"Kungani ishaja ye-2.4A efanayo, imakethe izoba nezinhlobonhlobo zamanani avelayo?"
Ngikholwa ukuthi abangani abaningi abathenge omakhalekhukhwini namashaja ekhompyutha bebenokungabaza okunjalo. Kubonakala sengathi umsebenzi ofanayo weshaja, intengo ivame ukuba ngumehluko wezwe. Pho kungani kunjalo? Uphi umehluko ngentengo? Yini okufanele ngiyinake lapho ngikhetha ishaja? Namuhla ngizokuxazululela le mfihlakalo.
1 Iprimiyamu yomkhiqizo
Amashaja emakethe angahlukaniswa abe yizigaba ezintathu: amabhrendi oqobo, ezinkampani zangaphandle, amabhrendi ahlukahlukene. Ngokuvamile, ngokuya ngenani lokukala, okwangempela > amabhrendi ezinkampani zangaphandle > amabhrendi axubile.
Ishaja yasekuqaleni ekuthengweni kwezingxenye eziyinhloko ngokuvamile izofika nayo, kodwa kukhona ezinye izinhlobo ezingathumeli, njenge-Apple, futhi ngenxa yesici seprimiyamu yomkhiqizo, intengo ivame ukuba phezulu uma uthenga.
Imikhiqizo yezinkampani zangaphandle yimikhiqizo ekhiqizwe yimikhiqizo yedijithali yezobuchwepheshe, isitayela sihluke kakhulu kunesokuqala, intengo nayo iyathengeka kakhulu, iba yisinqumo sabathengi abaningi. Kodwa-ke, ikhwalithi yemikhiqizo yezinkampani zangaphandle nayo iphezulu futhi iphansi, abakhiqizi abakhulu, ngesitifiketi esigunyaziwe semikhiqizo ekuphepheni kwalabo abavikeleke kakhulu.
Ishaja iyishaja yezitolo eziseceleni komgwaqo, empeleni awazi ukuthi ikhiqizwa yiphi, le mikhiqizo ivamise ukuba ngenxa ye-crotch ebonakalayo noma ubuciko obuqinile kanye nezingozi zokuphepha, akunconywa ukukhetha.
2. Izinto ezihlukene kanye nobuciko
Ungayibheki ishaja encane, ukwakheka kwayo kwesekethe yangaphakathi, izinto zokwakha kanye nomklamo womsebenzi, kuwukunakekela okukhulu. Amashaja ekhwalithi ephezulu, isakhiwo sangaphakathi sezinto eziphelele, ezenziwe kahle, izindleko eziphakeme ngokwemvelo. Futhi amashaja ekhwalithi ephansi ukuze kwehliswe izindleko ngokuvamile ancipha kuma-transformer, izintambo, ama-capacitor nama-inductors.
Isibonelo, i-transformer yangaphakathi, amashaja ekhwalithi enhle ngokuyisisekelo azosebenzisa ukuqhutshwa okuhle, umthamo omkhulu wamanje wokuthwala, ukuzinza okushisayo kwempahla yethusi ehlanzekile, kanye namashaja ahlukahlukene avame ukumbozwa ngethusi aluminium impahla, conductivity ongaphakeme, ukuzinza ezishisayo buthaka.
Esinye isibonelo ibhodi lokuphrinta, amashaja ekhwalithi enhle azosebenzisa izinga lokushisa eliphezulu, i-flame retardant, amabhodi wesifunda aphrintiwe we-PCB angashaqeki, kuyilapho amashaja ahlukahlukene evamise ukushuba, avutha kalula futhi kulula ukuwaphula, izinga lokulahlekelwa kwesifunda liyibhodi le-PCB yengilazi ephezulu. . Ukusetshenziswa isikhathi eside kungenzeka kulimaze ibhethri yefoni, futhi kuholele nasekushiseni okuzenzakalelayo, ukuvuza nezinye izingozi zokuphepha.
3. Inani lezixhumanisi lihlukile
Ngokungeziwe kumashaja ethu embobo eyodwa avame ukusetshenziswa, abasebenzisi abaningi manje basebenzisa amashaja anezimbobo eziningi.
Inzuzo yamashaja anezimbobo eziningi ukuthi uma udinga ukushaja amadivaysi amaningi ngesikhathi esisodwa, kodwa ishaja eyodwa kuphela noma ipulaki engakwazi ukuthwala amashaja amaningi, yisebenzise njengesivumelwano osiqedile.
