Ungavivinya kanjani i-Hole Wall Tensile nehlobene Imininingwane? Udonga lomgodi ukhiphe izimbangela nezisombululo?
Ukuhlolwa kodonga lomuntu odongeni kwasetshenziswa ngaphambili ngezitho ze-pay ukufeza izidingo zokuhlanganisa. Ukuhlolwa okujwayelekile kuwukuxoxa ngocingo ku-PCB Board ngokusebenzisa izimbobo besekala ukuthi kube yinani lokukhipha imitha yengxabano. Kuvumelana kokuhlangenwe nakho, amanani ajwayelekile aphezulu kakhulu, okwenza cishe zinkinga ekusetshenzisweni. Ukucaciswa komkhiqizo kuyahlukahluka ngokuya
Kuya kwizidingo ezihlukile, kunconywa ukubhekisela kwimininingwane ehlobene ne-IPC.
Inkinga yokwahlukanisa umgodi wokohlukaniso yinkinga yokunamathela kabi, okuvame ukubangelwa yizizathu ezimbili ezijwayelekile, okokuqala munye ubamba le-Desmear empofu (Desmear) empofu enze ukungezwani akwanele. Enye inqubo ye-electroless yethusi Pepper Plating noma i-Plated Eqondile Plated, isibonelo: Ukukhula kwesitaki esinamandla, esinobukhulu kuzoholela ekunamatheks. Vele kukhona ezinye izinto ezingaba khona ezingenza le nkinga, noma kunjalo lezi zinto ezimbili yizinkinga ezivame kakhulu.
Kukhona ababi bokuhlukana kodonga lodonga, okokuqala munye ngokweqiniso kuyindawo yokusebenza esebenza kahle kakhulu noma eqinile, kuzoholela ebhodini le-PCB alikwazi ukumelana nokuxineka ngokomzimba ukuze lihlukaniswe. Uma le nkinga kunzima ukuyixazulula, mhlawumbe kufanele ushintshe izinto ze-liminate ukuze uhlangabezane nokwenza ngcono.
Uma kungeyona inkinga engenhla, kungenxa yokunamathela okumpofu phakathi kwethusi lomgodi nodonga lomgodi. Izizathu ezingaba khona zale ngxenye zifaka ukuqina okunganele kodonga lomgodi, ubukhulu obukhulu bokubumba kwamakhemikhali, kanye nokulimala okubangelwa ukwelashwa kwenqubo yamakhemikhali empofu. Zonke lezi yisizathu esingenzeka. Vele, uma ikhwalithi yokumba imbi, ukwahluka kwesimo kodonga lomgodi nakho kungadala izinkinga ezinjalo. Ngokuqondene nomsebenzi oyisisekelo kakhulu ukuxazulula lezi zinkinga, kufanele kube okokuqala ngqa ukuqinisekisa imbangela imbangela bese ubhekana nomthombo wembangela ngaphambi kokuthi ixazululwe ngokuphelele.
