Kunetseka kuti nei Copper foil iri yakanakisa kudzivirira zvinhu?

Electromagnetic uye radio-frequency interference (EMI/RFI) inyaya hombe yeakavharidzirwa tambo magungano anoshandiswa mukufambisira data. Iko kukanganisa kudiki kunogona kukonzera kutadza kwemudziyo, kudzikiswa kwemhando yechiratidzo, kurasikirwa nedata, kana kukanganisa kuzere kwekutapurirana. Shielding, inova dhizaini yekudzivirira ine simba remagetsi uye yakaputirwa netambo yemagetsi kuti irege kuburitsa kana kusveta EMI/RFI, chikamu cheakavharidzirwa tambo maassemblies. Nzira dzinonyanya kushandiswa dzekudzivirira, "foil shielding" uye "braided shielding."

Tambo yakadzivirirwa inoshandisa yakatetepa yemhangura kana aluminium backing kuti iwedzere hupenyu hurefu inozivikanwa sefoil shielding. Waya yakadhindwa yemhangura nefoil shield zvinoshanda pamwechete kutsika nhovo.

Zvakanakira kushandisa mhangura sefoiri uye yakarukwa shielding

Mhando mbiri dzinonyanya kufarirwa dzetambo dzakavharidzirwa dzinoshandiswa mumaindasitiri ndeye foil uye dzakarukwa. Mhando mbiri idzi dziri kushandisa mhangura. Foil shielding inopa dziviriro yakakwana uye inoshingirira kune yakakwirira-frequency RFI application. Foil shield inokurumidza, yakachipa, uye iri nyore kugadzira nekuti haina huremu uye inotengeka.

Mesh uye flat braid nhovo zvese zviripo. Panguva yekugadzira, flat braid yakagadzirwa netinned copper inokungurutswa kuita braid. Iyo yakakwirira dhigirii yekuchinjika inoita kuti ive yakanakisa inodzivirira braid yemahosi nemachubhu. Inogona kushandiswa sechisungo chekubatanidza chemidziyo mumotokari, ndege, uye zvikepe pamwe chete netambo dzekudzivirira, tambo dzepasi, bhatiri pasi, uye bhatiri pasi. Inokodzera chero application inodaidza yakarukwa, tinned copper braid uye zvakare inobvisa kupindira kwekupisa. Inenge 95% yenhoo yakafukidzwa nemhangura yakagadzirwa. Nhoo dzemhangura dzakarukwa dzinogutsa zvinodiwa neASTM B-33 uye QQ-W-343 mhando S.

Copper foil matepi 'conductive adhesive yakanakira kushandura akadhindwa edunhu mabhodhi, kugadzirisa kuchengetedza alarm maseketi, uye kuisa kunze uye kugadzira wiring board prototypes. Yakanakira EMI/RFI yekudzivirira tambo yekuputira uye nekuona kuenderera kwemagetsi nekujoinha EMI/RFI makamuri akadzivirirwa. Pamusoro pezvo, inoshandiswa kuita kubata kwepamusoro nezvinhu zvisingaite sepurasitiki kana aluminium uye kudhiza magetsi akamira. Yayo yakanyungudutswa, yemhangura-inopenya hue inoita kuti ive yakakwana kune zvehunyanzvi uye mapurojekiti ehunyanzvi sezvo isingazoshatise. Pepa rakatetepa remhangura kana aluminium rinoshandiswa mukuvhara foil. Kazhinji, iyi "foil" inosungirirwa kune inotakura polyester kuwedzera simba retambo. Rudzi urwu rwetambo yakadzivirirwa, inonziwo "tepi" kudzivirira, inodzivirira zvachose waya yekondukita iyo yakaputirwa. Hapana EMI kubva kunharaunda inogona kupinda. Nekudaro, tambo idzi dzakanyanya kunetsa kubata nadzo, kunyanya kana uchishandisa chinongedzo, nekuti foil mukati metambo yakatetepa. Panzvimbo yekuedza kudzika tambo nhovo zvachose, waya yekudonha inowanzo shandiswa.

Tinted copper shield inokurudzirwa kuti ivhare nhovo huru. Kufukidzwa kwayo kwe95 muzana kunopihwa nekuumbwa kwayo kwemhangura yakarukwa. Inochinjika zvakasarudzika uye ine ukobvu hwezita hwe.020″, zvichiita kuti ive yakakwana kuti ishandiswe setambo yekubatanidza midziyo yemugungwa, mota, uye ndege.

Waya dzemhangura dzinorukwa kuita mesh yetambo dzakarukwa dzakavharirwa. Kunyange zvazvo isingadziviriri kudarika nhovo dzefoiri, nhovo dzakarukwa dzakasimba zvakanyanya. Paunenge uchishandisa chinongedzo, iyo braid iri nyore zvakanyanya kumisa uye inogadzira yakaderera-inopikisa nzira yekudzika. Zvichienderana nekuti chirukwa chakasimba sei, yakarukwa nhovo inowanzopa 70 kusvika 95 muzana EMI dziviriro. Nekuti mhangura inobata magetsi nekukasira kupfuura aruminiyamu uye nekuti nhovo dzakarukwa hadzina mukana wekuchengetedza kukuvara kwemukati, dzinoshanda kupfuura mafoil nhovo. Nekuda kwekuita kwavo kwepamusoro uye kusimba, tambo dzenhovo dzakarukwa dzinorema uye dzinodhura kupfuura nhovo dzematepi.

Kambani yedu,Civen Metal, yakaunganidza michina yekugadzira yakanakisa uye mitsetse yekusangana munyika, pamwe nehunyanzvi uye tekinoroji vashandi uye yekutanga-reti manejimendi timu. Isu tinotevera pasi rese maitiro uye zviyero zvekusarudza zvinhu, kugadzira, kutonga kwemhando, kurongedza, uye chekufambisa. Pamusoro pezvo, isu tinokwanisa kuita yakazvimirira tsvakiridzo nekusimudzira uye kugadzira yakasarudzika simbi zvinhu zvevatengi.

Unogona kushanyira webhusaiti yedu (yakanyorwa pazasi), kuti uwane rumwe ruzivo rwakadzama maererano nefoil tepi, uye tinned copper shielding, kana unogona kutifonera kuti tibatsirwe.
