- Nekuyera Voltage
Chinhu chekutanga chekusimbisa ndechekuti voltage yepini yega yega chip simba yakajairwa here kana kuti kwete, wobva watarisa kuti akasiyana referensi voltage akajairwa here kana kuti kwete, mukuwedzera kune poindi yemagetsi anoshanda. Semuenzaniso, silicon triode yakajairika ine BE junction voltage inosvika 0.7V, uye CE junction voltage inosvika 0.3V kana zvishoma. darlington chubhu, nezvimwewo), iyo BE junction inogona kuvhurwa.
2.signal injection
Kuchaisa chiratidzo chekuisa, uyezve kudzoka kuyera waveform panzvimbo yega yega, tarisa kuti kana zvakajairika, kuti tiwane chikanganiso chatinoshandisa dzimwe nguva nzira iri nyore, nechisimba muruoko, semuenzaniso, kubata pamatanho ese iyo inopinza, iyo inobuda padivi pekuita, iyo inosimudzira dunhu sengeodhiyo vhidhiyo inowanzo shandisa (asi cherechedza kuti ndiro inopisa kana yakakwira voltage wedunhu, haigone kushandisa nzira iyi, zvikasadaro inogona kutungamira mukuvhunduka kwemagetsi) kana ukabata pamberi penhanho. pindura, uye bata mushure mezinga rekutanga, ipapo dambudziko riri muchikamu chekutanga, rinofanira kutarisa pakuongorora
Dzimwe nzira dzekutsvaga dzakaremara PCB
Kune dzimwe nzira dzakawanda dzekutsvaga nzvimbo dzine dambudziko, sekuona, kunzwa, kunhuwidza, kubata, nezvimwe.
1”Kuona” zvinoreva kuona kana chikamu chacho chine kukuvara kuri pachena, sekutsemuka, kusviba, deformation, zvichingodaro;
2.”Teerera” ndiko kuteerera kana ruzha rwebasa rwuri rwenguva dzose, sekuti vamwe havafanire kuridza zvinhu murin’i, ruzha rwenzvimbo haruna ruzha kana rusina kujairika, zvichingodaro;
3 "Smell" ndeyekutarisa kunhuhwirira, sekunhuhwirira kwekutsva, kunhuwa kwe capacitor electrolyte, nezvimwewo, kune vane ruzivo rwemagetsi ekugadzirisa vashandi, izvo zvinonyanya kunzwisiswa nekunhuhwirira uku;
4.Kuti "kubata" zvinoreva kuedza kupisa kwechigadzirwa nemaoko kuti uone kana chiri chemazuva ose, sekupisa zvakanyanya kana kutonhora zvakanyanya.
Mimwe midziyo yemagetsi, kana yaizopisa kana ichishanda, kana munhu akabata iyo inotonhora, inogona kutongerwa kuti haishande. Asi kana kuchipisa zvakanyanya pazvisingafanirwe kana kupisa zvakanyanya pazvinofanira kunge zviri, hazvisi kuzoshanda. General power transistor, voltage regulator chip, nezvimwewo, kushanda pa70 degrees pazasi hapana zvachose dambudziko. Ko 70 madhigirii anotaridzika sei? Kana ukadzvanya ruoko rwako pairi, unogona kuibata kweanopfuura masekonzi matatu, zvinoreva kuti tembiricha iri pasi pe70 degrees.
