Kwihlabathi elikhula ngokukhawuleza letekhnoloji, imfuno yezixhobo zombane ezincinci, ezikhaphukhaphu, nezinamandla ngakumbi kukhokelele kuphuhliso lweebhodi zesekethe eziprintiweyo ezininzi (PCBs).Ezi bhodi zeesekethe eziyinkimbinkimbi ziye zaba yinxalenye ebalulekileyo ye-electronics yanamhlanje, evumela ukuba benze imisebenzi enzima ngokufanelekileyo.Kule bhlog, siza kugocagoca kubugocigoci be-PCBs ezinemigangatho emininzi kwaye sixoxe ngobume bazo, izibonelelo, kunye nezicelo ezibalulekileyo kumashishini ahlukeneyo.
I-PCB ye-multilayer, njengoko igama libonisa, yenziwe ngamaleko amaninzi esekethe.Ngokungafaniyo nee-PCB ezinamacala amabini aqhelekileyo ezinokuphatha kuphela ukuntsonkotha okulinganiselweyo kwesekethe, ii-PCB ze-multilayer zinokwamkela uthungelwano olubanzi lokulandela umkhondo, uqhagamshelo, kunye namacandelo.Ziquka i-substrate material (ngokuqhelekileyo i-FR-4) kunye neengqimba ezininzi zomkhondo wobhedu ohlulwe ngamacandelo e-insulating.La maleko adityaniswe yimingxuma emincinci ebizwa ngokuba yi-vias, evumela imiqondiso kunye namandla ukuba aqukuqelele phakathi kwamaleko ahlukeneyo.
Izinto eziluncedo kwi-PCB yamanqanaba amaninzi:
Indibaniselwano yeeleya ezininzi kuyilo lwePCB ibonelela ngeenzuzo ezininzi.Okokuqala, iiPCB zamanqanaba amaninzi zivumela ukuxinana kwesekethe ephezulu, zizenze zilungele izixhobo zombane ezihlangeneyo ezinjengee-smartphones, iilaptops, kunye nezinto ezinxitywayo.Ukongezelela, babonelela ngolawulo olungcono lwe-impedance, ukunciphisa ukuphazamiseka kunye nokuphucula imfezeko yesignali.Ii-PCB ze-Multilayer nazo zineempawu eziphuculweyo zokulahla ubushushu ngenxa yendawo yazo enkulu yomphezulu, enegalelo ekupholiseni okusebenzayo kwamacandelo.Ukongeza, babonisa ukuhambelana okuphuculweyo kwe-electromagnetic (EMC), ukunciphisa amandla e-crosstalk kunye nokuqinisekisa ukusebenza okuthembekileyo.
Usetyenziso lwePCB enemigangatho emininzi:
Ngenxa yokuguquguquka kwayo kunye neenzuzo ezininzi, iiPCB ezininzi zisetyenziswa kakhulu kwiinkalo ezahlukeneyo.Kushishino lweemoto, zisetyenziswa kwiinkqubo zoncedo lwabaqhubi (ADAS), iiyunithi zokulawula injini (ECUs) kunye neenkqubo zolwazi.I-aerospace kunye necandelo lezokhuselo lixhomekeke kwii-PCB ezininzi ukuphumeza iinkqubo zonxibelelwano, iirada kunye neenkqubo zokuhamba.Kwicandelo lezonyango, zisetyenziselwa izixhobo ezifana noomatshini be-MRI, izikena ze-ultrasound kunye nezixhobo zokubeka iliso kwisigulane.Ukongeza, ii-PCB zamanqanaba amaninzi zibalulekile kwimizi-mveliso ezenzekelayo, iinkqubo zamandla avuselelekayo, kunye ne-elektroniki yabathengi.
Imbono yekamva kunye nesiphelo:
Njengoko itekhnoloji iqhubela phambili ngesantya esingazange sibonwe ngaphambili, iiPCB zamanqanaba amaninzi ziye zaba yinxalenye yelizwe le-elektroniki.Njengoko imfuno ye-miniaturization kunye nokusebenza okuphezulu kuqhubeka nokukhula, indima yee-PCB zamanqanaba amaninzi iya kuqhubeka nokukhula.Abaphandi kunye neenjineli bayaqhubeka nokuphonononga izixhobo ezintsha kunye nobuchule bokwenza ukuqhubela phambili ukuphucula uyilo kunye nokusebenza kweePCB ezininzi.
Isishwankathelo, ii-PCB zamanqanaba amaninzi ziye zaguqula ishishini le-elektroniki ngokubonelela ngokuqina, ukusebenza okuphuculweyo, kunye nokuthembeka.Benze igalelo elibalulekileyo kuphuhliso lwezixhobo zombane ezincinci, ezisebenza ngokufanelekileyo ezibumba ubomi bethu bemihla ngemihla.Njengoko sisiya kwihlabathi elikrelekrele, eliqhagamshelwe ngakumbi, ikamva leePCB zamanqanaba amaninzi libambe amandla amakhulu okuqhubela phambili ukuqhubela phambili kwetekhnoloji.
