I-Q & A Indlela yokuvavanya iHole Wall Wall kunye neMigaqo eNxulumene noko
Ungayifumana njani indlela yokuvavanya umxokelelwane weHole Wall kunye neNgcaciso yeDilesi? Udonga lweHole lususa oonobangela kunye nezisombululo?
Uvavanyo lokuTsala udonga lwalusetyenziswa ngaphambili ngenxa yezinto zokuhamba-hamba ukuze uhlangane neemfuno zokuhlanganisana. Uvavanyo ngokubanzi kukuthengisa i-wire kwibhodi ye-PCB ngemingxunya kwaye emva koko ulinganise ixabiso lokukhupha ngethayile. Vulalela kumava, amaxabiso ngokubanzi aphezulu kakhulu, owenza phantse akukho ngxaki kwisicelo. Iinkcazo zemveliso ziyahluka ngokwe
Kwiimfuno ezahlukeneyo, kuyacetyiswa ukuba kubhekiswe kwiinkcazo ezinxulumene ne-IPC.
Ingxaki yokwahlulahlula umngxunya ngumba ombi we-Adhesion, obangelwe zizizathu ezibini eziqhelekileyo, okokuqala ngqalelo ye-desmear ehlwempuzekileyo (desmear) yenza uxinzelelo alonelanga. Enye yinkqubo yokubeka i-coperroper yoshicilelo okanye ngokuthe ngqo, umzekelo: ukukhula kwendawo enkulu, i-balky swick iya kuba yimlingane. Ngokuqinisekileyo kukho ezinye izinto ezinokubakho ezinokubakho ingxaki enjalo, nangona zizinto zimbini zezona ngxaki zixhaphakileyo.
Kukho izinto ezimbini ezingalunganga zokwahlulahlula umngxunya, okokuqala yimeko yokusebenza kovavanyo okanye ngokungqongqo, kuya kukhokelela kwibhodi ye-PCB ayinakukwazi ukumelana noxinzelelo lwe-PCB ukuze yahlulwe. Ukuba le ngxaki kunzima ukusombulula, mhlawumbi kuya kufuneka uguqule izinto zamilenze zokufezekisa uphuculo.
Ukuba ayisiyo ingxaki engasentla, ikakhulu ibangelwa kukunamathela olihlwempu phakathi komngxunya nodonga lomngxunya. Izizathu ezinokubakho zeli nxalenye zibandakanya ukungakhathali kodonga lomngxunya, ubukhulu bokugqithisa bobhedu, kunye neziphene zekhemikhali ezibangelwa yinkqubo yobhedu. Zonke ezi zisizathu esinokwenzeka. Ewe kunjalo, ukuba umgangatho wokuqhuba uhlwempuzekile, ukwahluka kodonga lomngxunya kunokubangela iingxaki ezinjalo. Njengomsebenzi osisiseko wokusombulula ezi ngxaki, kufanele ukuba kukuqala ukuqinisekisa isizathu sengcambu uze ujongane nomthombo wesizathu ngaphambi kokuba iconjululwe ngokupheleleyo.
