Ungawubuyisela njani umzobo wesekethe nge ibhodi yesekethe?

Xa ufumana imveliso, uninzi lwamaxesha, asinayo idayagramu yesekethe, ke, kule meko, indlela yokuxelela umgaqo PCB kunye nemeko yokusebenza, oku kukubuyisela umva kumzobo wesekethe oyinyani.
Xa udibana nezinto ezithile ezincinci, okanye xa kukho imfuneko, xa udibana nemveliso ye-elektroniki ngaphandle kwemizobo, kuyafuneka ukuba uzobe umzobo wesekethe ngokwendlela. Nangona kwimeko yesikali esikhudlwana, esiba nzima kakhulu, kodwa emva kokuqonda la manqaku alandelayo, ndiyakholelwa ukuba sisengayenza, isekethe elula, akukho ngxaki.

1. Khetha ivolumu enkulu, izikhonkwane ezininzi kwaye udlale indima enkulu kwizinto zesekethe ezinje ngeesekethe ezihlanganisiweyo, abaguquli, iitransistors kunye nezinye izinto ekubonisa kuzo, kwaye emva koko ukusuka kumacandelo ekubhekiswa kuwo okwaqala umzobo wepini, kunokunciphisa iimpazamo.
2. Ukuba ibhodi ye-PCB iphawulwe ngamanani azii-serial serial (anjenge-VD870, i-R330, i-C466, njl. Njl. masisetyenziswe ngobunono ekuzobeni. Ukwahlula ngokuchanekileyo izinto zento efanayo yokusebenza sisiseko sokuyilwa komzobo.
3. Ukuba inombolo ye-serial yeli candelo ayimakiswanga kwibhodi eprintiweyo, kungcono ukuba ubhale eli candelo ukwenzela ukuba kube lula ukuhlalutya nokutshekisha isekethe. Ukwenzela ukwenza i-wiring yobhedu ibe mfutshane, izinto zecandelo elifanayo elisebenzayo zilungelelaniswe ngendlela esembindini xa umenzi eyila izinto zebhodi eprintiweyo. Nje ukuba ufumane isixhobo esisembindini weyunithi, ungasilanda kwezinye izinto zeyunithi efanayo.
4. Yahlula ngokuchanekileyo intambo yomhlaba, intambo yombane, kunye nentambo yomqondiso webhodi eshicilelweyo. Thatha isekethe yokuhambisa umbane njengomzekelo, isiphelo esingalunganga setyhubhu yokulungisa edityaniswe kwisiguquli samandla sesibini sisibonda esihle samandla ombane, kwaye ucingo lomhlaba luqhagamshelene ngokubanzi nomthamo omkhulu wokucoca ulwelo, kunye neqokobhe le capacitor ephawulwe nge-polarity. Unokufumana kwakhona umgca wamandla kunye nocingo lomhlaba ukusuka kwipini yomlawuli yesiphelo. Xa ii-wiring zishicilelwe iibhodi, ukuthintela ukuzonwabisa kunye nokuchasana nokuphazamiseka, umzi-mveliso ngokubanzi ubeka ifoyile ebanzi yobhedu yocingo lomhlaba (isiphaluka esihamba rhoqo sihlala sinendawo enkulu yombumba wobhedu womhlaba), silandelwa lilaphu lobhedu umgca wamandla kunye nefoyile encinci yobhedu yomgca wesiginali. Ukongeza, kwimveliso ye-elektroniki enee-analog kunye neesekethe zedijithali, iibhodi eziprintiweyo zihlala zahlulahlula iingcingo zazo zomhlaba ukwenza iinethiwekhi ezizimeleyo ezomeleleyo, ezinokusetyenziselwa njengesiseko sokuchonga nokugweba.
5. Ukwenzela ukuthintela unxibelelwano oluninzi kakhulu lwezikhonkwane zento yokwenza iintambo zomzobo wesekethe unqamleze, oko kukhokelela kwisiphazamiso somzobo, umbane kunye nocingo olusemhlabeni lunokusebenzisa inani elikhulu leempawu zokuphela komhlaba kunye neempawu zomhlaba. . Ukuba kukho izinto ezininzi, iyunithi yesekethe nganye inokutsalwa ngokwahlukeneyo kwaye idityaniswe kunye.
6. Uyacetyiswa ukuba usebenzise iphepha lokukhangela elicacileyo ukuzoba iintambo zomhlaba, iintambo zombane, iintambo zomqondiso, kunye nezinto ngombala usebenzisa usiba olunemibala emininzi. Xa uguqula kancinane, ngokuthe ngcembe nzulu umbala ukwenza umzobo ubenomdla kwaye ubambe amehlo, ukuze uhlalutye isekethe.
7. Uqhelene nokwakheka okusisiseko kunye nokuzoba okuqhelekileyo kwezinye iisekethe zeyunithi, ezinje ngebhulorho yokulungisa, isekethe yolawulo lwevolthi kunye nesikhulisi sokusebenza, isekethe edityanisiweyo yedijithali, njl. ezinokuphucula ukusebenza komzobo.
8. Xa uzobe imizobo yesekethe, kufuneka sizame ngako konke okusemandleni ethu ukufumana imizobo yesekethe yeemveliso ezifanayo ukuze sizibonele, eziza kufumana iziphumo kabini ngesiqingatha somzamo.
Oku kungqindilili kungasentla, kubalulekile isishwankathelo, ndiyathemba ukuba kwinto yokufunda ukuya kumzobo wesekethe, ungaqala kwezi ngongoma, ukuze uyiqonde kakuhle le teknoloji, kuba esi sisiseko sabasebenzi be-elektroniki
