniki y'abaguzi no mu kabari k'itumanaho. Zitanga gukingira gukomeye, imbaraga zo gufunga hasi, kandi byoroshye gukora munteko. Ariko gufata? Kuramba kurwanya inzitizi zumuryango no gufunga ibidukikije birashobora kuba intege nke. Nubucuruzi.

Noneho harazamuka plastike ikora hamwe nuburyo bukoreshwa (FIP). FIP irashimishije - isezeranya geometrie itunganijwe neza kandi nta gikoresho cyerekana imiterere yihariye. Ariko mubikorwa, gukiza igihe nikibazo cyo kubyara umusaruro, kandi kunanirwa gufatira hejuru yifu yifu ni umutwe usanzwe. Ndibuka umushinga wigikoresho cyo gufata amashusho yubuvuzi aho umurongo wa FIP wagize igipimo cya 2% cyo gutsindwa gusa kuri adhesion. Twabuze ibyumweru byo gukemura ibibazo mbere yo guhinduranya kubanza gukata elastomer kwiyambura hamwe n'umuvuduko ukabije. Isomo: icyerekezo ntabwo buri gihe ari igisubizo kiboneye.

Ndetse no mubikoresho gakondo, formulaire iratera imbere. Silicone yo hasi yuzuye yuzuye nikel-grafite cyangwa aluminiyumu igenda yiyongera kubisabwa aho uburemere nigiciro ari ingenzi, nubwo utamba ingabo zimwe kuri radiyo ndende. Nibikorwa bihoraho kuringaniza imikorere yumuriro, ibikoresho bya mashini, hamwe na fagitire yibikoresho.
