Ibibazo bigomba kwitabwaho mugihe ucomeka ibiceInteko ya PCBinzira

Ibigize PCB bigomba gutoranywa neza mbere yo kuzuza ibisabwa byumuzunguruko.Twabibutsa ko ibyiyumvo bya voltage yumubare wibice bifite imikorere imwe, icyitegererezo hamwe nabatanga ibintu bitandukanye bashobora kugira itandukaniro rinini.None, ni ibihe bibazo dukwiye kwitondera mugihe dushyiramo ibice muri PCB?

1. Kugabanya ibyasohotse kugirango wirinde gufunga umuzunguruko wa CMOS

Gufunga-muburyo nuburyo budasanzwe bwo kunanirwa kumuzunguruko wa CMOS, kubera ko hariho transistor ya parasitike PNP na transistor ya NPN mumiterere yimbere yumuzunguruko wa CMOS, kandi bakora parasitike PNPN thyristor, bityo rero gufunga-ingaruka zumuzunguruko wa CMOS ni nanone bita "ingaruka ya thyristor".

2. Gukoresha imiyoboro ya filteri

Rimwe na rimwe, umugozi muremure winjira urakenewe hagati ya sisitemu yumuzunguruko wa CMOS hamwe nubukanishi, ibyo bikaba byongera amahirwe yo guhuza amashanyarazi.Noneho, muyunguruzi urusobe rugomba gusuzumwa.

3. Umuyoboro wa RC

Iyo bishoboka, kubwinjiza bworoshye bwibikoresho bya bipolar, umuyoboro wa RC ugizwe na résistoriste hamwe na capacitori byibura 100pF irashobora kugabanya ingaruka ziterwa na electrostatike.

4. Kwirinda pin yinjiza ya CMOS irahagarikwa.

Irinde ko iherezo ryibikoresho bya CMOS bigurishwa ku kibaho cyumuzunguruko bihagarikwa.Mugihe kimwe, bigomba kwitondera ibyinjijwe byose bitari ngombwa biganisha kubikoresho bya CMOS ntibyemewe guhagarikwa.Kuberako ibyinjijwe bimaze guhagarikwa, ubushobozi bwo kwinjiza buzaba bumeze nabi.

Ibyavuzwe haruguru nincamake yibibazo bigomba kwitabwaho mugikorwa cyo kwinjiza ibice muri PCB.Nizere ko bizagufasha.Kubindi bisobanuro, nyamuneka sura urubuga rwacu www.pcbfuture.com
