Ukwenza a PCB ibhodi akuyona inqubo elula yokuqedela ibhodi, ukubhoboza umgodi wokushaya izingxenye. Ukukhiqizwa kwe-PCB akunzima, ubunzima bukhona ekuxazululeni inkinga ngemuva kokukhiqizwa. Kungakhathaliseki ukuthi ama-hobbyists ngamanye noma onjiniyela bemboni, izinkinga zokulungisa iphutha le-PCB ziyikhanda impela, njengabahleli bezinhlelo bahlangabezana nezimbungulu.

Abanye abantu banesifiso esiqinile sokulungisa iphutha ibhodi lesifunda le-PCB, njengabahleli bohlelo ekuxazululeni izimbungulu, izinkinga ezivamile zebhodi lesifunda le-PCB akuzona ezimbalwa, izinkinga ezivamile ngaphezu kokuklanywa kwebhodi lesifunda, ukulimala kwezinto ze-elekthronikhi, isifunda esifushane sesifunda, ikhwalithi yezingxenye , Iphutha lokunqanyulwa kwebhodi lesifunda le-PCB aliyona embalwa.

I-resistor eyonakele yombala wendandatho

Amaphutha ejwayelekile ebhodi yesifunda se-PCB agxilwe kakhulu kuzinto, njenge-capacitance, ukumelana, i-inductance, i-diode, i-transistor, ithubhu yomphumela wensimu, njll, nomonakalo osobala we-chip edidiyelwe ne-crystal oscillator, kanye nendlela enembile ukwahlulela amaphutha yalezi zingxenye zingabonakala ngamehlo. Kunezimpawu ezisobala ezivuthayo ebusweni bezinto zikagesi ezisobala ngokusobala. Ukwehluleka okunjalo kungaxazululwa ngokumane nje kushintshwe izingxenye ezinamaphutha kufakwe ezintsha.

Ingxenye esolisiwe esolisiwe? Akuyona into ephukile

Vele, akuwona wonke umonakalo wezinto zikagesi ongabonwa ngeso lenyama, njengokumelana okushiwo ngenhla, amandla, ukuhlolwa okumbili noma okuthathu, kwezinye izimo, umonakalo awubonakali ebusweni, udinga ukusebenzisa ubuchwepheshe amathuluzi wokuhlola okondla, ukuhlolwa okusetshenziswa kakhulu nge: Lapho i-multimeter noma i-capacitor meter ithola ukuthi i-voltage noma i-current yento ye-elekthronikhi ayikho ebangeni elijwayelekile, kukhombisa ukuthi kunenkinga ngengxenye noma ingxenye yangaphambilini. Faka okunye esikhundleni bese uhlola ukuthi kujwayelekile yini.

Ibhodi lesifunda ngaphandle kokulimala ekubukekeni nangaphandle kokutholwa kwamaphutha

Uma into iphukile, ingatholwa ngokubheka iso noma ukuthola ithuluzi. Kodwa-ke, kwesinye isikhathi lapho sinikeza ingxenye ebhodini le-PCB, sizohlangabezana nesimo sokuthi inkinga ayikwazi ukutholwa, kepha ibhodi lesifunda alikwazi ukusebenza kahle. Abaqalayo abaningi abanakho okunye ngaphandle kokwakha ibhodi elisha noma ukulithenga. Eqinisweni, ezimweni eziningi, izingxenye zenqubo yokufaka, ngenxa yokuhlanganiswa kwezinto ezahlukahlukene, kungahle kube nokusebenza okungazinzile.

Ibhodi lesifunda lesifunda block block

Kulokhu, insimbi yehlulekile ukusiza, ungazama ukuthola ukuthi kungenzeka yini ukuthi kunephutha ngokuya ngamandla wamanje namandla kagesi, ngangokunokwenzeka ukunciphisa, onjiniyela abanolwazi bangakwazi ukuthola ngokushesha indawo enephutha, kepha akuqinisekisiwe ngo-100% ukuthi iyiphi ingxenye ethile ephukile. Okuwukuphela kwekhambi ukuzama ukufaka endaweni yomsolwa ize itholakale. Ngonyaka owedlule, nebhodi lami lomama le-laptop, amanzi asesikhathini esiyinhloko sokulungiswa kwakudingeka abone iphutha, futhi aguqule izinto ezintathu kunqubo yokulungiswa, i-chip yokuphakela ugesi, i-diode, idivayisi yokushaja ye-USB (ilaptop socket blue that, shutdown condition can rejista imishini), eyokugcina inokusetshenziswa kokufakwa kwesikrini okusolisayo nge-chip ukuthola i-chip, Ekugcineni kwanqunywa ukuthi kube yisifunda esifushane entweni eseceleni kwe-chip yaseSouthbridge.

Circuit ibhodi fly wire

Lokhu okungenhla empeleni kuyinkinga yezingxenye ze-elekthronikhi, yebo, ngoba ibhodi lesifunda le-PCB njengomsuka wezinto, ukwehluleka kwebhodi lesifunda kufanele futhi kube khona, isibonelo esilula kakhulu yingxenye efile yethini, ngenxa yenqubo yokukhiqiza, INQUBO ye-PCB ukugqwala, kungahle kube nenkinga yomugqa ephukile. Kulokhu, uma ungakwazi ukugcwalisa ucingo, ungasebenzisa kuphela ithusi lethusi elihle ukuxazulula inkinga.
