Nubuhe bumenyi bwibanze bwo kwinjiza PCB?

Amategeko ya PCB:

1. Mubihe bisanzwe, ibice byose bigomba gutondekwa hejuru yubutaka bwumuzunguruko.Gusa iyo ibice byo hejuru bigize ubucucike burashobora kuba ibikoresho bimwe bifite uburebure buke hamwe nubushyuhe buke buke, nka chip résistants, chip capacitor, na Chip ICs bishyirwa kumurongo wo hasi.

2. Hashingiwe ku kwemeza imikorere y’amashanyarazi, ibice bigomba gushyirwa kuri gride hanyuma bigashyirwa hamwe bisa cyangwa bihagaritse kugirango bibe byiza kandi byiza.Muri rusange, ibice ntibyemewe guhuzagurika;ibice bigomba gutondekwa neza, nibigize bigomba gutondekwa kumurongo wose.Gukwirakwiza kimwe hamwe n'ubucucike buhoraho.

3. Umwanya muto uri hagati ya padiri yegeranye yibice bitandukanye kurubaho ruzunguruka bigomba kuba hejuru ya 1MM.

4. Intera kuva kumpande yumuzunguruko muri rusange ntabwo iri munsi ya 2MM.Imiterere myiza yikibaho cyumuzingi ni urukiramende rufite igipimo cya 3: 2 cyangwa 4: 3.Iyo ubunini bwumuzunguruko burenze 200MM kuri 150MM, ikibaho cyumuzunguruko gishobora kwihanganira imbaraga za Mechanical.

Ibitekerezo bya PCB

(1) Irinde gutondekanya imirongo yingenzi yibimenyetso kumpera ya PCB, nk'isaha no gusubiramo ibimenyetso.

(2) Intera iri hagati ya wire ya chassis nubutaka bwa signal nibura mm 4;gumana igipimo cya aspect ya wire ya chassis munsi ya 5: 1 kugirango ugabanye ingaruka za inductance.

(3) Koresha imikorere ya LOCK kugirango ufunge ibikoresho numurongo imyanya yagenwe, kugirango bitazakoreshwa nabi mugihe kizaza.

(4) Ubugari ntarengwa bwinsinga ntibugomba kuba munsi ya 0.2mm (8mil).Mubucucike bwinshi kandi busobanutse neza bwanditse bwumuzingi, ubugari nintera yinsinga muri rusange ni 12mil.

. ubugari bwumurongo hamwe numurongo utandukanijwe byombi ni 10mil, mugihe umugozi umwe gusa unyuze hagati yipine zombi, diameter ya padi irashobora gushirwa kuri 64mil, naho ubugari bwumurongo hamwe numurongo wumurongo byombi ni 12mil.

.Ibigize byoroshye kwivanga ntibishobora kuba hafi yundi, kandi ibyinjira nibisohoka bigomba kubikwa kure hashoboka.
