Inama 5 zingenzi za PCB zo gushushanya inama yinteko ya PCB
Mubikorwa byo guteranya PCB, tuzakenera imashini za SMT kugirango dushyire ibice kuri PCB.Ariko kubera ko buri PCB ingano, imiterere cyangwa ibice bitandukanye, kugirango uhuze neza nuburyo bwo guteranya SMT, kunoza imikorere no kugabanya ikiguzi cyiteraniro.Niyo mpamvuUruganda rukora inteko ya PCBbakeneye guhuza ibice bya PCB.PCBFuture iguha guildlines 5 kumurongo wa PCB kugirango inteko nziza ya PCB.
Inama 1: Ingano ya PCB
Ibisobanuro: Ingano ya PCB igarukira kubushobozi bwibikoresho byo gutunganya ibikoresho bya elegitoroniki.Kubwibyo, ingano ya PCB igomba kwitabwaho mugihe turimo gutegura ibisubizo byibicuruzwa.
.
(2) Ingano dusaba nuko ihuye nibikoresho byumurongo wubuyobozi bwa SMT PCB.Ni ingirakamaro ku musaruro wa buri bikoresho kandi bikuraho icyuho cyibikoresho.
.
Ibishushanyo mbonera:
(1) Mubisanzwe, ingano ntarengwa ya PCB igomba kugarukira kuri 460mm × 610mm.
(2) Ingano isabwa ingano ni (200 ~ 250) × (250 ~ 350) mm, naho igipimo kigomba kuba munsi ya 2.
(3) Kuri PCBs ifite ubunini buri munsi ya 125mm × 125mm, PCB igomba guterwa mubunini bukwiye.
Inama 2: Imiterere ya PCB
Ibisobanuro: Ibikoresho byo guteranya SMT bifashisha inzira yo kuyobora PCBs, kandi ntishobora kwimura PCBs zidasanzwe, cyane cyane PCB zifite icyuho mu mfuruka.
Ibishushanyo mbonera:
(1) Imiterere ya PCB igomba kuba kare kare ifite impande enye.
. hanyuma bigatera ikibaho guhuzagurika mugihe cyo kwimura.
(3) Ikibaho cyiza cya SMT cyemerewe kugira icyuho, ariko ingano yikinyuranyo igomba kuba munsi ya kimwe cya gatatu cyuburebure bwuruhande aho ruherereye.Kubatujuje ibi bisabwa, tugomba gukora uburebure bwibikorwa.
.
Inama 3: Ibikoresho bya PCB (imipaka ya PCB)
Ibisobanuro: Ingano yabatwara PCB kubisabwa bya gari ya moshi itanga ibikoresho.Nka: imashini zicapura, imashini zo gushyira hamwe no kwerekana itanura ryo kugurisha.Mubisanzwe basabwa kwerekana inkombe (Imipaka) hejuru ya 3.5mm.
Ibishushanyo mbonera:
.Kugabanya PCB, icyerekezo kirekire kuruhande nacyo kigomba gukoreshwa nkicyerekezo cyo kohereza.
(2) Mubisanzwe, impande zombi za PCB cyangwa kugabana icyerekezo cya PCB zikoreshwa nkuruhande rwohereza (imipaka ya PCB).Ubugari ntarengwa bwimbibi za PCB ni 5.0mm.Ntabwo hagomba kubaho ibice cyangwa kugurisha kugurisha imbere ninyuma kuruhande rwohereza.
(3) Kuruhande rutari rwohereza, ntakabuza muriInteko ya SMT PCBibikoresho, ariko nibyiza kubika igice cya 2.5mm cyibice bibujijwe.
Inama 4: Umwobo
Ibisobanuro: Inzira nyinshi nko gukora PCB, guteranya PCB, no kugerageza bisaba guhagarara neza kwa PCB.Kubwibyo, birasabwa muri rusange gushushanya ibyobo.
Ibishushanyo mbonera:
.
Nta kintu cyihariye gisabwa kuri aperture ihagaze, irashobora gushushanywa ukurikije ibisobanuro byuruganda rwawe.Diameter isabwa ni 2,4mm na 3.0mm.
Kubona ibyobo bigomba kuba bidafite ubutare.Niba PCB ari PCB yuzuye, isahani yumwobo igomba kuba yarateguwe kugirango umwobo uhagarare kugirango wongere ubukana.
Uburebure bw'umwobo uyobora ni inshuro 2 z'umurambararo.
Hagati yumwobo uhagaze hagomba kuba hejuru ya mm 5.0 uvuye kuruhande rwihererekanyabubasha, naho ibyobo byombi bigomba kuba kure hashoboka.Birasabwa kubishyira kuri diagonal ya PCB.
.Muri ubu buryo, igishushanyo mbonera gishobora kugera ku mikoreshereze rusange yimpande zombi.Kurugero, screw hepfo yinyuguti irashobora kandi gukoreshwa mugucomeka.
Inama 5: Guhitamo fiducial
Ibisobanuro: Umusozi ugezweho, printer, AOI na SPI byose bifata sisitemu yo guhitamo.Kubwibyo, optique yimyanya fiducial igomba kuba yarateguwe kubuyobozi bwa PCB.
Ibishushanyo mbonera:
Umwanya wa fiducial ugabanijwemo kwizerwa kwisi yose hamwe na fiducial yaho.Iyambere ikoreshwa kumwanya wose uhagaze, naho iyanyuma ikoreshwa muguhuza ikibaho cyumukobwa cyangwa ibice byiza.
.Mubisanzwe, birasabwa gukora igishushanyo cya 1.0m kizengurutse umuringa.Harebwa itandukaniro riri hagati yamabara yibidukikije hamwe nibidukikije, ahantu ho gusudira kutarwanya mm 1 kurenza ubunini bwa optique ya fiducial igomba kubikwa.Ntabwo inyuguti zemewe mukarere.Niba hari umuringa wumuringa murwego rwimbere munsi yibimenyetso bitatu kumurongo umwe ugomba kuba umwe.
. .
.
.
(6) Niba hari ibice byo gushiraho kumpande zombi, hagomba kuba optique ihagaze neza kuri buri ruhande.
.Niba hari umwobo uhagaze kuri PCB, hagati ya optique ya optique ya fiducial igomba gushushanywa kuruhande rwumwobo uhagaze hafi yikigo cya PCB.
PCBFuture irashobora gutanga hamweTurnkey PCB intekoserivisi zirimo Ibihimbano bya PCB, abaturage ba PCB, Ibigize isoko no kugerageza.Ba injeniyeri bacu bazafasha abakiriya bacu gutondekanya imbaho mbere yumusaruro wa PCB, hanyuma nyuma yo kurangiza ikizamini, tuzafasha kumena buri gice no kohereza kubakiriya bacu.Niba ufite ikibazo kijyanye nigishushanyo cya PCB, wumve neza.Turashobora kuguha inkunga ya tekiniki yubuntu.
