I-Q&A UVavanya Njani Ukuqina Kodonga Lomngxuma kunye NeeNgcaciso eziNxulumeneyo
Ukuvavanya njani ukuqina kodonga lomngxuma kunye neenkcukacha ezinxulumeneyo?Udonga lomngxuma lukhupha oonobangela kunye nezisombululo?
Uvavanyo lokutsalwa kodonga lomngxuma lwasetyenziswa ngaphambili kwiindawo zokungena emngxunyeni ukuhlangabezana neemfuno zokuhlanganisa.Uvavanyo ngokubanzi kukuthengisa ucingo kwibhodi yePCB ngokusebenzisa imingxunya kwaye emva koko ulinganise ixabiso lokukhupha ngemitha yoxinzelelo.Ngokuvumelana namava, amaxabiso aqhelekileyo aphezulu kakhulu, okwenza ukuba phantse akukho ngxaki kwisicelo.Iimpawu zemveliso ziyahluka ngokwee
kwiimfuno ezahlukeneyo, kuyacetyiswa ukuba ubhekisele kwiinkcukacha ezinxulumene ne-IPC.
Ingxaki yokwahlulwa kodonga lomngxuma ngumba wokuncamathelisa kakubi, okubangelwa ngokubanzi zizizathu ezibini eziqhelekileyo, esokuqala kukubamba i-desmear ehlwempuzekileyo (Desmear) yenza ukutsaleka akwanelanga.Enye yinkqubo yokucola i-electroless copper okanye ngokuthe ngqo igolide ecatshulwe, Umzekelo: ukukhula kobungqingqwa, isitakhi esikhulu kuya kubangela ukuncamathelisa kakubi.Ewe zikho ezinye izinto ezinokuthi zichaphazele ingxaki enjalo, kodwa ezi zinto zimbini zezona ngxaki zixhaphakileyo.
Kukho izinto ezingalunganga ezimbini zokwahlulwa kodonga lomngxunya, eyokuqala ngokuqinisekileyo yindawo yokusebenza yovavanyo enobunzima kakhulu okanye engqongqo, iya kubangela ukuba ibhodi ye-pcb ingakwazi ukumelana noxinzelelo lomzimba ukuze yahlulwe.Ukuba le ngxaki inzima ukuyicombulula, mhlawumbi kufuneka utshintshe izinto ze-laminate ukuhlangabezana nokuphucula.
Ukuba akusiyo ingxaki engentla, ininzi ngenxa yokubambelela kakubi phakathi kobhedu lomngxuma kunye nodonga lomngxuma.Izizathu ezinokwenzeka zale nxalenye ziquka ukungonelanga kodonga lomngxuma, ukutyeba okugqithisileyo kobhedu lwekhemikhali, kunye neziphene zokujongana okubangelwa kunyango lwenkqubo yobhedu yeekhemikhali.Ezi zonke zizizathu ezinokwenzeka.Ngokuqinisekileyo, ukuba umgangatho wokugaya umbi, ukuhluka kwemilo yodonga lomngxuma kunokubangela iingxaki ezinjalo.Ngokuphathelele owona msebenzi usisiseko wokusombulula ezi ngxaki, kufuneka kuqala uqinisekise oyena nobangela uze ujongane nomthombo wonobangela phambi kokuba usonjululwe ngokupheleleyo.
