Izithiyo zingase kuhlangatshezwane nazo ngesikhathi sokukhiqizwa kwebhodi lesifunda elivumelana nezimo

Amabhodi esekethe aguquguqukayo, aziwa nangokuthi amasekethe aguquguqukayo noma amabhodi wesekethe aphrintiwe (ama-PCB), ayizingxenye ezibalulekile kumishini eminingi kagesi. Ngokungafani namasekhethi aqinile, amasekhethi aguquguqukayo angagoba, asonteke futhi agoqe, awenze alungele izinhlelo zokusebenza ezidinga imiklamo eyinkimbinkimbi noma izithiyo zesikhala.Kodwa-ke, njenganoma iyiphi inqubo yokukhiqiza, ezinye izinselele zingavela ngesikhathi sokukhiqizwa kwamabhodi wesifunda aguquguqukayo.

Enye yezinkinga ezinkulu okubhekwana nazo ngesikhathi sokukhiqiza ubunkimbinkimbi bokuklama amasekethe aguquguqukayo.Ngenxa yokuguquguquka kwawo, lawa mabhodi ngokuvamile adinga izakhiwo eziyinkimbinkimbi nezikhethekile. Ukuklama isifunda esingagotshwa ngaphandle kwanoma yimuphi umthelela omubi ekuxhumekeni kukagesi noma izingxenye kuwumsebenzi onzima. Ukwengeza, ukuqinisekisa ukuthi isifunda esiguquguqukayo singahlangabezana nemininingwane edingekayo yokusebenza kukagesi kwengeza isendlalelo esengeziwe sobunzima.

Esinye isithiyo okuhlangatshezwane naso ngesikhathi sokukhiqizwa kwebhodi lesifunda esiguquguqukayo ukukhetha izinto ezibonakalayo.Amasekhethi aguqukayo ngokuvamile ahlanganisa izendlalelo eziningi zefilimu ye-polyimide, imikhondo yethusi, nezinto zokunamathisela. Lezi zinto zidinga ukukhethwa ngokucophelela ukuze kuqinisekiswe ukuhambisana nokuthembeka. Ukukhetha okokusebenza okungalungile kungase kubangele ukungaguquguquki kahle, ubude bempilo bufinyezwe, noma ukwehluleka kwebhodi lesifunda.

Ukwengeza, ukugcina ukunemba kwephethini yesifunda ngesikhathi sohleloinqubo yokukhiqizakuyinselele futhi.Ngenxa yokuguquguquka kwalawa mabhodi, ukuqondanisa okunembayo kubalulekile. Phakathi nezinqubo ezifana ne-etching, lamination noma ukubhoboza, ukungahambi kahle kungase kwenzeke, okuholela ekuziphatheni okubi noma ngisho neziyingi ezimfushane. Abakhiqizi badinga ukuqinisekisa ukuthi kunezinyathelo eziqinile zokulawula ikhwalithi ukuze kuncishiswe izinkinga zokungaqondani kahle.

Enye inkinga evamile ebhekana nayo ngesikhathi sokukhiqizwa kwebhodi lesifunda eliguquguqukayo ukwethembeka kwe-adhesive ebamba izendlalelo ndawonye.I-adhesive idinga ukunikeza isibopho esiqinile nesihlala isikhathi eside phakathi kwezendlalelo ngaphandle kokuphazamisa ukuguquguquka kwesekethe. Ngokuhamba kwesikhathi, ukushintsha kwezinga lokushisa, umswakama, noma ukucindezeleka kwemishini kungathinta ubuqotho be-adhesive, kubangele ibhodi ukuba linciphise noma lihluleke.

Izifunda eziguquguqukayo nazo ziletha izinselele ngesikhathi sokuhlolwa nokuhlolwa.Ngokungafani namabhodi esekethe aqinile, amasekhethi aguquguqukayo awakwazi ukucindezelwa kalula noma avikelwe ngesikhathi sokuhlolwa. Ukuqinisekisa ukuhlolwa okunembile nokuthembekile, ukunakekelwa okwengeziwe kuyadingeka, okungadla isikhathi futhi kube nzima. Ukwengeza, ukukhomba amaphutha noma amaphutha kumasekhethi aguquguqukayo kungaba inselele kakhulu ngenxa yemiklamo yawo eyinkimbinkimbi kanye nezakhiwo ezinezendlalelo eziningi.

Ukuhlanganisa izingxenye kumabhodi esekethe aguquguqukayo nakho kudala izinkinga.Izingxenye ezincane zokukhweza ngaphezulu ezinezwi elihle zidinga ukubekwa okunembe kuma-substrates aguquguqukayo. Ukuvumelana nezimo kwamabhodi esekethe kwenza kube inselele ukugcina ukunemba okudingekayo ngesikhathi sokubekwa kwengxenye, okwandisa ingcuphe yokutsheka kwengxenye noma ukungahambi kahle.

Okokugcina, isivuno sokukhiqiza samabhodi wesifunda aguquguqukayo singaba ngaphansi uma kuqhathaniswa namabhodi aqinile.Izinqubo eziyinkimbinkimbi ezihilelekile, ezifana ne-multi-layer lamination kanye ne-etching, zakha amandla aphezulu okukhubazeka. Isivuno singase sithintwe izinto ezifana nezakhiwo ezibonakalayo, okokusebenza kokukhiqiza, noma izinga lekhono lomsebenzisi. Abakhiqizi badinga ukutshala imali kubuchwepheshe obuthuthukisiwe kanye nokuthuthukiswa kwenqubo eqhubekayo ukuze bakhulise okukhiphayo futhi banciphise izindleko zokukhiqiza.

Sekukonke, inqubo yokukhiqiza ibhodi lesifunda eguquguqukayo ayinazo izinselele zayo.Izinkinga eziningi zingavela, kusukela ezidingweni zedizayini eziyinkimbinkimbi kuya ekukhethweni kwezinto ezibonakalayo, kusukela ekunembeni kokuqondanisa kuya ekuthembekeni kwesibopho, kusukela ebunzimeni bokuhlola ukuya ekuhlanganisweni kwezingxenye, kanye nesivuno esiphansi sokukhiqiza. Ukunqoba lezi zithiyo kudinga ulwazi olujulile, ukuhlela ngokucophelela, kanye nokuthuthukiswa okuqhubekayo kwezobuchwepheshe bokukhiqiza. Ngokubhekana ngokuphumelelayo nalezi zinselele, abakhiqizi bangakhiqiza amabhodi wesifunda asezingeni eliphezulu futhi anokwethenjelwa ezinhlobonhlobo zezicelo embonini ye-electronics.
