Amabhodi esekethe aphrintiwe (ama-PCB) ayingxenye ebalulekile yobuchwepheshe besimanje. Izicelo zabo zisukela kuma-smartphones namakhompyutha kuya kumishini yezokwelapha nezinhlelo zezimoto. Kunezinhlobo ezahlukene zama-PCB, enye yazo i-PCB eqinile. Ngenkathi ama-PCB aqinile enikeza izinzuzo eziningi, futhi anemibi yawo.Kulokhu okuthunyelwe kwebhulogi, sizohlola ukonakala kwama-PCB aqinile futhi sihlole izizathu eziwabangela.
1. Ukuvumelana nezimo okulinganiselwe:
Ububi obukhulu bama-PCB aqinile ukuguquguquka okulinganiselwe. Njengoba igama liphakamisa, ama-PCB aqinile awanakho ukuguquguquka futhi awakwazi ukugoba noma ukugoba. Kwezinye izinhlelo zokusebenza, lokhu kuntuleka kokuguquguquka kungase kube ukuhlehlisa okuphawulekayo. Isibonelo, kubuchwepheshe obugqokekayo noma kumadivayisi adinga ukunyakaza njalo, ama-PCB aqinile angase akhawulele ukuklama okuphelele nokusebenza. Lo mkhawulo ungase uvimbe ukuthuthukiswa kwemishini kagesi emisha kanye necwecwe.
2. Izinselelo zokonga indawo:
Ama-PCB aqinile awongi isikhala njengezinye izinhlobo zama-PCB. Njengoba zingakwazi ukugoba noma ukubunjwa, zidinga indawo eyengeziwe, ekugcineni zithinte ukwakheka okuphelele nokuklama kwemikhiqizo ye-elekthronikhi. Lo mkhawulo ubaluleke kakhulu emishinini emincane noma emishinini enamasekhethi ayinkimbinkimbi, lapho kubalwa khona yonke indawo eyimilimitha. Ngokuvamile abaklami kufanele basebenzele eduze nale mikhawulo, okuholela ebucayini ekusebenzeni okuphelele noma ukwanda kosayizi womkhiqizo wokugcina.
3. Izintambo eziyinkimbinkimbi kanye nokuhlanganisa:
Ama-PCB aqinile ngokuvamile adinga izintambo eziyinkimbinkimbi kanye nokuhlanganiswa kunama-PCB aguquguqukayo. Imvelo eqinile yalawa mabhodi isho ukuthi ukulandelana kwesekethe kufanele kuhanjiswe emiphethweni engashintshi. Lokhu kwenza ukwakheka kwe-PCB kube nzima kakhulu futhi kudle isikhathi, okuholela ekwenyukeni kwezindleko zokukhiqiza. Ukwengeza, ukungakwazi ukugoba ibhodi kwenza kube nzima ukufaka izingxenye ezithile noma izixhumi, okwenza kube nzima nakakhulu inqubo yokuhlanganisa.
4. Ingabhekana nengcindezi yemishini:
Ama-PCB aqinile asengozini yokucindezelwa yimishini kunama-PCB aguquguqukayo. Azikwazi ukumunca ukushaqeka noma ukudlidliza, zonakala kalula, ikakhulukazi ezinhlelweni ezibandakanya ukunyakaza okuvamile noma izici zemvelo. Ukuqina kwe-PCB kungabangela amalunga e-solder ukuthi ahluleke, kubangele izinkinga zokuxhuma futhi kuphazamise ukwethembeka kwesifunda. Lokhu kubi kudinga ukucatshangelwa ngokucophelela lapho kukhethwa uhlobo lwe-PCB lohlelo oluthile.
5. Izindleko eziphakeme:
Ama-PCB aqinile ngokuvamile abiza kakhulu uma kuqhathaniswa nama-PCB aguquguqukayo. Izinqubo zokukhiqiza eziyinkimbinkimbi, izakhiwo eziyinkimbinkimbi kanye nezindleko eziphezulu zempahla kuholela emananini aphezulu. Lokhu kungaba yingozi enkulu kumaphrojekthi anesabelomali esiqinile noma emikhiqizweni lapho izindleko zicatshangelwa kakhulu. Kodwa-ke, kubalulekile ukuqaphela ukuthi izidingo ezithile zephrojekthi kufanele ziqondise njalo inqubo yokukhetha, kucatshangelwa zonke izici, kuhlanganise nokusebenza kahle kwezindleko.
Ngokufigqiwe
Nakuba ama-PCB aqinile anezinzuzo mayelana nokuqina kwesakhiwo kanye nokuzinza, aphinde abe nokubi okuthile.Ukuvumelana nezimo okulinganiselwe, izinselele zokonga isikhala, umzila oyinkimbinkimbi nokuhlanganisa, ukuzwela ekucindezelekeni komshini, nezindleko eziphakeme zonke izici okufanele zicatshangelwe lapho kukhethwa uhlobo lwe-PCB lohlelo oluthile. Yonke iphrojekthi yokuklama idinga ukuhlolwa ngokucophelela kwezinzuzo nezingozi, kugcinwe izidingo ezithile kanye nezingqinamba engqondweni. Umgomo omkhulu uwukuthola uhlobo lwe-PCB olufanele kakhulu ukuze kuqinisekiswe ukusebenza kahle, ukusebenza kanye nokusebenza kahle kwezindleko zohlelo olunikeziwe.
