Emkhakheni we-elekthronikhi, i-PCB ehlukahlukene (ephrintiwe yesekethe) kudlala indima ebalulekile. Umklamo wayo nokwenziwa kwalo kunomthelela omkhulu ekusebenzeni nasekuthembekeni kwemishini yanamuhla kagesi. Le ndatshana izongena kwizici zayo ezibalulekile, ukucatshangelwa kokucatshangelwa, kanye nezindawo zohlelo ukuze kunikeze umbono ophelele. Ngokuhlaziya, singakuqonda kangcono ukubaluleka kwayo kubuchwepheshe bama-elekthronikhi.
1, ukwakheka kwebhodi le-PCB elinemikhawulo akuwona ukufakwa okulula kwamabhodi amaningi angqimba, kepha isiyalo sobunjiniyela obuyinkimbinkimbi. Esigabeni sedizayini, into yokuqala okufanele uyicabangele ubunzima nobuningi besifunda. Ngokuphishekela okuqhubekayo kokusebenza kumadivayisi wanamuhla kagesi, ubulukhuni bemibuthano luyanda, ngakho-ke ukwakhiwa kwalo kudinga ukukwazi ukufeza izidingo zobukhulu obuphezulu nomsebenzi ohlukahlukene. Ngasikhathi sinye, izidingo zokusebenza kwamadivayisi we-elekthronikhi ziyanda, futhi ukwakhiwa kwazo kudinga ukuqinisekisa ukuqina kanye nokwethenjwa kokudluliselwa kwesiginali.
2, inqubo yokukhiqiza ye-PCB ye-PCB ehlukahlukene nayo iyingxenye ebalulekile. Esigabeni sokukhiqiza, izinqubo ezithuthukile nobuchwepheshe zibalulekile. Ngokusebenzisa ubuchwepheshe obuthuthukile bokukhanyisela, ikhwalithi yokuxhumana ngokuxhumana ingathuthukiswa ngempumelelo ukuqinisekisa ukuqina kokudluliselwa kwesiginali. Ngaphezu kwalokho, ukukhetha okufanele kwezinto ezibonakalayo nakho kuyinto ekwazi ukunganakwa kwinqubo yokukhiqiza, izinkambu ezihlukile zohlelo lokusebenza zinezidingo ezihlukile zezinto zokwakha, ngakho-ke kuyadingeka ukukhetha impahla efanelekile ngokwesimo esithile sokwakha.
I-3, ibhodi le-Multi-Laner PCB linezinhlobonhlobo zezicelo emkhakheni we-elekthronikhi. Okokuqala, idlala indima ebaluleke kakhulu emishini ye-elekthronikhi ephezulu, efana nemishini yokuxhumana, i-computer Hardware nokunye. Ukuqina kwalo okuphezulu nokuqina kuvumela la madivayisi ukuthi ahlangabezane kangcono nezidingo zokusebenza zabasebenzisi. Okwesibili, emkhakheni wezogesi zeZimoto, kusetshenziswa kabanzi ezinhlelweni zemoto, njengokuhambisa, ukuzijabulisa nokunye. Ngenxa yokwethenjwa okuphezulu nokuqina kokuqina kwama-elekthronikhi wezimoto, amabhodi e-pcb ahlukahlukene aphenduke isakhi esisemqoka. Ngaphezu kwalokho, kubonise nezinzuzo zayo ezihlukile emikhakheni yemishini yezokwelapha, ukulawulwa kwezimboni nokunye.
Okokuqala, ake sigxile enqubweni yokukhiqiza yamabhodi e-PCB Double-Lawer. Ukukhiqizwa kwe-PCB yesimanje kuvame ukusebenzisa amasu athuthukile amakhemikhali etching ukwakha amaphethini wesifunda ngokumboza iphethini ekuhlolweni kwe-Copper bese usebenzisa isixazululo samakhemikhali ukuze ahlunge izingxenye ezingafuneki. Le nqubo ayidingi kuphela okokusebenza okunembile okunembile, kodwa futhi nokulawulwa kwenqubo eqinile ukuqinisekisa ikhwalithi nokuqina kweBhodi. Ekuthuthukisweni okuqhubekayo kokukhiqiza i-PCB, izinqubo ezintsha nezinto zokwakha ziyaqhubeka nokuphuma, ukuhlinzeka ngokusekelwa okuqinile kokuthuthuka kwayo ukusebenza.
Ensimini yesicelo, i-PCB Double-Lawer Board isetshenziswe kabanzi kuzo zonke izinhlobo zemishini ye-elekthronikhi. Kusuka ku-elekthronikhi yabathengi ezilawulweni zezimboni, kusuka kumadivayisi wezokwelapha kuya ezinhlakeni zezokuxhumana, kudlala indima ebalulekile. Ukusebenza kwayo okuzinzile nokuthembela okuhle kwenza kube yingxenye ebaluleke kakhulu yemikhiqizo yanamuhla yama-elekthronikhi. Ngasikhathi sinye, ukuguquguquka kwayo kwe-Design futhi kunikeza amathuba amaningi ezicelo ezahlukahlukene, ukufeza izidingo ezithile zezinkambu ezahlukahlukene zeBhodi.
Kodwa-ke, ngokuqamba okuqhubekayo nokuhlukaniswa kwemikhiqizo ye-elekthronikhi, izidingo ze-PCB Double-Lawer Board ziyanda. Ngokuzayo, singabheka phambili ekuboneni okuphezulu kwamabhodi aphezulu kanye namabhodi aphezulu we-PCB ephakeme ukuze ahlangabezane nezidingo zesizukulwane esisha samadivayisi we-elekthronikhi. Ukuqhekeka okuqhubekayo kobuchwepheshe bezinto ezibonakalayo kanye nenqubo yokukhiqiza kuzothuthukisa ukuthuthukiswa kwayo ekuqondeni kokusebenza okuncane nokuphezulu, ukuvula isikhala esisha sokwenza izinto ezintsha kumikhiqizo ye-elekthronikhi.
1. Ake sibe nokuqonda okujulile kwesakhiwo esithile sebhodi elithile le-PCB.
Ibhodi livame ukuhlanganisa izingqimba ezimbili zomqhubi wangaphakathi kanye nezendlalelo ezimbili zengqimba yangaphandle. Isendlalelo somxhumanisi sangaphakathi esibhekele ukuxhuma izingxenye ezahlukahlukene ze-elekthronikhi ukwakha umjikelezo, kanti ungqimba lwangaphandle lwe-substrate lusebenza njengokusekelwa nokufakelwa. Lo mklamo uvumela onjiniyela bama-elekthronikhi ukuhlela izingxenye zesifunda kalula, ngcono ukuhlanganiswa kanye nokusebenza komjikelezo.
2, inzuzo yezokwakheka ye-4-Laler PCB Board ingukusebenza kwayo okuhle kwesiginali.
Isendlalelo somxhumanisi sangaphakathi sihlukaniswe ngezinto zokufaka ngogesi, ngempumelelo ihlukanisa amazinga ahlukene wesiginali. Lokhu kusebenza kwe-Isolal Solation kubaluleke kakhulu kumadivayisi we-elekthronikhi ayinkimbinkimbi, ikakhulukazi kumava aphezulu kanye nezinhlelo zokusebenza eziphezulu ze-designess.ukunciphisa ukunqunyelwa kwangaphakathi, futhi kuqinisekiswe ukuqina kwesifunda, futhi kuqinisekiswe ukuthembeka kwemishini.
3, 4 I-Layer PCB Board Design Design nayo ilungele ukuyeka ukushisa.
Amadivaysi e-elekthronikhi akhiqiza ukushisa okuningi ngesikhathi sokusebenza, kanye nokuhlakazeka okusebenzayo kokushisa kubalulekile ukuze ulondoloze ukusebenza okujwayelekile kwemishini. Ibhodi le-PCB eli-4 Lokhu kuvumela imishini ye-elekthronikhi ukuba ilondoloze kangcono izinga lokushisa elizinzile ngesikhathi sokusebenza komthwalo omkhulu, ukunweba impilo yensiza yemishini.
I-4, ibhodi le-PCB le-PCB libuye lenze kahle ngokwemigomo ye-wiring.
Ungqimba we-conductor ongaphakathi uvumela ukwakheka okuyinkimbinkimbi ngokwengeziwe futhi okuhlanganisiwe, ukunciphisa isikhala sendawo yesifunda. Lokhu kubalulekile ekuklameni okungasindi futhi okuncane kwe-elekthronikhi yedivayisi ye-elekthronikhi. Ngasikhathi sinye, ukwakhiwa okuyinkimbinkimbi kwe-wiring futhi kunikeza amathuba okuhlanganiswa kwamamojula asebenzayo asebenzayo, ukuze idivaysi ye-elekthronikhi ingakwazi ukugcina ukusebenza okuqinile kokusebenza ngenkathi kuncane.
Isakhiwo se-4-ungqimba se-PCB Board sidlala indima ebalulekile ebunjiniyela banamuhla be-elekthronikhi, futhi idizayini yayo eyingqayizivele ehlukile ihlinzeka ngokuguquguquka, ukuqina kokusebenza kanye nokushiyeka kokushisa kwamadivayisi we-elekthronikhi, okwenza kube kuhle ngezicelo ezahlukahlukene. Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe, singalindela amabhodi ama-PCB angqimba ama-4
Ithathwe ndawonye, ibhodi le-PCB elihlukene njengengxenye ebalulekile kubuchwepheshe banamuhla be-elekthronikhi, ukwakheka kwalo nokukhiqiza kubalulekile. Esigabeni sokuklanywa kwesifunda, ubunzima nobuningi besifunda kufanele bubhekwe. Esigabeni sokukhiqiza, kuyadingeka ukusebenzisa izinqubo ezithuthukile nobuchwepheshe bese ukhetha izinto ezifanele. Uhla lwayo olubanzi lwezinhlelo luhlanganisa izinkambu eziningi ezinjengezokuxhumana, amakhompyutha, kanye nezimoto, ukuhlinzeka isisekelo esiqinile sokusebenza kanye nokwethenjwa kwamadivayisi ahlukahlukene kagesi. Ngokuzayo, ukuthuthukiswa okuqhubekayo kobuchwepheshe bama-elekthronikhi, ukwakhiwa kwalo kanye nokukhiqiza kuzoqhubeka nokubhekana nezinselelo ezintsha, kepha kuzonikeza futhi indawo ebanzi yokuthuthukiswa kwamadivayisi kagesi.
