Ephrintiwe wesifunda ibhodi zinokusetshenziswa okuningi kwezobuchwepheshe. Kodwa-ke, kubiza kakhulu ukwenza ukuhlolwa komqondo ngaphambi kokuthuthela ekukhiqizeni i-PCB. Amabhodi wesibonelo we-PCB avumela imibono ukuthi ivunyelwe ngentengo ephansi ngaphambi kokuba kukhiqizwe inguqulo ephelele yokuphrinta.

Kulesi sihloko, sizokhuluma ngezinhlobo ezahlukene ezitholakalayo nokuthi siwasebenzisa kanjani amabhodi wesibonelo we-PCB ukuhlela imiklamo yokugcina yebhodi lesifunda.

Indlela yokusebenzisa i-PCB prototype board

Ngaphambi kokuthi ufunde kabanzi mayelana nokuthi ungalisebenzisa kanjani ibhodi lesibonelo le-PCB, kufanele uqonde izinhlobo ezahlukene zamabhodi wesibonelo ayatholakala.

Ipuleti Perforated

Ukusebenza kwamabhodi kungenye yezinhlobo ezitholakalayo zamabhodi wesibonelo. Lesi sigaba saziwa nangokuthi idizayini ye- “per-hole pad”, lapho umgodi ngamunye unephedi yawo yokuqhuba eyenziwe ngethusi. Usebenzisa lesi silungiselelo, ungahlola ukuxhumeka kwe-solder phakathi kwamaphakethe ngamanye. Ngaphezu kwalokho, ungakwazi ukufaka ucingo phakathi kwamapayipi ngocwecwe olubunjiwe.

Ipuleti lomugqa

Njengamanye ama-PCBS ojwayelekile, i-plugboard nayo ine-setup ehlukile. Esikhundleni sephedi yokuqhuba eyodwa yokugcotshwa ngakunye, imichilo yethusi isebenza ngokulingana nobude bebhodi lesifunda ukuxhuma izimbobo, yingakho igama. Lezi ziqeshana zithatha izintambo ongazinqamula futhi.

Zombili lezi zinhlobo ze-PCB prototypes zisebenza kahle ebhodini lokuhlela. Ngenxa yokuthi izintambo zethusi sezixhunyiwe, ama-plugboards nawo alungele ukuhlela amasekethe alula. Kunoma ikuphi, uzosebenzisa i-prototype plate welding kanye ne-prototype plate wire ukuhlola amabhodi angahle abe khona.

Manje usukulungele ukufunda okwengeziwe mayelana nokuthi uyisebenzisa kanjani ibhodi yesibonelo ngokuningiliziwe.

Ukuhlela

Noma ukwazi ukusebenzisa ibhodi lesibonelo le-PCB, awufuni ukugxumela ngqo ku-prototyping. Yize amabhodi wesibonelo eshibhile kakhulu kunamabhodi wesifunda aphrintiwe, asenokucushwa okuhlala isikhathi eside. Ngaphambi kokuqala ukubeka izingxenye, kufanele uchithe isikhathi esithile esigabeni sokuhlelela ukuze uzitholele imiphumela emihle kakhulu.

Indlela eqondile yokuqalisa ukusebenzisa uhlelo lokuhlela lwebhodi lesifunda kukhompyutha. Isoftware enjalo ikunikeza inketho yokubona ngeso lengqondo isifunda ngaphambi kokubeka phansi noma yiziphi izinto. Qaphela ukuthi ezinye izinhlelo zisebenza kahle ngazo zombili iPerf neStripboard, kanti ezinye zisebenza ngohlobo olulodwa kuphela, ngakho-ke hlela ukuthenga amabhodi wesibonelo ngokufanele.

Uma ufuna ukusebenzisa isixazululo esingezansi sedijithali, ungasebenzisa futhi iphepha eliyisikwele ekuhlelweni kwebhodi lesibonelo. Umqondo ngukuthi yonke indawo lapho imigqa iwela khona ingumgodi ebhodini. Izingxenye nezintambo kungadonswa. Uma kusetshenziswa amabhodi wokuhlubula, kuyasiza futhi ukukhombisa lapho uhlela ukuphazamisa khona.

Izinhlelo zedijithali zikuvumela ukuthi uhlele imibono ngokushesha, kepha okuqukethwe okudwetshwe ngesandla kungakusiza ukhombe amaphrojekthi ngezindlela ezahlukahlukene. Kunoma ikuphi, ungangeqi isigaba sokuhlela, ngoba ungonga isikhathi nomzamo lapho wakha i-Protoboard.

Ukusika ibhodi lesibonelo

Nge-Protoboard, awudingi iphepha lonke. Njengoba amabhodi angahluka ngosayizi, kungadingeka ukuthi usike elilodwa. Qaphela, kepha, njengoba le nqubo ingaba yinkimbinkimbi.

Ingxenye yesizathu kungenxa yezinto ezisetshenzisiwe ebhodini lesibonelo. Idizayini ivamise ukunamathisela iphepha nge-resin emelana nokushisa okunamathisela ngomlilo, okuwusizo kakhulu uma ungena kulesi sigaba. Okubi ukuthi le resin ingaphula kalula ipuleti lasekuqaleni, ngakho-ke kungcono ukuthi uqaphele kakhulu.

Enye yezindlela ezisebenza kahle futhi ezinembile ukusika ibhodi lesibonelo ukusebenzisa irula nommese obukhali. Ungasebenzisa onqenqemeni njengomhlahlandlela wokusika imigqa lapho ufuna ukusika khona ibhodi. Phinda ngakolunye uhlangothi, bese ufaka ibhodi lesibonelo onqenqemeni lwendawo eyisicaba njengetafula. Ungabamba ibhodi ngobunono ngokuya ngamamaki akho.

Ochwepheshe basikisela ukuthi ukuphuka okungahlanzekile kungatholwa ngokumaka eceleni komgodi ebhodini, ngoba alikho ibhodi lesibonelo elinjalo elingaphuka futhi liphule kalula.

Amasaha ebhendi namanye amathuluzi ebhendi angasetshenziswa, kepha lawa mathuluzi kungenzeka kakhulu alimaze ibhodi lesibonelo kule nqubo.

Ibhodi lesinkwa ukukhumula ibhodi

Uma ngabe wenze noma yimuphi umsebenzi ku-PCB eyisibonelo, kungenzeka ukuthi uhlangabezane nebhodi lesinkwa. Lawa mabhodi wesibonelo alungele ukwakha imiklamo ngoba ungahambisa futhi ushintshe izinto ukwakha amapulani. Amabhodi wesinkwa nawo angasetshenziswa futhi.

Mayelana nalokhu, ukwakheka kwengxenye kungahanjiswa kubhodi yomugqa ukuze kuhlolwe okunye. Ngaphezu kwalokho, amabhodi wesibonisi abunjiwe futhi anemingcele akanciphisi kakhulu ngoba ungenza ukuxhumana okuyinkimbinkimbi ngokwengeziwe. Uma uhlela ukusuka ebhodini lezinkwa uye ebhodini lokuhlubula, ungasiza ukuthenga ibhodi yokuhlwaya eqondisayo noma ukubhubhisa umkhondo webhodi lomugqa.

Uma ufuna amasekethe wesikhashana abe nokumiswa okuqinile nokuhlala unomphela, ukuhambisa izinto kusuka kwesinkwa kuye ebhodini lokuhlubula kungenye yezindlela ezilula kakhulu.

Phula amamaki webhodi yomugqa

Njengoba kushiwo ngaphambili, i-ribbon-board PCBS inemichilo yethusi ezansi esebenza njengokuxhumana. Noma kunjalo, awudingi ukuxhuma zonke izinto ngaso sonke isikhathi, ngakho-ke uzodinga ukweqa le mikhawulo.

Ngenhlanhla, okudingayo yi-drill. Ukuphela kokufanele ukwenze ukuthatha i-4mm drill bit bese ucindezela i-nib emgodini ofuna ukunqamula kuwo. Nge-twist kanye nengcindezi encane, ithusi linganqunywa ukuze lenze umugqa wesithiyo. Lapho ufunda ukuthi ungalisebenzisa kanjani ibhodi lesibonelo elenziwe kabili le-PCB, qaphela ukuthi ucwecwe lwethusi lukhona ezinhlangothini zombili.

Uma ufuna okuthile okuthuthuke kakhulu kunokujwayelekile, ungasebenzisa amathuluzi athile ukunqamula lokhu kuxhumana, kepha indlela ye-DIY isebenza futhi.

isiphetho

Ukwazi ukuthi ungawasebenzisa nini futhi kanjani amabhodi wesibonelo kuyikhono elibucayi kunoma ngubani ofuna ukuklama nokuhlola amabhodi wesekethe ngaphandle kwezindleko zokuwaphrinta. Ngamabhodi wesibonelo, ungenza igxathu elikhulu ekuqedeleni umkhiqizo wakho.
