Izeluleko ezi-5 ezibalulekile zephaneli ye-PCB ye-PCB Assembly

Enqubeni yokuhlanganisa i-PCB, sizodinga imishini ye-SMT ukuze inamathisele izingxenye ku-PCB.Kodwa njengoba usayizi we-PCB ngayinye, umumo noma izingxenye zihlukile, ukuze uzivumelanise kangcono nenqubo yokuhlanganisa ye-SMT, uthuthukise ukusebenza kahle futhi unciphise izindleko zokuhlanganisa.Yingakho keUmkhiqizi womhlangano we-PCBisidingo sokumisa ipaneli ye-PCB.I-PCBFuture ikunikeza imigqa emi-5 yephaneli ye-PCB yakho yokuhlanganisa okungcono kwe-PCB.

Amathiphu 1: Usayizi we-PCB

Incazelo: Usayizi we-PCB unqunyelwe amandla emishini yomugqa wokukhiqiza wokucubungula nge-elekthronikhi.Ngakho-ke, ubukhulu be-PCB kufanele bucatshangelwe uma siklama izixazululo zomkhiqizo.

(1) Ubukhulu besayizi ye-PCB engafakwa kumshini wokuhlanganisa we-SMT PCB buncike kusayizi ojwayelekile we-PCB, usayizi omningi ngu-20″×24″, okuwububanzi besitimela ngu-508mm×610mm.

(2) Usayizi esiwuncomayo ukuthi ufana nezisetshenziswa zolayini webhodi le-SMT PCB.Kunenzuzo ekusebenzeni kahle kokukhiqiza kwemishini ngayinye futhi kuqeda ibhodlela lemishini.

(3) Kuma-PCB anosayizi omncane, kufanele sakhelwe njengebhodi lokuhlanganisa ukuze sithuthukise ukusebenza kahle kokukhiqiza kwawo wonke umugqa wokukhiqiza.

Izidingo zokuklama:

(1) Ngokuvamile, ubukhulu bobukhulu be-PCB kufanele bukhawulelwe kububanzi obungu-460mm×610mm.

(2) Ububanzi obunconywayo bukasayizi (200~250) × (250~350) mm, futhi ukubukeka kwesilinganiselo kufanele kube ngaphansi kuka-2.

(3) Kuma-PCB anosayizi ongaphansi kuka-125mm×125mm, i-PCB kufanele ihlanganiswe ibe usayizi ofanele.

Amathiphu 2: Ukuma kwe-PCB

Incazelo: Imishini yokuhlanganisa ye-SMT isebenzisa amalayili angumhlahlandlela ukuze idlulise ama-PCB, futhi ayikwazi ukudlulisa ama-PCB anomumo ongajwayelekile, ikakhulukazi ama-PCB anezikhala emakhoneni.

Izidingo zokuklama:

(1) Ukuma kwe-PCB kufanele kube isikwele esivamile esinamakhona ayindilinga.

(2) Ukuze kuqinisekiswe ukuzinza kwenqubo yokudlulisela, i-PCB emise ngendlela engavamile kufanele ithathwe ngokuthi iguqulwe ibe isikwele esijwayelekile ngokuhlanganisa, ikakhulukazi izikhala zekhoneni kufanele zigcwaliswe ukuze kugwenywe ukuthi i-wave soldering ibanjwe imihlathi. bese kubangela ukuthi ibhodi ligcwale ngesikhathi sokudlulisa.

(3) Ibhodi le-SMT elimsulwa livunyelwe ukuthi libe nezikhala, kodwa usayizi wegebe kufanele ube ngaphansi kwengxenye eyodwa kwezintathu yobude bohlangothi lapho itholakala khona.Kulabo abangahlangabezani nale mfuneko, kufanele senze ubude benqubo yokuklama.

(4) Ngaphezu komklamo ohehayo womunwe wegolide, imiphetho ezinhlangothini zombili zokufaka kufanele futhi i-chamfer (1~1.5) × 45° ukuze kube lula ukufakwa.

Amathiphu 3: Izinti ze-PCB zamathuluzi (imingcele ye-PCB)

Incazelo: Usayizi wabagibeli be-PCB ezidingweni zokuthutha ujantshi wemishini.Okufana nalokhu: imishini yokunyathelisa, imishini yokubeka kanye nezithando zokushisa zokugeleza kabusha.Ngokuvamile zidingeka ukuthi zidlulisele unqenqema (Umngcele) ngaphezu kuka-3.5mm.

Izidingo zokuklama:

(1) Ukuze kuncishiswe ukuwohloka kwe-PCB ngesikhathi sokudayiswa, isiqondiso esiseceleni eside se-PCB engabekwanga ngokuvamile sisetshenziswa njengendlela yokudlulisela.Futhi i-PCB ye-splice, isiqondiso esiseceleni eside kufanele futhi sisetshenziswe njengendlela yokudlulisela.

(2) Ngokuvamile, izinhlangothi ezimbili ze-PCB noma i-splice PCB yokudlulisela isiqondiso zisetshenziswa njengohlangothi lokudlulisela (imingcele ye-PCB).Ububanzi obuncane bemingcele ye-PCB bungu-5.0mm.Akufanele kube khona izingxenye noma amajoyinti e-solder ngaphambili nangemuva ohlangothini lokudlulisela.

(3) Ohlangothini olungadluliseli, akukho mkhawulo kuUmhlangano we-SMT PCBimishini, kodwa kungcono ukubekisa ingxenye engu-2.5mm indawo engavunyelwe.

Amathiphu 4: Imbobo yokubeka

Incazelo: Izinqubo eziningi ezifana nokukhiqizwa kwe-PCB, ukuhlanganiswa kwe-PCB, nokuhlola kudinga ukuma okunembile kwe-PCB.Ngakho-ke, ngokuvamile kuyadingeka ukuklama izimbobo zokubeka.

Izidingo zokuklama:

(1)Ku-PCB ngayinye, kufanele kuklanywe okungenani izimbobo zokubeka ezimbili, eyodwa iyindingilizi kanti enye iyisimo se-groove ende, eyokuqala isetshenziselwa ukubeka indawo bese eyakamuva isetshenziselwa ukuqondisa.

Asikho isidingo esikhethekile sembobo yokuma, ingaklanywa ngokuya ngemininingwane yefekthri yakho.Ububanzi obunconywayo bungu-2.4mm no-3.0mm.

Izimbobo zokuthola indawo akufanele zenziwe ngensimbi.Uma i-PCB iyi-PCB engenalutho, ipuleti lembobo kufanele lidizayinelwe ukubeka imbobo ukuze kuthuthukiswe ubulukhuni.

Ubude bembobo yomhlahlandlela ngokuvamile izikhathi ezi-2 zobubanzi.

Isikhungo sembobo yokuma kufanele sibe ngaphezu kuka-5.0 mm ukusuka ohlangothini lokudlulisela, futhi izimbobo zokubeka ezimbili kufanele zibe kude ngangokunokwenzeka.Kunconywa ukuthi uwabeke ku-diagonal ye-PCB.

(2)Ku-PCB exubile (i-PCBA enamapulagi afakiwe), indawo yezimbobo zokubeka kufanele ihambisane.Ngale ndlela, ukwakheka kwamathuluzi kungafinyelela ukusetshenziswa okuvamile kwezinhlangothi zombili.Isibonelo, ubakaki ongezansi oyisikulufa ungaphinda usetshenziselwe ithreyi ye-plug-in.

Amathiphu 5: Ukubeka i-fiducial

Incazelo: I-mounter yesimanje, iphrinta, i-AOI ne-SPI zonke zisebenzisa isistimu yokuma yokubona.Ngakho-ke, i-optical positioning fiducial kumele yakhelwe ebhodini le-PCB.

Izidingo zokuklama:

I-Positioning fiducial ihlukaniswe yaba yi-fiducial yomhlaba kanye neyendawo.Eyangaphambili isetshenziselwa ukuma kwebhodi lonke, kanti lena yakamuva isetshenziselwa ukubeka ibhodi lendodakazi ye-patchwork noma izingxenye ezinhle zokuhlukanisa izikhala.

(2) I-fiducial ye-optical positioning ingaklanywa njengesikwele, isiyingi sedayimane, isiphambano futhi kahle enobude obungu-2.0 mm.Ngokuvamile, kunconywa ukuklama isibalo sencazelo yethusi esiyindilinga esingu-1.0m.Kubhekwa umehluko phakathi kombala wezinto ezibonakalayo nendawo ezungezile, indawo yokushisela engamelani engu-1 mm enkulu kune-fiducial yokuma okubonakalayo kufanele igcinwe.Azikho izinhlamvu ezivunyelwe endaweni.Ukuthi kukhona ucwecwe lwethusi kungqimba olungaphakathi ngaphansi kwezimpawu ezintathu endaweni eyodwa yebhodi kufanele kuhambisane.

(3) Endaweni ye-PCB enezingxenye ze-SMD, kuphakanyiswa ukuthi kubekwe i-fiducial ye-optical positioning ekhoneni lebhodi, ukuze kumiswe i-PCB stereoscopically (amaphuzu amathathu anquma indiza, engathola ukushuba kokunamathisela kwe-solder) .

(4) Ngokungeziwe ku-fiducial ye-optical positioning yepuleti lonke, kungcono ukudizayina i-fiducial ye-optical positioning ezimbili noma ezintathu emakhoneni epuleti ngalinye leyunithi.

(5) Ku-QFP enebanga eliphakathi nendawo eliholayo elingaphansi noma elilingana no-0.5 mm kanye ne-BGA enebanga eliphakathi nendawo eliholayo elingaphansi noma elilingana no-0.8 mm, i-fiducial yokuma kwendawo yokubona kufanele imiswe emakhoneni aphambene ukuze ibekwe endaweni efanele.

(6) Uma kunezingxenye zokukhweza nhlangothi zombili, kufanele kube ne-optical positioning fiducial ohlangothini ngalunye.

(7) Uma ingekho imbobo yokuma ku-PCB, indawo emaphakathi ye-optical positioning fiducial kufanele ibe ngaphezu kuka-6.5mm kude nomkhawulo wokudlulisa webhodi lesekethe.Uma kunembobo yokuma ku-PCB, isikhungo se-optical positioning fiducial kufanele sidizayinwe eceleni kwembobo yokuma eduze nendawo emaphakathi yebhodi le-PCB.

I-PCBFuture ingahlinzeka ngeUmhlangano we-Turnkey PCBisevisi ehlanganisa i-PCB Fabrication, inani labantu be-PCB, ukutholakala kwe-Components kanye nokuhlolwa.Onjiniyela bethu bazosiza ikhasimende lethu ukuthi lifake amabhodi amabhodi ngaphambi kokukhiqizwa kwe-PCB, bese kuthi ngemva kokuphothula ukuhlolwa, sizosiza ukugqekeza ucezu ngalunye bese sithumela kumakhasimende ethu.Uma unemibuzo mayelana ne-PCB design, zizwe ukhululekile ukuxhumana nathi.Singakunikeza usekelo lwamahhala lobuchwepheshe.
