Umgangatho kukusinda kweshishini, ukuba ulawulo lomgangatho alukho, ishishini aliyi kuya kude, umzi-mveliso wePCB ukuba ufuna ukulawula umgangatho webhodi yePCB, ungalawula njani?
Sifuna ukulawula umgangatho webhodi ye-PCB, kufuneka kubekho inkqubo yokulawula umgangatho, ngokuqhelekileyo kuthiwa yi-ISO9001, ngokuqhelekileyo ingqikelelo yenkqubo yokulawula umgangatho yimilinganiselo yomgangatho wexesha lokwenene kunye nokulawula, xa into enye inemigangatho yokulinganisa edibeneyo kwaye imigangatho yokubeka iliso, ufuna ukwenza umsebenzi olungileyo kulula kakhulu.
Lawula umgangatho webhodi ye-PCB, okokuqala kufuneka ube nokuhlolwa komgangatho ongqongqo kwizinto eziphathekayo, kufunyenwe ukuba kukho nayiphi na into engalunganga ekubhaliseni kwangexesha, ukunika ingxelo, kunye nokubeka phambili isisombululo, kuphela ukuqinisekisa umgangatho wezinto ekrwada, kunokwenzeka. ukufumana umgangatho olungileyo PCB, ukuba umgangatho wezinto ekrwada akuqinisekwanga, ukwenza PCB enkulu usenokuba neengxaki ezahlukeneyo, ezifana amaqamza, delamination, crack, babe warped, ingxaki ubukhulu ukungalingani.Ngoko ke imathiriyeli ekrwada kufuneka ihlolwe ngokungqongqo ukunika ukhuseleko lwemveliso ngasemva.
Xa umgangatho wezinto eziluhlaza uqinisekisiwe, kuyimfuneko ukunikela ingqalelo kwiingxaki eziza kwenzeka kwinkqubo yokuvelisa.Ukuhlolwa komgangatho kunye nokuhlolwa kufuneka kuqhutywe kwikhonkco lenkqubo nganye kwinkqubo yokuvelisa ukuqinisekisa ukuba inkqubo nganye inemiyalelo yokusebenza, ukwenzela ukuba kube lula ulawulo olubanzi lomgangatho we-PCB.
Emva kokugqitywa kwemveliso, uhlolo lwesampulu kufuneka lwenziwe.Nangona ukuhlolwa komgangatho kuye kwenziwa kwizinto eziluhlaza kunye nenkqubo yokuvelisa, kusekho izizathu ezahlukeneyo zokukhubazeka.Ngoko ke, ukuhlolwa kwesampulu kufuneka kuqhutywe kwibhetshi yonke yeebhodi zePCB emva kokugqitywa kwemveliso.Kuphela kuxa ireyithi yokupasa yokuhlolwa kweesampulu ifikelela kumgangatho apho aya kuvunyelwa ukuba aphume kumzi-mveliso.Ukuba ireyithi yokupasa yokuhlolwa kwesampulu iyasilela ukufikelela kumgangatho, uhlolo olupheleleyo kunye nokugcinwa kuya kwenziwa, kwaye umgangatho webhodi nganye yePCB uya kuba noxanduva.
