Tinogona kuona kudzivirira paPCBS dzakawanda, kunyanya mumagetsi evatengi akadai senharembozha. PCB yefoni yakafukidzwa nenhoo.
Zvivharo zvekuvharira zvinonyanya kuwanikwa munharembozha PCBS, kunyanya nekuti nharembozha dzine akasiyana siyana emafoni ekutaurirana maseketi, akadai seGPS, BT, WiFi, 2G/3G/4G/5G, uye mamwe masekete anocherekedza analog uye DC-DC switching power circuits anowanzoda kuiswa ega nemavhavha ekudzivirira. Kune rumwe rutivi, haaiti mamwe matunhu, uye kune rumwe rutivi, anodzivirira mamwe matunhu kuti asazvikanganisa ivo pachavo.
Iri nderimwe remabasa ekudzivirira kubva kune electromagnetic interference; Rimwe basa renhovo nderekudzivirira kudhumhana. PCB SMT ichakamurwa kuita akawanda mabhodhi. Kazhinji, mahwendefa ari padyo anofanirwa kupatsanurwa kudzivirira kudhumhana kwepedyo panguva yekuedzwa kunotevera kana kumwe kutakurwa.
Zvigadzirwa zvenhovo zvinowanzova chena mhangura, simbi isina tsvina, tinplate, etc. Parizvino, nhovo dzakawanda dzinoshandiswa mumhangura chena.
Mhangura chena inoratidzirwa neasina hurombo kudzivirirwa mhedzisiro, yakapfava, inodhura kupfuura simbi isina tsvina, nyore kuita tin; Stainless simbi inodzivirira mhedzisiro yakanaka, yakasimba simba, ine mwero mutengo; Zvisinei, zvakaoma kuisa tin (haigoni kuva tin pasina kugadziriswa kwepamusoro, uye inovandudzwa mushure mekugadzira nickel, asi haisati yagadzirisa chigamba); Iyo tinplate shielding effect ndiyo yakaipisisa, asi tin yakanaka uye mutengo wakachipa.
Iyo nhoo inogona kukamurwa kuita yakagadziriswa uye inobviswa.
Single-piece Shielding cover yakagadziriswa inowanzonzi imwe-chidimbu, yakananga SMT yakanamatira kuPCB, Chirungu chinowanzonzi Shielding Frame.
Iyo inobviswa-maviri-nhoo nhovo inowanzonziwo maviri-chidimbu nhovo, uye maviri-chidimbu nhovo inogona kuvhurwa zvakananga pasina rubatsiro rwechidzitiro chepfuti. Mutengo wacho unodhura kupfuura chidimbu chimwe chete, iyo SMT yakasungirirwa paPCB, inonzi Shielding Frame, iri pamusoro inonzi Shielding Cover, yakananga paShielding Frame, iri nyore kupatsanura, kazhinji iyo inotevera Frame inonzi shielding frame, iyo Kavha iri pamusoro inonzi shielding cover. Frame inokurudzirwa kushandisa chena mhangura, tini iri nani; Kavha inogona kugadzirwa netinplate, kunyanya yakachipa. Zvimedu zviviri zvinogona kushandiswa padanho rekutanga repurojekiti kufambisa debugging, kumirira kugadzikana kwehardware debugging, uyezve funga kushandiswa kwechidimbu-chidimbu kuderedza mutengo.
