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.
