Ngaba uyazibuza ukuba kutheni i-Copper foil iyeyona nto ilungileyo yokukhusela?

Ukuphazamiseka kwe-electromagnetic kunye ne-radio-frequency (EMI/RFI) yingxaki enkulu kwiindibano zekhebula ezikhuselweyo ezisetyenziswa ekudlulisweni kwedatha. Ukuphazamiseka okuncinci kunokubangela ukungasebenzi kwesixhobo, ukwehla komgangatho wesignali, ukulahleka kwedatha, okanye ukuphazamiseka ngokupheleleyo kokudluliselwa. Ukukhusela, okumaleko wokukhusela oqulethe amandla ombane kwaye kujikelezwe kwintambo yombane ukuyithintela ekukhupheni okanye ekufunxeni i-EMI/RFI, yinxalenye yeendibano zekhebula ezikhuselweyo. Iindlela zokukhusela ezisetyenziswa kakhulu, "kukukhusela ngefoyile" kunye "nokukhusela okuqhiniweyo."

Intambo ekhuselweyo esebenzisa uqweqwe oluncinci lwethusi okanye i-aluminium backpack ukwandisa ubomi bayo yaziwa ngokuba yi-foil shielding. Intambo yokukhupha ubhedu efakwe kwi-tin kunye ne-foil shield zisebenza kunye ukuze zisike ikhaka phantsi.

Iingenelo zokusebenzisa ubhedu njenge-foil kunye ne-braid shield

Iintlobo ezimbini ezidumileyo zeentambo ezikhuselweyo ezisetyenziswa kwimizi-mveliso yifoyile kunye ne-braised. Zombini ezi ntlobo zisebenzisa ubhedu. Ukukhusela ifoyile kunika ukhuseleko olupheleleyo kwaye kuyamelana nezicelo ze-RFI ezisetyenziswa rhoqo. Ukukhusela ifoyile kukhawuleza, kungabizi, kwaye kulula ukuyifaka kuba ilula kwaye ifikeleleka.

Izikhuselo ze-Mesh kunye ne-flat braid zombini ziyafumaneka. Ngexesha lokwenziwa, i-flat braid eyenziwe ngobhedu olufakwe kwi-tin ifakwa kwi-braid. Ukuguquguquka kwayo okuphezulu kwenza ukuba ibe yi-braid ekhuselayo kakhulu kwiipayipi kunye neetyhubhu. Ingasetyenziswa njenge-bonding strap kwizixhobo zeemoto, iinqwelomoya, kunye neenqanawa kunye neentambo zokukhusela, imitya yomhlaba, i-grounding battery, kunye ne-grounding battery. Ifanelekile kuyo nayiphi na into edinga i-luken, i-tin copper braid kwaye ikwasusa ukuphazamiseka kokutsha. Ubuncinane be-95% yekhaka ligqunywe yi-tin copper. Izikhuselo ze-copper ezifakwe kwi-tin ziyahlangabezana neemfuno ze-ASTM B-33 kunye ne-QQ-W-343 type S.

Iiteyiphu zefoyile yobheduI-conductive adhesive ifanelekile ekutshintsheni iibhodi zesekethe eziprintiweyo, ukulungisa iisekethe ze-alamu zokhuseleko, kunye nokubeka nokuyila iiprototypes zebhodi yentambo. Ilungele ukusonga intambo ye-EMI/RFI kunye nokuqinisekisa ukuqhubeka kombane ngokudibanisa amagumbi akhuselweyo e-EMI/RFI. Ukongeza, isetyenziselwa ukwenza unxibelelwano lomphezulu nezinto ezinganyibilikiyo ezifana neplastiki okanye i-aluminium kunye nokukhupha umbane ongashukumiyo. Umbala wayo otyhidiweyo, okhanyayo njengobhedu wenza ukuba ifaneleke kwiiprojekthi zobugcisa kunye nemisebenzi yezandla kuba ayizukubola. Ishiti elincinci lobhedu okanye i-aluminium lisetyenziswa ekukhuseleni i-foil. Ngokwesiqhelo, le "foil" incamathiselwa kwi-polyester carrier ukwandisa amandla entambo. Olu hlobo lwentambo ekhuselweyo, ekwabizwa ngokuba yi-"tape" shielding, ikhusela ngokupheleleyo intambo ye-conductor ejikelezileyo. Akukho EMI kwindalo esingqongileyo enokungena kuyo. Nangona kunjalo, ezi ntambo zinzima kakhulu ukuzisingatha, ngakumbi xa usebenzisa isixhumi, kuba i-foil engaphakathi kwintambo ibuthathaka kakhulu. Endaweni yokuzama ukumisa ngokupheleleyo i-cable shield, i-drain wire iya kusetyenziswa.

Ikhaka lekopolo elinombala liyacetyiswa ukuze ligqume ikhaka elikhulu. Ikhaka layo eliphantsi elingama-95 ekhulwini libonelelwa yimveliso yalo yobhedu olulukiweyo nolufakwe kwikotoni. Liguquguquka kakhulu kwaye linobukhulu obuqhelekileyo obuyi-.020″, nto leyo eyenza ukuba lifaneleke ukusetyenziswa njengentambo yokubopha izixhobo zaselwandle, iimoto kunye neenqwelomoya.

Iingcingo zobhedu zilukwa zibe yimesh kwiintambo ezigqunyiweyo ezilukiweyo. Nangona zingakhuseli kangako kunezikhuselo zefoyile, izikhuselo ezilukiweyo ziqinile kakhulu. Xa usebenzisa isixhumi, i-braid kulula kakhulu ukuyiphelisa kwaye idala indlela yokumelana okuncinci ukuya ekumisweni komhlaba. Ngokuxhomekeke ekubeni i-braid ilukiwe kangakanani, i-braid shielding idla ngokubonelela ngokhuseleko lwe-EMI lwama-70 ukuya kuma-95 ekhulwini. Ngenxa yokuba i-copper iqhuba umbane ngokukhawuleza kune-aluminium kwaye ngenxa yokuba izikhuselo ezilukiweyo azinakwenzeka ukuba zonakale ngaphakathi, zisebenza ngakumbi kunezikhuselo zefoyile. Ngenxa yokusebenza kwazo okuphezulu kunye nokuqina, iintambo zezikhuselo ezilukiweyo zinzima kwaye zibiza kakhulu kunezikhuselo zeteyiphu.
