1. Ukungaphumeleli kwebhodi yesekethe ye-PCB eqhelekileyo kugxininiswe kumacandelo, njenge-capacitors, resistors, inductors, diodes, triodes, i-transistors ye-field effect, njl njl. Ii-chips ezidibeneyo kunye ne-crystal oscillators zibonakaliswe ngokucacileyo, kwaye i-intuitive ngakumbi ukugweba ukungaphumeleli. kula macandelo Inokubonwa ngamehlo.Kukho amanqaku acacileyo ngakumbi atshisayo kumphezulu wamacandelo e-elektroniki anomonakalo ocacileyo.Ukusilela okunjalo kunokusonjululwa ngokutshintsha ngokuthe ngqo amacandelo ayingxaki ngamatsha.
2. Ayingawo wonke umonakalo kumacandelo e-elektroniki unokujongwa ngeso lenyama, kwaye izixhobo zokuhlola zobungcali ziyafuneka ukuze kugcinwe.Izixhobo zokuhlola ezisetyenziswa ngokuqhelekileyo ziquka: i-multimeter, i-capacitance meter, njl. Xa kuchongwa ukuba i-voltage okanye i-current yecandelo lombane ayikho ngaphakathi kwinqanaba eliqhelekileyo, kuthetha ukuba kukho ingxaki kunye necandelo okanye inxalenye yangaphambili.Yitshintshe kwaye ujonge ukuba iqhelekile na.
3. Ngamanye amaxesha xa sinikezela ngamacandelo kwibhodi yePCB, siya kuhlangabezana nemeko yokuba akukho ngxaki inokufunyanwa, kodwa ibhodi yesekethe ayikwazi ukusebenza ngokuqhelekileyo.Enyanisweni, xa udibana nolu hlobo lwemeko, amaxesha amaninzi ngenxa yokulungelelaniswa kwamacandelo ahlukeneyo ngexesha lenkqubo yokufakela ukuba ukusebenza kunokungazinzi;ungazama ukugweba uluhlu olunokwenzeka lwempazamo ngokusekwe kumbane kunye nombane, kwaye unciphise indawo yempazamo ; emva koko uzame ukufaka endaweni yecandelo elirhanelwayo de kufumaneke indawo yengxaki.
