Ubuchwepheshe be-LUT: ukwakhiwa kwamabhodi wesifunda aphrintiwe

Iyini i-LUT (ubuchwepheshe be-laser-iron)? Isihloko sethu sizokhuluma ngakho.

Amapulangwe wesifunda aphrintiwe

Ukuklama kwamadivaysi e-omsakazo omsakazo kuhlobene eduze nokudalwa kwamabhodi wesifunda aphrintiwe. Uma kungekho isifiso sokuchitha isikhathi esiningi ekwenzeni kwabo, ke indlela echazwe kulesi sihloko inhle kuwe. Uma unayo ikhono elifanele, kuzokwenza kube lula ukwenza lula ukudala. Itheknoloji ye-LUT ingahlukaniswa ngezigaba ezinjalo zokukhiqiza ibhodi lesifunda eliphrintiwe:

1. Dala isithombe.
2. Senza umsebenzi wokusebenza.
3. Sidlulisela umdwebo kuwo.
4. Sifisa umsebenzi wokusebenza.
5. Sula.
6. Senza umgodi.
7. Tin plating.

Njengoba ungase uzibonele, ngokwenza umthamo we-LUT ekhaya ungabonakala ngaphandle kwezinkinga ezinkulu nezindleko. Mhlawumbe, awudingi ngisho nokuthola lutho olusha, ngoba konke okudingayo emsebenzini kungatholakala kalula ekamelweni elingemuva. Ubuchwepheshe be-LUT yamabhodi wesifunda okuphrintiwe okukhiqizwa bufanelekile ezimweni lapho kukhona ukukhiqizwa okukodwa nge-electronic amateur. Ekhuluma ngokufaneleka, okokuqala bakhumbula ngokuncishiswa, ukwethenjelwa nokulula emsebenzini. Yiqiniso, lokhu akusizo zonke izinzuzo, noma okungenhla, okungaphezulu kokwanele kobuchwepheshe be-LUT bakhetha ukukhetha, abadwebi abaningi basekhaya.

Dala isithombe

Kukhona ukukhethwa okubanzi kwezindlela: kusuka ipensela kuya ezinhlelweni ezikhethekile. Uma udala ibhodi yesifunda ephrintiwe kubalulekile ukuzama ukufeza imigomo enjalo:

1. Nciphisa inani le-jumpers.
2. Amathrekhi ahlobene komunye nomunye kufanele abe yi-perpendicular and parallel.
3. Ukufakwa okuphelele.

Lapho udala imidwebo, cabanga ngobukhulu bezinto, indawo yezindawo zokugcina zezingxenye kanye nobukhulu bawo. Kubalulekile futhi ukuba unakekele ukuthi abaqhubi be-high-current bahamba ngezindlela ezibanzi. Ukudala isithombe kungaqhathaniswa nokudlala iTetris: ungabhala izakhi ngendlela oyithandayo, uze uthola ithuba elizosiza ukuqaphela ubuchwepheshe be-LUT. Iphrinta ye-inkjet (noma i-laser) izokusiza ukuba uyenze ngokomzimba, uzizwe ngezandla zakho.

Ukwenza umsebenzi wokusebenza

Ngakho-ke, sinomdwebo, futhi singakhuluma ngobukhulu bebhodi. Manje udinga ukusika isithombe, uwugqoke kwi-textolite bese uyikhomba ngombusi. Ingabe akuyona inkimbinkimbi kangaka ye-LUT-technology? Hamba, yilokho esikudingayo! Sika eceleni kwemigqa engenalutho lwe-textolite enemibala eqoshiwe. Hlanganisa imiphetho ezungeze umjikelezo ngefayela bese uhlanza ubuso. Ukuze wenze lokhu, ungasebenzisa ipensela encane noma i-wire grater (kusuka kulabo abahlanza izitsha), kanye ne-detergent.

Sidlulisela umdwebo: ulwazi jikelele

Ake sicabange ukuthi sanyathelisa isithombe kumshicileli we-laser. Futhi manje sidinga ukuyithumela emsebenzini owenziwe ephepheni. Beka okushiwo, isithombe esithombeni. Ngisho insimbi yensimbi, kodwa ngesikhathi esifanayo isebenze umzamo obala obala. I-paper exfoliate, i-trim ne-etch. Uma ushicilela isithombe, kuyinto efiselekayo ukusetha ukukhanya okungenani ukuze isithombe esitholile kakhulu sitholakale. Kuyinto efiselekayo ukusetha ubukhulu be toner kuzilungiselelo eziphambili. Lokhu kuyadingeka ukugwema imiphumela emibi nge-lumens, okuyi-alas, ene-LUT-ubuchwepheshe. Usayizi obuncane weziphala ziyamkelwa kuphela, mhlawumbe, azikho ngaphezu kwamamitha angu-0.2.

Dlulisa umdwebo: iphepha

Lokhu kuyinto encane, ngakho-ke kuyadingeka ukuyifinyelela ngomthwalo wemfanelo. Yikuphi amasampula okungcono okubonwa ngeteknoloji ye-LUT? Leli phepha kumele libe likhulu, ungathatha iphepha eliphekiwe. Ungathinti iminwe ye-fat. Akudingekile ukuthenga iphepha eliboshwe - ungathatha incwajana yokukhangisa. Into eyinhloko ukuthi imhlophe ngakolunye uhlangothi. Uma kungenzeka, kungcono ukubeka amakhophi amabili amabhodi wesifunda aphrintiwe. Sika futhi ugqoke emshini wokusebenza ukuze iphethini lihlangothini lwesilwane. Sithatha insimbi ejwayelekile, asisebenzisi isobho. Kungcono ukusetha ukushisa okujwayelekile. Sibamba ingxenye yomdwebo ukuze ingashiyi emsebenzini. Qala ngokushelela kahle isithombe, kodwa ungawuvumeli ukuba ushintshe. Futhi ungadluli ngamandla: uma ucindezela kanzima, i-toner izokhipha, futhi nayo imathrekhi. Lokhu kungenzeka futhi uma insimbi ishisa kakhulu. Uma izingxenye zomsebenzi wokusebenza ziye zacutshungulwa kahle, awukwazi ukubushelela kahle i-toner kuyo. Uma konke sekulungele, umsebenzi wokusebenza kufanele uphole phansi. Bese ubeka esitsheni ngamanzi afudumele. Engeza isipuni se-acetic acid. Leli phepha lizothambisa futhi liqale ukuqhuma. Ngemizuzu engaba yishumi, izokwehla ngemuva kwe-toner. Hlanganisa isithombe esiphezulu nge-jet yamanzi. Okokuqala, kungenzeka kube nezimpumputhe ngabanye, kodwa uma usebenza ngesimo sesibili sohlolo kumele kube ngokwanele ukuwagwema. Ngokuvamile, ubuchwepheshe be-LUT bokukhiqiza amabhodi wesifunda okuphrintiwe kungabonakala buyinkimbinkimbi, kodwa kuqala kuphela. Ngendlela, kunconywa ukuthi kube namaphepha amabili ngenhla kulesi sihloko, futhi lokhu akuyona ingozi. Ngesikhathi sokuqala oshayina abaqalayo benza amaphutha amancane, okuba yi-toner enezinhlamvu kanye nezinye izinhlawulo. Ukuze wenze ibhodi lesifunda lekhwalithi ephakeme, futhi kunconywa ukuba ulungiselele okunye.

Kuthiwani uma kungekho iphrinta laser?

Ungasebenzisa umakaki unomphela. Futhi kulezi zinhloso, futhi kufanelekile nge-nail polish, esetshenziswa ngombala omncane. Ngokuvamile, ungenza okungenani ipensela kanye ne-eraser eyodwa. Kusetshenziswa kulezi zimo ubuchwepheshe be-LUT ngokusetshenziswa kweglue ngemiphumela engcono. Uma ugeza izinsalela zayo ngamanzi, qinisekisa ukuthi akasahlali ngempela. Futhi, uma ugoba izimbobo, qiniseka ukuthi iziphetho ezikuzo zizozizwa zihle.

Ukumisa umsebenzi

Ukwenza lokhu, sebenzisa i-chloride ye-ferric. Uma uthenga into, qiniseka ukuthi ifomu le-powder. I-chlorine yensimbi enjalo ifaneleka kakhulu ngezinhloso zethu. Nakuba ukusetshenziswa kwesinhlanganisela setafula usawoti nethusi le-sulfate akukhipha. Kodwa lapha kudingekile ukuba uqaphele ukulinganisela okuthile. Ngakho-ke, ilitha elilodwa lamanzi abilisiwe kufanele athathe amagremu angamakhulu amabili amavitriol bese engeza usawoti kuze kube yilapho eseqedwa. Isisombululo esilandelayo kufanele sihlungwe. Uma kushisa ukushisa kwama-degrees Celsius angu-50, khona-ke ithusi lithatha imizuzu engu-15-20 ukuze igcobe. Kodwa emuva emuva kwe- chlorine gland. Kudingekile ukugcwalisa itanki ngokufaka imifino ngamanzi bese ufaka isipuni nge-slide ye-chloride ene-ferric. Qaphela, ngoba ukusabela kwamakhemikhali okuzokwenzeka kuyokwenzela ukushisa kakhulu, futhi isisombululo esilandelayo singase siphinde siphalaze kancane. Yebo, konke kuhlanganisiwe. Letha umunwe wakho kwisisombululo bese uqinisekisa ukuthi akushisi kakhulu. Bese ubeka lo msebenzi osebenza kuyo, mhlawumbe uhamba phansi - ukuze ulale phezulu. Okokuqala uzobhukuda notshani. Ngokuhamba kwesikhathi, ugoba. Bese uvula i-PCB ngokukhupha bese uyibeka esixazululweni. Ngesinye isikhathi, isitsha esinalo kufanele sisintshenziswe ekuqothuleni ithusi eliqhekekile ukusuka phezulu. Uma kubonakala ama-bubbles, susa ibhodi, hlambulula futhi uqhubeke uhlanganisa. Kuye ngokushisa kwesisombululo kanye nokuhlushwa kwayo, le nqubo ingathatha cishe ihora elilodwa.

Hlanza umsebenzi we-toner

Manje sibhekene nenkinga yokuhlanzeka. Kukhona izixazululo ezikhethekile kulokhu, kodwa abatholi ukubuyekezwa okuhle, futhi abantu abaningi bakhetha indlela yokumisa ithoni. Kulokhu, kunconywa ukuthi usebenzise ama-dishwashers wokugeza izitsha, ezinganikeza umphumela omuhle.

Ukushayela

Kufanele kuqaphele ukuthi, ngokuyinhloko, lokhu kuyindaba yokuthandwa ngabanye. Kodwa njengoba kunconywa kungenzeka ukuba ukweluleka ukusetshenziswa kwe-micromotors ye-DPR kanye namahlombe we-collet angaguqulwa. I-drill ingakhethwa kumamitha angu-0.8 - ezimweni eziningi lokhu kungaphezu kokwanele.

Tinning

Uma ufaka ibhodi lesifunda eliphrintiwe, udinga ukuwageza ngesipho. Bese ushayela ucingo lokuhlanza, ugeze futhi usule. Khona-ke kufanele ihlanganiswe nesisombululo se-rosin sokuphuza utshwala. Ungakwazi futhi ukufihla ibhodi ngamanoni asebenzayo e-Vaseline. Yeka ukuthi isilima sasingazwakala kanjani, kodwa into ewusizo. Amafutha abeka ungqimba omncane, awugcobe kahle. I-iron soldering kufanele ifakwe ukuze izimbobo zingagcinwa. Uma lokhu kusengenzeka, ke sithatha i-toothpick yokhuni, sishisa indawo "engcolile" futhi siyihlanze.

Izincomo zokusebenza ngamabhodi wesifunda aphrintiwe

Njenge-solder, ungeluleka i-PIC-61. Yenzelwe ukusebenza ngama-circuits ezimweni lapho ukushisa okungavumelekile kungamukeleki. Futhi uma lokhu kwenzeka, ke amathrekhi we-PCB angasuswa. Ekugcineni, singasho ukuthi le nqubo ibhekwa njengokubukeka okunzima. Kodwa lokhu kuyisiphakamiso esikhohlisayo. Ngikholelwa, uzoba nesikhathi esiningi sokudala umdwebo omuhle kunebhodi lesifunda eliphrintiwe. Ungaphinde unikeze iseluleko ngesikhathi sokubamba: iqiniso liwukuthi uma ushiya i-PCB isisombululo amahora ambalwa, ngisho nezindawo ezivikelwe i-toner ngeke zigcinwe. Ngakho-ke, kuyinto efiselekayo kakhulu ukuhambisana nemikhawulo yesikhathi eshiwo kulesi sihloko.

Izici

Kumele kuqashelwe ukuthi ubuchwepheshe be-LUT bukuvumela ukuba uthole imiphumela emihle ngokwemigomo yokuchithwa. Ngakho-ke, abanye abanikazi ngosizo lwakhe baye bafunda ukusika izinhlamvu nezinombolo, ubukhulu bawo obungama-0.3 millimeters! Ikhwalithi yomsebenzi emangalisayo! Yiqiniso, ukuze ufeze, uzodinga ukuqeqeshwa nesipiliyoni, noma kunjalo, njenganoma iyiphi insimu yomsebenzi.

Isiphetho

Kumele kuqashelwe ukuthi ubuchwepheshe be-LUT bokukhiqiza amabhodi wesifunda abaphrintiwe kabili abufani kakhulu nezinqubo ezichazwe kulesi sihloko. Yiqiniso, kuyodingeka wenze kube nzima kakhulu, futhi usebenzise isikhathi esengeziwe - kodwa umphumela wokuphela uzobe uwufanele. I-technology ye-LUT ikuvumela ukuthi udale amabhodi wesiphaphamtjhini aphrintiwe ngokushesha futhi ngempumelelo kuwo wonke ama-circuits. Uma ekuqaleni okuthile kungasebenzi, kufanele kukhunjulwe ngaso sonke isikhathi ukuthi isipiliyoni sizokuvumela ukuba uqonde lokhu. Ngakho-ke, udinga ukucabangela amaphutha akho, ufunde kuzo futhi uzame futhi.
