Ukubonelela ngefoyile yobhedu ekumgangatho ophezulu wePCB kwiinkcukacha ezahlukeneyo

Inkcazelo emfutshane:

Ifoyile yobhedu yeyona nto isetyenziswayo kwiPCB, ikakhulu isetyenziselwa ukuhambisa imiqondiso yangoku kunye neempawu. Ifoyile yobhedu kwi-PCB inokuphinda isetyenziswe njengenqwelomoya yokukhangela ukulawula uthintelo lomgca wothumelo, okanye njengomaleko okhuselayo ukucinezela ukuphazamiseka kwe-electromagnetic. Ngexesha lenkqubo yokuvelisa i-PCB, amandla okuxobula, ukusebenza kwe-etching kunye nezinye iimpawu zefoyile yobhedu nazo ziya kuchaphazela umgangatho kunye nokuthembeka kokuveliswa kwe-PCB.

Isishwankathelo

I-CNZHJ ye-copper foil ine-conductivity egqwesileyo yombane, ukucoceka okuphezulu, ukuchaneka okulungileyo, i-oxidation encinci, ukuchasana kakuhle kweekhemikhali, kunye ne-etching elula. Ngelo xesha, ukuze kuhlangatyezwane neemfuno zabathengi abahlukeneyo, i-CNZHJ inokusika i-foil yobhedu ibe ngamashidi, anokugcina abathengi abaninzi beendleko zokucubungula.

Ukutyeba kunye nobunzima befoyile yobhedu(Icatshulwe kwi-IPC-4562A)

Ubukhulu bobhedu bebhodi ye-PCB ene-copper-clad idla ngokubonakaliswa kwi-imperial ounces (oz), 1oz=28.3g, njenge-1/2oz, 3/4oz, 1oz, 2oz. Umzekelo, ubunzima bommandla we-1oz/ft² bulingana ne-305 g/㎡ kwiiyunithi zemetric. , iguqulelwe kukuxinana kobhedu (8.93 g/cm²), ilingana nobunzima be-34.3um.

Inkcazo ye-foil yobhedu "1/1": i-foil yobhedu enendawo ye-square ye-square kunye nobunzima be-ounce; sasaza i-1 yobhedu ngokulinganayo kwisitya kunye nommandla we-square foot.

c-umfanekiso

Ukuhlelwa kwefoyile yobhedu:

☞ED, i-Electrodeposited copper foil (i-ED copper foil), ibhekisa kwifoyile yobhedu eyenziwe nge-electrodeposition. Inkqubo yokuvelisa yinkqubo ye-electrolysis. Izixhobo ze-Electrolysis ngokuqhelekileyo zisebenzisa i-roller yomhlaba eyenziwe nge-titanium njenge-roller ye-cathode, i-alloy ephezulu e-soluble-based alloy okanye i-titanium-based-corrosion-resistant-resistant coating njenge-anode, kunye ne-asidi ye-sulfuric yongezwa phakathi kwe-cathode kunye ne-anode. I-electrolyte yobhedu, phantsi kwesenzo sangoku ngokuthe ngqo, ine-ion zetsimbi ezibhengezwe kwi-cathode roller ukwenza i-electrolytic original foil. Njengoko i-cathode roller iqhubeka nokujikeleza, i-foil yasekuqaleni eyenziwe ibhengezwa ngokuqhubekayo kwaye ihlulwe kwi-roller. Emva koko iyahlanjwa, yomiswe, ize ifakwe kumqulu wefoyile ekrwada. Ukucoceka kwefoyile yobhedu yi-99.8%.
☞RA, ifoyile yobhedu eqengqelekisiweyo, itsalwa kwintsimbi ekrwada yobhedu ukuze kuveliswe ubhedu olunamadyungudyungu, olunyibilikiswa, lusetyenzwe, lucocwe ngokwe-electrolytically, lwenziwe lwayiingots zobhedu malunga ne-2mm ubukhulu. I-ingot yobhedu isetyenziswe njengento esisiseko, ekhethiweyo, ihlanjululwe, kwaye ishushu-ifakwe kwaye iqhutywe (kwicala elide) kumaqondo okushisa angaphezu kwama-800 ° C ngamaxesha amaninzi. Ubunyulu 99.9%.
☞HTE, ubushushu obuphezulu bobude be-electrodeposited copper foil, yifoyile yobhedu egcina ubude obugqwesileyo kumaqondo obushushu aphezulu (180°C). Phakathi kwazo, ukunyuswa kwefoyile yobhedu kunye nobukhulu be-35μm kunye ne-70μm kubushushu obuphezulu (180℃) kufuneka kugcinwe ngaphezu kwe-30% yobude kwiqondo lokushisa. Ikwabizwa ngokuba yi-HD copper foil (i-high ductility copper foil).
☞DST, ifoyile yobhedu enecala eliphindwe kabini, irhabaxa zombini iindawo ezigudileyo nezirhabaxa. Eyona njongo yangoku kukunciphisa iindleko. Ukurhangqa umphezulu ogudileyo kunokonga unyango lomphezulu wobhedu kunye namanyathelo amdaka phambi kokuba unyibilike. Ingasetyenziselwa njengomaleko wangaphakathi wefoyile yobhedu kwiibhodi ezinamanqwanqwa amaninzi, kwaye akufuneki ukuba ibe mnyama (imnyama) ngaphambi kokuba i-laminating iibhodi ezininzi. Ukungalungi kukuba umphezulu wobhedu awufanele ukrwelwe, kwaye kunzima ukuwususa ukuba kukho ukungcola. Okwangoku, ukusetyenziswa kwe-foil ye-copper ephethwe ngamacala amabini iyancipha ngokuthe ngcembe.
☞UTF, ifoyile yobhedu ecekeceke kakhulu, ibhekisa kwifoyile yobhedu enobunzima obungaphantsi kwe-12μm. Ezona zixhaphakileyo ziifoyile zobhedu ezingaphantsi kwe-9μm, ezisetyenziswa kwiibhodi zeesekethe eziprintiweyo ukwenza iisekethe ezilungileyo. Ngenxa yokuba ifoyile yobhedu ebhityileyo kakhulu kunzima ukuyiphatha, ngokuqhelekileyo ixhaswa ngumthwali. Iintlobo zokuthwala ziquka i-foil yobhedu, i-aluminium foil, ifilimu yezinto eziphilayo, njl.
