Ungayenza njani i-PCB esemgangathweni ophezulu? Isikhokelo esipheleleyo samanyathelo abalulekileyo okuvelisa i-PCB
Inkqubo yeMveliso yePCB
Inyathelo 1: Ukuqinisekiswa kwedatha
Ngaphambi kokuba kuveliswe, umenzi we-PCB uqinisekisa idatha yokwenza ibhodi enikwe ngumthengi, kubandakanya ubungakanani bebhodi, iimfuno zenkqubo, kunye nobungakanani bemveliso. Imveliso iqhubeka kuphela emva kokufikelela kwisivumelwano nomthengi.
Inyathelo lesi-2: Ukusika Izinto
Ngokolwazi lomthengi lokwenza iibhodi, sika iibhodi zemveliso zibe ziingceba ezincinci ezihlangabezana neemfuno. Imisebenzi ethile: izinto zepleyiti enkulu → ukusika ngokweemfuno ze-MI → ukusika ipleyiti → ukusika ikona/ukusila umphetho → ukukhupha ipleyiti.
Inyathelo lesi-3: Ukubhoboza
Gobhoza ububanzi bomngxuma obufunekayo kwiindawo ezifanelekileyo kwibhodi yePCB. Imisebenzi ethile: izinto zepleyiti enkulu → ukusika ngokweemfuno ze-MI → ukucola → ukusika ikona/ukusila umphetho → ukukhupha ipleyiti.
Inyathelo lesi-4: Ukucwila kweCopper
Umaleko omncinci wobhedu ufakwa ngeekhemikhali kumngxuma wokukhusela. Imisebenzi ethile: ukugaywa okurhabaxa → ukuxhoma ibhodi → umgca wokuntywila wobhedu ozenzekelayo → ukuthoba ibhodi → ukuyifaka kwi-1% ye-H2SO4 enyibilikisiweyo → ukwenza ubhedu lube lukhuni.
Inyathelo lesi-5: Ukudluliselwa komfanekiso
Dlulisa imifanekiso kwifilimu yokuvelisa uye ebhodini. Imisebenzi ethile: ibhodi yehemp → ukucinezela ifilimu → ukuma → ukulungelelanisa → ukuvezwa → ukuma → uphuhliso → ukuhlolwa.
Inyathelo lesi-6: Ukuplatwa kweMifanekiso
I-Electroplate yi-copper layer enobukhulu obufunekayo kunye ne-gold nickel okanye i-tin layer kwi-copper sheet eveziweyo okanye eludongeni lomngxuma we-circuit pattern. Imisebenzi ethile: ipleyiti ephezulu → ukususa amafutha → ukuhlamba ngamanzi okwesibini → ukubola okuncinci → ukuhlamba ngamanzi → ukuhlamba nge-asidi → i-copper plating → ukuhlamba ngamanzi → ukufunxa nge-asidi → i-tin plating → ukuhlamba ngamanzi → ipleyiti esezantsi.
Inyathelo lesi-7: Ukususwa kweFilimu
Susa umaleko wokugquma ochasene nombane ngesisombululo se-NaOH ukuze uveze umaleko wobhedu ongengowesekethe.
Inyathelo 8: Ukukrola
Susa iindawo ezingezizo ezesekethe nge-reagent yeekhemikhali.
Inyathelo lesi-9: Imaski yeSolder
Dlulisa imifanekiso yefilimu eluhlaza ebhodini, ikakhulu ukukhusela isekethe nokuthintela ukudityaniswa kweendawo ezine-tin kwisekethe.
Inyathelo le-10: Isikrini sesilika
Printa oonobumba ababonakalayo kwibhodi yePCB. Imisebenzi ethile: emva kokulungiswa kokugqibela kwemaski yesolder, zipholise uze ume ngxi, lungisa isikrini, printa oonobumba, uze ekugqibeleni upholise.
Inyathelo le-11: Iminwe yeGolide
Faka umaleko we-nickel/gold wobukhulu obufunekayo kumnwe weplagi ukuze womeleze ubulukhuni bawo kunye nokumelana nokuguguleka.
Inyathelo 12: Ukuyila
Hlaba imo efunekayo kumthengi usebenzisa umatshini wokubumba okanye we-CNC.
Inyathelo 13: Uvavanyo
Iziphene zokusebenza ezibangelwa ziisekethe ezivulekileyo, iisekethe ezimfutshane, njl.njl., kunzima ukuzibona ngokujonga ngamehlo kwaye zinokuvavanywa kusetyenziswa isixhobo sokuvavanya esibhabhayo.
