Singabona ukuvikela kuma-PCBS amaningi, ikakhulukazi kuma-electronics abathengi afana nomakhalekhukhwini. I-PCB yefoni imbozwe izihlangu.
Amakhava okuvikela atholakala kakhulu kumakhalekhukhwini we-PCBS, ikakhulukazi ngenxa yokuthi omakhalekhukhwini banezinhlobonhlobo zamasekhethi zokuxhumana angenazintambo, njenge-GPS, BT, WiFi, 2G/3G/4G/5G, namanye amasekhethi e-analog abucayi kanye namasekhethi kagesi ashintshwayo e-DC-DC. ngokuvamile kudingeka ihlukaniswe ngekhava evikelayo. Ngakolunye uhlangothi, azithinti ezinye izifunda, futhi ngakolunye uhlangothi, zivimbela ezinye izifunda ukuthi zingazithinti.
Lona omunye wemisebenzi yokuvikela ekuphazamiseni kazibuthe kagesi; Omunye umsebenzi wehawu ukuvikela ukushayisana. I-PCB SMT izohlukaniswa ngamabhodi amaningi. Ngokuvamile, amapuleti aseduze adinga ukuhlukaniswa ukuze kuvinjelwe ukushayisana okuseduze phakathi nokuhlolwa okulandelayo noma okunye ukuthutha.
Izinto zokusetshenziswa zesihlangu ngokuvamile ziyithusi elimhlophe, insimbi engagqwali, i-tinplate, njll. Njengamanje, izihlangu eziningi zisetshenziswa ngethusi elimhlophe.
Ithusi elimhlophe libonakala ngomphumela ongemuhle wokuvikela, uthambile, ubiza kakhulu kunensimbi engagqwali, ukuthayela okulula; Umphumela wokuvikela insimbi engagqwali muhle, amandla aphezulu, intengo emaphakathi; Kodwa-ke, kunzima ukuthayela (akukwazi neze ukuthi kube ithini ngaphandle kokwelashwa okungaphezulu, futhi kuyathuthukiswa ngemuva kokufakwa kwe-nickel, kodwa namanje akusikhiphi isichibi); Umphumela wokuvikela i-tinplate mubi kakhulu, kodwa ithini lihle futhi intengo ishibhile.
Isihlangu singahlukaniswa sibe fixed futhi detachable.
Ikhava ye-Single-piece Shielding elungisiwe ngokuvamile ibizwa ngokuthi i-single-piece, i-SMT ngqo enamathiselwe ku-PCB, isiNgisi ngokuvamile esibizwa ngokuthi Uhlaka Lwe-Shielding.
Isihlangu esihlukanisekayo esinezicucu ezimbili sivame ukubizwa ngokuthi isihlangu sezingxenye ezimbili, futhi isihlangu sezingxenye ezimbili singavulwa ngokuqondile ngaphandle kosizo lwethuluzi lesibhamu sokushisa. Intengo ibiza kakhulu kunocezu olulodwa, i-SMT ishiselwe ku-PCB, ebizwa ngeShielding Frame, okungenhla kubizwa nge-Shielding Cover, ngqo ku-Shielding Frame, kulula ukuyiqaqa, ngokuvamile uhlaka olulandelayo lubizwa ngokuthi uhlaka oluvikelayo, olungenhla. Ikhava ibizwa nge-shielding cover. Uhlaka lunconywa ukusebenzisa ithusi elimhlophe, ithini ingcono; Ikhava ingenziwa nge-tinplate, eshibhile kakhulu. Izingcezu ezimbili zingasetshenziswa ekuqaleni kwephrojekthi ukuze kube lula ukulungisa iphutha, ukulinda ukuzinza kokulungiswa kwamaphutha, bese ucabangela ukusetshenziswa kwesiqephu esisodwa ukunciphisa izindleko.
