Iibhodi zesekethe eziprintiweyo (PCBs) zidla ngokungakhathalelwa kwihlabathi lobugcisa bezi mini, ukanti zinendima ebalulekileyo phantse kuzo zonke izixhobo ze-elektroniki esizisebenzisayo namhlanje.Nokuba yi-smartphone yakho, ilaptop, okanye izixhobo zombane ezikwikhaya lakho, iiPCB ngamagorha angaqanjwanga enza ezi zixhobo zisebenze ngaphandle komthungo.Kule bhlog, siza kungena kwihlabathi le-PCBs, sifumanise ukuba ziyintoni kwaye zisebenza njani.
Umzimba:
1. Ulwazi olusisiseko lwePCB
Ibhodi yesekethe eprintiweyo (PCB) ishidi elicekethekileyo lezinto ezigqumayo (ngokuqhelekileyo i-fiberglass) eneempawu zetsimbi eziqhutywa kuyo.Ezi ndlela zisebenza njengeendlela zokudibanisa kwiimpawu zombane phakathi kwezinto zombane.Ubungakanani, ubunzima kunye nenani leeleya zePCB zinokuhluka ngokuxhomekeke kwiimfuno zesixhobo.
2. Amacandelo ePCB
IiPCB zenziwe ngamacandelo ahlukeneyo aquka ukuxhathisa, ii-capacitors, ii-diode, ii-transistors kunye neesekethe ezidibeneyo (ICs).La macandelo athengiswa kwi-PCB, ukwenza uqhagamshelwano lombane phakathi kwabo.Icandelo ngalinye linendima ethile kwisekethe kwaye linegalelo ekusebenzeni ngokubanzi kwesixhobo.
3. Isebenza njani iPCB
I-PCB isebenza ngokuvumela imiqondiso yombane ukuba ihambe phakathi kwezinto ezahlukeneyo, iqinisekisa ukuba ziyanxibelelana kwaye zenze imisebenzi yazo.Imigca yesinyithi kwiPCB ibonelela ngeendlela eziyimfuneko zokuhanjiswa komqondiso.Amacandelo kwi-PCB abekwe ngobuchule ngokuhambelana noyilo lwesekethe ukuze kuphuculwe umsebenzi kunye nokunciphisa ukuphazamiseka.
4. Inkqubo yokuvelisa
IiPCB zenziwa ngokulandelelana kwamanyathelo.Okokuqala, uyilo lwesekethe lwenziwa kusetyenziswa isoftware encediswa yikhompyuter (CAD).Uyilo ke lugqithiselwe kwi-PCB kusetyenziswa inkqubo ye-photolithographic.Ibhodi ke ixhonywe ukususa ubhedu olungafunekiyo kwaye ishiye kuphela imikhondo efunwayo.Ekugqibeleni, amacandelo athengiswa ebhodini kwaye ahlolwe umgangatho ngaphambi kokuba ahlanganiswe kwi-electronics.
5. Izinto eziluncedo kunye nezingeloncedo kwiPCB
IiPCB zineenzuzo ezininzi ezinjengokuthembeka, ukubumbana, ukukhululeka kokuveliswa kobuninzi, kunye nokuhamba komqondiso okusebenzayo.Nangona kunjalo, bakwanazo nemida, kubandakanya ukungaguquguquki, iindleko eziphezulu zokuseta, kunye nesidingo sezixhobo ezikhethekileyo zokwenza.
Ukuqukumbela
Iibhodi zesekethe eziprintiweyo (PCBs) ziyintsika ye-electronics yanamhlanje, eyenza izixhobo zethu zemihla ngemihla zisebenze ngaphandle komthungo.Ukwazi indlela esebenza ngayo iPCB kunokwandisa uxabiso lwethu ngobuchwephesha obuntsonkothileyo obusemva kwesixhobo.Ukusuka kulwakhiwo olusisiseko ukuya kwinkqubo yokwenziwa kwemveliso, iPCB yinto ephambili eqhuba inkqubela phambili yetekhnoloji.Njengoko siqhubeka nokwamkela ukuqhubela phambili kummandla wedijithali, ii-PCB ngokungathandabuzekiyo ziya kuqhubeka nokuvela kunye nokubumba ikamva lezinto zombane.
