Alaabta qallalan | Hal maqaal ayaa helaya jiilka, cabbiraadda iyo xakamaynta qulqulka tamarta beddelka
Qulqulka awoodda beddelka waa lama huraan. Ujeeddadeenna kama dambaysta ahi waa in aan hoos u dhigno wax-soo-saarka heer la aqbali karo. Xalka ugu muhiimsan ee lagu gaari karo ujeedadan waa in laga fogaado abuuritaanka dooxooyinka. Marka hore Iyo sababta. Marka la beddelo SWITCH, hadda ku jira inductanc-kaSii akhri -
Korontada khaldan ee ku xidhan qiiqa wareegga togan iyo taban, sidee looga fogaanayaa ceebtan?
Mashaariic badan oo injineerada hardware ah ayaa lagu dhammeeyaa sabuuradda godka, laakiin waxaa jira ifafaale ah in si lama filaan ah loogu xiro terminaalka togan iyo kuwa taban ee korontada, taas oo keenta in qaybo badan oo elektiroonig ah ay gubaan, iyo xitaa guddiga oo dhan waa la burburiyaa, waana in la welded ag ...Sii akhri -
Talooyin dhowr ah oo lagu xukumayo saturation inductance
Inductance waa qayb muhiim ah oo ka mid ah korantada DC/DC. Waxaa jira arrimo badan oo la tixgeliyo marka la dooranayo inductor, sida qiimaha inductance, DCR, cabbirka, iyo saturation current. Sifooyinka saturation ee inductors badanaa waa la fahmaa oo waxay keenaan dhibaato. Qoraalkani waxa uu ka hadli doonaa sida...Sii akhri -

1 Hordhac Kulanka guddiga wareegga, koollada alxanka ayaa lagu daabacaa suufka alxanka wareegga marka hore, ka dibna qaybo kala duwan oo elektiroonig ah ayaa lagu dhejiyaa. Ugu dambeyntii, foornada dib u soo qulqulaya ka dib, kuulyada daasadaha ah ee ku jira koollada alxanka waa m...Sii akhri -
[Alaab qallalan] Falanqaynta qoto dheer ee SMT sababta loo isticmaalo xabagta cas? (2023 Essence Edition), waad u qalantaa!
Xabagta SMT, oo sidoo kale loo yaqaan 'SMT adhesive', koollada cas ee SMT, badanaa waa koollo guduudan (sidoo kale huruud ama caddaan) si siman loo qaybiyay oo leh qallajiye, midab, dareere iyo dhejisyo kale, oo inta badan loo isticmaalo in lagu hagaajiyo qaybaha guddiga daabacaadda, guud ahaan waxaa loo qaybiyaa qaybinta ama daabacaadda birta ee meth ...Sii akhri -
[Alaabada qallalan] SMT-xaleefyo balastar ah oo kala soocida daasadaha daasadaha ah ee habaynta, imisa ayaad taqaan? (2023 Nuxurka), waad u qalantaa!
Noocyo badan oo alaabta ceeriin wax soo saarka ayaa loo isticmaalaa habaynta balastar SMT. Tinnote waa tan ugu muhiimsan. Tayada koollada tiintu waxay si toos ah u saameyn doontaa tayada alxanka ee farsamaynta balastarrada SMT. Dooro noocyada kala duwan ee tinnuts. Aan si kooban u baro...Sii akhri -
Hal maqaal ayaa fahmaya | Waa maxay aasaaska doorashada habka farsamaynta dusha sare ee warshadda PCB
Ujeedada ugu muhiimsan ee daaweynta dusha PCB waa in la hubiyo alxanka wanaagsan ama guryaha korantada. Sababtoo ah naxaasta dabiiciga ah waxay u egtahay inay ku jirto qaabka oxides ee hawada, uma badna in lagu hayo naxaasta asalka ah muddo dheer, sidaas darteed waxay u baahan tahay in lagu daaweeyo naxaas. Waxaa jira...Sii akhri -

Ku saabsan aaladaha DIP, dadka PCB qaarkood kuma tufaan god degdeg ah!
Faham DIP DIP waa fur-in. Chips sidaan loo baakadeeyay waxay leeyihiin laba saf oo biinanka ah, kuwaas oo si toos ah loogu alxan karo godad godad leh oo qaab-dhismeed DIP ah ama lagu alxan karo meelaha alxanka leh ee leh godadka isku midka ah. Aad bay ugu habboon tahay in la xaqiijiyo alxanka daloolinta guddiga PCB ...Sii akhri -
Waa maxay sababta CAN baska terminalka iska caabinta 120Ω?
Iska caabinta meesha baska ee CAN guud ahaan waa 120 ohms. Dhab ahaantii, marka la nashqadeynayo, waxaa jira laba 60 ohms xadhig iska caabin ah, oo waxaa jira guud ahaan laba 120Ω noodes ee baska. Asal ahaan, dadka yaqaan baska yar ee CAN waa xoogaa. Qof kastaa wuu garanayaa tan. Waxaa jira saddex saameyn oo baska CAN...Sii akhri -
