Ukulungiswa kunye nokugcinwa
55. Ungawulungisa njani umonakalo owenzekileyo kwiingubo zePCBA?
Coca indawo eyonakeleyo nge-ethyl acetate, uyicoce kwakhona, uze uyixube/uyixube ukuze ilungiswe, uyilungise ngokwemigangatho.
56. Ungalwenza njani uhlolo lomgangatho kwiingubo ezilungisiweyo?
Hlola inkangeleko, ubukhulu, ukunamathela (uvavanyo olunqamlezileyo), kunye nokumelana nobushushu ukuqinisekisa ukuba ipeyinti yoqobo iyahambelana nepeyinti yokuqala.
57. Ngaba iingubo ezindala zingaphinda zigqunywe?
Ukuba i-substrate kunye nezinto ezisetyenzisiweyo zikwimeko entle, susa i-coating endala ngamakhemikhali/ngoomatshini uze uyifake kwakhona, uqaphele ukuba ayizukulimaza ibhodi yesekethe.
58. Ungayigcina njani i-PCBA ngeengubo ezigqunyiweyo?
Kuphephe ukukrwela, hlola rhoqo inkangeleko, lungisa umonakalo ngokukhawuleza, kwaye ugcine kwindawo eyomileyo, engenakonakalisa igesi.
59. Ungajongana njani nokwehla kokusebenza kweengubo ngexesha lokusetyenziswa?
Hlalutya izizathu (umz., ukwaluphala kwendalo). Iingxaki zasekuhlaleni zingalungiswa; ukonakala okukhulu ngokubanzi kufuna uvavanyo lokuphinda kufakwe i-coating okanye ukutshintshwa kwe-PCBA.
60. Ungawuthintela njani umonakalo wesibini kwi-PCBA ngexesha lokulungiswa?
Sebenzisa izixhobo ezichasene nokunganyakazi, lawula idosi yesixhobo sokucoca, kwaye uchaze ngokuchanekileyo ububanzi bokugquma ukulungisa ukuthintela ungcoliseko lwendawo olungakhuseliyo.
