Izwe lobuchwepheshe lihlala livela futhi ngakho isidingo samabhodi esekethe aphrintiwe athuthuke kakhulu nasezingeni eliphezulu (PCBs). Ama-PCB ayingxenye ebalulekile yemishini kagesi futhi adlala indima ebalulekile ekuqinisekiseni ukusebenza kwawo.Ukuze kuhlangatshezwane nesidingo esikhulayo, abakhiqizi kufanele bahlole izinqubo ezikhethekile nobuchwepheshe, obufana nokungaboni ngekhava yethusi, ukuze kuthuthukiswe ukusebenza kwe-PCB. Kulokhu okuthunyelwe kwebhulogi, sizohlola amathuba okusebenzisa lezi zinqubo ezikhethekile ekukhiqizeni i-PCB.
Ama-PCB enziwa ngokuyinhloko kusetshenziswa izendlalelo zethusi ezilamiwe ku-substrate engaphenduki, evame ukwakhiwa nge-epoxy eqiniswe yi-fiberglass.Lezi zingqimba zinamathiselwe ukuze zenze ukuxhunywa kukagesi okudingekayo kanye nezingxenye ebhodini. Nakuba le nqubo yokukhiqiza evamile iphumelela ezinhlelweni eziningi, amanye amaphrojekthi angase adinge izici ezengeziwe kanye nokusebenza okungenakufezwa ngezindlela ezivamile.
Inqubo eyodwa eyisipesheli iwukuhlanganisa izimpumputhe ngekhava yethusi ku-PCB.Izimbobo eziyizimpumputhe ziyizimbobo ezingadluleli ezinwebeka kuphela ekujuleni okuthile ngaphakathi kwebhodi kunokudlula ngokuphelele ebhodini. Lezi zindlela zokungena ezingaboni zingagcwaliswa ngethusi ukuze zenze ukuxhumana okuphephile noma ukumboza izingxenye ezibucayi. Le nqubo iwusizo ikakhulukazi lapho isikhala sinomkhawulo noma izindawo ezihlukile ku-PCB zidinga amazinga ahlukene wokusebenza noma ukuvikela.
Enye yezinzuzo eziyinhloko zamakhethini ngokusebenzisa izembozo zethusi ukwethembeka okuthuthukisiwe.Isigcwalisi se-copper sinikeza ukusekelwa okuthuthukisiwe kwemishini ezindongeni zembobo, kunciphisa ubungozi be-burrs noma ukulimala kwembobo ngesikhathi sokukhiqiza. Ukwengeza, ukugcwalisa kwethusi kuhlinzeka nge-conductivity eyengeziwe yokushisa, okusiza ukuqeda ukushisa okuvela engxenyeni, ngaleyo ndlela ukwandisa ukusebenza kwayo jikelele nokuphila isikhathi eside.
Kumaphrojekthi adinga izimpumputhe ngokusebenzisa izembozo zethusi, imishini ekhethekile nobuchwepheshe kuyadingeka ngesikhathi sokukhiqiza.Ngokusebenzisa imishini yokumba ethuthukisiwe, izimbobo eziyimpumputhe ezinobukhulu obuhlukahlukene kanye nokuma zingabholwa ngokunembile. Le mishini ifakwe izinhlelo zokulawula ukunemba eziqinisekisa imiphumela engaguquki nethembekile. Ukwengeza, inqubo ingase idinge izinyathelo eziningi zokumba ukuze kuzuzwe ukujula okufunayo kanye nokuma kwembobo eyimpumputhe.
Enye inqubo ekhethekile ekukhiqizeni i-PCB ukuqaliswa kwe-vias engcwatshiwe.Ama-vias angcwatshwe yizimbobo ezixhuma izingqimba eziningi ze-PCB kodwa ezinganweleli kuze kube sezindlalelo zangaphandle. Lobu buchwepheshe bungadala amasekethe anezingqimba eziningi eziyinkimbinkimbi ngaphandle kokukhulisa usayizi webhodi. Ama-Vis angcwatshwayo akhuphula ukusebenza nokuminyana kwama-PCB, okuwenza abe wusizo kumishini yesimanje kagesi. Kodwa-ke, ukusebenzisa ama-vias angcwatshwe kudinga ukuhlela ngokucophelela kanye nokwakhiwa okunembayo, njengoba izimbobo zidinga ukuhambisana kahle futhi zibhojwe phakathi kwezingqimba ezithile.
Inhlanganisela yezinqubo ezikhethekile ekukhiqizeni i-PCB, njengokungaboni ngezembozo zethusi kanye nama-vias angcwatshwe, ngokungangabazeki kwandisa inkimbinkimbi yenqubo yokukhiqiza.Abakhiqizi badinga ukutshala imali ezintweni ezithuthukisiwe, baqeqeshe abasebenzi ngobuchwepheshe bezobuchwepheshe, futhi baqinisekise ukuthi kunezinyathelo eziqinile zokulawula ikhwalithi. Kodwa-ke, izinzuzo namandla athuthukisiwe ahlinzekwa yilezi zinqubo awenza abaluleke kakhulu kwezinye izinhlelo zokusebenza, ikakhulukazi lezo ezidinga ukujikeleza okuthuthukisiwe kanye ne-miniaturization.
Ngokufigqiwe, izinqubo ezikhethekile zokwenziwa kwe-PCB, ezifana nezimpumputhe ngezigqoko zethusi nama-vias angcwatshwe, azenzeki kuphela kodwa ziyadingeka kwamanye amaphrojekthi.Lezi zinqubo zithuthukisa ukusebenza kwe-PCB, ukwethembeka, nokuminyana, zizenze zifaneleke kumadivayisi kagesi athuthukile. Nakuba zidinga ukutshalwa kwezimali okwengeziwe kanye nezinto zokusebenza ezikhethekile, zinikeza izinzuzo ezingaphezu kwezinselele. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, abakhiqizi kumele bahambisane nalezi zinqubo ezikhethekile ukuze bahlangabezane nezidingo eziguqukayo zemboni.
