Ama-electron ezenzakalelayo abhekisela ezintweni zikagesi ezisetshenziswa ezimotweni, okuhlanganisa amamojula okulawula injini, izinhlelo zokuzijabulisa zolwazi, izinhlelo zokuphepha, izinzwa, njll. Lawa madivayisi adinga ukusebenzisa amabhodi esekethe (PCBA) ukuze enze imisebenzi yawo.
I-PCBA, efanele imoto kagesi, idinga izici ezilandelayo:
- Ukuthembeka okuphezulu:Indawo yokusebenza yemikhiqizo ye-elekthronikhi yezimoto iyinkimbinkimbi, futhi izimo zemvelo ezinzima ezifana nokucindezela okukhulu, izinga lokushisa eliphezulu, nomswakama ophezulu. Ngakho-ke, i-PCBA idinga ukwethembeka okuphezulu futhi ingasebenza ngokuzinza.
- Ikhono eliqinile lokulwa nokuphazamiseka:Imoto ifakwe ama-transmitter ahlukahlukene kanye nezamukeli, ezifana nomsakazo, i-radar, i-GPS, njll. Lezi zinokuphazamisa okunamandla, ngakho i-PCBA idinga ukumelana ngempumelelo nalokhu kuphazamiseka.
- Ukunciphisa:Isikhala esingaphakathi emotweni sincane, ngakho i-PCBA idinga ukuba nezici ze-miniaturization, ezingafinyelela umsebenzi wesifunda odingekayo endaweni elinganiselwe.
- Ukusetshenziswa kwamandla okuphansi:Imishini ye-elekthronikhi yemoto idinga ukusebenza ngesikhathi semoto isikhathi eside, ngakho-ke kuyadingeka ukonga amandla nokunciphisa ukusetshenziswa nokugcina ukusetshenziswa kwamandla.
- Ukunakekela:Ukulungiswa kwemishini ye-elekthronikhi yezimoto kudinga ukuba kube lula futhi kusheshe, futhi i-PCBA idinga ukuba nezici zokuqaqa nokulungisa kalula.
Ngokusekelwe kulezi zidingo, i-PCBA, efanele imishini ye-elekthronikhi yezimoto, idinga ukukhetha ukwethembeka okuphezulu kanye nezingxenye ezinhle zokumelana nokushisa, futhi yamukele inqubo yokuklama ekhethekile kanye nenqubo yokukhiqiza ukuze kuqinisekiswe ikhwalithi nokuthembeka kwe-PCBA. Ngesikhathi esifanayo, kuyadingeka ukucabangela ukuhlelwa kwe-PCB kanye nokwenza kahle komugqa ukuze kuqinisekiswe ukuzinza kwayo kanye nokuphikisana nokuphazanyiswa.
Nawa amanye amamodeli e-PCBA asetshenziswa kakhulu kuma-electronics wezimoto:
I-FR-4 Fluoro Material PCBA
Kuyinto ejwayelekile yebhodi lesifunda. Inokumelana nokugqwala okuhle, i-aggressiveness kanye ne-insulation, futhi ingakwazi ukumelana nendawo evamile yokusebenza kwemoto.
I-PCBA enezinga eliphezulu lokushisa
Ifanele izindawo ezinezinga lokushisa eliphezulu emikhiqizweni yezimoto zikagesi. Lolu hlobo lwe-PCBA luvamise ukusebenzisa i-polyimide njenge-substrate material, enokumelana okuhle kwezinga lokushisa eliphezulu.
Isekethe ehlanganisiwe (IC) PBCA
Ilungele ama-elekthronikhi ezimoto afanele izicelo zesekethe ezididiyelwe eziphezulu. Inokusebenza okuhle kakhulu futhi inezinzuzo zejubane eliphezulu, ukuminyana okuphezulu nosayizi omncane.
I-Metal substrate PCBA
Ifanele i-automotive electronics edinga amandla aphezulu nokusebenza kokukhipha ukushisa. I-PCBA enjalo isebenzisa i-aluminiyamu nensimbi yethusi njengezinto ze-substrate, ezinokusebenza okuhle kwe-thermal nokusebenza kokukhipha ukushisa.
PCBA
I-PCBA yakhelwe izinhlelo zokusebenza ezifana nezinhlelo zokuzijabulisa zezimoto, amarekhodi okushayela, amasistimu okuzulazula, njll.
Lezi zinhlobo ze-PCBA zinezici ezihlukile kanye nezimo zohlelo lokusebenza. Bangakhetha imodeli ye-PCBA efaneleke kakhulu ngokwezidingo ezithile ze-elekthronikhi yemoto.
