Kodi pali njira zingati zoyesera za PCB electromagnetic components?

Kuyesa magawo amagetsi a PCB ndi gawo lofunikira pakuyesa kwa PCB. Ndiye, ndi njira zingati zoyesera zomwe zilipo pazigawo za PCB electromagnetic?

1.Mayeso a coil wamba

Pakuyesa koyilo, mlatho wa digito ungagwiritsidwe ntchito kuyesa inductance pa intaneti. Chifukwa cha kuchuluka kwa magwiridwe antchitocoil inductornthawi zambiri sichitsika, inductance imatha kuyesedwa pafupipafupi kuposa 10kHz.

2. Kuyesa kwa koyilo ya Transformer

Poyesa mtengo wa inductance D wa koyilo yayikulu ya thiransifoma, titha kudziwa ngatithiransifomaali ndi inter-turn short circuit. Njira yeniyeni ndi: ikani mlatho wa digito kukhala 0.3V kapena pansipa, 10kHz kapena pamwamba, ndikuyesa mtengo wa D wa inductance yayikulu. Ngati mtengo wa D ndi waukulu kuposa 0.1, umaweruzidwa kuti thiransifoma yawonongeka ndipo sichingagwiritsidwe ntchito.

3. Kuzindikira zida za Nyumba

Masensa a Hall amapezeka mumagetsi amodzi komanso magetsi apawiri, komanso mtundu waposachedwa komanso mtundu wamagetsi otulutsa. Sensa imodzi yokha yamagetsi sichizindikira zomwe zilipo, ndipo chizindikirocho chimakhala ndi 1/2 yamagetsi amodzi. Ngati panopa ndi 0, kutulutsa kwa chizindikiro kumapatuka kwambiri pamtengo wapakati. Sensa imathanso kuyesedwa mochulukira kuti muwone ngati sensor ya Hall yawonongeka. Sensa ya Hall yokhala ndi mphamvu ziwiri zotulutsa mphamvu 0 voteji ikamva 0 pano; ikazindikira zina kuposa 0 pakali pano, zabwino, zoipa ndi kukula kwa voliyumu yotulutsa zimasintha ndi kukula ndi komwe kumachokera.

4. Kuyesedwa kwa ma relay

Zolakwika zodziwika bwino za ma relay ndi monga kulumikizidwa kwa ma coil, kulumikizana kosatseka, kukana kukhudzana kwambiri, ndi kuyatsa kulumikizana. Njira yabwino yoyezera ngati relayyo ndiyabwinobwino ndikuwonjezera mphamvu pa relay, kugwiritsa ntchito voteji yovotera pa koyilo, ndiyeno kuyesa kupitiliza kwa kulumikizana.

Pamafunso azinthu, chonde onanitsamba mankhwala, nanunso mwalandiridwaLumikizanani nafekudzera muzomwe zili pansipa, tidzakuyankhani mkati mwa 24.
