Iingcebiso ezi-5 ezibalulekileyo zoyilo lwepaneli yePCB yeNdibano yePCB

Kwinkqubo yendibano ye-PCB, siya kufuna oomatshini be-SMT ukuze bancamathisele amalungu kwi-PCB.Kodwa ekubeni ubungakanani bePCB nganye, imilo okanye amacandelo ahlukile, ukuze ulungelelanise ngcono inkqubo yokuhlanganisa i-SMT, ukuphucula ukusebenza kakuhle nokunciphisa iindleko zokuhlanganisa.Kunjalo ngobaPCB indibano umenziidinga ukubeka emgangathweni ulungelelwaniso lwePCB.I-PCBFuture ikubonelela ngee-guildlines ezi-5 zepaneli ye-PCB yakho yendibano engcono ye-PCB.

Iingcebiso 1: Ubungakanani bePCB

Inkcazo: Ubungakanani bePCB bukhawulelwe ngamakhono ezixhobo zomgca wokuvelisa ngombane.Ke ngoko, ubungakanani bePCB kufuneka buthathelwe ingqalelo xa siyila izisombululo zemveliso.

(1) Ubukhulu besayizi ye-PCB enokuthi ifakwe kwi-SMT PCB isixhobo sokuhlanganisa ixhomekeke kubungakanani obuqhelekileyo be-PCB, ubukhulu besayizi yi-20 ″ × 24 ″, oko kukuthi ububanzi kaloliwe yi-508mm×610mm.

(2) Ubungakanani esibucebisayo buhambelana nesixhobo somgca webhodi ye-SMT PCB.Kunenzuzo ekusebenzeni kakuhle kwemveliso yesixhobo ngasinye kunye nokuphelisa ibhotile yezixhobo.

(3) KwiiPCB ezinobungakanani obuncinci, kufuneka siyilwe njengebhodi yokudibanisa ukuze kuphuculwe ukusebenza kakuhle kwemveliso yomgca wonke wemveliso.

Iimfuno zoyilo:

(1) Ngokuqhelekileyo, ubukhulu besayizi ye-PCB kufuneka bukhawulelwe kuluhlu lwe-460mm×610mm.

(2) Uluhlu lobungakanani obucetyiswayo (200 ~ 250) × (250 ~ 350) mm, kwaye umlinganiselo wokulinganisa kufuneka ube ngaphantsi kwe-2.

(3) KwiiPCB ezinobungakanani obungaphantsi kwe-125mm×125mm, iPCB kufuneka idityaniswe kubungakanani obufanelekileyo.

Iingcebiso 2: Imilo yePCB

inkcazelo: Izixhobo zokuhlanganisa ze-SMT zisebenzisa ii-rails zesikhokelo ukudlulisa ii-PCB, kwaye azikwazi ukudlulisa ii-PCB ezinokwakheka okungaqhelekanga, ngakumbi ii-PCB ezinezikhewu ezikoneni.

Iimfuno zoyilo:

(1) Imilo yePCB kufuneka ibe sisikwere esiqhelekileyo esineekona ezingqukuva.

(2) Ukuze kuqinisekiswe uzinzo lwenkqubo yothumelo, i-PCB enemilo engaqhelekanga kufuneka ithathelwe ingqalelo ukuba iguqulelwe kwisikwere esisemgangathweni ngokudibanisa, ngakumbi izithuba zembombo kufuneka zizaliswe ukuze kuthintelwe ukuba i-soldering wave ibambeke ngemihlathi. kwaye emva koko ibangele ukuba ibhodi ixinge ngexesha lokudluliselwa.

(3) Ibhodi ye-SMT ecocekileyo ivumelekile ukuba ibe nezithuba, kodwa ubungakanani besithuba kufuneka bube ngaphantsi kwesinye kwisithathu sobude becala apho ikhoyo.Kwabo bangayifezekisiyo le mfuneko, kufuneka senze ubude benkqubo yoyilo.

(4) Ukongeza kwidizayini yoyilo lomnwe wegolide, imiphetho emacaleni omabini ofakelo nayo kufuneka ikhutshelwe (1~1.5) × 45° ukwenza kube lula ukufaka.

Iingcebiso 3: Izixhobo zePCB zezixhobo (imida yePCB)

Inkcazo: Ubungakanani bebhodi yePCB kwiimfuno zokuthutha umzila wezixhobo.Ezinje: oomatshini bokushicilela, oomatshini bokubeka kunye neendawo zokuthambisa zokuphinda ziphinde zifakwe.Ngokuqhelekileyo zifunwa ukuba zigqithise umda (umda) ngaphezu kwe-3.5mm.

Iimfuno zoyilo:

(1) Ukuze kuncitshiswe ukuguqulwa kwe-PCB ngexesha le-soldering, i-side side side ye-PCB engabekwanga isetyenziswa ngokubanzi njengesikhokelo sothumelo.Kwaye i-splice PCB, icala elide kufuneka lisetyenziswe njengesikhokelo sothumelo.

(2) Ngokuqhelekileyo, amacala amabini e-PCB okanye i-splice yokuhambisa i-PCB isetyenziswa njengecala lothumelo (imida ye-PCB).Ubuncinci ububanzi bemida yePCB yi-5.0mm.Akufunekanga kubekho iinxalenye okanye ii-solder joints ngaphambili nangasemva kwicala lothumelo.

(3) Kwicala elingadluliseli, akukho mda kwiIndibano ye-SMT PCBizixhobo, kodwa kungcono ukugcina icandelo 2.5mm indawo engavumelekanga.

Amacebiso 4: Ukubeka umngxuma

Inkcazo: Iinkqubo ezininzi ezifana nokuveliswa kwe-PCB, indibano ye-PCB, kunye novavanyo lufuna ukubekwa okuchanekileyo kwe-PCB.Ke ngoko, kuyafuneka ngokubanzi ukuyila imingxunya yokubeka.

Iimfuno zoyilo:

(1)Kwi-PCB nganye, ubuncinci imingxuma emibini yokumisa kufuneka iyilwe, enye ibe setyhula kwaye enye ibe yimilo yegroove ende, eyokuqala isetyenziselwa ukubeka kwaye le yokugqibela isetyenziselwa ukukhokela.

Akukho mfuneko ikhethekileyo kwindawo yokubeka indawo, inokuyilwa ngokweenkcukacha zomzi-mveliso wakho.Ububanzi obucetyiswayo yi-2.4mm kunye ne-3.0mm.

Imingxuma yokubeka indawo ayinakwenziwa isinyithi.Ukuba i-PCB yi-PCB engenanto, ipleyiti yomngxuma kufuneka ilungiselelwe ukubeka umngxuma ukunyusa ubulukhuni.

Ubude bomngxuma wesikhokelo ngokuqhelekileyo ngamaxesha angama-2 ububanzi.

Umbindi womngxuma wokumisa kufuneka ube ngaphezu kwe-5.0 mm ukusuka kwicala lokuhambisa, kwaye imingxuma emibini yokumisa kufuneka ibe kude kangangoko kunokwenzeka.Kuyacetyiswa ukuba uzibeke kwi-diagonal ye-PCB.

(2) Kwi-PCB edibeneyo (i-PCBA ene-plug-ins efakwe), indawo yemingxuma yokumisa kufuneka ihambelane.Ngale ndlela, ukuyilwa kwezixhobo kunokufezekisa ukusetyenziswa okuqhelekileyo kwamacala omabini.Umzekelo, isibiyeli esisezantsi sesikrufu singasetyenziselwa iplagi yetreyi.

Amacebiso 5: Ukubeka kwindawo ethembekileyo

Inkcazo: Isixhosi sangoku, umshicileli, i-AOI kunye ne-SPI zonke zamkela inkqubo yokubeka i-optical positioning.Ke ngoko, i-optical positioning fiducial kufuneka iyilwe kwibhodi yePCB.

Iimfuno zoyilo:

I-Positioning fiducial yahlulwe yaba yifiducial yehlabathi kunye neyengingqi.Eyangaphambili isetyenziselwa ukubekwa kwebhodi yonke, kwaye le yokugqibela isetyenziselwa ukubekwa kwebhodi yeentombi ze-patchwork okanye i-fice components.

2Ngokuqhelekileyo, kucetyiswa ukuba uyile umzobo wenkcazo yobhedu ojikelezayo we-1.0m.Kuqwalaselwa umahluko phakathi kombala wezinto ezibonakalayo kunye nokusingqongileyo, indawo ye-welding enganyangekiyo i-1 mm enkulu kune-fiducial yokubeka i-optical kufuneka igcinwe.Akukho zimpawu zivumelekileyo kwindawo.Ingaba kukho ifoyile yobhedu kuluhlu lwangaphakathi phantsi kweesimboli ezintathu kumphezulu webhodi enye kufuneka ihambelane.

(3) Kumphezulu we-PCB onamalungu e-SMD, kuyacetyiswa ukuba kubekwe i-fiducial yokubeka izinto ezintathu kwikona yebhodi, ukuze kubekwe i-PCB stereoscopically (amanqaku amathathu amisela inqwelomoya, enokubona ubukhulu be-solder paste) .

(4) Ukongeza kwi-fiducial ye-optical positioning yepleyiti yonke, kungcono ukuyila ezimbini okanye ezintathu zokubeka i-fiducial kwiikona zeyunithi yepleyiti nganye.

(5) Kwi-QFP eneziko elikhokelayo lomgama ongaphantsi okanye olingana no-0.5 mm kunye ne-BGA enomgama oseziko elikhokelayo ngaphantsi okanye olingana ne-0.8 mm, i-fiducial yendawo yokubona yokukhanya kufuneka imiselwe kwiikona ezichaseneyo ukuze kumiswe ngokuchanekileyo.

(6) Ukuba kukho izinto zokuxhoma kumacala omabini, kufuneka kubekho i-optical positioning fiducial kwicala ngalinye.

(7) Ukuba akukho mngxuma wokumisa kwi-PCB, iziko le-fiducial yokubeka i-optical kufuneka libe ngaphezu kwe-6.5mm kude nomda wothumelo webhodi yesekethe.Ukuba kukho umngxuma wokumisa kwi-PCB, umbindi we-fiducial ye-optical positioning kufuneka uyilwe kwicala lomngxuma wokumisa kufutshane nombindi webhodi ye-PCB.
