Kusuka emhlabeni we-PCB.
Noma ngabe yiBhodi eyenziwe ngomunye umuntu noma ibhodi le-PCB yakhelwe futhi yenziwe nguwe, into yokuqala ukuthola ukuthi ihlole ubuqotho beBhodi, njenge-Tinning, imifantu, imibuthano emifushane, iziqebele ezivulekile, nokumba. Uma iBhodi lisebenza kakhulu liba namandla, khona-ke ungabheka inani lokumelana phakathi kokunikezwa kwamandla kanye ne-wire yomhlabathi ngendlela.
Ngaphansi kwezimo ezijwayelekile, ibhodi elenziwa ngokwalo lizofaka izakhi ngemuva kokuthi i-Tinning iphothuliwe, futhi uma abantu bekwenza, kumane nje kuyinto egcwele i-PCB yePCB enezimbobo. Udinga ukufaka izakhi ngokwakho lapho uyithola. .
Abanye abantu banemininingwane eminingi ngamabhodi we-PCB abaklama, ngakho-ke bathanda ukuvivinya zonke izinto ngasikhathi sinye. Eqinisweni, kungcono ukukwenza kancane kancane.
I-PCB Circuit Board ngaphansi kokulungisa iphutha
Ukulungisa iphutha le-PCB entsha kungaqala engxenyeni yokuhlinzekwa kwamandla. Indlela ephephe kunazo zonke ukubeka i-fuse bese ixhumanisa ukunikezwa kwamandla (uma kwenzeka kunjalo, kungcono ukusebenzisa amandla okusinyazwa amandla).
Sebenzisa ukuhanjiswa kwamandla okuzinzile ukusetha okuvikelekile okuphezulu kokuvikelwa, bese kukhulisa kancane kancane amavolushi awo wokuzinza wamandla wokuzinza. Le nqubo idinga ukuqapha okokufaka kwamanje, ukufakwa kwamandla okufaka kanye nokukhipha ivoloji yeBhodi.
Lapho i-voltage ilungiswe phezulu, akukho ukuvikela okungamanje kwangemva kokukhishwa kanye nokukhishwa kwamandla okukhishwa kuyinto evamile, kusho ukuthi ukunikezwa kwamandla kwebhodi akunankinga. Uma i-voltage ejwayelekile yokuphuma noma ukuvikelwa okuphezulu kwamanje kuyadlula, khona-ke imbangela yephutha kufanele iphenywe.
Ukufakwa kwengxenye ye-Circuity Board Contencent
Kancane kancane faka amamojula ngesikhathi senqubo yokulungisa iphutha. Lapho kufakwa imodyuli ngayinye noma amamojula ambalwa, landela lezi zinyathelo ezingenhla zokuhlola, ezisiza ukugwema amanye amaphutha afihliwe ekuqaleni komklamo, noma amaphutha wokufaka wezakhi, ezingaholela ekuvuthweni okungaphezulu. Izakhi ezimbi.
Uma kwehluleka kwenzeka ngesikhathi senqubo yokufaka, izindlela ezilandelayo zivame ukusetshenziswa ukuxazulula inkinga:
Indlela yokuxazulula inkinga ENYE: Indlela yokulinganisa i-Voltage.
Lapho kwenzeka ukuvikelwa okuphezulu kwamanje, ungagijimisi ukuhlukaniswa izakhi, okokuqala qinisekisa i-voltage ye-Power Supply Pine ye-chip ngayinye ukuze ibone uma kusezingeni elijwayelekile. Bese uhlola i-voltage yereferensi, i-voltage esebenzayo, njll.
Isibonelo, lapho kuvulwa i-Silicon Transtoror, ivolumu le-genction lizoba cishe ngo-0.7V, futhi i-ce cection imvamisa izoba ngu-0.3v noma ngaphansi.
Lapho kuhlolwa, kutholakala ukuthi i-voltage ye-BE BUST iphakeme kune-0.7v (ama-transtors akhethekile anjengeDarlington awafakwanga), khona-ke kungenzeka ukuthi i-gerch ivulekile. Ngokulandelana, hlola i-voltage ephuzwini ngalinye ukuze ususe iphutha.
Indlela Yokuxazulula Izinkinga ezimbili: Indlela yokujova yesiginali
Indlela yokujova yesiginali inenkinga enkulu kunokulinganisa amagesi. Lapho umthombo wesiginali uthunyelwa kwi-terminal yokufaka, sidinga ukukala i-waveform yephuzu ngalinye ukuze uthole iphuzu lephutha ku-waveform.
Vele, ungasebenzisa futhi ama-tweezers ukuthola i-terminal yokufaka. Indlela ukuthinta i-terminal yokufaka ngama-tweezers, bese ubheka impendulo ye-terminal yokufaka. Ngokuvamile, le ndlela isetshenziswa esimweni semijikelezo ye-audio ne-video amplifier (Qaphela: umjikelezo oshisayo waphansi kanye nomjikelezo ophakeme we-voltage) awusebenzisi le ndlela, kuthambekele ezingozini zikagesi ukushaqeka).
Le ndlela ibona ukuthi isigaba esedlule sijwayelekile futhi isigaba esilandelayo siphendula, ngakho-ke iphutha alikho esigabeni esilandelayo, kodwa esiteji esedlule.
Indlela yokuxazulula izinkinga ezintathu: Okunye
Lezi ezimbili ezingenhla zilula nezindlela eziqondile. Ngaphezu kwalokho, ukubona, ukuhogela, ukulalela, ukuthinta, njll., Okuvame ukushiwo, bangenjiniyela abadinga ulwazi oluthile ukuze bakwazi ukuthola izinkinga.
Ngokuvamile, "bheka" akufanele ubheke isimo semishini yokuhlola, kodwa ukubona ukuthi ukubukeka kwezakhi kuqediwe; "Ukuhogela" ikakhulukazi kubhekisa ukuthi iphunga lezakhi lingajwayelekile, njengephunga lokushiswa, electrolyte, njll. Izinto ezijwayelekile zingena lapho zilimele.
Futhi "ukulalela" ikakhulukazi ukulalela ukuthi ngabe umsindo webhodi uvamile ngaphansi kwezimo zokusebenza; Mayelana ne- "Thintant", akuthinti ukuthi izakhi zikhululiwe, kepha ukuzwa ukuthi izinga lokushisa lezinto zijwayelekile ngesandla, ngokwesibonelo, kufanele kube kubanda ngaphansi kwezimo zokusebenza. Izakhi ziyashisa, kepha izingxenye ezishisayo zibanda ngokungafanele. Musa ukucindezela ngezandla zakho ngqo ngesikhathi senqubo ethinta inhliziyo ukuvikela isandla ekushisweni ngokushisa okuphezulu.
