Iimveliso
Ibhodi yeTelecom yeSelfowuni idibanisa imveliso
Le yiprojekthi yokudityaniswa kwe-PCB ye-cellphone main baord.Ii-electronics zabathengi, ukusuka kwiimveliso ezivakalayo ukuya kwizinto ezinxitywayo, imidlalo okanye nenyani eyinyani, zonke ziya ziqhagamshelwa ngakumbi.Ihlabathi ledijithali esiphila kulo lifuna umgangatho ophezulu woqhagamshelwano kunye ne-electronics ephezulu kunye nezakhono, nakwimveliso elula kakhulu, exhobisa abasebenzisi kwihlabathi jikelele. Njengenkampani yeemoto zombane kunye nomvelisi we-PCBA weemoto, thina, e-ANKE, sinikezela ngeenkonzo ezisemgangathweni ophezulu ubunjineli, uyilo kunye neprototyping.

Inkqubo yeNdibano yeSMT
1. Indawo (ukunyanga)
Indima yayo kukunyibilikisa isiziba seglu ukwenzela ukuba amacandelo entaba yomphezulu kunye nebhodi yePCB idityaniswe ngokuqinileyo kunye.
Isixhobo esisetyenzisiweyo yi-oven yokunyanga, ebekwe emva komatshini wokubeka kumgca we-SMT.
2. Ukuthengiswa kwakhona
Indima yayo kukunyibilikisa i-solder paste, ukwenzela ukuba iindawo zokunyuka komphezulu kunye nebhodi ye-PCB ziboshwe ngokuqinileyo kunye.Isixhobo esisetyenzisiweyo yayiyi-oven yokubuyisela, ebekwe emva kweepads.
Mounter kumgca wemveliso we-SMT.
3. Ukucoca indibano ye-SMT
Into eyenzayo kukukhupha iintsalela ze-solder ezifana ne-ux
I-PCB edityanisiweyo iyingozi kumzimba womntu.Isixhobo esisetyenzisiweyo ngumatshini wokuhlamba, indawo ingaba
Ayilungiswanga, isenokuba kwi-intanethi okanye ngaphandle kweintanethi.
4. Ukuhlolwa kwendibano ye-SMT
Umsebenzi wayo kukujonga umgangatho we-welding kunye nomgangatho wendibano
Ibhodi yePCB edityanisiweyo.
Izixhobo ezisetyenzisiweyo ziquka i-glass magnifying, i-microscope, i-in-circuit tester (ICT), i-need tester, i-automatic optical inspection (AOI), inkqubo yokuhlola i-X-RAY, umhloli osebenzayo, njl.
5. Ukusebenza kwakhona kwendibano ye-SMT
Indima yayo kukuphinda kusetyenzwe kwakhona ibhodi yePCB ayiphumelelanga
Impazamo.Izixhobo ezisetyenzisiweyo ziyi-soldering iron, i-rework station, njl.
naphi na kumgca wemveliso.Njengoko usazi, kukho imiba emincinci ngexesha lemveliso, ngoko ke ukuhlangana kwakhona kwezandla yeyona ndlela ilungileyo.
6. Ukupakishwa kwendibano ye-SMT
I-PCBMay ibonelela ngendibano, ukupakishwa kwesiko, ukuleyibheli, imveliso yegumbi elicocekileyo, ulawulo lokuvala inzala kunye nezinye izisombululo ukunika isisombululo esipheleleyo semfuno zenkampani yakho.
Ngokusebenzisa i-automation ukudibanisa, ukupakisha kunye nokuqinisekisa iimveliso zethu, sinokunika abathengi bethu inkqubo yokuvelisa ethembekileyo nesebenzayo.
Umboneleli wenkonzo yokwenziwa kombane kwiZithuthi, sigubungela izicelo ezininzi:
> Imveliso yekhamera yeemoto
> Izibonisi zobushushu kunye nokufuma
> Isibane sentloko
> Ukukhanyisa ngobuchule
> Iimodyuli zamandla
> Izilawuli zeengcango & neziphatho zocango
> Iimodyuli zolawulo lomzimba
> Ulawulo lwamandla
Okwesithathu, amaxabiso ahluke ngenxa yobunzima kunye nokuxinana.
PCB iya kuba iindleko ezahlukeneyo nokuba izixhobo kunye nenkqubo ziyafana, kodwa kunye nobunzima ezahlukeneyo kunye noxinaniso.Ngokomzekelo, ukuba kukho imingxuma eyi-1000 kwiibhodi zombini zeesekethe, ububanzi bomngxuma webhodi enye bukhulu kuno-0.6mm kunye nobubanzi bomngxuma welinye ibhodi bungaphantsi kwe-0.6mm, okuya kwenza iindleko ezahlukeneyo zokomba.Ukuba iibhodi zeesekethe ezimbini ziyafana kwezinye izicelo, kodwa ububanzi bomgca buhluke kwakhona kubangela iindleko ezahlukeneyo, ezifana nobubanzi bebhodi enye bukhulu kune-0.2mm, ngelixa enye ingaphantsi kwe-0.2mm.Ngenxa yokuba iibhodi ububanzi ngaphantsi kwe-0.2mm zinezinga eliphezulu elineziphene, oku kuthetha ukuba ixabiso lemveliso liphezulu kunesiqhelo.
Okwesine, amaxabiso ahluka ngenxa yeemfuno ezahlukeneyo zabathengi.
Iimfuno zabathengi ziya kuchaphazela ngokuthe ngqo izinga elingenasiphako kwimveliso.Okufana nebhodi enye izivumelwano IPC-A-600E class1 ifuna 98% izinga lokupasa, ngelixa ngokuvumelana class3 kufuna kuphela 90% ireyithi yokupasa, okubangela iindleko ezahlukeneyo kumzi-mveliso kwaye ekugqibeleni kukhokelele utshintsho kumaxabiso emveliso.
