1. Ukwehluleka okuvamile kwebhodi lesifunda se-PCB kugxile kakhulu ezingxenyeni, njengama-capacitor, resistors, inductors, diodes, triodes, field effect transistors, njll. Ama-chips ahlanganisiwe nama-crystal oscillator awonakele ngokusobala, futhi kunengqondo kakhulu ukwahlulela ukwehluleka. yalezi zingxenye Ingabonwa ngamehlo.Kukhona amamaki avuthayo asobala ngaphezulu kwezingxenye ze-elekthronikhi ezinomonakalo osobala.Ukwehluleka okunjalo kungaxazululwa ngokushintsha ngokuqondile izingxenye eziyinkinga ufake ezintsha.
2. Akuwona wonke umonakalo ezingxenyeni ze-elekthronikhi ongabonwa ngeso lenyama, futhi amathuluzi okuhlola ochwepheshe ayadingeka ukuze kulungiswe.Amathuluzi okuhlola asetshenziswa ngokuvamile ahlanganisa: i-multimeter, i-capacitance meter, njll. Uma kutholwa ukuthi i-voltage noma i-current ye-electronic component ayikho ngaphakathi kwebanga elivamile, kusho ukuthi kunenkinga ngengxenye noma ingxenye yangaphambilini.Yishintshe futhi uhlole ukuze ubone ukuthi ijwayelekile yini.
3. Ngezinye izikhathi lapho sihlinzeka ngezingxenye ebhodini le-PCB, sizobhekana nesimo sokuthi ayikho inkinga engatholwa, kodwa ibhodi lesifunda alikwazi ukusebenza ngokujwayelekile.Eqinisweni, lapho uhlangabezana nalolu hlobo lwesimo, izikhathi eziningi kungenxa yokuxhumana kwezingxenye ezihlukahlukene phakathi nenqubo yokufaka ukuthi ukusebenza kungase kungazinzi;ungazama ukwahlulela ububanzi obungaba khona bephutha ngokusekelwe ku-current kanye ne-voltage, futhi unciphise indawo yephutha ;bese uzama ukufaka esikhundleni sengxenye esolwayo kuze kutholakale ingxenye yenkinga.
