Ukukhiqizwa wesifunda amabhodi ephrintiwe ekhaya: izici inqubo

Ukukhiqizwa wesifunda amabhodi ephrintiwe ekhaya kungenzeka. Nokho, lokhu kudinga ezithile endaweni, imishini kanye nesikhathi. Inzuzo kwalesi sakhi wukuthi imisakazo usebenza enokwethenjelwa futhi kahle.

Ukulungiselela: ukukhethwa izinto

Ukukhiqizwa wesifunda amabhodi ephrintiwe ekhaya iqala ukuqoqwa izakhi ezidingekayo. Uzodinga:

• ikhompyutha ne -printer laser (omnyama nomhlophe);
• isithombe ephepheni;
• ngamaketanga futhi nokunamathisela ngomthofu;
• amanzi, ecucuza, yensimbi chloride, acetone, ithini;
• emaceleni (sohlangothi olulodwa) PCB, futhi ubuso bawo kufanele ibe enamathela zethusi.

Lapho zonke izingxenye ababuthelwa, ungaqala womshini wesifunda amabhodi ephrintiwe ekhaya. Okokuqala kufanele udwebe circuit. Ngenxa yale njongo kakhulu elula ihluzo umhleli, nakuba ungathola eziklanyelwe ukulandelela amabhodi hlelo. Kuleli qophelo une lokunquma amabhlogo umsebenzi. Uma wesifunda idwetshwa, kumele ezinyathelisiwe. Vele khumbula ukuthi kufanele kube esibukweni.

Inqubo eceba ebhodini

Kulesi sigaba, isithombe kufanele usetshenziswe kobuso isici ngayo. Endaweni lapho isithombe is hhayi wanyathela, kwagxila elula amakhemikhali reagents. wena kuphela kudingeka bahlale ebhodini wesifunda.

Ukukhiqizwa wesifunda amabhodi ephrintiwe ekhaya kufanele kwenziwe ngokucophelela. Ngokwesibonelo, ngeke ukwazi uthinte izandla yesithombe ezinyathelisiwe. Futhi banake ebusweni ucwecwe: nakanjani kube ihlanzekile ngangokunokwenzeka. Uma ubona ukuthi kulandelwa namachibi, zama ukuxazulula ke usebenzisa lokukhuhla esihle. Ngokwemvelo, kuyinto efiselekayo degrease ebusweni nge acetone noma omunye kuphela. Ngemva ukwelashwa, zama ukungazivezi uthinte PCB.

Manje lengqondo ufuna ukudlulisa kwamanzi lelungiselelwe. Ngenxa yalesi Ipheshana isicelo ngokucophelela PCB futhi ironed yensimbi, eliwu lokushisa esiphezulu. Isithombe ngesikhathi esifanayo akufanele ukuhambisa noma kunjalo. Le nqubo ihlala kwamaminithi ambalwa, kuze amahlamvu phuzi.

Manje udinga ukubeka ikhadi esikhathini esizayo amanzi iphepha ngokweqile ofakwe futhi kusheshe ukuhlanza off. Uma isithombe ebusweni PCB ukuthola qualitatively futhi kunembile, ungakwazi dlulelani esinyathelweni esilandelayo.

inqubo etching

Ukuze sibalo kwakusekelwe ngokuqinile sihleli e ucwecwe yokukhiqiza inqubo wesifunda amabhodi ephrintiwe kuhilela ukusetshenziswa isixazululo of chloride ferric. Esikhundleni impahla kuboniswe lingasetshenziswa zethusi sulfate (100 amagremu ushukumisa ubhuqu 200 kasawoti ilitha lamanzi afudumele ngalinye). inqubo etching ihlala cishe imizuzu engu-15.

Phela isenzo kwezingenhla kungenziwa sposlosnut ibhodi ngamanzi ahlanzekile kanye sokuprakthiza izimbobo ezidingekayo ukuze uthole imininingwane. Libuye efiselekayo ukuhlanza ebusweni nge iphethini esebenzisa lokukhuhla. Ngendlela efanayo-ke wenza i-ukukhiqizwa wesifunda amabhodi multilayer ephrintiwe.

Ukuze umkhiqizo kwaba yobuhle ngaphezulu, nihlela iziqondiso. Ngenxa yale njongo isixazululo ethize, kulo ebhodini. Emva ekucubunguleni babashayeli esiliva ukuthola umbala.
