Amabhodi esekethe aphrintiwe (ama-PCB) avame ukunganakwa emhlabeni wobuchwepheshe besimanje, kodwa adlala indima ebalulekile cishe kuzo zonke izisetshenziswa zikagesi esizisebenzisayo namuhla.Kungakhathaliseki ukuthi i-smartphone yakho, ikhompuyutha ephathekayo, noma izinto zikagesi ezihlakaniphile ezisekhaya lakho, ama-PCB amaqhawe angacushiwe enza lawa madivayisi asebenze ngaphandle komthungo.Kule bhulogi, sizongena emhlabeni wama-PCB, sithole ukuthi ayini nokuthi asebenza kanjani.
Umzimba:
1. Ulwazi oluyisisekelo lwe-PCB
Ibhodi lesifunda eliphrintiwe (PCB) ishidi elincanyana le-insulating material (imvamisa i-fiberglass) elinemikhondo yensimbi ehambayo eqoshwe kulo.Lawa mathrekhi asebenza njengemigudu yokuxhumana yamasignali kagesi phakathi kwezingxenye ze-elekthronikhi.Usayizi, ubunkimbinkimbi kanye nenani lezendlalelo ze-PCB kungahluka kuye ngezidingo zocingo.
2. Izingxenye ze-PCB
Ama-PCB akhiwe izingxenye ezihlukahlukene ezihlanganisa ukumelana, ama-capacitor, ama-diode, ama-transistors namasekethe ahlanganisiwe (ICs).Lezi zingxenye zidayiswa ku-PCB, okwenza ukuxhumana kukagesi phakathi kwazo.Ingxenye ngayinye inendima ethile kumjikelezo futhi inikela ekusebenzeni okuphelele kwedivayisi.
3. Isebenza kanjani i-PCB
I-PCB isebenza ngokuvumela amasignali kagesi ukuthi ageleze phakathi kwezingxenye ezahlukene, iqinisekise ukuthi ziyaxhumana futhi zenza imisebenzi eyabelwe.Ukulandelelwa kwensimbi ku-PCB kunikeza izindlela ezidingekayo zokudlulisa isignali.Izingxenye eziku-PCB zibekwe ngendlela ehlelekile ngokohlelo lwesekethe ukuze kuthuthukiswe ukusebenza nokunciphisa ukuphazamiseka.
4. Inqubo yokukhiqiza
Ama-PCB akhiqizwa ngochungechunge lwezinyathelo.Okokuqala, ukwakheka kwesekethe kwenziwa kusetshenziswa isoftware ye-computer-aid design (CAD).Umklamo ube usudluliselwa ku-PCB kusetshenziswa inqubo ye-photolithographic.Ibhodi libe seliqoshwa ukuze lisuse ithusi elingafunwa futhi lishiye imikhondo efunwayo kuphela.Ekugcineni, izingxenye zithengiswa ebhodini futhi zihlolwe ikhwalithi ngaphambi kokuhlanganiswa ku-electronics.
5. Izinzuzo kanye nokungalungi kwe-PCB
Ama-PCB anezinzuzo eziningi njengokuthembeka, ukubumbana, ukukhiqizwa ngobuningi kalula, nokugeleza kwesignali okusebenzayo.Kodwa-ke, futhi banemikhawulo, okuhlanganisa ukungaguquguquki, izindleko zokusetha eziphezulu zokuqala, nesidingo semishini ekhethekile yokwenza.
Isiphetho
Amabhodi esekethe aphrintiwe (ama-PCB) awumgogodla wezinto zikagesi zesimanje, avumela izisetshenziswa zethu zansuku zonke ukuthi zisebenze ngaphandle komthungo.Ukwazi ukuthi i-PCB isebenza kanjani kungathuthukisa ukwazisa kwethu ngobuchwepheshe obuyinkimbinkimbi ngemuva kwegajethi.Kusukela esakhiweni esiyisisekelo kuye kunqubo yokukhiqiza, i-PCB iyisici esibalulekile esiqhuba inqubekelaphambili yobuchwepheshe.Njengoba siqhubeka nokwamukela intuthuko emkhakheni wedijithali, ama-PCB ngokungangabazeki azoqhubeka nokuvela futhi alolonge ikusasa lezinto zikagesi.
