Uyini umehluko phakathi kwe-PCB ne-PCBA?

I-PCB: Ibhodi yokujikeleza ephrintiwe yibhodi engenazo izingxenye ze-elekthronikhi. Ihlanganiswa ikakhulukazi i-substrate, i-Copper Foil Circuit nePad. Umjikelezo wakheka engxenyeni engezansi ngokusebenzisa amakhemikhali e-etching kanye nezinye izinqubo, njengesigaba esingenalutho, kuphela uhlaka neziteshi zokuxhumana ezimisiwe, ukuhlinzeka indawo yezinto ezilandelayo ze-elekthronikhi ku- "ukwenza".

I-PCBA E-Infrared: Iphrintiwe IBHODI YOBHODI BOKWENZA UMkhiqizo OQALIWE ngemuva kokufaka izakhi ezahlukahlukene ze-elekthronikhi (njengama-capacitors, ama-capacitors, njll. Kuyafana nokuhlela abalingisi (izakhi ze-elekthronikhi) esiteji, kanye nokuvuselelwa (ukulungisa iphutha), futhi kungakwazi ngqo "(qaphela ukusebenza kwemikhiqizo ye-elekthronikhi).

2, Ukukhiqiza inqubo yenqubo

I-PCB : I-Okokuqala i-Design, lapho onjiniyela basebenzisa isoftware ekhethekile ukuhlela ukuqondiswa kwemigqa nokubekwa kwezakhi. Ngemuva kwalokho inqubo yokukhiqiza, kufaka phakathi ukukhiqizwa komjikelezo wangaphakathi, njengokusetshenziswa kwe-litholwography, ubuchwepheshe be-etching ukwenza umjikelezo wangaphakathi epuletini ye-clad yethusi; Ngemuva kwalokho i-lamination (yeBhodi Ehlukahlukene Ehlukahlukene), isendlalelo sangaphakathi sesifunda kanye nesendlalelo sokufakelwa sahlanya; Emva kwalokho, ukukhiqizwa kwesekethe indawo yangaphandle kanye nokwelashwa komhlaba, njengokuthwebula i-tin, amapuleti egolide ukuthuthukisa ukusebenza kwe-pad.

I-PCBA: Ukuthengwa kwezakhi kokuqala, khetha izakhi ezihlangabezana nezidingo. Ngemuva kwalokho i-Surface Mount Technology (SMT) noma imodi ye-plug-in (dip) isetshenziselwa ukukhweza izakhi kwi-PCB. I-SMT ikhweza izingxenye ezincane ngokunembile ngemishini ezenzakalelayo, futhi ukucwilisa kusetshenziselwa ikakhulukazi ukufakwa kwe-PIN yezakhi ezinkulu. Ngemuva kwalokho, kwenziwa i-solded, izinto ze-SMT zibonisa indersed, futhi izakhi ze-dip zingamanzi athengiswayo noma athengiswe ngesandla. Ekugcineni, ukuqinisekiswa kwenziwa, kufaka phakathi ukuhlolwa kokubukeka kanye nokuhlolwa kukagesi.

3, Izimo Zokusebenza:

I-PCB: Esesigabeni sokuqala sokwakhiwa komkhiqizo we-elekthronikhi, kusetshenziselwa ukuqinisekisa ukuthi kungenzeka yini ukuthi ukwakheka kwesifunda futhi kunqume ukuthi ngabe ukwakheka kwesekethe kunengqondo yini. Ngasikhathi sinye, emisebenzini ethile elula yokwenza imisebenzi ye-elekthronikhi noma izimo zemfundo, njengebhodi lokujikeleza eliyisisekelo labasebenzisi ukufaka izakhi futhi bathole inqubo yokukhiqiza ngogesi.

I-PCBA: Isetshenziswa kabanzi kwimikhiqizo ehlukahlukene ye-elekthronikhi evuthiwe, efana namafoni ahlakaniphile, amakhompyutha wethebhulethi, imishini yokulawula izimboni, njll. Lemikhiqizo yesekethe idinga ukuthi i-Complents, i-PCBA vele ihlangabezane nalokhu kufunwa, it Ingxenye esemqoka yemikhiqizo ye-elekthronikhi ukuze ibone umsebenzi.
