Amabhodi esekethe aphrintiwe asetshenziswa kabanzi kuma-elekthronikhi nobuchwepheshe obuhlukahlukene, okuwenza abe amadivaysi abaluleke kakhulu. Kungakhathaliseki ukuthi iselula, ikhompuyutha noma umshini oyinkimbinkimbi, uzothola ukuthi i-pcb inesibopho somsebenzi wedivayisi. Uma ibhodi lesekethe eliphrintiwe linamaphutha noma izinkinga zokukhiqiza, lingabangela ukuthi umkhiqizo wokugcina ungasebenzi kahle futhi kubangele ukuphazamiseka. Ngaphansi kwalezi zimo, abakhiqizi kuzodingeka bakhumbule le mishini futhi bachithe isikhathi esiningi nezinsiza ukulungisa iphutha.
Lesi ngesinye sezizathu eziyinhloko ezenza abathuthukisi abaningi baphendukele kubaklami be-pcb nabakhiqizi bokukhiqiza nokuhlola okuphrofeshinali.
Kungani ibhodi le-pcb kufanele lihlolwe?
Isigaba sokuhlola sokwenziwa kwe-PCB singesinye sezigaba ezibaluleke kakhulu. Uma ungahloli ibhodi lakho le-pcb, kungase kube namaphutha athile nezinkinga ezinganakwa ngesikhathi sesiteji sokukhiqiza. Lezi zinkinga zingagcina ziholele ekuhlulekeni kwenkundla kanye namaphutha. Ukunciphisa ithuba lokwehluleka nokugcina ukwaneliseka kwamakhasimende, kubalulekile ukwenza izinqubo zokuhlola ukuqinisekisa ukuthi amabhodi wesifunda aphrintiwe kanye nezingxenye zisebenza ngokugcwele. Kunenqubo yokuhlola kuso sonke isigaba sokukhiqiza, esikuvumela ukuthi ukhombe amaphutha nezinkinga ngaphambi kwesikhathi kunesigaba sokugcina sokuhlola.
Idizayini yebhodi lesifunda ephrintiwe kanye nezinkampani ezikhiqizayo ngokuvamile zinezinqubo zokuhlola ngokucophelela neziphelele ukuze kuqinisekiswe ukuthi ibhodi lesifunda eliphrintiwe lokugcina lisezingeni eliphezulu kakhulu.
Ukuhlolwa kwengxenye ye-PCB
Isigaba sokuhlola ngokuvamile siyisigaba esiphelele futhi sidinga ukunakwa okukhulu emininingwaneni. Ibhodi pcb yakhiwa izingxenye ezihlukahlukene eziyinkimbinkimbi. Lokhu kungafaka ama-capacitor, ama-resistors, ama-transistors, ama-diode nama-fuse. Lezi yizingxenye eziyinhloko ezidinga ukuhlolwa noma yiziphi izimpawu zokungahambi kahle kanye nokungasebenzi kahle.
Ama-Capacitors-Capacitors amadivayisi amancane kagesi agcina amandla ngendlela yamasimu kagesi. Ama-Capacitor anesibopho sokuvimbela ukugeleza kwamandla aqondile futhi enze kube nokwenzeka ukugcina amandla angaqondile ngenkathi ugcina amandla. Ukuhlola lawa ma-capacitor, kusetshenziswa i-voltage ukuze kuhlolwe ukuthi asebenza njengoba kudingeka. Uma kungenjalo, imiphumela ehlukene ingase ivele, ebonisa amasekhethi amafushane, ukuvuza, noma ukwehluleka kwe-capacitor.
I-Diode-A diode iyisisetshenziswa se-elekthronikhi esincane esingadlulisa amandla akhona ohlangothini olulodwa. Uma idlulisa i-current inhlangothi eyodwa, ivimba i-current reverse. I-diode iyidivayisi ebucayi kakhulu, futhi ukuyihlola kudinga ukunakekelwa. Kunconywa ukuthi uthintane nochwepheshe ngaphambi kokuhlola izingxenye ezibucayi ukuze uvimbele umonakalo
I-Resistor-Resistor ingenye yezingxenye eziyinhloko zebhodi le-pcb. Lawa madivaysi amancane e-elekthronikhi anamatheminali amabili akhiqiza i-voltage kusuka kumanje. Ukuze uhlole lokhu kumelana, ungasebenzisa i-ohmmeter. Uma ukumelana sekuhlukanisiwe, ungasebenzisa i-multimeter yedijithali futhi uxhume umkhondo wokumelana nokuhlolwa. Uma ukufundwa kuphezulu kakhulu, kungase kube ngenxa ye-resistor evulekile.
Njengoba ibhodi le-pcb lakhiwe izingxenye ezihlukahlukene zikagesi eziyinkimbinkimbi, kubaluleke kakhulu ukuhlola ukuthi ibhodi le-pcb linamaphutha noma amaphutha angabangela ukuthi ibhodi lesifunda lingasebenzi kahle. Ingxenye ngayinye kufanele iqashwe futhi ihlolwe ukuze kugcinwe ibhodi lesifunda eliphrintiwe elisebenzayo linamandla alo agcwele
Fastline Circuits Co., Limited.ithatha izici ezintathu ezingenhla njengamaphoyinti empumelelo, futhi amakhasimende angakhetha kalula umakhi olungile. Ngesikhathi esifanayo, kufanele sinake ukuxhumana nokuhwebelana nabakhiqizi, ukuze izinhlangothi zombili zenze isimo "esizuzisayo futhi siwine", futhi sikhuthaze kangcono ukubambisana kwephrojekthi yomkhiqizo.
