Emhlanganweni we-PCBA, ukukhethwa kwezinto kubalulekile ekusebenzeni kwebhodi nokuthembeka.Nakhu okucatshangelwayo kokukhetha i-solder, i-PCB kanye nokukhetha kokupakisha:
Ukucatshangelwa kokukhetha i-solder
1. I-Lead Free Solder vs Leaded Solder
I-solder engenamthofu ibaluleke kakhulu ngenxa yobungane bemvelo, kodwa kubalulekile ukuqaphela ukuthi inamazinga okushisa aphezulu e-solder.I-solder eholayo isebenza emazingeni okushisa aphansi, kodwa kunezingozi zemvelo nempilo.2.
2. Iphuzu lokuncibilika
Qinisekisa ukuthi indawo yokuncibilika ye-solder ekhethiwe ifanele izidingo zokushisa zenqubo yokuhlanganisa futhi ngeke ibangele umonakalo wokushisa izingxenye ezibucayi.
3. Uketshezi
Qinisekisa ukuthi i-solder ine-fluidity enhle ukuqinisekisa ukumanzisa okwanele nokuxhumeka kwamalunga e-solder.
4. Ukumelana nokushisa
Ngezinhlelo zokusebenza zokushisa okuphezulu, khetha i-solder enokumelana okuhle kokushisa ukuze uqinisekise ukuzinza okuhlangene kwe-solder.
Ukucatshangelwa kokukhetha impahla ye-PCB
1. I-substrate impahla
Khetha okubalulekile kwe-substrate efanele, okufana ne-FR-4 (i-glass fibre reinforced epoxy resin) noma ezinye izinto ezisebenza ngamaza aphezulu, ngokusekelwe kuzidingo zohlelo lokusebenza nezidingo zemvamisa.
2. Inani Lezendlalelo
Nquma inani lezendlalelo ezidingekayo ukuze i-PCB ihlangabezane nezidingo zomzila wesiginali, izindiza eziphansi kanye namandla.
3. I-impedance yesici
Qonda isici esivimbelayo sento ekhethiwe ye-substrate ukuze uqinisekise ubuqotho besignali futhi ufanise nezidingo zokubhangqa okuhlukile.
4. I-Thermal Conductivity
Kuzinhlelo zokusebenza ezidinga ukuchithwa kokushisa, khetha i-substrate material ene-conductivity enhle ye-thermal ukusiza ukukhipha ukushisa.
Ukucatshangelwa kokukhetha impahla yephakheji
1. Uhlobo lwephakheji
Khetha uhlobo lwephakheji olufanele, njenge-SMD, BGA, QFN, njll., ngokusekelwe ohlotsheni lwengxenye kanye nezidingo zohlelo lokusebenza.
2. Encapsulation material
Qinisekisa ukuthi okokusebenza kwe-encapsulation okukhethiwe kuhlangabezana nezidingo zokusebenza zikagesi nezemishini.Cabangela izici ezifana nebanga lokushisa, ukumelana nokushisa, amandla emishini, njll.
3. Phakamisa ukusebenza okushisayo
Ezingxenyeni ezidinga ukuchithwa kokushisa, khetha impahla yephakheji esebenza kahle ngokushisa okushisayo, noma cabanga ukungeza usinki wokushisa.
4. Usayizi wephakheji kanye nesikhala sephini
Qinisekisa ukuthi usayizi nesikhala sephinikhodi sephakheji ekhethiwe sifanele isakhiwo se-PCB nesakhiwo sengxenye.
5. Ukuvikelwa kwemvelo kanye nokusimama
Cabangela ukukhetha izinto ezivumelana nemvelo ezithobela imithetho nezindinganiso ezifanele.
Lapho ukhetha lezi zinsiza, kubalulekile ukusebenzisana eduze nabakhiqizi nabahlinzeki be-PCBA ukuze uqinisekise ukuthi ukukhethwa kwezinto kuhlangabezana nezidingo zohlelo oluthile.Futhi, ukuqonda izinzuzo, ukungalungi kanye nezici zezinto ezihlukahlukene, kanye nokufaneleka kwazo kwezinhlelo zokusebenza ezahlukene, kuyisihluthulelo sokwenza ukukhetha unolwazi.Kucatshangelwa ubunjalo obuhambisanayo be-solder, i-PCB nezinto zokupakisha kuqinisekisa ukusebenza nokuthembeka kwe-PCBA.
I-Zhejiang NeoDen Technology Co., LTD., eyasungulwa ngo-2010, ingumkhiqizi ochwepheshe okhethekile emshinini wokukhetha nendawo we-SMT, ihhavini eligeleza kabusha, umshini wokuphrinta we-stencil, ulayini wokukhiqiza we-SMT neminye Imikhiqizo ye-SMT.Sineqembu lethu le-R & D kanye nemboni yethu, sisebenzisa i-R&D yethu ecebile enokuhlangenwe nakho, ukukhiqizwa okuqeqeshwe kahle, sazuza idumela elihle kumakhasimende omhlaba wonke.
Kule minyaka eyishumi, sithuthukise ngokuzimela i-NeoDen4, i-NeoDen IN6, i-NeoDen K1830, i-NeoDen FP2636 kanye neminye imikhiqizo ye-SMT, eyathengiswa kahle emhlabeni wonke.Kuze kube manje, sesithengise imishini engaphezu kuka-10,000pcs futhi sayithumela emazweni angaphezu kuka-130 emhlabeni jikelele, sakha idumela elihle emakethe.Ku-Ecosystem yethu yomhlaba wonke, sibambisana nozakwethu ohamba phambili ukuze silethe isevisi yokuthengisa evala kakhudlwana, ukusekelwa okuphezulu okuchwepheshile nokusebenza kahle.
