Ukucutshungulwa kwe-PCBA kubuye kwaziwe ngokuthi yi-chip processing, ungqimba olungaphezulu olungaphezulu lubizwa ngokuthi ukucutshungulwa kwe-SMT, ukucubungula kwe-SMT, okuhlanganisa i-SMD, i-plug-in ye-DIP, ukuhlolwa kwe-post-solder nezinye izinqubo, isihloko samaphedi awekho ethini ikakhulukazi Isixhumanisi sokucubungula i-SMD, unamathisele ogcwele izingxenye ezihlukahlukene zebhodi uvela ebhodini lokukhanya le-PCB, ibhodi lokukhanya le-pcb linamaphedi amaningi (ukubekwa kwezingxenye ezihlukahlukene), nge-hole (plug-in), ama-pads awawona okwenzeka njengamanje Isimo sincane, kodwa ku-SMT ngaphakathi futhi kukhona isigaba sezinkinga zekhwalithi.
Izinkinga zenqubo yekhwalithi, kufanele zibe yizimbangela eziningi, ohlelweni lwangempela lokukhiqiza, zidinga ukusekelwe ekuhlangenwe nakho okufanelekile ukuze kuqinisekiswe, ngamunye ngamunye ukuxazulula, ukuthola umthombo wenkinga nokuxazulula.
I. Ukugcinwa okungalungile kwe-PCB
Ngokuvamile, i-spray tin ngesonto izovela njenge-oxidation, ukwelashwa kwendawo ye-OSP kungagcinwa izinyanga ezingu-3, ipuleti legolide elishonile lingagcinwa isikhathi eside (okwamanje izinqubo zokukhiqiza ze-PCB ziningi)
II.Ukusebenza okungalungile
Indlela ye-welding engalungile, amandla okushisa akwanele, izinga lokushisa elanele, isikhathi sokugeleza kabusha esanele nezinye izinkinga.
III.Izinkinga zokuklama kwe-PCB
Iphedi ye-solder kanye nendlela yokuxhuma isikhumba sethusi izoholela ekushiseni kwephedi okwanele.
IV.Inkinga ye-flux
Umsebenzi we-Flux akwanele, ama-PCB pads kanye ne-electronic components soldering bit ayisusi impahla ye-oxidation, i-solder joints bit flux ayanele, okuholela ekumanzini okungekuhle, ukugeleza kwe-tin powder akunyakaziswanga ngokugcwele, ukwehluleka ukuhlanganiswa ngokugcwele ku-flux. (i-solder inamathisela emuva esikhathini sezinga lokushisa sifushane)
V. PCB ibhodi ngokwayo inkinga.
Ibhodi le-PCB efektri ngaphambi kokuthi i-pad surface oxidation ingalashwa
VI.Geza kabusha ihhaviniizinkinga
Isikhathi sokushisa sifushane kakhulu, izinga lokushisa liphansi, ithini alikakancibiliki, noma isikhathi sokushisa side kakhulu, izinga lokushisa liphezulu kakhulu, okuholela ekuhlulekeni komsebenzi we-flux.
Kusukela kulezi zizathu ezingenhla, ukucutshungulwa kwe-PCBA kuwuhlobo lomsebenzi angeke kube budlabha, isinyathelo ngasinye sidinga ukuqina, ngaphandle kwalokho kunenani elikhulu lezinkinga zekhwalithi ekuhlolweni kokushisela kamuva, khona-ke kuzobangela inani elikhulu kakhulu labantu, ukulahlekelwa kwezimali nezinto ezibonakalayo, ngakho ukucubungula kwe-PCBA ngaphambi kokuhlolwa kokuqala kanye nocezu lokuqala lwe-SMD luyadingeka.
