Ephrintiwe wesifunda ibhodi have many uses in technology. Kodwa-ke, kubiza kakhulu ukwenza ukuhlolwa komqondo ngaphambi kokuthuthela ekukhiqizeni i-PCB. PCB prototype boards allow ideas to be approved cheaply before a full print version is produced.

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

Indlela yokusebenzisa i-PCB prototype board

Before you can learn more about how to use A PCB prototype board, you must understand the different types of prototype boards available.

Perforated plate

Performance boards are one of the available types of prototype boards. 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.

The strip plate

Njengamanye ama-PCBS ojwayelekile, i-plugboard nayo ine-setup ehlukile. Instead of a single conductor pad for each perforation, copper strips run parallel to the length of the circuit board to connect the holes, hence the name. Lezi ziqeshana zithatha izintambo ongazinqamula futhi.

Both types of PCB prototypes work well on the planning board. 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

Even if you know how to use a PCB prototype board, you don’t want to jump right into prototyping. Although prototype boards are much cheaper than printed circuit boards, they still have a more durable configuration. 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. If stripper boards are used, it is also helpful to indicate where you plan to interrupt the stripper.

Digital programs allow you to edit ideas faster, but hand-drawn content can help you target projects in different ways. Kunoma ikuphi, ungangeqi isigaba sokuhlela, ngoba ungonga isikhathi nomzamo lapho wakha i-Protoboard.

Cutting prototype board

With a Protoboard, you probably don’t need a whole sheet of paper. Njengoba amabhodi angahluka ngosayizi, kungadingeka ukuthi usike elilodwa. Be careful, however, as this process can be complex.

Part of the reason is because of the materials on the prototype board. 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.

One of the most efficient and accurate ways to cut a prototype board is to use a ruler and a sharp knife. Ungasebenzisa onqenqemeni njengomhlahlandlela wokusika imigqa lapho ufuna ukusika khona ibhodi. Repeat on the other side, then place the prototype board on the edge of a flat surface such as a table. Ungabamba ibhodi ngobunono ngokuya ngamamaki akho.

Experts suggest that a cleaner fracture can be obtained by marking along the position of the hole in the board, because there is no such stable prototype board that can break and break easily.

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

Bread board to strip board

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. If you plan to move from breadboard to stripper board, you can help purchase a directional matching stripper board or destroy stripper board traces.

If you want temporary circuits to have a more robust and permanent configuration, moving components from the bread to the stripper board is one of the most convenient ways.

Phula amamaki webhodi yomugqa

As mentioned earlier, ribbon-board PCBS have copper strips at the bottom that serve as connections. 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.
