I-cire ye-PCB yobhedu iwela (idla ngokubizwa ngokuba ngu-nqabela ubhedu). Iifektri ze-PCB zonke zithi zonke ziyingxaki ye-lamite kwaye ifuna iifektri zabo zokuvelisa ukuthwala ilahleko embi.
1. I-foil yobhedu igqithile. I-moild ye-electrolytic yobhedu esetyenziswe kwimarike yeyona ndawo isetyenzisiweyo engatshatanga (eyaziwa ngokuba yi-biling tiil) kunye nepali ebomvu (eyaziwa ngokuba yi-foil ebomvu). Ngokuqhelekileyo kobhedusi ojijekileyo ngokubanzi ubhedu becala ngaphezulu kwe-77im foil, i-foil ebomvu kunye ne-ash foil engaphantsi kwe-18m ngokusisiseko saliwe. Xa uyilo lwesekethe lwabathengi lungcono kunomgca we-etching, ukuba inkcazo yobhedu itshintshiwe kodwa iiparamitha ze-enkper zihlala zingaguqukanga, ixesha lokuhlala le-setper foil lide kakhulu. Kuba i-zinc ikwisinyithi esisebenzayo, xa ucingo lobhedu kwi-PCB luyelwe kwisisombululo se-etching ixesha elide, iya kukhokelela ekubuyiseleni icala le-zinc, ebangela ukuba iphendulwe i-chinc ecekeceke kwaye yahlulwe kwi-substrate. Oko kukuthi, ucingo lobhedu luyawela. Enye imeko kukuba akukho ngxaki kunye neparamitha yokuphumeza i-PCB, kodwa emva kokuba i-etching ihlanjwe ngamanzi kunye nokusoma okungalunganga, ucingo lobhedu lujikelezwe sisisombululo se-etching ye-etchi. Ukuba ayijongiswanga ixesha elide, iya kubangela i-etching ye-etching yecala lobhedu. Phosa ubhedu. Le meko ibonakaliswa njengokugxila kwimigca emincinci, okanye ngexesha lemozulu enomswakama, iziphene ziya kuvela kwi-PCB iyonke. Shonga ucingo lobhedu ukuze ubone ukuba umbala womphezulu woqhakamshelwano kunye nomaleko wesiseko (obizwa ngokuba yi-rousched) itshintshiwe. Umbala we-foil yobhedu yahlukile kwi-foil eqhelekileyo yobhedu. Umbala wobhedu wobhedu olwenziwe ngumaleko ongezantsi, kunye namandla aphendukayo ye-foil yobhedu
2. Ukungqubana kwenzeka ekuhlaleni kwinkqubo ye-PCB, kwaye ucingo lobhedu lwahlulwe kwibala lamandla angaphandle. Oku kusebenza kakubi kukuma kakubi okanye ukuqhelaniswa nezifundo. Ucingo lobhedu olulahliweyo luya kuba nokujija okubonakalayo okanye ukukrala / amanqaku empembelelo kwicala elinye. Ukuba ukhalise ucingo lobhedu kwilungu elineziphene kwaye ujonge umphezulu we-foil yobhedu, unokubona ukuba umbala we-foil yobhedu buyeyona nto iqhelekileyo, kwaye amandla e-Peel ye-foil iqhelekile.
3. Uyilo lwesekethe lwe-PCB alunangqondo. Ukuba i-foil emdaka yobhedu isetyenziselwa ukuyila isekethe ecekeceke kakhulu, iya kubangela ukwaliwa kwesekethe kunye nobhedu.
I-2. Izizathu zeWamote Demote:
Phantsi kweemeko eziqhelekileyo, okoko nje i-lamote ishushu icinezelwe ngaphezulu kwemizuzu engama-30, i-foil yobhedu kunye ne-Presrere iya kudityaniswa ngokupheleleyo, ngoko ke i-cinezela ayiyi kuchaphazela i-foil yobhedu. Nangona kunjalo, kwinkqubo yokufaka kunye nokufaka i-PP, ukuba i-PP ingcolisekile okanye i-foil yobhedu phakathi kwe-foil yobhedu i-foil kunye ne-Poel ye-Poel ye-Poel ye-Poel ye-Poel ye-fooper kufutshane.
I-3. Izizathu zezinto eziluhlaza
1. Njengoko sele kuchaziwe apha ngasentla, i-elektrolytic yobheduzo ye-electrolytic ziimveliso ezizeziwe okanye ze-copper. Ukuba i-piak ingaqhelekanga ngexesha lokuveliswa koboya, okanye ngexesha lokubekwa kwe-GARvaning / ukubekwa kobhedu, amasebe e-crystal babi, ebangela ukuba ubhedu lube ngamandla aphezulu akwanele. Xa i-foil embi ye-foil icinezelwe i-PCB i-PCB kunye neplagi kwi-elektroniki umzi-mveliso, ucingo lobhedu luya kuwa ngenxa yefuthe lamandla angaphandle. Olu hlobo lokungafunwa kobhedu aluyi kubangeli i-Porposion yecala elibonakalayo emva kokwenza ucingo lobhedu ukuze lubone umphezulu wobhedu lwe foil yobhedu
2. Ukulungelelaniswa okungalunganga kwe-copper foil kunye ne-resin: amanye amaqela anepropathi ekhethekileyo, anje ngamaphepha e-HTG, asetyenziswa ngoku ngenxa yeenkqubo ezahlukeneyo ze-resin. I-Arhente yokunyanga isetyenzisiwe i-PN RSIn, kwaye i-resin molecular ye-molecular ilula. Inqanaba lokucofa inqamleza, kwaye kuyimfuneko ukusebenzisa i-foil yobhedu ngencam ekhethekileyo ukuyingqinelana nayo. Xa ivelisa imizuzu, ukusetyenziswa kwe-foil yobhedu akuthengisi inkqubo ye-resin, kukhokelela kumandla awonekiweyo kwephepha lephepha lesinyithi-cled fiel, kunye nokufakwa kocingo lwe-with kunye ne-wire ye-wire ye-wire ye-wire.
