Kwihlabathi elibanzi lombane, isishunqulelo sePCB sisoloko sisetyenziselwa ukubhekisa kwibhodi yesekethe eprintiweyo.Nangona kunjalo, kwabo bangaqhelananga nobugocigoci bobu bugcisa bubalulekileyo, isigama sinokubhida kwaye sisoloko siphakamisa imibuzo efana nothi “ithetha ukuthini iPCB?”Ukuba uzifumana unomdla malunga neePCBs kwaye ufuna ukufumana ukuqonda okucacileyo kweziseko zazo, ukwindawo elungileyo.Le bhlog ijolise ekuboneleleni ngokulula ukuqonda ingcaciso malunga PCBs, ukubaluleka kwazo kunye nokusetyenziswa kwazo kwihlabathi lanamhlanje zobuchwepheshe.
Chaza iPCB
Iibhodi zesekethe eziprintiweyo (PCBs) zizinto ezibalulekileyo kwii-electronics zale mihla.Ziqulathe amashiti asicaba ezinto ezingaqhubekiyo ezifana nefiberglass esebenza njengesiseko sokunyuswa kwezinto ezahlukeneyo ze-elektroniki.La macandelo adityaniswe ngothungelwano lweengoma zobhedu, ezibizwa ngokuba yimizila, ezifakwe kumphezulu webhodi.
1. Isakhiwo kunye nomsebenzi
Eyona njongo iphambili yePCB kukubonelela ngenkxaso yoomatshini kunye noqhagamshelo lombane phakathi kwamalungu e-elektroniki.Inoxanduva lokuqinisekisa unxibelelwano oluchanekileyo kunye nonxibelelwano phakathi kwamacandelo ahlukeneyo, kubandakanywa iisekethe ezidibeneyo (ICs), i-resistors, i-transistors, i-capacitors, kunye nokunye.Iipateni zomkhondo okuqhubayo kwiibhodi zeesekethe zinceda ukwenza lula ukuhamba kombane ukuze izixhobo zombane zisebenze ngokufanelekileyo.
2. Izinto ezilungileyo zePCB
Ukudibanisa ii-PCB kwizixhobo zombane kuneengenelo ezininzi.Okokuqala, uyilo lwabo oludityanisiweyo lwenza ukuba i-miniaturization incinci, ikhulisa indawo ngaphakathi kwezixhobo zombane.Ukongeza, ukusebenzisa i-PCB kwakhona kunciphisa ithuba leempazamo ngexesha lendibano, njengoko amacandelo abekwe ngobuchule ebhodini, eyenza lula inkqubo yokuvelisa.IiPCB zikwabonelela ngokuqina okukhulu xa kuthelekiswa nezinye iindlela zocingo.Amacandelo athengiswayo aqinisekisa uxhulumaniso olukhuselekileyo kunye nokunciphisa umngcipheko weengcingo ezikhululekile okanye ukudibanisa okungalunganga.
3. Iintlobo zeePCBs
PCBs zinokwahluka ngokuntsokotha, uyilo, kunye nenani leeleya ukuhlangabezana neemfuno zezicelo ezithile.Ezinye iintlobo eziqhelekileyo zeePCB ziquka umaleko-mnye, umaleko ophindwe kabini, kunye neePCB ezinomaleko amaninzi.I-PCB ene-single-layer inomaleko omnye wobhedu kwelinye icala, ngelixa i-PCB ephindwe kabini inemikhondo yobhedu macala omabini.I-Multilayer PCBs zibandakanya iileya ezininzi ezipakishwe kwaye ziqhagamshelwe kwimingxuma egrunjiweyo ebizwa ngokuba yi-vias, evumela inani elikhulu lamacandelo ukuba adityaniswe kwaye aphuculwe ukusebenza.
4. Inkqubo yokwenziwa kwePCB
Inkqubo yokwenziwa kwePCB ibandakanya amanyathelo amaninzi.Ekuqaleni, imilinganiselo yebhodi kunye nokwakheka kwamacandelo kuyilwe kusetyenziswa isoftware encediswa yikhompyuter (CAD).Emva kokuba uyilo lugqityiwe, ludluliselwa kwibhodi yesiphaluka ngefilimu ye-photosensitive okanye imaski yokukhusela.Iindawo zobhedu eziveziweyo zicinywa kusetyenziswa isisombululo sekhemikhali, zishiya imikhondo efunwayo.Ekugqibeleni, amacandelo afakwe ebhodini kwaye athengiswa, ukugqiba inkqubo yokuhlanganisana.
ukuququmbela
Isishwankathelo, iibhodi zeesekethe eziprintiweyo (i-PCBs) zidlala indima ebalulekileyo kwi-electronics, ukubonelela ngokudityaniswa kombane oyimfuneko kunye nenkxaso yomatshini kwizixhobo ezingenakubalwa.Ukuqonda iziseko zee-PCBs, kubandakanywa ubume bazo, umsebenzi, iinzuzo, kunye neenkqubo zokuvelisa, kubalulekile ekuqondeni ii-elektroniki ezinzima esidibana nazo yonke imihla.Njengoko itekhnoloji iqhubeka nokuhambela phambili, ii-PCB ngokungathandabuzekiyo ziya kuhlala zisisiseko sezinto ezintsha, eziphuhlayo ukuhlangabezana nemingeni kunye neemfuno ezintsha.
