Cov ntawv thov
Xov tooj, Moos, Khoom siv kho mob, Cov khoom siv digital, Cov khoom ua si, Cov khoom siv nom tswv, Cov khoos phis tawj sau ntawv, Cov qhov cub microwave, Cov cua txias, Cov khoom siv hluav taws xob hauv tsev, Cov khoom siv tswj tsis siv neeg.
Daim Ntawv Ceeb Toom Txog Kev Tswj Xyuas
- Thov tsis txhob kov cov khoom siv nrog tes liab qab, vim tias electrode tej zaum yuav xeb.
- Tsis txhob rub cov hlau txhuas ntau dhau vim tias cov hlau yuav tawg lossis qhov chaw vuam yuav tawm.
- Cov circuits siv transistor switching, Cov circuit constants rau heft ntawm transistor yog xaiv zoo tshaj plaws kom ruaj khov, yog li thov ua raws li nws thaum koj tsim ib lub circuit.
- Cov cuab yeej ntsuas suab sib nqus raug tsav los ntawm qhov zaus nkag, cov yam ntxwv ntawm qhov zaus uas tau muab tsuas yog tau txais thaum siv 1/2 duty square wave (Vb-p). Cov neeg siv kawg yuav tsum paub qhov tseeb tias cov yam ntxwv ntawm qhov zaus yuav hloov pauv ntau yam duab nrog rau kev siv ntau yam nthwv dej, xws li sine wave, square wave (Vb-p) lossis lwm yam nthwv dej.
- Thaum lwm yam voltage raug siv dua li qhov pom zoo, cov yam ntxwv ntawm zaus kuj yuav hloov pauv.
- Thov khaws qhov deb kom zoo rau lub zog sib nqus thaum koj khaws cia, hloov pauv thiab teeb tsa.
Kev Sib Txuas Thiab Kev Teeb Tsa
- Thov nyeem cov lus qhia ntawm HYDZ, yog tias xav tau cov khoom siv soldering.
- Kev ntxuav cov khoom no tsis raug lees txais, vim nws tsis tau ntsuas.
- Thov tsis txhob siv daim kab xev lossis lwm yam khoom los npog lub qhov, vim qhov no yuav ua rau kev ua haujlwm tsis xwm yeem.
