Kulezi zinsuku, umkhuba oqhubekayo wemikhiqizo ye-elekthronikhi udinga ukwakheka okunezinhlangothi ezintathu zamabhodi wesifunda ama-multilayer aphrintiwe. Kodwa-ke, ukufakwa kwesendlalelo kuphakamisa izingqinamba ezintsha ezihlobene nalombono wokuqamba. Enye yezinkinga ukuthola ukwakheka okuyisisekelo kwephrojekthi.

Njengoba kubhalwe imibuthano ephrintiwe eminingi futhi ephrintiwe yezendlalelo eziningi, ukufakwa kwama-PCB kuse kubaluleke kakhulu.

Idizayini enhle ye-PCB ibalulekile ukunciphisa imisebe ye-PCB loops kanye nemibuthano ehlobene. Ngokuphambene nalokho, ukunqwabelana okubi kungakhulisa kakhulu imisebe, okuyingozi kusuka endaweni yokuphepha.
Yini i-PCB Statup?
Ngaphambi kokuqedwa kwesakhiwo sokugcina, isendlalelo se-PCB Statup the insulator ne-PCP ye-PCB. Ukuthuthukisa ukufaka okusebenzayo kuyinqubo eyinkimbinkimbi. I-PCB ixhuma amandla nezibonakaliso phakathi kwamadivayisi omzimba, kanye nokubekwa okulungile kwezinto zokwenziwa kwebhodi yokujikeleza ngqo ngqo.

Kungani sidinga ukuzala i-PCB?
Ukuthuthukiswa kwe-PCB Statup kubalulekile ekwakheni amabhodi wesifunda afanele. I-PCB Statup inezinzuzo eziningi, ngoba ukwakheka kwe-multilayer kungathuthukisa ukusatshalaliswa kwamandla, kuvikele ukuphazamiseka kwamandla, ukunciphisa ukuphazamiseka kwesiphambano, nokusekela ukuhanjiswa kwesiginali okuphezulu.

Yize inhloso enkulu yokufaka ukubeka indawo yokubeka amasekethe amaningi we-elekthronikhi ebhodini elilodwa ngokusebenzisa izingqimba eziningi, isakhiwo esihlanganisiwe sama-PCB futhi sinikeza nezinye izinzuzo ezibalulekile. Lezi zinyathelo zibandakanya ukunciphisa ubungozi bamabhodi wesifunda kumsindo wangaphandle kanye nokunciphisa i-crosstalk kanye nezinkinga zokuvimbela ezinhlelweni zejubane eliphezulu.

Isitakuphu se-PCB esihle singasiza futhi ukuqinisekisa izindleko zokukhiqiza zokugcina eziphansi. Ngokukhulisa ukusebenza kahle kanye nokwenza ngcono ukuhambisana kwe-electromagnetic yawo wonke amaphrojekthi, ukufakwa kwe-PCB kungagcina ngempumelelo isikhathi nemali.

Izindlela zokuqapha nemithetho ye-PCB Lamia
● Inani lezingqimba
Ukufakwa okulula kungafaka ama-PCB angqimba amane, kuyilapho amabhodi ayinkimbinkimbi adinga ukugcwala okulandelanayo okulandelana. Yize kuyinkimbinkimbi kakhulu, inani eliphakeme lezendlalelo livumela abaqambi ukuba babe nesikhala esithe xaxa ngaphandle kokukhulisa ubungozi bokubhekana nezixazululo ezingenakwenzeka.

Ngokuvamile, izingqimba eziyisishiyagalombili noma ngaphezulu ziyadingeka ukuthola ilungiselelo elihle kakhulu lesendlalelo kanye nesikhala sokukhulisa ukusebenza. Kusetshenziswa izindiza ezisezingeni eliphakeme kanye nezindiza zamandla kumabhodi we-multilayer kunganciphisa nemisebe.

● ukuhlelwa kwesendlalelo
Ukuhlelwa kwesendlalelo sethusi kanye nesendlalelo esifaka esisendaweni esungule umjikelezo kwakha ukusebenza kwe-PCB Screetlap. Ukuvimbela impi ye-PCB, kuyadingeka ukwenza isigaba sesiphambano sebhodi silingana futhi silinganise lapho sibeka izingqimba. Isibonelo, ebhodini eliyisishiyagalombili, ukushuba kwezendlalelo zesibili neyesikhombisa kufanele kube okufanayo ukuze kufezekiswe ibhalansi engcono kakhulu.

Ungqimba lwesiginali kufanele njalo lusondelene nendiza, ngenkathi indiza yamandla nendiza yekhwalithi ihlanganiswa ngokuqinile. Kungcono ukusebenzisa izindiza eziningi zomhlaba, ngoba zinciphisa imisebe kanye nokuvikelwa phansi komhlaba okuphansi.

● Uhlobo lwezinto ezibonakalayo
Izakhiwo ezishisayo, ezenziwa ngomshini, nezikagesi ze-substrate ngayinye nokuthi zihlangana kanjani zibalulekile ekukhetheni kwezinto ze-PCB Laminate.

Ibhodi yesekethe livame ukwakhiwa ngesisekelo esinamandla se-fiberstrate esinamandla, esinikeza ubukhulu kanye nobulukhuni be-PCB. Amanye ama-PCB aguquguqukayo angenziwa nge-Plastistics eguquguqukayo yokushisa ephezulu.

Ungqimba olungaphezulu luyi-foil elincanyana elenziwe nge-foil ye-topper enamathiselwe ebhodini. I-Copper ikhona ezinhlangothini zombili ze-PCB eseceleni elimbili, futhi ubukhulu bethusi buyahlukahluka ngokuya ngenani lezendlalelo se-PCB Stack.

Mboza phezulu kwe-foil yethusi nge-mask yomthengisi ukwenza umkhondo wethusi uxhumane nezinye izinsimbi. Lokhu okubalulekile kubalulekile ukusiza abasebenzisi ukuthi bagweme ukuthengisa indawo efanelekile yezintambo ze-jumper.

Isendlalelo sokuphrinta isikrini sisetshenziswa ku-solder imaski ukungeza izimpawu, izinombolo nezinhlamvu ukwenza lula umhlangano futhi uvumele abantu baqonde kangcono ibhodi yesekethe.

● Thola i-wiring nangezimbobo
Abaqambi kufanele bakwazi ukwenza amasiginali wejubane eliphakeme kungqimba eliphakathi phakathi kwezendlalelo. Lokhu kuvumela indiza yomhlabathi ukuhlinzeka ngokuvikelwa okuqukethe imisebe ekhishwe kusuka kulayini ngesivinini esikhulu.

Ukubekwa kwezinga lesiginali eliseduze neleveli yendiza kuvumela ukubuyiselwa kwamanje ukugeleza endizeni esondele, ngaleyo ndlela kunciphise indlela yokubuyisa indlela. Akukho ukusebenzisa amandla anele phakathi kwamandla asondelene namandla aphansi kanye nezindiza zomhlaba ukuhlinzeka ngenkohliso ngaphansi kwama-500 MHZ usebenzisa amasu ajwayelekile wokwakha.

● Ukuhlukaniswa phakathi kwezingqimba
Ngenxa yokukhohlisa okuncishisiwe, ukuhlangana okuqinile phakathi kwesiginali nendiza yokubuya yamanje kubalulekile. Izindiza zamandla nezindawo zomhlaba kufanele futhi zihlanganiswe ngokuqinile ndawonye.

Izendlalelo zesiginali kufanele ngaso sonke isikhathi zisondelene komunye nomunye noma ngabe zitholakala ezithombeni eziseduzane. Ukuhlangana okuqinile nokuhlukanisa phakathi kwezingqimba kubalulekile ezinkomeni ezingaphazanyiswa nokusebenza okuphelele.

ngamafuphi
Kunemiklamo eminingi ehlukene ye-PCB ye-PCB ye-PCB ku-PCB Stacting Technology. Lapho izingqimba eziningi zibandakanyeka, indlela enezinhlangothi ezintathu ezibheka ukwakheka kwangaphakathi nokuhlelwa komhlaba kumele kuhlanganiswe. Ngejubane eliphakeme elisebenzayo lamasekethe anamuhla, ukwakheka ngokucophelela kwe-PCB-up design kumele kwenziwe ukuthuthukisa amandla okuhambisa nokunciphisa umkhawulo wokuphazamiseka. I-PCB eklanyelwe kabi inganciphisa ukudluliswa kwesiginali, ukuzokwenza, ukuhambisa amandla, kanye nokwethembeka kwesikhathi eside.
