Kwi-electronics, ibhodi yesekethe eprintiweyo (PCB) ngumqolo wezixhobo ezininzi zombane.Ngelixa ukuveliswa kwee-PCB eziphucukileyo kuqhele ukwenziwa ziingcali, ukwenza ii-PCB ezinamacala amabini ekhaya kunokuba lukhetho olusebenzayo nolusebenzayo kwezinye iimeko.Kule bhlog, siza kuxoxa ngenyathelo ngenyathelo lenkqubo yokwenza iPCB enamacala amabini kubuntofontofo bekhaya lakho.
1. Qokelela imathiriyeli efunekayo:
Ngaphambi kokuntywila kwinkqubo yokuvelisa, kubalulekile ukuqokelela zonke izinto eziyimfuneko.Ezi ziquka iilaminayithi ezigqunywe ngobhedu, iziphawuli ezisisigxina, izishicileli zelaser, iferric chloride, i-acetone, i-drill bits, i-copper-plated wire, kunye nezixhobo zokhuseleko ezifana neeglavu kunye neeglavu.
2. Yila uyilo lwePCB:
Usebenzisa isoftware yoyilo yePCB, yenza iskimu sesekethe ye-elektroniki ofuna ukuyakha.Emva kokuba iskimu sigqityiwe, yila uyilo lwePCB, ubeke amacandelo ahlukeneyo kunye nemikhondo njengoko kufuneka.Qinisekisa ukuba uyilo lufanelekile kwiPCB enamacala amabini.
3. Shicilela uyilo lwePCB:
Shicilela uyilo lwePCB kwiphepha elimenyezelayo usebenzisa iprinta yelaser.Qinisekisa ukuba ujonga umfanekiso ngokuthe tye ukuze udluliselwe ngokuchanekileyo kwibhodi enentsimbi yobhedu.
4. Uyilo losasazo:
Sika i-layout eprintiweyo kwaye uyibeke ijonge phantsi kwibhodi yobhedu.Yikhusele kwindawo kunye ne-tape kwaye uyitshise ngentsimbi ngokushisa okuphezulu.Cinezela ngokuqinileyo malunga nemizuzu eyi-10 ukuqinisekisa ukusabalalisa ubushushu.Oku kuya kudlulisela inki ukusuka kwiphepha ukuya kwipleyiti yobhedu.
5. Etching plate:
Susa ngokucophelela iphepha kwibhodi yeentsimbi.Ngoku uyakubona uyilo lwePCB lukhutshelwe kumphezulu wobhedu.Galela i-ferric chloride eyaneleyo kwiplastiki okanye kwisitya seglasi.Gxuma ibhodi kwisisombululo se-ferric chloride, uqinisekise ukuba ihlanganiswe ngokupheleleyo.Gqugquzela ngobumnene isisombululo ukukhawulezisa inkqubo etching.Khumbula ukunxiba iiglavu kunye neglavu ngeli nyathelo.
6. Coca kwaye uhlole ibhodi yesekethe:
Emva kokuba inkqubo ye-etching igqityiwe, ibhodi iyasuswa kwisisombululo kwaye ihlanjwe ngamanzi abandayo.Sika imiphetho kwaye ukhuhle ngobunono ibhodi ngesipontshi ukususa inki engaphezulu kunye nentsalela ye-etch.Yomisa ibhodi ngokupheleleyo kwaye ujonge naziphi na iimpazamo okanye iingxaki ezinokubakho.
7. Ukugrumba:
Ukusebenzisa i-drill enentwana encinci, gqobhoza ngononophelo imingxuma kwi-PCB kwiindawo ezichongiweyo zokubekwa kwecandelo kunye ne-soldering.Qinisekisa ukuba umngxuma ucocekile kwaye awunayo nayiphi na inkunkuma yobhedu.
8. Amacandelo e-Welding:
Beka izinto zombane kumacala omabini ePCB kwaye uzikhusele ngeziqeshana.Sebenzisa intsimbi ye-soldering kunye ne-solder wire ukudibanisa amacandelo kwiimpawu zobhedu.Thatha ixesha lakho kwaye uqinisekise ukuba ii-solder joints zicocekile kwaye ziqinile.
ukuququmbela:
Ngokulandela le miyalelo inyathelo nenyathelo, ungenza ngempumelelo PCB-macala amabini ekhaya.Ngelixa inkqubo inokuqala ukubandakanya uvavanyo kunye nempazamo, ngokuziqhelanisa kunye nengqalelo kwiinkcukacha, unokufikelela kwiziphumo zobungcali.Khumbula ukuhlala ubeka ukhuseleko kwindawo yokuqala, nxiba izixhobo ezifanelekileyo zokukhusela kwaye usebenze kwindawo engena umoya.Ke vula ubuchule bakho kwaye uqalise ukwakha iiPCB zakho ezinamacala amabini!
