Njengoko iteknoloji ihambela phambili, imfuno yeebhodi zesekethe eziprintiweyo (PCBs) iyaqhubeka nokukhula. PCBs amacandelo abalulekileyo kwizixhobo zombane ezidibanisa amacandelo ahlukeneyo ukwenza iisekethe ezisebenzayo. Inkqubo yokuvelisa i-PCB ibandakanya amanyathelo amaninzi, esinye sezigaba eziphambili ku-etching, esivumela ukuba sisuse ubhedu olungeyomfuneko kumphezulu webhodi. Ngelixa izisombululo ze-etch zorhwebo zifumaneka ngokulula, unokwenza nezakho izisombululo ze-PCB ekhaya. Kule bhlog, siza kukukhokela kwinkqubo, sibonelela ngezisombululo ezingabizi kakhulu kwaye kulula ukuzisebenzisa kuzo zonke iimfuno zakho zePCB.
Impahla engekasilwa:
Ukwenza isisombululo se-PCB esenziwa ekhaya, uya kufuna ezi zithako zilandelayo:
1. I-hydrogen peroxide (3%): Into eqhelekileyo yasekhaya esebenza njenge-oxidizing agent.
2. I-Hydrochloric acid (i-hydrochloric acid): Ifumaneka kwiivenkile ezininzi ze-hardware, isetyenziselwa ukucoca.
3. Ityuwa yetafile (i-sodium chloride): Enye into eqhelekileyo yasekhaya enokuphucula inkqubo yokubhala.
4. Amanzi adibeneyo: asetyenziselwa ukuhlambulula isisombululo kunye nokugcina ukuhambelana kwayo.
inkqubo:
Ngoku, makhe singene kwinkqubo yokudala isisombululo sePCB ekhaya:
1. Ukhuseleko Kuqala: Ngaphambi kokuba uqalise, qiniseka ukuba unezixhobo zokhuseleko eziyimfuneko ezinjengeeglavu, iiglavu, kunye nendawo engena umoya. Iikhemikhali zinokuba yingozi xa zingaphathwanga kakuhle, ngoko lumke kulo lonke ixesha.
2. Umxube oxutywe: Yongeza i-100ml ye-hydrogen peroxide (3%), i-30ml i-hydrochloric acid kunye ne-15g yetyuwa kwisitya seglasi. Gxuma umxube kakuhle de ityuwa ichithwe ngokupheleleyo.
3. I-Dilution: Emva kokuxuba izisombululo eziphambili, xuba malunga ne-300 ml yamanzi adibeneyo. Eli nyathelo libalulekile ekugcineni i-etch consistency efanelekileyo.
4. Inkqubo ye-Etching: Dipha i-PCB kwisisombululo se-etching, qiniseka ukuba ifakwe ngokupheleleyo. Gqugquzela ngobunono isisombululo ngamanye amaxesha ukukhuthaza ukufana okufanayo. Ixesha le-Etch linokwahluka ngokuxhomekeke kubunzima kunye nobukhulu bemikhondo yobhedu, kodwa ngokwesiqhelo yimizuzu eli-10 ukuya kwengama-30.
5. Hlanza kwaye ucoceke: Emva kwexesha elifunekayo le-etching, susa i-PCB kwisisombululo se-etching kwaye uhlambulule ngokucokisekileyo phantsi kwamanzi asebenzayo ukumisa inkqubo ye-etching. Sebenzisa ibhrashi ethambileyo okanye isipontshi ukucoca nakuphi na ukungcola okushiyekileyo kumphezulu webhodi.
Ukwenza eyakho isisombululo se-PCB etching ekhaya ibonelela ngendlela efikelelekayo nekulula ukuyisebenzisa kwiinketho zorhwebo. Nangona kunjalo, kubalulekile ukukhumbula ukuba ukusebenza ngeekhemikhali kufuna izilumkiso ezifanelekileyo zokhuseleko. Hlala uphatha ezi zixhobo kwindawo enomoya kwaye unxibe izixhobo zokukhusela. Izisombululo zePCB ezenziwe ekhaya zenza iiprojekthi ze-elektroniki ze-DIY zibe lula ngelixa ugcina imali kwaye unciphisa inkunkuma. Ke ngoko khulula ubuchule bakho kwaye ungene kwihlabathi le-PCB etching ukusuka kubutofotofo bekhaya lakho!
