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.
