Nibihe bisabwa muburyo bukenewe kubibaho byumuzunguruko wa PCB?

1. Ingano ya PCB
Ibisobanuro by'ibanze】 Ingano yaPCBbigarukira kubushobozi bwibikoresho byo gutunganya ibikoresho bya elegitoroniki.Kubwibyo, ingano ya PCB igomba kwitabwaho mugushushanya ibicuruzwa bya sisitemu.

(3) Kuri PCBs ntoya, igomba gutegurwa nkigikorwa cyo kuzamura umusaruro wumurongo wose wibyakozwe.
Requirements Ibishushanyo mbonera】
(1) Muri rusange, ubunini ntarengwa bwa PCB bugomba kuba bugarukira kuri 460mm × 610mm.
(2) Ingano isabwa ni (200 ~ 250) mm × (250 ~ 350) mm, naho igipimo kigomba kuba <2.
(3) Kuri PCB ifite ubunini bwa "125mm × 125mm", igomba gukorwa mubunini bukwiye.

Imiterere ya PCB
[Amavu n'amavuko Ibisobanuro] Ibikoresho bitanga umusaruro SMT ikoresha inzira ziyobora mu gutwara PCB, na PCB zifite imiterere idasanzwe ntishobora gutwarwa, cyane cyane PCB zifite uduce ku mfuruka.
Requirements Ibishushanyo mbonera】
(1) Imiterere ya PCB igomba kuba kare kare ifite impande enye.
.Ikarita yo hagati.
(3) Kubibaho byiza bya SMT, icyuho kiremewe, ariko ingano yicyuho igomba kuba munsi ya kimwe cya gatatu cyuburebure bwuruhande.Kubarenze ibi bisabwa, uruhande rwo gushushanya rugomba kuzuzwa.

3. Uruhande rwohereza
[Amavu n'amavuko Ibisobanuro] Ingano yuruhererekane ruterwa nibisabwa na gari ya moshi iyobora ibikoresho.Kumashini zicapura, imashini zishira hamwe no kwerekana itanura ryo kugurisha, impande zitanga muri rusange zisabwa kurenza 3.5mm.
Requirements Ibishushanyo mbonera】
.kubishyirwaho, icyerekezo kirekire cyerekezo nacyo kigomba gukoreshwa nkicyerekezo cyohereza.
(2) Mubisanzwe, impande zombi za PCB cyangwa icyerekezo cyo kohereza zikoreshwa nkuruhande rwohereza.Ubugari ntarengwa bwuruhande rwohereza ni 5.0mm.Ntabwo hagomba kubaho ibice cyangwa kugurisha hamwe imbere ninyuma kuruhande rwohereza.

4. Umwobo
[Ibisobanuro by’ibanze] Inzira nyinshi nko gutunganya, guteranya, no kugerageza bisaba guhagarara neza kwa PCB.Kubwibyo, imyenge ihagaze muri rusange isabwa gushushanywa.
Requirements Ibishushanyo mbonera】
.Iyambere ikoreshwa muguhagarara naho iyindi ikoreshwa mubuyobozi.
Nta kintu cyihariye gisabwa kuri aperture ihagaze, irashobora gushushanywa ukurikije ibisobanuro byuruganda rwawe, kandi ibipimo bisabwa ni 2,4mm na 3.0mm.
Umwobo uhagaze ugomba kuba umwobo.Niba PCB ari PCB yakubiswe, umwobo uhagaze ugomba kuba ufite plaque kugirango wongere ubukana.
Uburebure bw'umwobo uyobora ni inshuro ebyiri z'umurambararo.
Hagati yumwobo uhagaze hagomba kuba hejuru ya 5.0mm uvuye kuruhande rwihererekanyabubasha, kandi ibyobo byombi byerekana bigomba kuba kure hashoboka.Birasabwa kubitondekanya kuruhande rwa PCB.
. hepfo yinyuguti irashobora kandi gukoreshwa mugucomeka.

5. Ibimenyetso byerekana
[Ibisobanuro by’ibanze] Imashini zishyirwaho zigezweho, imashini zicapura, ibikoresho byo kugenzura optique (AOI), ibikoresho byo kugenzura ibicuruzwa byagurishijwe (SPI), nibindi byose bikoresha sisitemu yo guhitamo neza.Kubwibyo, ibimenyetso byerekana neza bigomba kuba byateguwe kuri PCB.

Fiducial).Iyambere ikoreshwa kumwanya wibibaho byose, naho iyakoreshejwe mugushira kumwanya wibibaho cyangwa ibice byiza.
.Mubisanzwe, birasabwa gushushanya umuzenguruko wumuringa usobanura Ø1.0m.Urebye itandukaniro riri hagati yibara ryibintu nibidukikije, ahantu hatagurishwa 1mm nini kuruta ikimenyetso cyerekana umwanya uhari, kandi nta nyuguti zemewe muriyo.Bitatu ku kibaho kimwe Kubaho cyangwa kubura umuringa wumuringa murwego rwimbere bigomba kuba bimwe munsi yikimenyetso.

(6) Niba hari ibice byashyizwe kumpande zombi, buri ruhande rugomba kugira ibimenyetso byerekana neza.
(7) Niba nta mwobo uhagaze kuri PCB, hagati yikimenyetso cyerekana optique igomba kuba irenga 6.5mm uvuye kuruhande rwa PCB.Niba hari umwobo uhagaze kuri PCB, hagati yikimenyetso cya optique yerekana umwanya ugomba kuba wateguwe kuruhande rwumwobo uhagaze hafi ya PCB.
