Ku-PCB, i-nickel isetshenziswa njenge-substrate enamathela ezinsimbi eziyigugu neziyisisekelo.Amadiphozithi e-nickel e-PCB ane-stress low-stress ngokuvamile ahlanganiswe nezisombululo ze-Watt nickel plating eziguquliwe kanye nezinye izixazululo ze-sulfamate nickel plating ezinezithasiselo ezinciphisa ingcindezi.Vumela abakhiqizi abangochwepheshe bakuhlaziyele ukuthi yiziphi izinkinga isisombululo se-PCB nickel plating esivame ukuhlangana nazo uma usisebenzisa?
1. Inqubo ye-nickel.Ngokushisa okuhlukile, izinga lokushisa lokugeza elisetshenzisiwe nalo lihlukile.Kusixazululo se-nickel plating esinezinga lokushisa eliphakeme, ungqimba lwe-nickel plating olutholiwe lunengcindezi ephansi yangaphakathi kanye ne-ductility enhle.Ukushisa okujwayelekile kokusebenza kugcinwa ku-55 ~ 60 degrees.Uma izinga lokushisa liphezulu kakhulu, i-nickel saline hydrolysis izokwenzeka, okuholela emigodini yokugqoka futhi ngesikhathi esifanayo kunciphisa i-cathode polarization.
2. PH inani.Inani le-PH le-electrolyte e-nickel-plated linethonya elikhulu ekusebenzeni kokumboza nokusebenza kwe-electrolyte.Ngokuvamile, inani le-pH le-nickel plating electrolyte ye-PCB ligcinwa liphakathi kuka-3 no-4. Isixazululo se-nickel sokucwenga esinevelu ye-PH ephakeme sinamandla okuhlakazeka aphezulu kanye nokusebenza kahle kwamanje kwe-cathode.Kodwa i-PH iphakeme kakhulu, ngoba i-cathode ishintsha ngokuqhubekayo i-hydrogen phakathi nenqubo ye-electroplating, uma ingaphezu kuka-6, izobangela izimbobo ongqimbeni lokucwenga.Isixazululo se-nickel plating esine-PH ephansi sinokuncibilika kwe-anode okungcono futhi singakhuphula okuqukethwe kukasawoti we-nickel ku-electrolyte.Kodwa-ke, uma i-pH iphansi kakhulu, izinga lokushisa lokuthola ungqimba olukhanyayo luzoncishiswa.Ukwengeza i-nickel carbonate noma i-basic nickel carbonate kukhulisa inani le-PH;ukwengeza i-sulfamic acid noma i-sulfuric acid kunciphisa inani le-pH, futhi kuhlola futhi kulungise inani le-PH njalo ngamahora amane phakathi nomsebenzi.
3. Anode.I-nickel plating yama-PCBs angabonwa okwamanje konke kusebenzisa ama-anode ancibilikayo, futhi kuvame kakhulu ukusebenzisa obhasikidi be-titanium njengama-anode e-engeli ye-nickel yangaphakathi.Ubhasikidi we-titanium kufanele ufakwe esikhwameni se-anode esilukwe nge-polypropylene ukuvimbela udaka lwe-anode ukuthi lungangeni ekhambi lokucwenga, futhi kufanele luhlanzwe njalo futhi lubhekwe ukuthi i-eyelet ibushelelezi yini.
4. Ukuhlanzwa.Uma kukhona ukungcoliswa kwemvelo kusisombululo sokucwenga, kufanele siphathwe ngekhabhoni ecushiwe.Kodwa le ndlela ngokuvamile isusa ingxenye ye-ejenti yokunciphisa ukucindezeleka (i-additive), okumele yengezwe.
5. Ukuhlaziya.Isixazululo se-plating kufanele sisebenzise amaphuzu ayinhloko wemithethonqubo yenqubo echazwe ekulawuleni inqubo.Hlaziya ngezikhathi ezithile ukwakheka kwesisombululo sokucwenga kanye nokuhlolwa kweseli ye-Hull, futhi uqondise umnyango wokukhiqiza ukuze ulungise amapharamitha esixazululo sokucwenga ngokuya ngemingcele etholiwe.
6. Ukunyakazisa.Inqubo ye-nickel plating iyafana nezinye izinqubo ze-electroplating.Inhloso yokushukumisa iwukusheshisa inqubo yokudlulisa ngobuningi ukuze kuncishiswe ushintsho lokugxilisa ingqondo nokwandisa umkhawulo ongaphezulu wokuminyana ovunyelwe wamanje.Kuphinde kube nomphumela obaluleke kakhulu wokunyakazisa isixazululo se-plating, okuwukunciphisa noma ukuvimbela izimbobo kungqimba lwe-nickel plating.Umoya ocindezelwe ovame ukusetshenziswa, ukunyakaza kwe-cathode kanye nokujikeleza okuphoqelekile (okuhlanganiswe ne-carbon core kanye ne-cotton core filtration) eshukumisayo.
7. Ukuminyana kwamanje kwe-Cathode.Ukuminyana kwamanje kwe-Cathode kunomthelela ekusebenzeni kahle kwamanje kwe-cathode, izinga lokubeka kanye nekhwalithi yokunamathela.Uma usebenzisa i-electrolyte ene-PH ephansi ye-nickel plating, endaweni ephansi ye-density yamanje, ukusebenza kahle kwamanje kwe-cathode kuyanda ngokukhula kwamanje kwamanje;endaweni ephakeme yamanje, ukusebenza kahle kwamanje kwe-cathode kuzimele kumthamo wamanje;ngenkathi usebenzisa i-PH ephakeme Lapho i-electroplating liquid nickel, ubudlelwano phakathi kokusebenza kahle kwamanje kwe-cathode kanye nokuminyana kwamanje abubalulekile.Njengezinye izinhlobo ze-plating, ububanzi be-cathode yamanje ekhethiwe ukuze kufakwe i-nickel kufanele futhi kuncike ekubunjweni, izinga lokushisa kanye nezimo ezinyakazayo zesisombululo sokucwenga.
